Use your breasts to clean Tommy's cock

You look up at Tommy, the water from the shower running down your face and forcing you to blink repeatedly. He seems uncertain of how to respond, but a very naughty idea enters your head.

"I know!" You exclaim, and bounce to your feet, your tits jiggling.

You grab the bottle of body gel. You open the cap and lift it up to the level of your face and then let Tommy watch as the goopy soap streams out onto your tits. You keep one arm under them to hold them together and keep the body gel from sliding down your tummy. When you've got more than enough deposited in the valley between your big tits you replace the body gel on the shelf.

You use both hands to rub your tits up and down, giving Tommy a good view, until the body gel creates a foamy lining for the canal formed between your tits. You then sink to your knees in front of Tommy and his big dick.

"I'll just have to scrub this nice and good," you remark.

With one hand cradling your tits together you use the other to grip the shaft of his prick and guide it into your cleavage. It slides in easily on the track of foaming gel and you let go and apply pressure on your tits from both sides. Tommy groans at the sensation of his cock being crushed between your soft titflesh.

"Ooh, yeah," you laugh, "this should clean it up real nice."

You begin to bounce up and down a little, his cock sliding in and out of your lubricated cleavage. It's so big that each time you lower yourself the head and a couple inches of shaft poke out and proud your throat. Tommy quickly catches onto the rhythm and makes your job easier by thrusting his cock for you.

As he fucks your tits you lower your chin, part your lips, and extend your tongue to tease and lick the head of his cock each time it spears through your cleavage. Each time Tommy thrusts his big prick through the valley of your breasts his hips and balls slap against you with a wet smack.

The angle is a little awkward, but Tommy bends his knees enough to get a perfect glide into your tits. He groans with pleasure as his orgasm builds. You squeeze your tits even more tightly around his pistoning shaft.

"Oh God!" He cries. "Joy, I'm going to cum. I'm going to cum any second!"

His soapy cock slams in and out of your cleavage and the weeping head of his prick prods your tongue.

Should you let Tommy cum? If so, how should you let him?
