DASS-546 I was about to have sex with a big-breasted older sister who would go along with it if pushed, but my bad friend always interferes, and I can't have sex. Kana Morizawa.

Kana is the older sister who lives next to my room, and we've been close since we were little. Lately, she's been taking time out of her schedule to come teach me, and every time I get flustered by her uniquely sweet adult scent. No more! I can't hold back anymore! I mustered up the courage to force a kiss, but just before that, my shitty friend Hiyamori barged into the room and ruined the moment… Ah, if only it had been a little longer… As I'm left alone to stew in frustration, behind the scenes, my shitty friend is using his characteristic shamelessness to have his way with her, fucking her pussy as much as he wants...
