I Need Money for My Muscles

Ryuta Ono is a college student who loves working out, but is always short on cash.
Maintaining his muscles requires money for food, protein powder, as well as other things.
Over lunch in the cafeteria one day, his friend, Fumiya Yoshikawa, gives him a suggestion.
He suggests Ryuta sell his body.

"My body, huh...? Someone like you could probably make money that way... There's no demand for a sweaty gymbro type like me..."

"Sure there is."

"Then hook me up. You know someone into that?"

Fumiya points to himself.

"...What?"

For the first time, Ryuta realizes that his guy friend has been sexually interested in him.
He's confused, but only thinking about the money, he agrees.

He gets jerked off while kissing, cums from a masturbator he already used, has Fumiya cum in his mouth, is made to give himself an enema with the showerhead while being watched, gets his ass fondled, and then he gets his ass drilled...

He has no idea what he's about to go through...
