So fuck him on top. A really good cowgirl fuck. Pay close attention to his body signals about when he's cumming. When you can tell he has started cumming, jump off his dick and IMMEDIATELY start sucking him off/licking his head, jacking him off with one hand, and firmly rubbing his asshole with the other hand. It's taking what Jessica Biel did in the film and making it about a million times more pleasurable.
Now it is very, very important that you can make this transition almost immediately. Although she probably wasn't fucking her movie partner for real, Biel does a great job of getting down to his cock before it's too late. The goal is for his first spirt of cum to happen in your pussy, and then for the remaining spurts to take place with your lips, tongue, and hands. Trust me, he'll go fucking bananas ;)
