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

John keeps still as Rachel continues to ride his thick cock. He can feel her pussy lips literally grabbing his shaft as she pulls her pussy forward, letting some of his cock come out of her body, then again as she rocks her hips back and absorbs his shaft back into herself to the hilt. Each time she bottoms out, John can feel his cockhead pushing hard against her cervix. She presses her lower body down as hard as she can and works hard to keep her pussy pushing down as hard as possible. John’s cockhead pushing against her cervix hurts her but gives her immense pleasure as well. She can actually feel his cockhead forcing her cervix to open slightly when she presses down this hard. Thinking about how much easier his sperm-filled semen will enter womb on their journey to find her fertile eggs makes her feel useful and fruitful.

Rachel starts to rock her hips side to side when she bottoms out and feels his giant cockhead pushing against the entrance to her womb and can actually feel her cervix spreading even more, allowing the top half of John’s cockhead to actually enter her womb. When she rocks up to let John’s cock come out her cervix naturally closes, but after John’s cockhead pushes into her womb through her cervix more than fifty times, it loosens and make the penetration of John’s cock directly into her womb easier.

Disregarding the pain, Rachel rocks faster and pushes her pussy down onto John’s massive cock harder, forcing more and more of his cock into her uterus. She can feel her body reaching the point of no return, signaling to her the oncoming orgasm, but this one feels a bit different. It feels primal and genetically ancient. She grits her teeth, grunts loudly and slams her pussy down as hard as she possibly can. The incredible feeling John’s massive and unique cock is giving to Rachel triggers her body to make the ultimate connection by triggering ancient pleasure centers and reproductive behaviors.

When Rachel slams her pussy down, John’s cock rushes into her pussy, slams against her cervix, and completely passes through into her womb. John’s entire cockhead enters her uterus and becomes lodged very securely by her cervical muscles. The prying open of her cervix by John’s cock and the subsequent penetration of her uterus makes Rachel’s cervix clamp down around the crown of his cockhead and her pussy muscles grip his thick shaft like Velcro, immobilizing him inside her.

The feeling of having her boss’s cock so deep inside her triggers the most massive orgasm Rachel has ever experienced in her life, making her tense up like a steel beam, her mouth hanging open and her lungs desperately trying to suck in more air. Rachel drools from the corners of her mouth and the drool slides down her chin and drips onto John’s chest in a steady stream.

Rachel can feel her entire pelvis heating up like a furnace, making her skin tingle and itch. Her asshole flexes and relaxes releasing juices from her bowels uncontrollably. Her spine is so tense she feels it will snap in half. Her brain is on fire, incensed with pulling John’s cum from his balls.

John can feel his cockhead punch through a part of Rachel’s body deep inside her when she slams her pussy down like a hammer on an anvil. The feeling of his cockhead pushing through to her inner depths brings him to the brink. What really sends him over the edge is Rachel’s pussy muscles squeezing his shaft even harder than before, and the incredible heat emanating from her body. It’s nearly unbearable. This triggers a base and primal part of John’s brain forcing an incredible amount of blood rushing through his cock and balls.

“Oh my god, John! your cock is inside my womb! Please, please fill me with your seed! Fill my womb with your life!”

Hearing those words propels John’s orgasm into overdrive, his body pumping massive amounts of reproductive hormones. His cock erupts more than two dozen streams of thick, sperm-filled cum directly into Rachel’s uterus, the force of the orgasm pushing the sperm-filled semen into Rachel’s Fallopian tubes, filling them all the way to the ovaries themselves. The two eggs in each of her Fallopian tubes become surrounded by millions of John’s sperm, poking and prodding, both eggs becoming joined by a sperm to create new life.

Both Rachel and John scream out loudly from the gut, almost sounding like animals as they embrace and fuck. Rachel’s pussy and uterus holds onto John’s cock, keeping his cum locked inside her womb for nearly twenty minutes as their bodies wind down from their coupling. John remains hard and Rachel is in no hurry to have John’s cockhead leave her uterus or his thick hot shaft leave her birth canal.

“John, I never want your cock to leave my body. Do you think you can stay hard and bring me to your home with your cock embedded inside my womb and pussy?”

“I can try, Rachel.”
