3DSVR-1599 - [VR][8K] "I, the younger brother who likes my sister with glasses, am mistaken for her boyfriend during a home date and caught in an affair sex" Sumi Suehiro

I live with my father, mother, sister, and me, a family of four. I have a secret. It's that I like my sister. She's kind and cute. My favorite point is Glasses . My eyesight is so bad that I can't recognize people's faces without glasses, and her timid appearance is also cute, but when she puts on glasses, she becomes even cuter, and I spend my days happily. One day, my father and mother are away, and I finally get to be alone with my sister! I thought, but my sister brought her boyfriend, Makoto…. Moreover, despite me being there, they're on a home date and seem about to merge. I absolutely won't allow this. I won't give my sister to anyone else! Just as I was thinking that, luck came my way. While my sister was showering, Makoto had an urgent matter and had to leave…. I didn't tell my sister about this and lied, pretending to be Makoto and went to her room. And I became one with my sister….
