Madison helps you throatfuck her sister

Without another word, you help Madison up and head back into Christina’s pink palace of a bedroom. Even in the aftermath of your first ****, the place looks untouched... except for the sobbing, cum-dripping big sister curled in a fetal heap on the bed.

Christina’s head snaps up as you enter, blue eyes already leaking new tears. As she takes in Madison at your side, her expression turns from fear to outright horror. “No. No, not her! David, what the FUCK, she’s just a kid!”

Madison snorts, wiping snot away from her nose. “Right. Like you ever cared.”

You stalk over to the nightstand, yanking the drawer open. Sure enough, there’s a little spiral diary with “PRIVATE” stenciled in block letters. You flip through the pages, skimming over the hearts and doodles until you land on a passage that makes your cock twitch:

“David is such a pathetic little PAWN. Can’t believe he got hard watching me eat a banana in homeroom. Bet I could make him cum in his pants before he ever got to second base. Maybe I’ll try it after homecoming…”

You grin and read the passage aloud. Christina’s cheeks go purple. Madison starts cackling.

“Oh, but it gets better,” you say, thumbing a few pages ahead. “Here’s a list of all the guys you blew before the winter formal. That’s a lot of names, Christina. And here I thought you couldn't handle my cock.”

"Leave me alone, please," Christina gasped.

"Nuh-huh," you say tauntingly, landing on a particularly juicy page and reading it out. "I want to be used. Like, really used. Not just ‘give a guy a handjob at a party’ used. I want to be facefucked, throatfucked, like a pornstar who doesn’t have a safe word. Like a real cocksleeve. I want some guy I hate to cum down my throat and not even care if I ****. I want to be held in place and humiliated and covered in spit and cum and have them all laugh at me after. I want to drown in it. Am I sick???"

Madison leans over your shoulder as you read, relishing every line. She glances at her sister and laughs. “Told you. She loves this shit.”

“I-it was just a fantasy,” Christina chokes. "Please, stop!"

But you aren’t stopping. You kick her off the bed, hauling her by the roots of her ruined hair until her face is mashed inches from Madison’s. “You wanna show off for your little sister, bitch? Open your mouth. Right. Now.”

Christina hesitates just long enough to make you want to backhand her, but Madison beats you to it. A sharp slap, perfectly aimed. “Don’t make him ask again,” she says.

Christina’s lips open. You shove your cock inside, burying the shaft past her tonsils in one smooth motion. Madison’s hands grip her sister’s hair at the crown, holding her in place as you piston in and out, using Christina’s mouth with no more mercy than before. The spasms in her throat are pure animal panic, but Madison’s hands are implacable, yanking her head down on your cock so the tip pounds again and again against the back of her ruined throat.

This time, Madison is the one in control. She’s got a vice grip on her sister’s scalp, twisting and shoving so that Christina’s nose slams into your pelvis on every stroke. The pain makes her eyes go bloodshot and her whimpers take on a ****, animal note. The sounds are obscene and beautiful: a symphony of wet ****, splattering tears, and the savage cadence of your cock pistoning in and out of her mouth.

You catch Madison’s eye, and she’s clearly aroused by what's happening. The way her sister gags and shudders, the mascara-smeared spittle bubbling from Christina’s lips as your cock ruins her face, the raw humiliation oozing from every crying, trembling inch of her. Madison drinks it in, feeding on her sister’s degradation, and when you let up for a moment to let Christina breathe, Madison shoves her face right back onto your shaft.

“Don’t stop,” she hisses, her own hands trembling as she forces Christina to keep swallowing, keep ****, keep suffering. “Don’t you dare stop.”

You don’t. Not until you feel the telltale twitch at the base, the familiar surge of pressure. With a burst of savage energy, you slam forward, hilting yourself in Christina’s mouth. Madison clamps both hands on her sister’s head, holding her in place, as you paint the back of Christina’s throat with your second, even thicker load. There’s no escape for her this time. Every drop goes down, and the overflow gushes from her nose and lips in a blinding, sticky mess.

Christina convulses, eyes rolling, as she tries and fails to spit out the white-hot jets pulsing from your cock. Madison’s grip is so furious that the blonde is little more than a ragdoll, **** and gasping as you fire again and again into her ruined mouth. When at last you’re spent, you wrench free, shoving Christina to the floor. She collapses, coughing up strings of cum and bile.

Madison stands over her, chest heaving. “Look at you,” she sneers. “You’re nothing. Not even good enough to swallow.”

You reach down and smear the last dribble of cum across Christina’s cheek with your thumb, then turn to Madison.

“What's next?” you ask, grinning.
