I fake orgasms on the reg. But in my case I'm pretending to not be having an orgasm when, in fact, I actually am. Textbook move to keep you from looking like a chump. Best way is to pull out, go down on her --pretending you got the sudden urge to service her at the foot of the bed -- and leave your business all over her carpet. Wait a few minutes for your d*ck to recalibrate and then bang her like a champ for the next hour. Then, when she leaves to go to the bathroom after it's over, make sure you rub your soldiers into her carpet or just slide them under the bed if it's a hardwood floor.
