Heather realizes she is better off not resisting herself

Heather sat in her room, surrounded by cum from her own dick and others'. The memory of orgasm sat in the back of her mind, tempting her with its raw power, the thought of cumming again lighting her desire anew. She had resisted her desire so far, but it hadn't done any good. She had already transformed her cousin, her MILF neighbor, and, if what Monica said was true, another woman. She couldn't deny that it had felt incredible and watching Monica and Jenny change had been hot as fuck. She wanted to see it again, she realized.

"I want to turn more girls into futas," she said quietly. As if rewarding her for the thought, her dick jumped, leaking precum out of the bulbous tip. Her arousal spiked again, her balls churning with fresh semen, but she held back. She could masturbate then and there, but why bother with that when she could use someone else to get off? And she had the perfect person in mind.

Heather peeked out of her room, looking around for anyone in the hallway. No one was there, though she could hear faint moans echoing from somewhere else in the bunker. Seemed like she wasn't the only one who had decided to embrace her desires. She didn't waste any more time. Satisfied the coast was clear (for all that it mattered), she ran down the hall towards her destination.

Within two minutes, she was barging into her friend Mandy's room. She heard a yelp as she closed and locked the door. She turned, her full futa glory clear for her friend to see. A friend, Heather was delighted to see, that was only wearing a towel.

"Thighs..." she mumbled, eyes fixed on Mandy's upper legs. Her friend had the best, most delicious legs she had ever seen, at least before she started turning people into sexpots. Her breasts were also fantastic, large and heavy on her chest. The woman had been blessed during puberty, all of her growth going to her tits and thighs.

"H-heather? What happened to you?" Mandy asked, realizing who was in front of her. Heather also came back to herself a little, finally looking Mandy in the face. Her long time friend had dyed her hair pink a few days before everything went to hell, just the latest color in a long streak that hadn't been broken since they started high school.

"I need your help," Heather said, her eyes drinking in her friend's ample figure beneath her towel. She was already imagining what she would look like with a hefty dick dangling between those plump legs.

"Does it have anything to do with that thing?" Mandy asked, on the verge of panic at the sight of Heather's huge breasts, not to mention her clearly real, twitching, erect cock.

"Yeah, but it's going to be okay, I promise. Will you help me? Please?" Mandy stared a minute longer, extremely hesitant, but finally nodded. "Okay, would you turn around for me?" Mandy complied, one hand still holding her towel shut. She heard Heather walk up behind her, but was surprised and dumbfounded when the cloth she was holding up was torn away, leaving her entirely naked. She didn't have a chance to protest before Heather's hands roughly gripped her large tits.

"Ahhhnnnhh~" she cried at the sudden feeling. A second later, she felt something long, thick, and hot slide between her legs. "Heather, what-"

"Shhh, just let it happen. Oh, you feel so good, I knew these thighs were to die for. You won't die though, you'll be just like me. Fuck, I wanna cum already. You don't mind, do you?" Mandy couldn't answer, she was too overwhelmed by the knowledge that her friend was spraying cum all over her pussy, the head of her fem cock, squeezed between the pink haired woman's thighs.

"You ready for it?" Heather asked, feeling Mandy's heart rate pick up. She could also feel the muscles in her friend's thighs quivering, her pussy fluttering, and the boobs she was holding so tightly slowly, ever so slowly, start to grow. "You can feel it, can't you? I fought it, but you don't have to. Just let it happen. You can't stop it anyways." Heather felt Mandy's tits swell sharply, rapidly outgrowing her previous size until they overflowed from her hands. Still, she didn't let up, sinking her fingers deep into the tender flesh and drawing a scream from Mandy. It was music to her ears, and her dick fired again, encouraged by the gush of juices from the woman's pussy.

"Ohhh, yessssss....that's so much better. Fuuuck...." Heather moaned, finally able to empty her balls with relish and without fear. She knew what she was, knew what she would turn Mandy into, and she enjoyed it. The thought only redoubled when she felt a telltale bulge pressing against her cock and something began leaking from Mandy's huge tits.

"You're lactating? Mmmm, I wish I could have sexy, milky titties. Guess I'll just have to enjoy yours then," the futa said, spraying more semen around. The pleasure she was feeling from Mandy's thighs only increased as they became perfect and sexy. She was tempted to stick her dick inside the pink haired girl, but was foiled when a sexy dick rubbed against her own as it sprouted and grew. Mandy was grunting wildly as milk flowed from her tits in greater and greater volumes and her new shaft spurted its first traces of semen.

"Can I have a taste of this?" Heather asked, not waiting for an answer as she lifted an enormous tit and sprayed its white fluid into her mouth. The taste was divine and instantly made Heather want more, but she resisted in favor of grasping Mandy's new dick firmly and jerking her off quickly. Unprepared for the cascade of new feelings, Mandy thrashed in ecstasy, spraying as much cum as she could out of the new penis. Even once she ran out of cum, her body kept convulsing until her balls began pumping out more thick fluid, which was promptly fired in every direction.

"Guess I don't have to worry about you fighting it," Heather mused as her long-time friend collapsed to the floor, writhing in a pool of their combined juices and milk. Heather knew she'd recover soon enough (probably), but didn't want to wait that long. She intended to make up for lost time in corrupting the rest of the bunker and wasn't going to wait around for Mandy to come down from her high. Instead, she decided to leave her to her own devices, knowing they'd run into each other again eventually. She quickly left the room and, with one last look at her orgasmic friend, went off in search of untransformed people.
