Nanjiware O Koryakuseyo (Official)

Masashi is an erotic game maniac. Today he starts playing games as usual. But when he comes back to his room with a roll of toilet paper, he finds the beautiful Prince Suquarthur standing in front of the PC screen as if he just popped out from the game. The prince of Isekai with horns and a tail asks Masashi, "You, the legendary human… Take me for yourself." Why does the prince come here at all? And what is his purpose? Are they destined to marry or what?
