Sarah laid in the tent full of spunk while Michelle and Heather closed the tent up. Sarah was panting, unable to move. She felt like she had a fever. All the while she kept shoving her fingers in her needy cunt. Heather pushed Sarah on her back while Sarah fingered herself, unable to defend herself. The spunk's feeling and scent were clouding her mind and making her even hornier. Michelle pushed her huge cock into Sarah's mouth, while Sarah felt an urge to suck it. While this was happening, Heather stuck her cock into Sarah's ass. Sarah's breasts had continued to grow with her ass, thighs, and hips getting plumper as well. Michelle and Heather began fucking Sarah as her breasts and ass grew and grew. Sarah was in heaven as this happened, fingering herself at the same time. Sarah's ass grew to the size of two volleyballs, while her breasts grew even bigger than Heather's as they became huge L cups, compared to Michelle's G cups and Heather's J cups. As the trio fucked, subtle differences happened to all of them. Flaws disappeared from their skin. Each girl's faces now looked like they had heavy, slutty makeup on, though it was permanent. Their lips plumped up dramatically, becoming cock sucking lips. Michelle's grew the biggest as her face became the sluttiest. Michelle's hair also lightened to a honey blonde while Heather's black hair and Sarah's red hair stayed the same. Body hair disappeared as the hair on their heads became thicker and sexier. None of the girls noticed, however. Sarah finally orgasmed for the last time from her pussy, her whole body quivering as she continued sucking on Michelle's cock and getting ass fucked by Heather. Quickly, a 10 inch cock replaced her vagina, with egg sized testicles growing in. All three girls suddenly came at the same time. Sarah happily swallowed Michelle's cum, while her giant cock sprayed cum all over the tent, mixing with Heather's and Michelle's. Heather came in Sarah's ass, filling it with warm spunk. Sarah laid on the ground, smiling while she recovered from the orgasms. Just like the other girls', her mind had adjusted. She loved her new shemale body. She got up and pressed her plump, soft lips against Heather's, turning it into a passionate French kiss. Breaking it, she said. "Thank you girls for making me so sexy!" Sarah was finally happy. Sarah wanted to cum on girls and to be covered in thick, sticky spunk. She and the other girls felt that they had a duty to bring people into the river...
