Current favourite fantasy is catching my wife with her boss. She's on her back, legs spread wide. I see her wetness before he's even begun to slide in. He rubs his cock over her clit until her juices are rolling down to her ass. She cums. He then slides fully into her, she moans as he does. Their bodies slap together with every thrust, and she whispers to him to screw her harder. Her toes curl as she cums again, her big tits bouncing with every thrust. He asks to cum inside her, she says 'thats not a good idea, its a risky time'....and with that he explodes, streams of cum fire into her. She masturbates herself to cum again. I make them aware of my presence. Saying nothing, i pull my hard cock out and slide it into her slimey creampie. I cum instantly. They laugh at me. They then make me watch their second round. Before he cums, he pulls out of her, gets me on my knees and makes me stroke myself while he cums on my face.
Maybe hook up with a celebrity couple (Zoe K and Channing T, you listening?) or have really wild dirty sex with 2 guys in front of a bunch of people, like at a party.
