"Jeremy, I want to be your foot." said Ryan.
"Fine." said Jeremy.
The two brothers ran upstairs to their room and locked the door. Ryan and Jeremy took off their clothes and threw them off to the side.
Ryan bent over, concentrated, and touched Jeremy's right foot. Both boys felt the familiar tingling sensation as well as sexual pleasure.
Jeremy's foot seemed to suck into his body, leaving a stump of Jeremy's leg behind. Without thinking, Jeremy raised his leg up. Ryan fell onto the ground and stuck his butt in the air. Jeremy watched as Ryan's butt smoothed over, and Jeremy placed his leg on Jeremy's former ass. Suddenly, their two bodies became one, with Ryan attached to Jeremy's leg by his buttocks.
Groaning with pleasure, Ryan felt himself shrink, until he was 4 times smaller than he was before. Ryan rolled his eyes back into his head as his eyelids vanished and his facial features disappeared. Both boys groaned with pleasure as Jeremy's blood began to circulate through Ryan's changing form.
Ryan's hair sucked into his body, as did all other hair on his transforming body. Ryan stuck his arms out in front of him. With inhuman flexibility, Ryan's legs stuck out, cracking Ryan's bones, although neither boy felt any pain, just more pleasure.
Ryan's buttocks suddenly stretched to the floor, obliterating the top half of Ryan's legs, and forming Jeremy's heel. Ryan's torso cracked and contorted, growing and expanding with muscle. Ryan's head moved to the left of his torso. His arms followed, and his legs did the same. Then, Ryan's legs combined into one appendage. Ryan's arms and leg shrunk, until they were the size of toes. The boys wondered what was going to be Jeremy's fifth toe, when their question was answered.
Both Ryan and Jeremy groaned with immense pleasure as Ryan's penis stretched out from what had been Ryan's crotch, eventually moving to the spot for Jeremy's smallest toe. Ryan's arms thickened and condensed. Ryan's fingers became one appendage, which hardened to become a toenail. Ryan's other arm did the same.
Ryan's leg shortened like his arms had, with Ryan's foot hardening to become a toenail. Ryan and Jeremy groaned with pleasure again as Ryan's penis thickened, curled and settled as one of Jeremy's toes.
Ryan's head suddenly widened and expanded, growing bigger than any of Jeremy's other toes. His head thickened and curled. It stretched, forming joints in it. Ryan had become Jeremy's foot. Both boys groaned with sexual euphoria.
