HUNTA-664 Brother, are you avoiding me? It's the opposite, stupid! What a strike! (*Inner voice) 3 My younger sister, who innocently approaches me...

My younger sister, who is always innocent and loves me, is actually in trouble because she is extremely aggressive as a member of the opposite sex! Anyway, when I was avoiding her so that she wouldn't find out, my sister mistakenly thought that she hated me, and in order to get closer to her, she barged into the bathroom, saying she would wash my back! I got an erection from the feeling of my sister's swollen breasts and skin rubbing against each other, and I thought she would hate me, but I was intrigued by the fact that she got an erection for me.
