Can I Taste You? -This Young Buff Wants Me-

Asahina is a regular employee who gets dumped by his girlfriend who, it turns out, had been dating three guys at once. Along with Asahina, Sota also gets dumped and they drown their sorrows in alcohol together. But, before they know it, they end up in a hotel and Asahina finds Sota on all fours above him.
It starts with Sota saying he likes guys, too, and then before he knows it, Asahina finds himself enjoying things more than he ever thought he would.
