Asshole

"Hm... well I dunno... I mean I guess we could... maybe try..." Liv starts

"You want your ass stuffed and filled with cum right?" you finish her thought for her

"Uh... what no! Maybe.. Does that make me a slut" she responds

"No, but you will be before I'm done with you" you say before turning her around and pulling her clothes off

She's meant in front of you and you slowly push your dick inside her asshole. It goes in without much resistance.

"You've done this before haven't you slut" you ask

"I'm not a slut... but maybe yeah" Liv replies

"So you like your ass being filled with cum until it leaks out" you probe

"I'm not... but god yes I love getting anal creampies" she responds

At this point you've been thrusting so fast into her ass that you're getting close

"Admit you're a slut and I'll fill you with cum" you say

"I'm not... Fine! I'm a slut, I'm a filthy fucking whore that love big cock in my ass! I didn't admit but I can feel you stretching my tight asshole out. You're going deeper than anyone has ever been and I just want to be full of cum already" she screeches as she actually cums from getting fucked in the ass

That does for you and you start shooting your massive load into her ass. Spurt after spurt until you pull your length out of her gaping asshole and look at your handwork. Cum is dripping out and you make sure to spread her cheeks so her asshole stays gaped as long as possible.
