After Casey finished with aiko, she stared at aiko's huge ass as she walked down the street. She knew that aiko was going to make a sexy Futa family for herself and her own family to enjoy. Casey looked in her purse and found the bottles of semilk, their scent delicious and strong. She also noticed a Jock walking past. "excuse me, sexy...", Erin said, knowing that he wouldn't be able to resist. Erin talked to the jock for a bit, realizing that he was becoming more aroused as time went by. She found out the jocks name (Steven) and brought him to the campus's new milking room. Unbeknownst to Casey, the milking room wasn't visible to regular students until a Futa brought them there. "Mm, Steven, drink this before we start." "uh.. Ok" Steven replied, his horniness getting the best of him as he took the bottle of semilk from Casey. Casey looked at Steven. "yucky, disgusting men... " she thought, looking over his 6 foot tall frame, brown hair, and blue eyes. As he finished the bottle, he felt both pleasure and pain as his body became that of an attattractive futa's. His 6 inch cock grew to ten inches, and below that, a vagina formed. He shrank from 6 feet tall to a measly 5 foot 4. He, now she, felt her hips widen and ass expand massively, growing nearly twice as big as Casey's. Massive O Cup breasts grew from her now tiny chest as her waist became impossibly thin. The breasts were incredibly perky but soft, and were completely natural. They weren't even too heavy for Steven, now Stephanie, to handle as they filled with milk. Stephanie's hair grew past her hips, and became a bright platinum blonde. Her skin tanned across her curvy body, while her face became small and petite, as a heavy permanent layer of makeup appeared, and her lips became massive stereotypical cocksuckers. Casey felt her erection grow, as she stared at the beautiful bimbo. "one less man, one more happy bimbo Futa!" she thought happily. Meanwhile, Stephanie was feeling her mental changes happen. "I'm, like, totally a happy slut! I love futas! Men are like, totally disgusting!" New memories of being Stephanie, and a happy obedience for Erin appeared. As her changes finished, she and Casey climbed into a tub in the milking room, jerking each other's naked bodies off and making out. Both leaned back to opposite sides of the tub while they were pleasured, and both came at the same time, though Stephanie came much more. As Stephanie got dressed, Casey noticed and admired the short skirt and bright pink tube top, which matched Stephanie's underwear. "Like, you were totally a great fuck! I'm super happy I'm moving in with you and Erin, teepee!", Stephanie said as she left. "Mm, that was great. I can make lots of futas with this... " Casey said, grabbing several of the milking bottles, pleased that she turned a disgusting jock into a beautiful bimbo.
