[Chinese]ROYD-339 I couldn't help but grope my stepsister's bouncy tits, which were a bit uneven… I thought she'd reject me, but then she was kneading her own breasts like she didn't want to let go. Before I knew it, we had become secret fuck buddies. Ruka Itoi

Ruka, my adorable stepsister from my parent's remarriage, has tits that drive me crazy in puberty! One day I couldn't hold back and reached out, but she rejected me saying 'That's disgusting'... But the next day, an unexpected development! Caught Ruka doing solo nipple play, looking reluctant to stop! Turns out we were both aware of each other, so we easily crossed the line! With our parents gone to the hot springs, before we knew it, we'd evolved into secret fuck buddy siblings! While studying, under the dining table, in the bath… I started a thrilling sex life without my parents finding out! It's fine, right? We're not blood-related.
