Bimbo Formula, Hits the Spot | free mind control stories

As soon as I entered the house I saw Matilda sitting at the kitchen table.

Dammit, I thought. I had rented a porn video. I wanted to watch it. I wouldn't be able to do that with Matilda studying in the kitchen.

It wasn't that she didn't know about my porn habit. She did. It's that it would create noise, and Matilda hated too much noise.

She was always studying. She was the smartest person I knew.

"I'm home," I said.

Matilda sat at the table. She had a pile of books in front of her. Two were open. She was scribbling furiously on a piece of a paper. I stepped nearer and looked down. It looked like chemical formulas.

Both Matilda and I were students at the local university. But she was a much better student than I was.

We'd lived together since we were both small kids. Matilda's parents had died in a traffic accident, and my parents had adopted her.

"What are you doing?" I asked her.

She ignored me. But she tensed up at my question.

I looked closer. On the table were two small vials of a bubbling pink fluid. I reached down in front of Matilda and picked one up to examine it.

"Don't touch that!" She said. "Can't you see I'm working?"

I put it back down on the table. I raised both my hands in a gesture of innocence.

"What is it?" I asked.

"On the street, they're calling it Bimbo Formula XXX," she said.

"What? You got a hold of some?" I said.

"Yes. I'm trying to determine what its health impact might be," she said.

"Did you take a sample of it?" I asked.

"I had a third vial that I put under the microscope at school," she said. "Now, I'm just trying to determine what the consequences of drinking it would be."

"Pretty good from what I've heard," I said.

Matilda let out a long sigh. She threw her pencil down. She looked at me. She had thoughtful green eyes. She had straight brown hair. Even though she was nineteen, she was so thin that if she had short hair she could have passed for a boy.

"Ha. I know what's on your mind," she said. "It's what's always on your mind. Don't you understand? I'm actually curious about this. I'm objective. I have a scientific mind. I could care less about its other properties."

"Sure," I said. "But what better way to learn about it, than to try it. Or heck, just test it on me."

She rolled her eyes.

"I'm not going to take it," she said, and then added, "And neither are you."

"Are you afraid you won't be able to control your sexual desire," I said. "From what I've heard the stuff is pretty intense."

Matilda looked at me. She was disgusted. She pointed her finger at herself.

"Me, not be able to control my desires?" She said, "Not gonna happen. Got any other good jokes."

I shrugged. I left her to her studies. I went into the living room, which was adjacent to the kitchen. Whatever, I thought.

We were as close as a brother and sister, maybe that was why she was always so dismissive of me. Someday, I would show her just how important I could be to her. Someday.

Meanwhile, I sat on our old sturdy but soft sofa. I turned on the TV. I inserted my porn video. It was a classic. These days, it was very hard to find.

It was called The Spooner. It starred Jerry Long and Susie Smooth. I had wanted to watch it for the longest time. So far, no one had put a copy onto the Internet. Now finally I had my very own copy. I put it on fast forward. I wanted to get to the action.

When I started the video again, I realized I'd gone too far, because the action had already started. Things were already hot and heavy.

Susie Smooth lay on her side. She faced the camera full on. She was sensationally beautiful. She had what looked to be a wonderfully soft, pliant body. It was the kind of body that one would love to sink their hands into.

She had nice sized breasts, as well. Her body was softly curved in all the right places. She exuded femininity. I was willing to bet that she even smelled nice, as well.

As I said, she lay on her side. From behind her, Jerry Long had her in the spoon position. His cock had entered her pussy, and slowly, he pumped her.

The smile on Susie Smooth's face. She looked to be really enjoying herself. And Jerry Long had such a fine pace going, not too fast, not to slow. A casual, enjoyable pace. He slid his cock in and out of that cute pussy. All the while her soft ass sliding against his pelvis each time he thrust.

Jerry Long totally enveloped Susie Smooth from behind. And while he did so, he wrapped his hands around her tits and held onto to them as he fucked her.

How could he possibly fuck Susie Smooth at such a leisurely pace? I'd have been mad with desire if it had been me!

What must it have been like for Jerry Long to have had his pelvis sliding up and down Susie Smooth's ass like that, with his cock simultaneously sliding in and out of her slick pussy? And all the while his hands feeling up her wonderful tits.

I felt my cock harden. I felt dizzy just watching this action. It was all so wonderfully slick. Jerry Long and Susie Smooth moving so deftly together. The harder my cock got, the more I melted.

Then, when Susie Smooth began to lick her lips and moan as Jerry Long slid in and out of her, I couldn't take it any longer. My hand slipped down to my cock. I stroked it.

"Mason!" Yelled Matilda.

I sighed. I really wanted to keep watching my porn video. But I put it on pause. I looked toward the kitchen door, which was still closed.

"What?" I yelled.

"What are you doing?" Said Matilda through the door.

"What do you think I'm doing?" I said.

"I can't concentrate. You're too noisy!" Said Matilda.

"I'll turn the volume down!" I said.

I lowered the volume. I started the video again. Jerry Long continued at his leisurely pace, sliding in and out of Susie Smooth's most excellent pussy. Oh, I so much wanted to feel Susie Smooth's ass sliding up and down my pelvis as I fucked her from behind in the spoon position!

Then, true to her name, Susie Smooth smoothly turned her head toward Jerry Long and stuck out her tongue. He greeted it with his mouth. So that now as he spoon-fucked her from behind, he also was French kissing her. It was insane!

How many sensations would that be? I considered it. Tongues against tongues. Hands-on soft breasts. Pelvis sliding up and down the smooth ass. And finally, cock sliding in and out of that pussy. Oh, and Jerry Long's balls bouncing up and down the sides of Susie Smooth's legs. This was enough to short circuit anyone!

I so wanted all this. It was exactly what I wanted.

Suddenly the door to the kitchen opened with a big whisk. I knew it was Matilda.

I didn't move. I kept my hand in my pants, my hand on my hard cock. I barely managed to stop stroking. I reached for the remote. I paused the video for the second time.

Matilda stormed in at me.

"How can I study with that racket?" She said.

But she shut up when she saw the video. She stared at the screen. The live action video had paused on one of Jerry Long's famous thrusts.

Matilda raised a single eyebrow curiously. She cleared her throat. She went to the sofa and sat down next to me.

She looked down and saw my hand was in my pants. She made a face of disgust. She reached down for the remote.

She unpaused the video. Then, she, too, watched as Jerry Long leisurely pushed his cock into Susie Smooth's pussy and slid it out.

Her breathing had increased.

I'd never done it with Matilda. We'd never had sex together. I'd thought about it. Despite how annoying she was, or maybe precisely because of it, I had wanted to fuck her before. It was true. I admit it.

But like I said, she had no figure at all.

I thought about trying to spoon her from behind. Her ass was as flat and boney as the rest of her. She had no breasts to speak of, so where would my hands go. It was useless.

As fond as I could be of her at times, and as irritating as she could be, making me want to fuck her all the more, I just couldn't see it happening between us.

All of the sudden Matilda turned off the video. She put the remote down on a table.

"Hey!" I said.

"Get your hand out of your pants. I need your help," she said.

"Really," I said. "My help?"

"Don't get too excited," she said. "It's an easy assignment. Even you can't mess it up."

"Thank you for your vote of confidence," I said.

She pointed to the phone.

"Do you see that?" she said.

"The telephone, right? I got it." I said.

I realized for the first time now that she had brought both vials of Bimbo Formula XXX with her into the room. She'd put them down on the small table in front of the sofa. She'd also brought a small voice recorder.

I'd been so involved in the video, I hadn't even noticed this before.

"I'm going to drink one of these vials," Matilda said. "I'm going to record any changes to my body or to my mental state. I don't anticipate any serious problem, but if something goes wrong, you'll need to call 911. Do you understand?"

"What are you going to do with the other vial?" I asked.

"Don't get any ideas," she said. "This is strictly science. This is all about increasing our knowledge of the world. Don't think I'm doing this because of any other reason. I'm certainly not interested in, well, you know."

"Okay, whatever," I said.

She picked up the voice recorder first. She switched it on. She spoke into it.

"Today is June 9. I'm Matilda Johnson. After having studied the chemical components of Bimbo Formula XXX, I have decided to try the formula on myself. While the accompanying physical changes will be welcome, I am a little concerned about potential psychological side effects. However, given my great intellect and degree of self-control, I imagine any such effects will not be too significant."

I stood by the phone. People had been talking about the formula for the last few days. There had been a big incident at the biochemistry laboratory. What actually had happened no one knew. But rumors about Bimbo Formula XXX had been circulating everywhere.

People said not only did it give a person the body of a sex god or goddess but that also it triggered deep uncontrollable desires.

Naturally, I watched Matilda now with great interest. What would happen if she drank it? This was actually kind of exciting.

Matilda uncorked the vial and drank it down. A curious look crossed her face, but nothing seemed to happen.

She spoke into her small voice recorder.

"I have now taken the formula," she said. "I feel nothing. The formula did taste rather good. Perhaps like a mixture of strawberries and cherries. It was, in fact, very sweet. I liked it."

She clicked off the voice recorder.

"You're okay?" I asked.

She nodded. She shrugged.

To be honest, I was worried about her. The instant she took the formula I realized how important she had always been to me, irritating or not. She was just like a genuine sister to me, even if we weren't related via blood. If something ever happened to her, I would have felt devastated.

She clicked on the voice recorder again. She began to speak into it.

"It's been several moments now, I feel no effect at all," she said.

Then she took in a big breath. She stood up.

She continued to speak into the voice recorder.

"Oh, oh, suddenly, I feel really, really good," she said.

Matilda looked at me. She smiled. I'd never seen her smile that way. It was a glorious, selfish, happy smile.

Her hands went to her body, even as she held the voice recorder.

"I don't think," she gasped. "I don't think I've ever felt this good."

Then, right before my eyes, her body began to shift and change. I don't know how else to describe it, except to say it was quite wonderful. Yes, scary at first, but it was so clear that the transformation was positive in every way.

She'd always been bony, thin, and flat. But she began to grow and to alter in all the right places. Her form became more sensuous and smooth. And suddenly she had tits, wonderfully round tits that pushed out from her t-shirt, and they began to grow.

"I seem to be changing," Matilda said to the voice recorder.

She could barely catch her breath so as to speak.

One of her hands went to her new, glorious, breathtaking breasts. She touched it and felt it. A nipple became erect through her T-shirt.

"I have tits and nipples and I feel, oh, God, I feel so horney. I...I..."

She looked directly at me. Her eyes were wide.

"I've gotta get laid. I've gotta get fucked. And fast!" She said.

She dropped the voice recorder.

I looked at her clothes. Her figure had become so prominent and brilliantly sexy that it had stretched her clothes well beyond the point of comfort.

She tore her T-shirt off. My God, the mounds she had under it. So big and bouncy and round. I immediately longed to put my hands on them.

Then, she undid the buttons on her jeans and slipped out of them. Her panties had stretched and torn. Her ass was now so curvy and pliant and soft and delicious. She tore off what remained of her panties.

"Look at me!" She said.

I did!

I felt so hard. I immediately wanted to come. I wanted to grab my cock and start pumping. I felt out of control.

Not only was Matilda now beautiful, but her smell! She gave off this barely detectable musk-like smell. It killed me. I wanted to fuck her right then and there more than I'd ever wanted anything.

She looked at me with that smile on her face. That sweet, sweet smile with just the right hint of badness in it.

Then she looked down at her new body. She had transformed into a sex goddess. Her hands slid up her sides, and she writhed under her own touch. She gasped as she felt her own tits.

"It feels so good," she crooned. "You can't imagine it."

Checking out her entire body, her hands went down to her deliciously curved ass. She ran her hands over it. For just a moment her hand gently caressed her pussy. She squirmed as she stood there naked in front of me.

"I'm wet," she said, looking at me desperately. "I've gotta get fucked. I've gotta get fucked now. I need the biggest cock there's ever been. I've gotta get jam-packed with a giant cock until I'm splitting. I've gotta. Oh, Jesus. What am I gonna do?"

She was desperate. She came at me. She started ripping at my shirt. I didn't fight her back. I helped!

I couldn't take it. She exuded a raw animal magnetism. It was irresistible. My cock was as hard as it had ever been before.

But then as soon as I was undressed, she stared at me and my hard cock. Disappointment fell across her face.

"No, it can't be," she said. "You're too small. Much too small. That cock won't do at all!

She whimpered. She whined. She needed it so bad. Then her eyes went to the remaining vial. She picked it up.

"Take it," she said, "Drink all of it. Quickly."

I didn't need to be told twice. I grabbed it from her, uncorked it, and drank it down. I took in a deep breath, trying to calm my raging lust.

I concentrated on the taste of the formula. It did taste good. Only to me, it tasted more like cranberries and apples.

I waited there trying to calm myself. Matilda stood so close to me now. I could feel the heat of her lust. She was so expectant.

Suddenly, I felt her hands on my cock. They didn't pump or move. They just held onto my cock tightly. It felt so intense.

"I want to feel your cock as it changes," she said. "I want to feel your cock as it gets bigger and bigger."

She had a such a crazy, marvelous, lustful smile on her face. I wanted to die I was so turned on.

"Okay," I said, nodding. "Great!"

This was Matilda. Sure she could irritate me like hell, but she was one of my favorite people in the world. She was just as much a sister to me as a real sister would have been. She was my best friend. And, now, she stood before me like a sex goddess. And here she was holding my cock because she wanted to feel it in her hands as it got bigger!

But at first, nothing happened. I was actually worried for a minute. Then, it washed over me. This intense sense of exhilaration.

"Wow," I said.

And then I could feel my muscles growing. I could feel my whole body changing, broadening, strengthening. My own curves becoming more and more masculine.

"Oh, yes! Yes! Yes!" said Matilda.

I could feel her anxious hands on my cock as it began to grow bigger, and bigger, and bigger. It felt so incredibly good to have her hands there as my cock grew.

"I love this cock. I love it," Matilda said.

I looked down. I now had the cock of Atlas. This was the cock that lifted up the world.

Matilda couldn't control herself at all. She'd gone down on her knees. Her hands were all over my cock, exploring it with her fingers, and with the smooth, soft, warm palms of her hand.

"Oh, it's so big," she crooned.

Her hands treated my cock like an irresistible pet. They were all over it. She slid one hand across the bottom, while her other hand came up over the top. She was head over heels in love with my cock.

She kissed the head of my cock. She gripped it firmly from below. She slowly began to pump it, luxuriating in how heavy it felt in the grip of her hand.

I moaned. With excruciating slowness, she pumped again.

"You are going to put this cock in my wet pussy and fuck the living daylights out of me. Do you hear me?" She said.

"Oh, yeah, that sounds like a marvelous idea!" I said.

But she just couldn't let go of my cock. The pull was just too irresistible for her. This time, she brought her lips to the head of my cock, and it disappeared into her mouth.

Then, with her hands, instead of pumping again, she just lazily let her palms slide across the base of my cock, then back again, then forward again. All the while sucking my cock's head with her mouth.

"Mmmm," she moaned, as she sucked.

I thought for sure I would explode. Normally, when I was this excited, just a girl touching my cock would have been enough for me to explode. And here was a sex goddess kneeling down in front of me, the head of my cock in her mouth as she gently stroked me back and forth with her gentle soft fingers.

Yet somehow I kept myself in check. Rather than just explode into a massive orgasm with cum shooting out in strings all over her face, I kept myself under control.

I suddenly found that I wanted to suck every bit of joy that I could get from this experience. I wanted to take it as slowly as possible and build to one of the most massive orgasms ever. This would be the orgasm of orgasms. And I wanted it to be the same for her.

I knew what I was going to do, but even as I formulated my plan, I was met by an all-new challenge. Her mouth slipped over not just the head of my cock, but its entire length. Matilda was deep throating me!

It's not like she was wild or desperate. She wasn't. She moved in languid joy. She wanted to totally luxuriate in the feel of my giant cock in her mouth. She wanted to taste every bit of it. She wanted to feel that heavy, smooth, delicious weight going down her throat.

Back and forth she carefully rocked. Her tongue always catching the base of my cock as she rocked backward and forwards. She was so in love with my cock!

I let this go on for as long as I dared. I knew that if I let her take it too far, then I would explode. There'd be no way to hold it back even with the endurance of a sex god. After all, she was now a sex goddess.

I gently guided her away from me. My mammoth cock popped out of her mouth.

"Oh, please, just a little more, just a little more," she begged.

"Just a few more licks then," I said.

And so I let her slide my cock back into her small mouth. And this time, she closed her lips as tight as she could, and she sucked deeply as she rocked back and forth, my cock sliding in and out of her mouth. She had such wonderfully thick lips. How utterly fantastic they felt as they traced the contours of my cock.

I took a deep breath and kept myself under control. But then sure that I'd had plenty enough, I eased her off my cock again. Then helping her up, I leaned her back onto the sofa. Then, I had her lie down.

With my hands, I spread her legs apart.

"You're a virgin," I said, surprised.

"Yes, and I need your cock," she said. "Hurry, Mason. I'm so glad it's you, not someone else."

"You mean you've been wanting this? From me?" I said.

"Don't be stupid, Mason, I've always wanted you," she said. "You're the only person who always puts up with me, no matter what."

"No matter what," I said.

I decided that I needed to make this a treat for her. Just using my newly enhanced sex god body would not be enough. I knew what needed to be done.

I spread her legs apart just a little more. I leaned in toward her pussy. I would take this ever so slowly. I would have her begging for my cock.

Carefully, I lay my hand on her pubic hair. Ever so gently, but with appropriate pressure, I scissored the area around the top of her pussy, so that her clit squeezed its way to the forefront.

I didn't even begin to lick yet. First I just let her feel the pressure of my squeeze. Then, gently, I slowly pulled up and down to stimulate the whole area. She writhed when is did this. Her body lightly spasmed.

I then wriggled the area I'd squeeze just a little bit more. At that, she released a gasp and a moan.

"What are you doing to me. I'm going to go crazy with pleasure!" She said.

"It's all just part of your research," I said.

"Oh," she moaned, "I liked it. I like this kind of research."

I carefully held the skin around her clit between my fingers. Then with my free hand, and a single finger, I moved it below the clit. I traced the wet, silky skin of her pussy there, just above her opening. My finger slowly went down, then I repeated the process. Each time she moaned and nearly spasmed.

"Awww!" she gasped.

I delicately again squeezed the skin around her clit. I pulled it and ever so gently jerked it. One more time she gasped. Her pussy at this point dripped. She was so wet!

With my free hand, I inserted two fingers into her dripping pussy. I pressed downward, and let them slide back and forth, then side to side. Her whole body trembled.

She reflexively began to contract her muscles. I stopped pressing. I waited. She relaxed. I began again with my finger massage of her inner pussy. I pressed gently down in the center. I leisurely slid my fingers to the sides. She shuddered!

"You're killing me," she said. "You're killing me!"

I let her relax for a moment. Then with my fingers still inside her pussy, I pressed them against the top of her wet vagina walls. I knew there was a spot there to find, and I wanted to find it.

She spasmed. Her muscles squeezed. I waited until she relaxed again, then with my fingers still in her opening, I began my hunt anew. Then, her whole pelvis suddenly thrust up, and I knew I'd found the spot. I relaxed my fingers. I slowly pulled them out.

I would remember that spot.

For now, I leaned in toward her pussy with my mouth. The smell was overpowering and delicious. I felt dizzy at how wonderful the smell was. Oh, I loved her pussy every bit as much as she loved my cock.

I tasted the whole area surrounding her pussy. I took my time. Then, I tasted the walls and lips of her pussy. Finally, I moved toward the clit, toward the nub, where all her pleasure nerves met. It was such a small little sensitive button.

I lay my tongue on it. I didn't flick or flail with my tongue. I used my whole mouth, and with my tongue right on that point, I sucked. It was so delicious!

She responded reflexively. She pushed her pelvis against my tongue. She wriggled her own body so that her nub slid against my tongue in mounting gyrations.

"It's so good," she moaned. "It so, so, so, so good. Oh, God, I love your tongue. Right there. Right there. Yes! Right there!"

Suddenly she began to orgasm. She gushed. She flooded. Her love juices poured out as she spasmed and gasped and moaned all at once.

"What did you do? What did you do?" she sighed.

But I wasn't at all finished. I crawled up to her on the sofa, and I embraced her from behind. I spooned her. We were a perfect fit for each other. It was as if our bodies had been made for one another.

For the moment, Matilda had spent her energy. But I could wait. I knew that soon she'd be ready to go again.

My own cock was as solid as steel. I was desperate to fuck Matilda. But I commanded myself to wait until just the right moment. No sooner.

For now, I simply felt her sides with my hands. It was like a touch-massage. I gently traced out her delicate and beautiful form. The palms of my hand slid over her goddess body, touching all of her delicious curves.

There was no rush at all to my actions. I simply reveled in how good her velvet skin felt under my touch. She purred as I did so.

Eventually, my hands found her breasts. I massaged them patiently. I felt for her nipples and pinched them until they were erect. Even while I massaged her breasts, I kissed her along the nape of the neck. I played Matilda like the fine instrument of love that she was.

I took my time. There was no rush at all. I would wait until she was ready. How long did this touching and kissing go on? Minutes? hours? days? I didn't know.

Time just passed and neither of us cared. But finally, I could feel her again growing excited. She turned her neck and leaned back so that I could kiss her lips and tangle our tongues. I knew now that she was ready for what I had planned.

I'd been spooning her the whole time. My pelvis had been up against her ass. My huge cock had been right between her legs, hard as a rock, patiently waiting for some action.

Now, I had to move adroitly and just right. I couldn't use my hands to guide my cock to her pussy. My hands were too busy elsewhere providing Matilda with pleasure.

So, instead, I had to shift my legs, my pelvis, my whole body, just right, so that the head of my cock could find her opening. Finally, I'd discovered it. I could feel my cock right there, at the exact right spot. I waited for the time it takes to exhale, then pushing, I inserted the head of my cock inside her pussy.

"Oh, oh, yes," she said.

Her virgin pussy was so tight. But it's wet velvet sides felt so good hugging my cock that I thought, now it is Matilda that is killing me.

With my cock now carefully inserted, I just lay there, barely moving. I would make her wait. I would build the anticipation. Reflexively, she began to move, herself, grinding into me, wanting me to plunge my cock deeper inside her.

Oh, yes, she was ready.

I knew just where her special spot was. And from behind, pushing in and out of her pussy, I knew I could put just the right amount of pressure there. That is what I did.

I didn't even need to penetrate her very deeply to do this. I could just slide in and out a few inches, pressing against that spot. And when her own muscles contracted tightly around my cock, gripping it tightly with her pussy, I'd stop and wait. Finally, she would relax. Then I would start the process again.

I reached out and covered Matilda's mounds with my hands. My palms were over her nipples. That's when I realized, I was in that dream spot, that place, I'd always wanted to be.

My hands were full of tits, my pelvis was sliding up and down a curvey velvet ass, my cock was inside a tight pussy. Matilda leaned back and turned so our tongues could once again touch.

Everything was perfect like this.

God, how I loved her ass sliding up and down my pelvis with each thrust I made. My cock was so incredibly big that it filled Matilda's pussy to its maximum width.

It all felt so insanely good. How long did this go on? A few minutes? A few hours? A few days? Did we pass through eternity and come back again? That's how it felt. It felt like forever. Part of me would have liked to stay in that heavenly position until the sun burned out.

But yet another part of me began to yearn for something more. For something harder, faster, deeper.

When Matilda spoke, it was almost as if she could read my mind.

"I want your whole cock inside me," she said. "I want you inside me all the way to the hilt, pumping, and pumping, and pumping. I want that giant cock of your taking up every little bit of space in my pussy!"

Carefully, without my cock ever leaving her pussy, I shifted her body and my own. I stayed behind her, barely changing our relative positions.

Matilda understood instinctively what I was doing. As I altered my body position, she altered her own to keep us entirely in tune.

The whole procedure only took seconds. Matilda was now on all fours, stooped low in the front, with her ass stuck up high. I was right behind her. My cock still inside her tight, dripping pussy.

Once our new position was entirely secure, I began to pump her in earnest. I kept only a slow pace at first. Each stroke drove me deeper and deeper inside her until finally, I was smacking her each time I drove inside her pussy.

Smack, smack, smack.

As I looked down on her exquisite form, I felt as if I were the king of the world!

Smack, smack, smack. I ground into her.

"Harder, harder," she screamed.

I began to lose myself.

"Fuck me hard," she screamed.

I no longer realized who I was or who I was with or what I was doing. I just wanted to fuck and to fuck hard. I completely and utterly lost myself.

I began to grind into her with long powerful thrusts. These were no longer smacks, these were bangs.

Bang, bang, bang.

I'd completely lost myself. Vaguely I thought, what if I hurt her.

But she only screamed for more.

"Yes, yes. Fuck me harder than you've ever fucked. Harder, harder, harder," she screamed at me.

That was it, I lost the last tiny bit of my control. I thrust into her like a wild lion in heat. I thrust into her like a wolf gone mad with lust. My whole body broke out in a sheen of sweat. Her own ass glistened as I repeatedly banged into it. Our sweat splashed and mingled with each thrust.

And then I knew I was coming. I knew it, and I thrust only harder as it began to happen.

"Ahhhhhh!" I hollered like a wild man as I pounded away at her ass.

Then, stream after stream of cum began to shoot from me, deep inside Matilda's pussy.

"Yes, yes, yes," and her whole pussy began to contract violently around my cock. She was coming at the same time as I was until we were both coming with complete and depraved abandonment.

We screamed. We hollered. We writhed. We came and we came and we came. And when it was finally over, I simply collapsed in exhaustion on top of her.

We both then lay there, wet and entangled. Neither of us able to move for a long time.

Eventually, after we'd recovered, Matilda reached her arm down off the sofa and found something.

She laughed.

"What is it?" I asked.

"It's my voice recorder," she said. "It's been on this whole time!"

"Oh, you've been recording us for science," I said.

She giggled.

"Knowledge is invaluable," she said.

"In that case," I said, "keep it on. I think we've still got more to contribute."

Our eyes locked for a moment, then my lips fell onto hers, and I began to devour her again.
