Give her a chance

You decide to give her a chance. After all, she has just spent like 12 hours strapped to your cock without a single dose. You even fucked that neighbor girl in the ass while she licked your balls underneath. You fed the neighbor girl the dose right in front of her then made piggy clean your cock. She probably got a bit from that, right? And now with that trampstamp...

"Hehe! Yay! Anal! Whooooo" she exclaims. You look at her closely.

"How dumb is she getting?" you wonder aloud. Bet she doesn't even test any more. You begin to feel that emotion you seem to have forgotten all those years ago. Pity, I think they called it? Empathy?

Whatever it is you hate it, but the bitch seems to need her medicine.

You land a direct kick/shove on to the collection of pens, some of which disappear into the void in the process, sending her falling back down into the piss with a wet thud.

"Alright piss piggy! You have one minute to make me cum before you're out of here!" you quickly set a timer for one minute then start it immediately. "Go, go go!"

The sudden shock and pain brings her quickly out of her reverie. As she wheels quickly around to stuff your cock in her mouth several pens scatter to the floor.

Before 10 seconds have passed she is already working an incredible deep throat rhythm. She was pretty experienced at this for sure, and likely even used to assholes like you giving her arbitrary time limits.

"Go on piggy! Faster faster! I'll never get off like this!" you lied, only 15 seconds and you were already getting close. "Work the balls piggy! Quickly!" you say, hoping to distract her.

She pops off quickly and has both balls in her mouth before you know it, never breaking stroke rhythm with her hand. Shit.

35 seconds left and fading fast. You try desperately to think unsexy thoughts, buying you a few seconds before her technique changes, slamming her own face violently into your pelvis with each thrust. As she does so she continues to suck and swallow so hard you figure she's trying to coax another couple inches out of your body to cram down her throat.

20 seconds. With every upstroke she licks the head of your dick fast enough you swear she'd lick a tootsie pop down to the core on each stroke. The owl would be impressed. It's doing damage rapidly. You crush her nipples between your fingers roughly to distract her. She moans deeply but does not slow down. It feels even better.

10 seconds. Home stretch now. You watch the blur at your crotch as you loudly begin to count down from 10.
