[MKON-029] Because of me, my sister made her classmates touch her thighs.

When my classmates knew I had an older sister, they came pressing me to let her touch that muccimuchi thigh of your sister's thigh, and they forced me to make that promise. When I told her about it with the intention of being disliked by my favorite sister, she said, "It's OK." Is it good!? Why don't you let the strangers who are younger than you touch your thighs freely? There's no good reason! To be honest, I thought she would refuse, but I was a little disappointed that my sister's idea of chastity was unexpected.
