A typical morning, one year later...

You wake up in your master bedroom, lying in the familiar king-sized bed. A couple years ago this room belonged to your mother Jenna and your father George, but Dad isn't allowed inside anymore. This is your private sanctuary, a place you can "treat" your fat fucktoy mommy without any of his judgmental glares... Not that you particularly mind those anymore. Hell, he doesn't even spend much time at home these days. He still loves his wife, but unlike you and Cassidy, he's not attracted to her new plus-sized body.

Mom's IQ has fallen even further since you implemented her new diet. You still cum in her mouth now and then, but she doesn't complain when you don't: after all, she thinks that the gallons of icing and other sweet treats you're feeding her are all semen-based. You keep telling her she's getting smarter by the day, and she believes it without question.

With a yawn and a stretch, you sit upright. The whole bed is slowly rocking back and forth, which is probably why you woke up. Looking down to the foot of the bed, you see Cassidy giving Mom an early-morning pounding.

"Heya," you mumble, throwing back the covers. Like your brother, you're wearing an undershirt and nothing else: pajama bottoms would just get in the way of your "late-night medicine administration." Judging by the dried semen that's on and around your cock, you must have been humping Mom in your sleep again... Luckily, the dose clearly didn't make its way into her mouth.

"Morning," Cassidy grunts, grabbing onto Mom's soft body as he picks up the pace. "...Gonna nut..."

Your mother's sleepy eyes flutter open, and she frowns a little. "Can you do it in my mou--"

"Too late." Your brother humps her a few more times and then pulls out, unloading onto her thigh. Without missing a beat, she reaches down and starts scooping it up with her fingers.

"Pretty sure me and Marcus used your mouth a few times last night," Cassidy says, turning away and walking towards the bathroom. "Save it for later."

With a resigned nod, Mom leans over and opens the cupboard door on the nightstand. It's almost entirely full of small plastic containers; she grabs one off the top, removes the lid, and starts filling it with your brother's load.

Wonder what Cassidy is gonna do with that one, you think, watching as she takes care to save every drop. Is he still putting it in her shampoo, or did he switch back to the moisturizer? Your brother delights in making Mom use his cum in degrading ways (without letting her actually consume it, of course). You, on the other hand, just sell your excess jizz to **** girls... Y'know, like a normal person.

As she finishes cleaning up, Cassidy heads into the bathroom and slams the door behind him. You hear the click of the lock, and realize that your plans of using the shower have been dashed. Judging by the disappointed look on Mom's face, she had the same idea; after all, you're not the only one who had a sticky night.
