As the world outside grinds to a halt, so does this couple's self-control. They invite another duo into their home, the four of them exchanging hungry glances beneath their masks. The girlfriends strip each other, their boyfriends' erections tenting their pants. The men take turns fucking the other's girlfriend, their moans echoing through the empty house. The women trade places, riding each other's men reverse cowgirl while their partners watch, jerking off, before they all collapse in a sweaty, satisfied heap.
