In the heat of the moment, my wife, dressed in a seductive black lace nightie, invites our friend over for a late-night drink. As the night progresses, their chemistry becomes undeniable. I'm hidden, watching as they start to kiss, their hands exploring each other's bodies. My wife's moans fill the room as our friend fingers her, her nipples hardening. They strip each other, their bodies pressed together, before our friend slides his hard cock into her waiting pussy. I can't help but stroke myself as I watch them fuck passionately, my wife riding him reverse cowgirl, her ass bouncing with each thrust.
