From Renta!:

Zenya Kitataka is a college student who grew up surrounded by animals (fluffiness). He hasn't been able to touch anything fluffy since he started living alone and spends his days feeling frustrated. One day, he encounters Takeru Nekoya on campus, who has cat ears coming out of his head. Was it perhaps a hallucination caused by the lack of fluffiness in his life...? When he gives in to the temptation and touches the cat ears, Takeru blushes and pushes him down!! He finds himself unable to stop because the rich deep kisses and feelings of ecstasy are just so good...
