To the rest of the world, maybe, she is my daughter's twin, but only my Katherine has the shining beauty that I'm in love with. It's the outlandish co...nfidence that takes her out riding in her underthings, that sheds her top in the summer. My wife is stiff, practiced. Never wild. Not like my Katherine.Last Fourth of July, before her senior year at University, we cooked out on the dock. There's a little lake in the middle of our fields. Most of it manmade, but stocked from time to time with. Then I heard Rich cry out with a loud extended "aaaaaaaggggghhhhhh" and I knew that my wife's pussy was in the process of being filled with another man's cum.

She was making sure she got every last drop of cum from his balls as his extended orgasm continued.Jennifer then cried out "ohhhh, ohhhh, I'm cumming again. Fuck me, Fuck me. I want all of your cum inside me. Oh god -- yesssss, yesssss. A soft humming sounds , and Jane suddenly feels her breasts swell in the flasks by the vacuum which creates the machine . When all air is extracted from the two flasks you see the breasts are painful purple-blue . The Master turns the taps on the flasks and turn the machine off then .The Master allows the head of the table pockets and takes the gag out of her mouth .

Then he. ” i am going to cum” i told her but she didn’t seem to care as she was now riding dinesh’s cock like there was no tomorrow, sweat and saliva and pre-cum dripping down from her mouth onto her bouncing tits. ” i’m going to cum in your mouth” i managed to tell her just before i felt my cock begin to twitch and start shooting my hot creamy cum straight into her mouth and down her throat. She has never ever let me cum in her mouth before so i can assure this was a most unexpected surprise.After.
