"Y'know, I'd love to tap you." Thea said with a coquettish tone. She rubbed her chest as her tiny breasts flattened out completely. Her tomboyish hands became dainty, and thin. Her stomach became toned as she grew a bubble butt and shapely legs. Her lips plumped up and makeup coated her face. Ginger hair turned a solid red as it lengthened until it reached her butt. Her freckles increased in number until her skin was swarmed with them.
"Then why are you over there?" Sonja licked her lips as they plumped and her face was done up like Thea's. Her once bountiful chest shrunk away as her buttox compensated by growing larger than it already was, accompanied by her new large birthing hips. Already relatively feminine Sonja became more feminine as her skin turned pure white and her hair turned solid black and grew until it reached the backs of her knees.
The two were nearly complete, but there was one last thing.
Both of them felt growing bulges in their panties. Larger and larger. The girls turned fembois moaned as they stripped down until they were entirely nude. Between their legs were fully formed ten inch penises with accompanying sacks. Pink precum practically poured out of each of their members.
"Oh, God. Just fuck me!" Sonja turned around, bent over, and spread his cheeks for Thea who didn't hesitate to plunge inside his new boyfriend.
Thrust after thrust made both fembois moan out. It didn't take long for them both to cum, but they didn't stop. No, it actually encouraged them to go again. They wanted more pleasure. Like machine gun fire, they kept going repeatedly. They began switching up positions, trying every style they could conceive. Frotting, blow jobs, thigh sex, and anything else they could think of. Lust was what dominated their minds.
A salty smell that could never be removed had sunk into the room which began to change. As bits of their cum got on objects in the room, they changed. The girly room became so effeminate and pink that it seemed like a parody of what a girl's room was supposed to look like and was stocked with plenty of new outfits for the couple.
As the lovers finally rested, they heard Sonja's mother call them for dinner, and both of them felt hungry.
