My niece has grown up a little and become horny, and now she's a bit of a precocious brat who wants to play dangerous games! She got so excited by porn magazines and erect cocks that she said, "Put your hard cock in through my pants! If you do it through my pants, it's not sex, right?!" I twisted my erect cock through her cotton panties, with the crack clearly visible, but this was practically sex! When she said, "I can't hold back! Put it in for real!" I couldn't hold back and ended up having creampie sex with my niece!
