I’m in the guest room listening for her to ring the bell for service. I’ve heard them fucking on and off for an hour or so. He fucked her for a half an hour first, as I listened intently from the other side of the wall. I can tell by the sound what position they’re doing sometimes. In doggy style she grunts and gasps, but in missionary she moans deep and loud. I picture her with legs wrapped around his torso, welcoming his thrusts, deep into her pussy, wantonly, lustfully. She came twice already. Then he came with loud grunts of determination. After a quiet period, when I was expecting to be summoned, they started up again.
