Are you playing the game?

You sit on the oversized sectional in the living room, laptop warm on your thighs. Your stepdad Mark is back from his trip earlier than expected, and the whole blended household is home tonight. Mark, forty-five, stays fit with a broad chest and salt-and-pepper hair. You are twenty-two. Your brother Alex is twenty, lean and cocky. Your stepmom Vanessa is forty-one, elegant with long dark waves, sharp cheekbones, and a toned yoga body. Your stepsister Kayla is twenty-four, tall and athletic with powerful thighs and a teasing grin. Your half-sister Mia is nineteen, petite and bookish with blonde hair and glasses.

Boredom led you to download The Game of Temptation. The app launched and you clicked Everyone plays by mistake. It scanned the house and listed everyone: Mark, Vanessa, Kayla, Alex, Mia, and you. A cartoon devil with a massive throbbing cock winked. You chose Free your mind. The glittering board filled the screen, and the sultry voice declared that the game ends only at total moral bankruptcy.

Footsteps sounded. The whole family filed in, drawn irresistibly. Mark in loose shorts, Vanessa in a silk robe over lace lingerie, Kayla in a sports bra and tiny boy shorts, Alex in boxers, and Mia in an oversized hoodie and thigh-high socks.

The game began. Vanessa landed on Preference Probe. She answered aloud, cheeks burning. “I have fantasized constantly about the younger men in this house, about their cocks stretching me, about being used like a whore by my own family.” Her nipples hardened. The pink glow hit her. Her posture turned slutty, hips swaying as she sat and rubbed her thighs together.

Your turn. You rolled and landed on Body Tune-Up. The questions assaulted you.

On a scale of one to ten, how much do you love having a big, dominant cock? You typed eight. The game rejected it. Adjusting. Intense heat flooded your groin. Your cock twitched, then shrank rapidly from its usual thick six inches down to a pathetic three-inch nub, then smaller, shriveling into a tiny, ultra-sensitive button leaking precum. Your balls pulled tight. Panic exploded in your chest.

Next question. How do you feel about thick, plush asses on yourself? You tried to fight, but your fingers typed ten. Burning pleasure erupted in your hips and glutes. Your ass swelled dramatically, cheeks ballooning into huge, soft, jiggly mounds that stretched your sweatpants obscenely and lifted you slightly on the couch. The new weight felt heavy and sensitive. Every shift made your fat ass cheeks wobble.

Would you rather fuck or be fucked? The answer locked: Be fucked. Filthy images flooded your mind: getting bent over, your new massive ass spread wide, holes filled and pounded until you screamed. Your shrunken little cocklette throbbed uselessly.

Kayla landed on Truth Serum. “I have always wanted to dominate my little brother, pin him down, and fuck his face and ass until he begs,” she confessed. Her body improved: tits swelling larger, ass turning into a tight, muscular bubble perfect for riding.

Mia landed on Bimbo Foundations. Questions poured in. Favorite color? Pink. Ideal lips? Huge, cock-sucking pillows. Intelligence versus sex appeal? Her answers flowed. Her glasses vanished. Platinum blonde hair cascaded down her back. Her lips plumped massively. Her small tits ballooned into big, bouncy fuckbags that strained her hoodie. Her brain softened. “Like, oh my gawd, this feels so good,” she giggled breathily, already rubbing her wet pussy through her panties.

Alex landed on a space that pumped his cock bigger. It tented his boxers obscenely, a thick nine-inch monster. Mark received a command to stroke himself openly while watching, his own cock hardening as he stared at your transforming body.

More preference questions hit you. How do you feel about sucking cock? You resisted, but the game forced the answer. Love it. Images of drooling on thick family cocks filled your head. Your tiny cocklette spurted a weak dribble of cum. How do you feel about being called a good little slut while your fat ass gets fucked? “I love it,” you moaned aloud as the words typed themselves. Pleasure crashed through you. Panic flared hot, then melted into desperate arousal. Your massive new ass clenched with need. Your shrunken dicklette stayed hard and leaking constantly.

Vanessa stripped fully, revealing her dripping cunt. “Watching my stepson’s big cock shrink into that useless little clitty while his ass balloons into a perfect fuck cushion is making me so wet,” she groaned. She dropped to her knees in front of you, yanked your sweatpants down, and sucked your tiny cocklette into her hot mouth. She bobbed eagerly, tongue flicking the sensitive nub while her hands groped and spread your enormous ass cheeks.

Kayla moved behind you. “Such a fat fucking ass now, bro.” She spread your huge cheeks wide, exposing your tight pink hole, and dragged her tongue across it. You cried out in humiliated pleasure as she rimmed you sloppily, tongue pushing inside. Mia pressed her massive new bimbo tits against your face. “Suck on my titties while they play with you,” she cooed. You latched onto a fat nipple, sucking hard as waves of submissive bliss drowned your panic.

Mark and Alex watched, stroking their big hard cocks. Alex grinned. “Look at our brother turning into a cock-hungry butt slut.”

The game kept going. Mental changes deepened. You felt your thoughts pinkening, resistance fading into eager slutty urges. Your huge ass jiggled with every lick and suck. Vanessa deep-throated your tiny cocklette while fingering her soaked pussy. Kayla pushed a thick finger into your virgin ass, stretching you open. Pleasure exploded. Panic tried one last time to fight, but it dissolved into pure needy heat. You pushed your fat ass back onto her finger, moaning around Mia’s tit.

The women rotated. Vanessa sat on your face, grinding her dripping cunt against your mouth. You licked desperately, tasting her sweet juices while Kayla finger-fucked your ass faster. Mia jerked your pathetic little cocklette with two fingers. Mark and Alex stroked themselves, leaking precum as they watched you submit.

The game announced the next major choice. Your piece glowed on a branching space.

To the right more risk of bimbofication and sissidom but more safe spaces, but to the left all risks of punishments and transformations, but some that look like might bring back your cock size.

Vanessa ground harder on your face, smearing her juices everywhere. Kayla added a second finger deep in your ass, stretching you. Mia bounced her huge tits in your hands. Mark and Alex stood close, their big cocks throbbing near your head.

The family waited, breathing heavy with lust, as the game demanded your decision.
