Gym Buddies

Lily slept soundly that night. She and her daughters had spent the entire day fucking the newest member of the house until he was more cum rag than human. After about 5 hours of non stop penetration, he finally passed out. They had continued to use his limp body for hours after that.

Since their transformation, the girls had been **** to use onaholes that tore and broke under the strain of their superhuman cocks. They were pent up and the epic fucking of the previous day was the first real release they had gotten in weeks.

It was for that reason that Lily rested so deeply, her lust had finally been slaked, at least for now.

The other reason she slept so well is that it was her turn to use the toy for the night. The girls had devised a little schedule in order to share their spoils equitably. They had bickered and argued over the details, but finally they had come to an agreement. Tonight, Lily had the boy, and she was enjoying some quality time in bed with him.

She had cleaned him up and drained as much cum as she could from his holes. After their earlier session, it looked as though he would never be clean again. There is, however, nothing like a mother’s touch, and soon he was looking good as new.

Lily slept that entire night with her cock deep inside his colon, his head nested in between her mammoth jugs. In her sleep, she humped and thrust her hips instinctively, cumming three different times in the deepest reaches of his ass. Her primal desire to breed was not staved off by sleep. After each time she came, her cock would soften, allowing globs of thick cum to seep out between them, soaking the bed and gluing them together as it dried.

This would have been a problem, except she often experienced night time emissions regardless. It was just nice to have a place for most of her spunk to go.

They both woke up together as the soft light of morning came wafting in to meet their lidded eyes. Lily smiled as she felt the warm, wet embrace of her favorite hole on her dick. She pulled down the blanket to admire him. It was impossible to miss the gigantic bulge that ran up his entire abdomen. The unmistakable shape of a penis was clearly visible in his stomach. It ran all the way up his abdomen, stopping just below his chest where the shape of her bulbous head was visible.

As he awoke, his insides twitched in the pleasure of being speared by twenty inches of hard dick meat. His twitches squeezed her cock and drove her arousal to unsustainable levels. Still inside, she flipped him onto his face and began to drive her cock into the hole that it had inhabited all night. He was still so full of her cum that it squelched loudly as she thrust.

Before long she was ready to blow again. Just as she was picking up the pace there was a loud knock at the door.

“Mom! It’s my turn!” Yelled Jenna. C’mon, I can hear you in there. We have a schedule for a reason!”

“Just . . . just a second dear!” Lily panted out between her thrusts. “I’m. Almost. Doooooone!”

With that she blew another massive load inside him, collapsing on top of him as she did. Their sweat and her cum nearly glued them together. But shortly she was standing up and carrying his dripping, limp form to the door.

“Here you go sweetie, sorry for going a little long.”

“Mom what the fuck is this?” Said Jenna. Then turning toward the hall she yelled to her sisters, “We're gonna need to add a rule about cleaning him between shifts, this is just ridiculous!”

After a quick shower and drain, he was looking spic and span and even semi conscious. As Jenna washed him while they showered together, he kept trying to suck at the tip of her cock. She allowed him to lick and suckle briefly, but soon interrupted him to return to washing. She was eager to get down to business, but she wasn’t opposed to getting her dick sucked a bit either.

After drying off, Jenna led him to her room.

“I’ve got a little surprise for you!” She said, pulling out a shopping bag and holding it up.

Out of the bag she took a dark blue one piece bathing suit in which she dressed him. It was a little too small, but that just added to the charm. The elastic in the back pushed into his soft fleshy ass, while his little tits filled out the front quite nicely.

For herself, Jenna put on a tight black sports bra and compression shorts. Her top squeezed her ample bosom as flat as it could. Still her breasts looked massive and the excess flesh was desperately trying to spill out the top. Her shorts had a small customization as well. There was a custom stitched hole in the front that her cock and balls fit perfectly though. A pair of sneakers and pony tail completed the look.

“What do you think? I had these made custom.”

He only moaned and crawled over to her, putting one of her massive balls into his mouth and suckling.

“I bet you’ve got a lot of cum saved up in here for me don’t you?” He said. His mind was no longer just blank. It was being rewritten with his new personality. It wasn’t much of a personality to be fair. It was just, cum hungry futa cockslut, but it was his new personality nonetheless.

“You’ve got a bit of a one track mind, huh? Well I’ve got no problem with that. Just know that when I have you, we’re gonna be training. I’m working hard to be the fastest and the strongest I can be. We should all strive to be the best at what we do. For me, that’s working out and fucking. For you, well I suppose taking dick is all you’re really good for now. And to be honest you’re already pretty good at that. Umm, but you could still be better, OK? So let’s get to work.”

By the time she had finished her speech, he had already moved to her shaft and was working his hardest to suck the sperm from her pisshole. He hadn’t heard a single word she said. She grabbed his shoulder length hair and pulled him off of her dick. She dragged him over to the exercise bike.

Jenna’s room was a reflection of her devotion to fitness. It was filled with exercise equipment, and the floors were mostly covered in soft squishy exercise mats.

As they got to the bike, it was immediately clear that something was a bit off. First of all, the bike had no seat. In its place, was a makeshift harness. Jenna laid him across the bike on his back, his head going where the seat would normally go. His feet rested on the handlebars with his body laying in a sort of cradle that was attached to the frame of the bike. She strapped him in quietly and prepared to mount her trusty steed.

“Ready or not, here I come!”

Jenna stepped out of her shorts and swung her leg over the bondage equipment that she had disguised as a bicycle. The bicycle seat grunted as she sat down. Her firm bottom came to rest right on his face, her asshole lined up perfectly with his mouth.

“Just how I drew it up.” She said to herself, gleaming with pride.

As soon as she came down, he began to lap at her bare ass. A shiver ran up her spine and she ground down with her weight, showing how much she liked what he was doing.

Though incredibly fit, Jenna wasn’t light. Her body was packed with dense, striated muscle. Hell, even her cock weighed as much as his arm. This is all to say, that being her bicycle seat was not an easy job. She had only just sat down and already he was beginning to feel uncomfortable. Still he dutifully licked her rosebud as he knew she wanted, hoping he might be rewarded for his efforts.

Not keen to waste any more time, she got started on her morning workout. Spinning her legs, she began to pedal faster and faster. Every time she spun her legs, her ass rubbed into his face.

After five or so minutes, sweat started to drip down her rippled back. It all made its way down to her toned crack, where it ended up in his smothered face. It was growing hot and sweaty on the bicycle, and he could barely breathe. Despite this, he doubled his efforts. He stuck his tongue as far as it could go into her shitpipe. He wiggled and squirmed his little tongue, eliciting moans of pleasure from his sister.

“Mmm. What a good little bicycle seat. This might be the best ride I’ve ever taken. I could certainly get used to this.”

Jenna continued to pedal. Before long, the two of them were drenched. Jenna had so enjoyed getting her ass eaten, that she had grown quite hard. As she bobbed up and down on her brother’s face, her bare cock bobbed with her. It kept slapping against his stomach, leaving a daub of thick, white precum wherever it touched. Soon his entire swimsuit was soaking wet and sticking to his skin.

After about twenty minutes, an alarm went off on the exercise bike. Clearly this was the sign for a high intensity interval, as Jenna began to pump her powerful legs harder and harder. Her sweaty thighs and ass were absolutely enveloping him, **** him out and drenching him in ass sweat. Her heavy nutsack was hot and hung exceptionally low. It dripped her potent and musky ball sweat all over his face and neck.

Suddenly, Jenna stood up. Still pedaling, she raised her ass off the seat and continued her high intensity effort. Tasting his first breath of fresh air in twenty-five minutes, Jenna’s bike seat gasped and panted. The combination of a lack of oxygen and Jenna's powerful pheromones had put him into a barely conscious trance like state. The shock of cool air was such a change from the sweaty ass chamber that it shocked him back to alertness

The air had awoken him just in time to see Jenna’s rock hard knob coming straight for his face. He did not let her down, opening wide to accept the hung jock into his mouth. Jenna raised her ass and rotated her hips down. To get the angle just right, she put her hands down on the drop bars and then slammed her cock home.She speared his throat, pedaling her bike the whole time. Her dick was sweaty and salty, but he barely had time to savor the flavor as she bottomed out and began to thrust.

Up and down, Jenna’s hips moved with the motion of the bike. Every time one of her feet reached the bottom of a pedal stroke, her cock bottomed out.

Jenna had been cycling for half an hour and she couldn’t last much longer at this pace. She doubled her efforts. Her stamina was buoyed by the wonderful wet sensation around her cock, and she began to chase her orgasm like it was another cyclist in a race.

Faster and faster she pedaled. Her body was like a machine. Her cock like the machine’s piston, being drawn in and out at an inhuman speed. Her whole body tensed, her balls drew up close to her body and she began to shake.

Cum erupted from the end of her dick. Her balls churned and twitched, pumping her thick sperm into the receptacle that she had strapped to her bike. As she came, the stimulation of her thrusting was too much for her sensitive cock. She tried to stop, but she couldn’t. The momentum of the bike made her continue to fuck his throat.

Her thrusts made even nastier sounds as she continued to fuck his cum lubed hole. He coughed and choked up her nut, drenching his own face in girl goo that mixed with the copious ass sweat already there.

Finally, she was able to stop, but it was too late. Jenna began to cum again.

“Holy shit! I'm cumming again!” Jenna screamed, but he didn’t need to be told.

This time she just rocked her hips as she came in his already cum filled stomach. Her feet came off the pedals. All of her weight was supported by her cock as it rested in his throat. She rode out her second orgasm while leaning the bike, her cock twitching and shooting out rope after rope. He moaned in pleasure, completely subsumed by her essence.

Jenna flopped off of the bicycle and lay down on the mat beside it, staring at the ceiling. Her softening cock slid over her thigh, spreading throat slime and cum like a snail trail that snaked almost to her knee.

She panted, catching her breath as she looked over at the bike. Her brother was, as usual, covered in sweat and cum. Even after being **** fed more baby batter than most whores ate in a lifetime, he was still desperately licking his lips and trying to get to the cum that had spilled onto his face. Jenna laughed at this and reached up to undo his harness. Sitting up, she lifted him effortlessly and put him on the ground. He immediately crawled over to her and began to clean her cum covered cock.

Jenna allowed this, closing her eyes as she laid back and let him suck the spunk off of her. His tongue ran over her shaft, lapping up the chunky reward that he was so happy to get. Her veiny cock throbbed and flexed in the afterglow of her orgasm. He was completely enraptured by the power and strength of her superhuman member. He basked in its splendor, rubbing his face on her, covering himself further in her fluids and scent.

Soon, however, he was interrupted. Jenna had caught her breath and she rose to her feet.

“Come,” she said. “We have more training to do.”

She scooped him up around the waist and carried him to an open part of the room.

“I hope you’re not too tired from that bike ride, because it’s time for squats.”

She turned her lovely assistant around so he was facing away from her. Then holding him up from the back of his thighs, she lined up her already turgid cock with his backdoor. She moved one hand in order to slide his suit to the side. Incidentally, his cute little cock popped out, revealing that he was hard as well, though the difference in size between their erections made it hard to imagine them ever being used for the same thing.

With nothing left in the way, her engorged tip was now pressed against his hungry opening. His sphincter was dilating in anticipation of the impending penetration. This was his purpose and his body was suiter better to no other task.

All of the sudden, with her hand moving his clothes and all the sweat and fluid that coated their bodies, he slipped from her hands.

In an instant he slid down her cock. With nothing else to slow him down, he descended all the way down her impressive length before slamming into her pelvis. His legs dangled and twitched below him, hanging at least a foot off of the ground. His insides were completely rearranged as they adjusted from being totally empty, to being thoroughly occupied by a huge veiny cock.

“Aaahhhh!” He let out a soft sissy moan as he squirted out a pitiful little orgasm onto the gym mat below them. As he came, his insides squeezed down on Jenna’s cock as if he was trying to milk her dry.

“Yeah, just like that, keep milking me. You love having my cock in your ass, don’t you? I bet you’ve been missing it haven’t you?”

“Mmmmff.” He couldn’t answer,being so overcome with the sheer amount of pipe being laid in his colon.

Jenna had completely let go after dropping him, and he was suspended only by the hardness and strength of her cock. To anyone who might have come in to see them, Jenna’s cock would have been completely hidden. It would have looked like he was simply dangling in thin air in front of her. They would have also noticed his face. Still sloppy and wet from his face fucking earlier, his mouth hung open as he was lost in the ecstasy of having his boy pussy stuffed with over a foot of prime meat.

Jenna took a few steps, jiggling her toy around as she walked. She gave some light thrusts and made him bounce up and down as he dangled. Not content to play like this forever, Jenna then put her arms under his legs. Bending his legs and hooking them under his knees, she grabbed him firmly around the neck. She held him in the full nelson position as she raised him up, allowing most of her cock to come out of his ass.

He was folded up like a pretzel. His body was entirely compliant to her strong muscular form. However she wanted to fuck him, his body would surely accomadate.

Jenna bent down into a squat as she held him on the end of her cock. When she had reached the bottom of her squat, she quickly exploded into the standing position. As she did this, she thrust her hips forward, burying her dick deep into her workout partner.

“One,” She grunted as she drove home her hips. “Two” She dipped down and up again, bottoming out in his colon on every rep.

Seeing her strong and muscled legs, no one would be surprised at her ability to excel at squats. Still the **** with which she was driving upwards was more than a bit impressive.

“Twenty-six, Twenty-seven.” The warm tight feeling of having her entire cock enveloped in a soft wet hole that had been arranged specifically for her use was more than enough motivation to keep up her pace.

“I do a hundred squats every day fuck puppet, so don’t think you’re getting out of this anytime soon.”

The fucking kept up for some time. The veins in Jenna’s legs began to bulge as she strained against the buildup of fatigue.

“Eighty-one, Eighty-two!” Machine like, Jenna kept up her onslaught. Her face was red and sweat dripped down her back. Despite her obvious exertion though, she wasn’t slowing down. In fact, as she approached her goal and her orgasm, she only seemed to speed up.

“Ninety-eight, Ninety-nine. Oh fuck!” She exclaimed. “This is the best workout of my life.”

“One hundred!” As she crested the finish line in more ways than one, she dropped to her knees. Still holding his folded form in her powerful arms, she slammed him down one more time on her pelvis. Her cock stretched the skin of his stomach so that you could see the outline of her head as it protruded out of his abdomen. Thick streams of cum erupted from her dick and his stomach bulged out noticeably.

Her release came out in large spurts. Every time her balls pushed out a new wad, it was possible to follow it as left her pulsing sperm tanks, traveled up her urethra and shot forcefully into his guts. After almost a minute of continuous ejaculation, he was full, and she was spent. Finally, she began to release her grip. His limp, soft body collapsed against her rock hard abs and soft pillowy tits. He had passed out from both lack of oxygen and some of the most overwhelming pleasure he had ever felt.

She put her hand on his stomach. He felt pregnant with the copious liters of seed she had pumped him with from both ends. Finally feeling satisfied, she pushed him gently off of her softening cock and onto the mat.

Splat! His limp, sweaty, cum covered form slapped the ground as he came to lie on the floor. With the plug finally pulled, thick chunky sperm exploded from his thoroughly used up hole, leaving him in a slowly growing pool of ultra fertile girl spunk.

As Jenna stood up, she took a second to straddle his body and squeeze the last drops of her cum from her piss pipe onto his before she hit the showers.
