Our parents are not at home and we are stuck in quarantine with my step brother. While I am camming, he comes into my door without knocking and catches me half naked getting strangers off. He threatens me with telling my parents so I make a deal with the devil. I tell him he can stay and watch but he should behave, so no touching. The idea of him watching me fuck my pussy in front of strangers gets me so wet already. My wet panties confirm that. I rub my clit, finger my pussy, play with my tits in front of him and guests in my cam room. I even zoom into my pussy and show how wet I am. Damn his cock is so big like how I always imagined. I make my brother cum first giving him a countdown in the end. it. After he cums, with the request of one of my guests in the chat room, I turn around, show my beautiful ass and give another cum countdown to make my guests cum in doggy position. It feels so good to be watched by my brother and others behind the PC monitor!
