Nonke Ryman no Ore desu ga Maiban Himo ni Aegasaretemasu

Office worker Naoto was saved from getting run over by a mysterious handsome guy, Taiju. However, because he had kept him company at the hospital, Taiju loses his home! Feeling guilty, Naoto invites him to his home, and repeatedly apologizes to him while drunk. Then Taiju drills his hot tongue in, saying that this was his job! Enjoying the sex with a guy he just met is definitely strange... but when he's the one doing me... I can't retaliate...!
