Slide up and off of him and jerk him onto your ass

You work your hips with Tom's fat cock filling up your tight little twat. It's swelling to a huge size, juicing you up with his oily precum, and you can feel by the building tension in Tom's thighs that Sara's husband is about to fill you with a hot load. You're greedily sucking on Sara's tit, but you have enough presence of mind to know that you're unprotected and letting him cum inside you would be a bad idea.

You release Sara's nipple from your mouth and sit up straight on her husband. Gazing down at Tom you see his face contorted in pleasure. The old man is obviously too lost in the rippling grip of your tight pussy to be thinking about knocking you up. You lean forward and in a deft move of your hips you slide up and off of him, then drop down to sit on his abdomen. You twist and reach back and grab his wet dick in your hand. It's burning hot and purple-red and dripping with precum. You stroke it and moan for Tom to, "Cum, cum all over me!"

The slippery head of his dick is pointed right at the smooth peach of your ass, close enough to leave wet little spots as it touches your skin. Sara quickly moves between her husbands legs and places her hands on your ass.

"Cum on her, Tom," she moans. "Her little ass is waiting for it."

Sara pulls apart your ass cheeks so that her husbands throbbing pecker is aimed right at your little pink butthole. You moan rub his cock against your sensitive sphincter, letthing him feel the heat of your body.

Tom cries out something unintelligible and you feel his fuckmeat pulse in your palm. A moment later a fat glob of white cum spews out and splatters in your crack. He pumps out a heavy load all over your asshole and in your ass crack, dripping down of your swollen pussy and onto his tummy.

Sara pushes you forward on her husband and starts blowing the last of his load out of his cock. You lean forward and kiss her man and then gasp a moment later as you feel Sara's tongue in your ass, licking out the big, sticky load her husband just put there. You push back against her mouth and savor the sensation of her talented tongue tickling your taint and slurping the spunk from your pussy lips. Sara's tongue flicking against your goo-smeared pucker drives you crazy and you moan and gasp into Tom's kiss. You can tell by Sara's eager tongue and lusty moans that she doesn't intend to miss a drop of her husband's spunk.

It's going to be a very long and very fun night.
