I rubbed up the entire front until I was at her clitoris and then I retraced my hand down between her legs and up into her opening. She sighed and wi...gled her groin into my hand as she pulled even hard upon my back. I was prodding my finger up her vagina through the crotch of her underwear, pushing the material upward, deeper into her opening. It was getting very wet from her juices and she was vocalizing her pleasure. I suddenly removed my hand from her pussy and started ravishing her. I watched with excitement as she started to whimper and the tell-tale signs of her impending orgasm started to show. She rubbed at her cunt furiously as I watched her belly seemed to do flips, her body shook and she held onto my shoulder for support. As her orgasm subsided, she leaned forward and kissed me. I could taste our mingled pee on her lips and we held each others wet bodies close. We stepped out the bath and walked into the shower together. Melissa turned on the water and leaned back.. Mark’s cock stood firm and drooled a little precum as he concentrated all his efforts on my Dad, I could almost reach out and touch it if I had wanted to. My Dad was moaning and holding Marks head and began pelvic thrusting as he began to face fuck his best friend. The scene was so totally hot, I licked my hand to lube up my own cock some more to slide my hand up and down my own shaft backhanded with a corkscrew rotation at each upward move. The stimulation and sensation was not like any. Looking through giant microscopes, evolutionary biologists Robin Baker and Mark Bellis found that “egg-inseminators” make up only about 1% of a man’s sperm. So… what about the rest? What about the 99%? It turns out that sperm aren’t so much like a bunch of individual runners or swimmers, but more like an army or a football team. The offensive players are the tackles and fullbacks in the Big Game going on inside the female’s reproductive tract. They don’t ever even try to race to the egg because.
