Your brother tells you a tale of dirty, drunken debauchery

"C'mon, c'mon... Get in there." Your brother's voice wakes you; he's in the adjoining bathroom, and judging by the heavy footsteps, so is Mom. "Let's get you hosed down."

Then the shower starts, and Cassidy emerges wearing nothing but one of Dad's old bathrobes.

"Morning," you groan. "What time is it?"

"No idea." There are huge bags under your brother's eyes, and he's shuffling around like an old man.

"You look terrible. Did you even sleep?"

"Sorta... I crashed in the living room, with some of the guys. Still a buncha them down there," he mumbles.

"Wait, what?" You sit up in bed. "Is Dad home?"

"He came home while you were buttfucking Mom," Cassidy chuckles. "Don't you remember?"

"Not really... Guess he really doesn't care anymore, huh?"

Your brother shrugs, collapsing into the chair in the corner. "Sure, but I'm glad he didn't see what we got up to later on.

"Enlighten me."

"Well, after you turned in, a bunch of us decided to just throw down some pillows and blankets and shit... Like a sleepover, y'know? All of us crashing on the living room floor, with Mom in the middle. I was right beside her... Should've picked a better spot, though, 'cause I kept getting woken up. None of those dudes are heavy sleepers, apparently."

"What do you mean?"

"I swear to God, every five minutes someone had to piss or bust a nut or whatever. They used Mom for all of it... Whenever I was catching those good Zs, some asshole would start pounding her into the floor."

"Huh," you grunt, stroking your cock a few times beneath the sheets. "Was she still drunk enough to let it slide?"

"She was drunk enough that she didn't even wake up... Not that I saw, anyway. Not even when Tom woke up, rolled on top of her, and jammed his big 'ol donkey dick up her ass. Fuckin' savage."

"Don't act like you were an innocent bystander. I know you," you say with a chuckle.

"Sure, but I just sorta jerked off on her face. Not just me... Buncha guys painted her too. Couple busted a nut in her mouth--"

"And you let them?"

"Eh, like I said, I was sleeping. Woke up too late to stop 'em."

"Dude, if she drinks too much, gets her IQ back--"

"Yeah, yeah. Don't worry, we fucked her brains out pretty good... That plus the booze and food should keep her in a dumb-fucktoy-coma long enough for the jizz to wear off."

As if on cue, Mom waddles out of the bathroom, naked and dripping-wet. "My head's fuzzy," she murmurs.

"You probably just need more cum," your brother replies, beckoning her over. "C'mon, on your knees."

"You'd better not," you warn Cassidy as she kneels down between his legs.

"Relax, I'll bust on her tits."

"Wait, wha?" Mom looks up at him, confused. "I thought--Guuch! Mmgh, mm, mmm..." As your brother starts facefucking her, she closes her eyes and seems to accept the situation.

"Anyway, like I was saying, the guys kept using her. Mike Lane wouldn't stop drinking water, something about 'hangover prep.' Chugged a glass every time he woke up... And he woke up a lot, 'cause he needed to piss every five minutes."

"Please tell me he didn't--"

"Relax, he only went in her mouth the first few times. I told him off, and he started going in her other holes. Still, he wasn't the only one to let her swallow some... Hm, I wonder..."

Trailing off, your brother slaps Mom's tits a few times. She twitches and makes little noises of distress, but it's far less than you expected.

"Meh, guess it's mostly worn off. Partial piss-whore," Cassidy laughs, before returning his hands to Mom's head and pushing her deeper.

You grumble a bit: "should we really be talking about this in front of her?"

"Chill, she's basically just a fleshlight right now," your brother replies.

After a moment's consideration, you nod. He's probably right... Hell, he's certainly TREATING her like a toy. It'll be fine.

"Did you feed her, at least? Can't let all this exercise fuck up her curves," you continue.

"Ordered a few pizzas at 2 AM. You ever jerk off with a slice of Hawaiian?"

Rolling your eyes, you hop out of bed. "I don't get why you still jerk off," you say, grabbing your mother's hips and pulling her back until she's on all fours; it takes some effort, but soon you're lining your cock up with her pussy. "Plenty of holes right here."

"Eh, I dunno. Maybe sometimes I deserve better than her," he replies with a grin. "Speaking of which..."

You zone out a bit as your brother pulls out his phone, focusing on plowing Mom as he puts on a video... Judging by the exaggerated sex noises and high-pitched moaning, it's either hentai or some JAV. Cassidy keeps one hand on your mother's head while the other swipes between videos, bringing him to orgasm faster than Mom could alone.

Pulling out, he lets his cock flop across his mother's drooling face as it erupts, spewing cum across her hair and back. She hardly seems to notice, half-asleep even as she's showered in jizz and mounted from behind.

Soon you finish as well, filling her pussy before going back to bed. You leave her on the floor, where she naps quietly. Finished for now, Cassidy stumbles off to who-knows-where... But he must have woken some of the other party-goers, because fifteen minutes later four of them come in to drag Mom back downstairs.

"Sure, she's all yours," you mumble from the bed. "Go nuts."

You're tired enough that it doesn't register that one of the men was your dad. You find out later that he joined the after-party, enjoying the rare opportunity to fuck Mom without you or Cassidy interfering.
