You slowly stop sucking the cock and give the slightly disappointed man a quick french kiss before standing up and moving to the man being fucked. Having still not cum, your cock is rock hard. You open up your trousers and show him your prick, which he grabs and begins to masturbate. All the while you can't help but watch the man pistoning into his butt. You feel a tug on your cock and the man moves you around so he can suck your cock - unbidden your hips begin to thrust your cock into his waiting warm mouth. Watching the man at the back, you quickly establish a rythem and soon you can feel your cock swelling before exploding into the man's mouth. He swallows your cum just before the man still working his ass grabs his hips and gives an almighty thrust before leaning heavily against his back. After a second of rest, he pulls out and you notice he wasn't wearing a condom. You move around to the back of the man and see cum dribbling slowly out of his ass.
