i would tie him up put a bag over his head and tie if off. I would give him a little head and play with his hot white socked feet until his body shuttered and stopped moving. I would then fuck him and cum in his mouth then dump his body somewhere after cutting off his feet and dick as a reward.
The thing to do is fuck him, then put the bag around his head while sucking him off. When he cums during his death throws, the mouthfuls will be welcome.
