My wife and I were at a swingers club and the theme that night was “anything anywhere “ so there are relaxed rules. My wife loves to dance and me not so much - self conscious so drink a few too many to relax. I left for the restroom and returned after 5 minutes or so…spot her on the elevated dance floor with a guy behind her and his arm across her chest pulling her in. She swaying and dancing and staring at me which I then slowed my walk to see this play out. I get up to her and she says “this one is hard” as can feel his hands on her as I reach for her waist. Who know where else his hands where under her dress but could tell they were under by the look in her eyes and expressions. He had his cock out and she knelt down on the dance floor starts giving him head. After a minute she comes up and facing me again….I said why don’t head over to the couches ? Instead she moved to the side of the dance floor that had high bar seats, sits down and pulls up her dress. I look down and this guy already has his condom on and solid 8-9 inches of black hardness. Before I had a clue what was going down she pulls her panties to the side and he’s sliding in. I am just standing there mesmerized of what was going down with people all around us. He’s working away and between the visuals and moans just feel my cock pulsating without touching it. Like oh shit I am cumming hard in my pants totally cucked. After they were done..her pussy was so plumped and said it ached it was so full.
