I lost to my brother at cards and got new semen in my undies

In this steamy XXX video, a brother and sister are playing cards and the stakes are high. The brother wins, and as a forfeit the sister has to take off all her clothes and put on a pair of tight panties. The brother then teases her body, making her incredibly aroused and frustrated at the same time. As punishment for her loss, he takes out a tube of his own semen and rubs it all over her panties, making sure that every inch is thoroughly covered. She is left with a wet, sticky feeling between her legs, and a burning desire for more.
