Nozomi Aimura - He Was Prepared To End Their Relationship, part 2

As a virgin, I couldn't resist and touched my dick to my sister who was showing me her unprotected panties. I was prepared to lose my place in the household for being seen in such a moment, but my sister showed me her pants as much as she could. She was so excited that she started masturbating in front of me, and for the first time I heard my sister's sad gasp. Then she crossed a line she shouldn't have crossed. She took away all the things that made me feel good, like sucking, tit-fucking, and sex.
