I remember reading an article, where you don't let the girl orgasm until you get your dick inside her. Because she already climaxed and she backward rationalizes and thinks that she doesn't need to go any further and rack up a partner count. I can't remeber the exact reasons but something along those lines.
So do we controll their level of pleasure until we get our dick inside her? Do we continue fingering after orgasm and give a chain of orgasms until we reach the end goal?
