MKON-025 — I'm So Sorry... I Was F** By My Classmate To Promise That I'd Let Her Touch My Sister's Breasts. Sachiko

I promised my friend to touch my sister's breasts... When I told my sister about it, she said, "...it's okay." To be honest, I thought she would refuse, and I was shocked that my sister had no sense of chastity. Because there's no way she's letting a stranger touch her breasts! I didn't have any signs of a boyfriend until now, so maybe she was actually a bitch. And so the guys from her class came over to our house. From now on, my sister will have her breasts touched...
