(Her Secret Fantasy, continued by Ho...)

You look at the clock and it’s the middle of the night. A little after 1 am. You watch your girlfriend Rachel ride her boss John’s giant cock for what seems like forever before he grips her hips, pulls her down hard against himself, his balls tight against her twitching pucker, and begins to grunt as he fills your girlfriend’s unprotected pussy with his sperm for the… you lose count of the number of times John inseminated your girlfriend tonight.

Rachel moans and wiggles her hips back and forth then she begins to grind her pussy against John’s pubic bone and launches herself into a massive orgasm. She convulses on top of her boss for a minute before laying herself on top of him and placing her head on his chest.

Another minute and you see her close her eyes as she falls asleep with John’s cock still buried inside her stretched-out, swollen red pussy.

You stare quietly, not making any noise and keeping your breathing nice and even. You can see John flexing his cock inside your girlfriend’s pussy and each time he does, Rachel’s pussy stretches enough to make the swollen pussy lips lose blood and turn white. It’s incredible how thick John’s cock really is, and how much it expands when he flexes his cock muscles.

You stare until John’s eyes close and his breathing becomes deep and regular. Then you fall asleep as well.

You startle awake to Rachel grunting and see her under John this time around. They are in missionary position, Rachel’s creamy white legs pulled back with her toes curled up into a fist, her heels pressing against the outside of John’s hips as they rise and fall above her.

His giant cock is sawing in and out of her in a steady rhythm, pulling out of her body eight or nine inches before thrusting back into her until the big pair of tangerine-sized testicles rest flat on her ass. About one thrust per second you keep rhythm. Counting the number of thrusts John makes into your groaning and grunting wife… a hundred, five hundred, a thousand, fifteen hundred.

It took John twenty minutes of steadily sawing in and out of Rachel’s pussy to produce fifteen hundred thrusts. But it’s at this time his thrusts become urgent. Now he’s pumping into Rachel at twice the speed. Thirty seconds later, Rachel is making a sound that doesn’t seem human as John’s giant cock is a blur of motion.

As intense as it was when John was pounding his giant cock into your girlfriend, he stops just as suddenly, holds himself fully into Rachel and spasms for nearly a minute. You know John just filled up Rachel again with another one of his giant loads of sperm-filled cum. There is so much cum deposited inside Rachel’s pussy that you can see it oozing out of her around the base of John’s cock and begin to pool in the crack of her ass.

John’s body droops and he goes limp on top of Rachel who is still gasping for breath. You thought John passed out, but he turns his head and begins to kiss Rachel gently at first, but then more and more insistently until their lips and tongues are mashing up against each other and invading each other’s mouths.

Soon John begins thrusting into your girlfriend’s pussy again. A half hour later, John shoots his cum into Rachel’s unprotected pussy with another load of sperm. You look over at your clock to see it is almost six AM.

John continues to fuck your girlfriend into oblivion for the next two hours. In that time he fills her pussy with another five loads.

It really hadn’t occurred to you until you saw the two of them in the light of day, but John has had his cock buried inside your girlfriend Rachel’s pussy for the last sixteen hours, and filled her up with more than twenty gigantic loads of cum.
