Chelsea's fun time

Chelsea sighed as she went to the living room with a cock hanging from her crotch, she loved the idea of having one on her, and though she grew one several times before, something about seeing the twins with their delicious dicks just flipped a switch in her head. Pressing her fingers onto her dick, she shivered at the possibilities as she stroked it. Before now, she was always a bit embarrassed growing a dick and hid in her room, staying there until it vanished.

"God, I love this feeling," she sighed began to stroke it, savouring the heft and the heat. Closing her eyes, she bit her lip as she snaked her fingers to her slit, touching and fingering it while she jerked her dick. All the electric pleasure that surged through her was too much and cum a little pre-maturely.

Though she basked in the heat of the cum she spilled on her belly, something flickered in her head and thought of making this more permanent, thanks to her research on futas the other day before. She stood and walked to the kitchen, where she hoped Morgan would be and hoped that she would help her out, or maybe Annie still immobilised by her massive dick. But when she arrived, they were both gone.

With a huff, Chelsea felt her dick throb again as she swung about and stormed upstairs. She barely noticed the twins outside mom's room, or the sounds coming out of it. To her room, she flung the door open, groaned as she saw that Morgan wasn't there.

Then she heard grunts and huffs coming from Amy's room.

Chelsea peeked through the door and found the glorious sight of her muscle-girl sister lifting weights far greater than she usually did, while her cock was a raging tower.

"Yes, yes, yes," Amy huffed as she lifted the weights with her massive strength that was further increased by her temporary futa enhancement. "Faster, better, stronger!"

Chelsea knew that her sister worked out a lot, mostly for her MMA fights that she participated in and made top five in the national women's league last year; she bulked up and became even more avid in her training since then, eager for the upcoming national tournament. She admired her sister for it, to have such a drive to want to improve and get better, stronger than she was the day before. Amy didn't have much friends, strangely, and never went out to the gym to workout, but did to train martial arts, it was odd.

"There!" Amy put the weights done and sat up, sweating and wiping her brow.

Chelsea's eyes grew wide and her dick bouncing with greater hardness when she saw her strong sister strip out of all her clothes and sit back on the bench naked. She saw one hand reach down and under her balls, and heard her sister pant as the wrist moved about; she kept on going up until her whole body shivered, legs squeezed around her hand as she bent forward and moaned.

"Fuck..." Amy said gulping in air as she closed her eyes.

"That's why you don't go to the gym," Chelsea blurted out from behind the door.

"What?" Amy's face turned beet red. "Who's there?"

Chelsea took little time to come through the door, closing it behind her.

"Chels?" Amy blinked. "What are you doing?"

"You get horny when you workout, don't you?" Chelsea rush forward to stick her face directly in Amy's face. "Don't you?"

"What? No I don't," Amy was flustered and tongue-tied at being caught. "I mean--"

"Shhh," Chelsea put a finger to her sister's lips. "It's fine, I get horny at the thought of dickgirls and futas!"

Amy gulped, unsure how to respond.

"You love having futa strength, don't you?"

Amy gave a sheepish nod.

"Why not keep it?" Chelsea said as she slid onto her sister's lap, dicks rubbing together. "I'm sure it would be fun."

"But then I'd have to enter the futa league," Amy tried to frown and sound confident, only with this rubbing against her, she was hardly able to concentrate and stumbled all over her words instead. "That would... uh... be a lot of paper work and stuff."

"You know..." Chelsea hummed as she squeezed her muscly sister's arms, feeling the strong back and powerful thighs. "I could help you with that?"

"Really?" Amy gulped.

"Yeah, really," Chelsea nodded. "But I want you to help me first."

"Okay," Amy mumbled. "What is it?"

"Help me..." Chelsea quickly shoved her sister down to the bench and lifted the balls. She pressed her dick inside the soaked and sweaty snatch, and heard a needy moan. She then traced her hand on Amy's abs, enjoying the definition and the feel of sweat. "...help you."

Amy was grasping for breath at having a dick inside her for the first time since her last boyfriend some years ago. Yet unlike her ex, Chelsea was a bit thicker, and the dick belonged to her sister. It was all too much for her head, and already she felt out of breath.

"Holy fuck you're tight," Chelsea winced. "I guess its because you work out so much."

A grunt was all Amy could muster.

"Well here we go," Chelsea began to push deeper, feeling the almost vice-like grip the pussy had on her. It almost hurt to fuck the hole, yet the pleasure was just too out of her world to stop, so she just kept on going, pumping the muscly girl with all the energy she had.

Amy's tongue lolled out of her mouth as she felt her insides being rearranged.

It didn't take long for Chelsea to explode in her sister and become a natural futa, just like the twins. She was elated at that, knowing that she now enjoyed exactly what they did. She thought that she might sign up for a futa only hook-up site, enjoy a few dick in her and enjoy her dick in others; she even thought of the videos she fingerbanged herself to this morning, and licked her lips at the idea of her being in them, getting fucked and fucking with her new dick.

"Shit," Amy groaned. "Why does it feel so warm?"

Chelsea being snapped back to reality, started having creampie sex with Amy, cumming a few more times before she became soft. Glad that Amy was still hard, despite her exhaustion, she straddled the muscle girl and slammed down on Amy, feeling her vulva part with the delicious dick you craved.

"No...!" Amy whimpered at the new sensation, chest heaving, her eyes wandering and unfocused. "Stop."

Chelsea ignored her sister and went wild riding the swole dick, grinding and doing all the work for her sister. It didn't take long for her to be filled, and even then she didn't stop, her need insatiable, using her sister as if she were just some dildo. It was a mind melting pleasure as she kept fucking herself on it, over and over, filled more and more, stomach fluttering and purring with the constant filling of futa creaminess.

The mid-morning eventually became sunset, when Chelsea finally collapsed on top of her muscly sister, both of them newly minted futas, strong and with nice dicks.

"That was the best," Chelsea kissed her kissed on the cheek, though Amy seemed to exhausted to reply, falling asleep only seconds after her sister stopped.

Morgan sighed as her mom snuggled up to her on the bed."How did I get this far out of it?" she grumbled as she stared at her new cock, a natural futa now just like the twins. She looked to her Martha's crotch and found that her dick on the other hand, disappeared. So intent to dump several loads into milf pussy, her horny brain took over and she didn't think about anything, now she had to deal with the consequences of it: being a futa forever.

Martha sighed, pressing her breasts further onto Morgan, a blissful happiness in her features.

"Right, that too," Morgan groaned, noticing how Martha clung to her daughter, not as a mother does a child, but as a woman does for her lover. In that horny brain moment, she seduced her mom with her massive dick, and in front of a massive audience online too, meaning there was little to comeback from, even if she tried. Since she was also such a massive hit amongst chat as 'Momma's Bull,' the donations flying every second, it was hard to pull away from that too, especially ones asking for her cum.

"Morgan..." Martha made an amorous sigh, nuzzling more into her daughter's arm. "You felt so good..."

Morgan huffed and held her mom tight and dozed, glad that her mom was at least happy.
