With a final shove you bury yourself to the hilt.

With a final shove you bury yourself to the hilt. She yelps. You feel bigger inside her than she has ever thought possible. You pinch her clitoris in hopes of making her peak again, and get your wish. Her body squirms in orgasm but can't go far. She is pinned like a butterfly on a board. She moans and whimpers.

"Say you want it! Beg me to fuck your butt!" you begin to move. "Do it, John! Please fuck me, fuck my butt!" her heels drums on the bed. You pump your hips a little faster. She can't form words any more, just babble and moan. Faster and faster you drive into her asshole.

You feel yourself racing to the finish line. She goes wild feeling you swell inside her. With a loud series of groans, you come. The hot tide shoot up her butt, a more intense feeling than she ever imagined. It pulse again, again and again. She screams as you fill her, screams as she comes.

Huffing, cover in sweat, you roll off of her. Your now-deflated dick slides out of her rectum. She knows emptiness. "Oh, god," you pant. "That was hot. Thank you." Your wife has no words. She lays back, breathing hard as if she had just run a marathon. She sighs, long and drawn out. She wonders what you would do next to her. Very soon, she will find out.
