Mostly, I like to make a woman get a squirting orgasm, and I never can get that while long-dicking her. But OMG, long-dicking is the best tease!!
My LD method is to distract and surprise her. Depending on the position, I'll tweek her nipples, lick her neck/ears, do some trash talking and then, WHAM!, thrust it all the way in. She screams out and begs for more. Then, if she tries to thrust herself on my dick, I always pull back and make her wait until I'm ready. I tease her like that for a while. It drives her crazy-mad and then I just ram her non-stop 15-20x. Change positions and start all over again.
