I Was Reincarnated as a Mr. Steal Your Girl in an E*oge, and I Had Already Embraced One of the Heroines…

“Wait… I’ve already slept with a heroine?! Seriously, am I really the real protagonist?!” I woke up to find a naked woman lying next to me. When I saw her face, I realized… I’ve been reincarnated in an eroge! And the woman next to me was one of the game’s heroines. For the sake of the heroines’ happiness, what should I even do? And why is the protagonist so pathetic?! The protagonist is supposed to protect the heroines, but he’s just so spineless. His useless pride just ends up hurting the heroines… If that’s the case, then I’ll… I’ll take the heroines for myself! Note: There might be scenes where you think, “That’s way too unrealistic,” but hey, it’s the world of an eroge. What do you expect?
