Bratty MILF - Spencer Scott

Spencer Scott and her stepson Jason have checked into a hotel. Although Spencer promised Jason there would be two beds, the only rooms available were single kings. Jason offers to sleep on the couch, but Spencer tells him not to be silly.
Spencer goes to the bathroom to freshen up. She's totally naked and rubbing lotion onto her skin when Jason knocks. He's shocked when he sees Spencer naked, but she assures him that it's fine. Later, when they've crawled into bed together, Jason waits until he thinks Spencer is asleep and starts beating the meat. Spencer realizes what's up and then decides to help Jason out as long as he swears he'll never tell...
