Mizuki and I are in a friends-with-benefits relationship, and we're spending time together again today when my friend Mitsuki suddenly joins us, saying she already knows about our arrangement. She's a cute, modern-day J■ who looks just like Mizuki, and now the two of them—both active J■s—join me in a lustful threesome. Filled with desire, we give in completely to our urges. Even my friend, who's technically my girlfriend's friend, reveals her own inner slut.
