Cum on her face

"Alright slut, get on your knees" you say, unsheathing your cock from her ass and pulling her roughly to the ground, facing you. She falls there in a heap, both her knees and hands on the floor, her asshole assailing her with a constant searing throbbing from the **** it just took. With a scrap of energy she didn't even know she had, she wipes away the tears and looks up eagerly at your cock, hoping to start swallowing it.

"ah, ah, ah, Jennifer. You don't get to taste this cock yet."

"..." she knelt silently, with a sad puppy dog look in her eyes.

"No, your going to sit your tight, fucked ass over there on the floor, with your back against the bed, and then I'm gonna cum all over your pretty little face."

"Yes David! Anything if you'll let me suck your cock after!" she couldn't have been happier to have your thick cock out of her shredded ass, one step closer to wrapping her lips around your cock again. She crawled slowly into position, visibly nursing were wounded asshole as every motion seemed to make it hurt more. With a deep sigh she fell into her spot, throwing her hair from side to side then laying her head back on the bed, awaiting the load that would get her closer to blowing you again.

You walked over to her slowly, taking in the view. Your uppity, too-good-for-you sister-in-law, her throbbing ass sat on the floor, her legs spread as far as the denim skirt around her knees will allow, her face and halter top stained with medals of shame and drool, eyes closed, anxiously awaiting your arrival, and your cum. She squirmed incessantly, unable to find a comfortable seated position with her torn asshole burning.

"Good Jennifer. Now if you want this cum, you're going to have to convince me. I want to hear you beg. I want to hear you say the filthiest things you can possibly imagine. I want you to feel shame the moment you say them. Then, and only then, will I grace you with a hot sticky load of cum on your face."

She needed no more prodding than that. As you rhythmically stroked your cock to the finish 3 inches from her face, she let off a litany of quotes that started as dirty, but moved on to what would make a pornstar blush:

"Shoot that hot load all over my face David!"
"Please baby, PLEASE! Cover me in your cum!"
"God I want your cum!"

"Dirtier" you say stoically, beating your cock a little faster. She got a bit more creative.

"That's it, make me your little cumslut"
"You're in charge David, use me like the cum dumpster I am!"
"I'm nothing but a target for your cum"

"You need to be filthier, or I'm going to blow my load and leave without letting you suck my cock" you threaten. She took the threat seriously, to say the least, throwing caution to the wind with her following utterances.

"I'm a worthless cock sucking whore. Spank me. **** me. Whatever you want, just blow your load on my face when you're done!"
"I can't wait to kiss Mike tonight and see him wonder what that salty taste is"
"Please cum. If I'm not pretty enough, you can cum on my daughter Amy's face instead"

And with that you exploded with a roar. Jet after jet of hot, sticky semen splashed all over her face, each impact drawing a scared yelp from her. Apparently in addition to anal, cum facials are something she's never done either. Her face was being doused, her eyes sealed shut, long thick strands reaching from the middle of her hair down to her forehead. As the cum continued flowing, you coated her cheeks and lips, splashing over her nose as well, causing bubbles to be blown as she breathed. Her yelps in between shots also allowed you to shoot a viscous glob into her throat, causing her to gag and cough violently. That didn't stop you, though, from continuing to unload jets onto the side of her face and hair, dripping down over every part of her body.

With a final sputter of cum falling short of her face and onto her denim skirt, you had finally finished defacing her. She sat there blind, unable to open her eyes. Even still, she turned her head up and opened her mouth, cum from her face slithering in. She looked where she thought you were, and begged "Please, I can't see, so can you put your cock in my mouth?"
