When I heard Demi Hawks VR diamond stretching, I couldn’t resist the temptation of spying on her. She looked so hot and sexy in her tight outfit when doing her stretching exercises, that my dick got hard. I know she is my Stepsister, and we are supposed to be in friendly relations, but it’s impossible to stay calm when such a hottie bends down and you see her round ass. Sure, I started jerking off, and that gave my position away. Demi Hawks grabbed my hand, told me to sit down next to her in a lotus position, and told me I could watch but not jerk off because it was wrong. I tried hard to keep within the bounds of decency, but I failed. Even a statue would get excited when Demi Hawks would arch her back and show her ass, and I’m not made of stone, so I jerked off again. Finally, Demi Hawks got interested in what I was doing and started rubbing my dick as well. Then she Deepthroated my dick to prove her throat was stretched enough. It was impossible to stop me at that point. I ripped her yoga pants and checked her pussy. Demi Hawks held her legs to help me open her sweet hole as wide as it was possible.
