Not a chance

You look down at your aunt. Her legs are spread wide, and you can see her stretched pussy glistening, and waiting. She's rubbing her tits, pushing them together. She smiles a wicked smile.

"Come on, stud. Don't you want to fuck me? Don't you want to stick your big, hard cock in your Auntie's pussy? Make me moan, stud." She sticks her tongue out and licks her lips.

"Oh.... Auntie..."

"Are you gonna fuck me hard? Fill me up with your hot cum? Bend me over and make me-"

"Unnnnnnnnnnnnggghh..." You cut your Auntie off as your prick erupts, spraying your cum all over her cunt.

"Oh shit oh shit oh shit..." you stammer as you realise what just happened. You didn't get to fuck your auntie. Instead you prematurely blew your load all over her.

"Wow... such a big load, stud. It's too bad you didn't get to fuck me with your huge cock. Hahahahahaha!"

Your auntie's mocking laughter rings in your ears. You look down at your shrivelling penis.

"Ok, stud. Time to clean me up."

You look at your auntie in horror.

"I'm serious. I don't want your loser cum on my pussy. Get down there and lick me clean. Now!"

You swallow and dip your head down to her pussy. You can smell your cum mixed with hers, and while you find it unnappealing your penis twitches. You stick your tongue out and take a big slurp. It's salty and gooey. You keep slurping and swallowing, trying to lick up every drop.

"That's right, honey. Lick up all your cum."

You feel like you've cleaned most of it up and you look up at your aunt. You stick your tongue out to prove that there's none left.

"Very good. Now get out. I'm putting you back in chastity first thing tomorrow morning so make the most of it."
