I really don't know if this should be considered Yaoi, tbh. It felt a lot closer to futanari x male, rather than male x male. from the body porportions to the face, seemed 100% female to me besides a bulge, like something aimed at the moe ecchi crowd rather than fujoshi. ( ̄へ ̄)
Meh, not so fond of this one - but that is just my opinion
