Your mother

As you step into the hall, you spot your bikini-clad mother Christine walking up the stairs. She's whacking at her hair with a towel, drying off from the pool as she heads toward the master bedroom. What really catches your eye, though, is the mess of cum dripping out of her bikini bottom and down her leg. Her swimsuit is totally askew, one strap pushed down and the other barely holding on to her plump thigh.

"Hey sweetie," she says with a smile, beginning to wrap the towel around her head. "Greg was in quite the hurry to get inside me... Did you blueball your father again?"

Embarrassed, you move to put your hands in your pockets before realizing you aren't wearing pants. "Um, yeah, I guess. The girl was hot, I was horny... That's okay, right?"

"Absolutely," she replies with a giggle, before leaning in to peck you on the cheek. "I just hope you got what you needed. Something's got you really worked up today... I can't remember the last time you were so horny, especially just after coming back from April's house."

You stifle a laugh, unable to tell your mom the truth: that this is the first day of total sexual freedom, and you're ready to take full advantage. Just on queue, your cock begins to stiffen again, and you form a new plan.

"Well, uh... I am feeling a little worn out, yeah, but I'm still horny. I think I'm gonna take a rest in my room... You don't mind joining me, do you?"

"Aw, of course not!" With that Christine continues down the hall, and you watch her thick ass jiggling as she makes her way into your bedroom.
