I'd untie you eventually, after I've shot a couple of fat loads on you, wiped all that spent cum up with my fingers and fed it you. Would possibly have to finger your holes too and feed you that as well.
I'll do a stepdad where you wind me up flashing your bits, so I lose control and face fuck you. Pulling your hair until you deepthroat me properly, licking my balls at same time. Until i cum over your glasses and make you lick it off while I spank your arse and finger both holes.
