A sloppy kiss

You struggle with your mouthful of sticky cum, feeling awed that your mother managed to produce so much semen in one orgasm - you've probably got more cum in your mouth and stomach than most people let out in a month.

A sudden movement out of the corner of your eye catches you off guard, and before you can react, Allison's sidled over next to you and leaned in, putting her mouth over yours and slurping up the seed that's leaked out from between your lips.

Letting out a satisfied moan, Allison leans back a bit and turns her eyes upwards, looking submissively at your mother. "May I help Jesse drink your cum, Ms. Bailey?"

Looking a little amused, your mother hides a smile with one hand. "Well...you asked so politely, and it's good for couples to have similar...hobbies. So go ahead, dear."

"Thank you, Ma'am!" Her voice fawning and grateful, Allison thanks your mother and wraps her arms around your neck, pulling her face and yours together. Her voice is an excited hiss. "You look sooo hot sucking dick like that!"

As if to prove how turned on she is, Allison presses her lips against yours before you can respond, her tongue burrowing into your mouth. You feel some of the cum filling your cheeks flow into your girlfriend's mouth, and you can feel your dick trembling as you suck at Allison's tongue, the taste of Helen pervading the kiss.

In moments, you're blissfully engaged in the best kiss you've ever had, the two of you swapping saliva and semen as you make out frantically, erotic noises filling the room as your family watches the show.

Gradually, the two of you end up swallowing the whole load between you, until you're only swapping saliva, at which point you finally break the kiss, both of you gasping for air.

You notice that your little show with Allison has given Helen and Elsie the time - and stimulation - to recover from their first ejaculations...both of them are yet again sporting sizable erections.
