MOC-051 My little sister, who mocks me for being a virgin and provokes me with her dick, gets counterattacked with in-vagina ejaculation. Shiraima Reo

One day, I found out that I was a virgin at school, and I came home depressed after being ridiculed. Then my cute little sister came over and threw a terrible word at me. “Hey, hey, Onii-chan… are you a virgin??” ! I was so shocked that I thought I would masturbate and fall asleep, but the next moment, her sister said something unbelievable again. “… Shall I let you graduate from virginity?” After that, I was completely swayed by her sister.
