Puchitto Hajiketa,

Synopsis

Ashitaka's an out and proud gay man, trawling for booty calls at his favorite gay bar—but only bottoms need apply, because Ashitaka only tops! His first attempt at gay sex three years ago ended painfully and embarrassingly, and he vowed to never yield his ass to another man again—but fate has decided to throw the very man responsible for his 'bottom trauma' back into his life, and the guy's looking for a fresh start.
