Finally...

Unknown to Doe, you'd been naked the entire time and had taken a supplement that had enhanced your virility whilst also keeping you hard for at least two hours, this particular supplement had also enlarged your testes, making them tennis ball sized. With a nod to your doctor who'd been looking at a scan of Doe's womb and had given you the thumbs up, you slid in behind Doe and lined your cock up.

You smirked as you rubbed your cock up and down Doe's increasingly wet folds, making her gasp before you rammed your full length in, Doe's face agape with a noiseless scream as she felt your balls hit her clit as your cockhead knocked on the door to her womb. You groan as you feel her tightness wrap around your thick cock before you start hammering her, not wanting to go slow as a punishment for her trying to use your own weapon against you.

"Tell me Doe. What is your deepest, darkest fantasy?"

"Oh fuck! UGH! T-This... B-Being d-dominated a-and b-bred a-against m-my w-will... UGH!"

You moan as you continue to pound away, your balls nowhere near ready to unload their precious cargo as they hammer into Does swollen clit, making her moan and whimper as you do so. Doe grunts before you see her head slump as you realize the vacuum had just triggered an orgasm, milking her balls for their cargo.

You groan as you feel Doe's silken folds eagerly massage your cock, trying desperately to milk your balls, knowing that you can still go, you decide to grant their wish, pushing your cock as deep as you can, going so far as to breach Doe's womb, making her cry out as she feels your cock throb twice before your potent load floods her womb, Doe slumps, defeated as she accepts her punishment, she then lifts her head as you continue pumping your cockhead into her womb.

"M-My God! Y-You're not stopping?"

"Not until I get two things, you pregnant and you as my willing ****!"
