I've devised an eight point plan that enables a guy to have fun should he be able to nab that elusive babe: The big-titted girlfriend.
POINT 1: Don't call them tits until she does or she allows you to. I dated a massive-titted girl for three years and she was very proper and never referred to them as tits. Still, I sucked and fucked those babies all day and night. Sucking on huge breasts or having "boob sex" as she called it, is still great if the tits, excuse me, boobs, are big. Meanwhile I've had girls ask me if I wanted to fuck their tits on the second date.
POINT 2: The double nipple suck. Girls have to be pretty well-endowed for you to do this but it's great to push two big titties together and suck on both nipples at the same time. The girl gets off on watching and knowing how much you're enjoying it. And occasionally if she's big enough she will help you out by sucking on one or both of her tits. I meet a girl in a bar one night and was making out with her in her car when she removed bra, took her boobs out began to suck on them. "Does this turn you on?" she asked me as she began to remove my shorts. The size of my huge erection quickly answered her question. Plus, this is a very cool visual.
