As I begin to soften in her mouth she draws her head back letting my cock fall with an audible plop. I look down at my mother in laws face and see she...has a small dribble of cum running down her chin. “you missed a bit" as I motion to her chin. She licks her lips then her finger wipes the small dibble of her chin then she sucks her finger clean.“You look like you need a cup of coffee, and I will make you something to eat" Jenn says as I sit on the bench with my head still spinning. I watch Jenn. She spread her legs as wide as they would go and in a move that was incredibly agile she bent forward at the waist and slipped her legs behind her shoulders and planted her mouth over her glistening oily cunt and gave her slit a passionate french kiss. Then she actually started talking to her pussy. “You filthy little cunt, one of these days your hunger is going to get me in trouble. You nasty little clock glutton.” Then she went back to licking herself. The whole thing was bizarre to witness. I was grounded for a week”Rachel said “the loneliest week of my life”.She then laughed “This is also where we made the boys, who would have thought they would be twins”. “It was a good thing that they liked me”I said “even after they found out you were pregnant.I remember that camper he parked there. He said messing around in the camper would much more enjoying”.I got out and walked around to Rachel’s side “come on let's go for a walk”. Rachel got out and giggled “should we get naked and walk. Instead of just jacking him off in any old herky jerky way, let's get medical. I've studied this stuff."All hands left Alan's groin, and there was a pause to prevent him from cumming.Then Susan and Suzanne leaned in close to his throbbing erection. Both of them felt their heads drawn to it as if a powerful magnetic force was pulling them down and compelling them to suck it. If nothing else, both of them had developed a strong Pavlovian reaction to its smell and taste. For Susan especially, just.
