I live with my sister who is a company employee. As soon as she gets home, she takes off her suit and becomes lazy in black pantyhose. Actually, I secretly get excited by seeing my sister's underwear and ass, but my careless sister doesn't notice at all. One day, perhaps due to fatigue, she falls asleep without wearing any panties under her pantyhose. Seeing this, I can't hold back and assault her, but surprisingly, she doesn't seem to mind… In fact, she starts using my dick to release her pent-up sexual desires that have built up over the years of not having a boyfriend.
