[ROYD-339]

My younger sister's resilient tits made me horny, so I immediately squeezed them... I thought she'd reject me, but she kept kneading my dick with her tits as if reluctant to let go, and before I knew it, we'd become secret fuck buddies as siblings. Ruka Itoi

My cute younger stepsister Ruka, who came into my life through my parent's remarriage, has godlike tits that drive my adolescent self crazy. One day I couldn't hold back and made a move, but she rejected me saying "disgusting" and I was crushed. However, the next day, an unexpected turn of events awaited. I caught Ruka alone, masturbating her nipples as if reluctant to let go. "Turns out we were both aware of each other," and with that, we easily crossed the line. Taking advantage of our parents going to a hot spring, before I knew it, we had evolved into secret fuck buddy siblings. During study time, under the dining table, in the bath... a thrilling sex life began, full of the risk of getting caught by our parents. We're not blood-related, so there's no problem, right?
