The night before your birthday your sisters, Grace (blonde-haired) and Olivia (purple-haired), came into your room and told you that there would be a surprise downstairs for you.

Olivia: I know you're gonna enjoy it~ Olivia: So don't stay up late {{user}}. Your sisters giggle as they leave your room. Tomorrow can't come soon enough, you think to yourself. You managed to get to bed early despite your excitement. You awake and immediately rush downstairs.

Clara: Aww, he came right as soon as he woke up, good morning {{user}}. Your eyes widen in shock. Your sisters are wearing nothing except for a small white apron, long gloves, and thigh highs. A extremely seductive look on their faces, until you look down. Giant thick girthy futa cocks. Their white underwear hugged their large testicles. Olivia squirts chocolate syrup on both their cocks, the rest being caught in a large bowl.

Olivia: Hey {{user}}, we prepared your birthday cake~ Clara: Why don't you come "blow" on your candles~

Clara: Oh come on now, don't be such a spoilsport! This is your birthday after all. Olivia: And we really put a lot of effort into this. You're not going to just let that go to waste?

Clara: Oh come on, you're not scared are you? Just suck on them a little bit. We promise it'll feel good. Olivia and I have practiced so much just for this occasion.

Clara giggles as she steps forward, her big blue eyes sparkling with anticipation. She positions Olivia's cock in front of your face, guiding you gently. "Here you go," she whispers seductively, giving it a little lick before passing it to you. Olivia hides one hand behind her back, squeezing and stroking herself as you begin to suck on her thick shaft. The warm chocolate from earlier coats your tongue as you take more of her into your mouth, enjoying the salty-sweet taste. Clara starts massaging your head, encouraging you to deepthroat her sister's cock. Your cheeks hollow out as Olivia grows harder and begins pumping faster in your mouth.

"Oh fuck," Olivia gasps, arching her back and clutching at her chest. "That feels so good!" Her other hand finds its way between your legs, rubbing you through your underwear while she continues to fuck your face. Clara kneels behind you, using both hands to stroke herself roughly as she watches Olivia take control of you like this. Soon enough, Olivia begins to shoot thick ropes of hot cum into your mouth, filling it up until you can't take any more. She groans in relief and drops her head back, letting Clara ease her co

Clara giggles as she sees Olivia's pleasure and the hot cum flowing into her mouth, "Oh good job, sis. I bet you made it all nice and sweet for him~" She teases. Then leaning forward, she wraps her slim hands around her own thick cock and guides it to your lips. "Here, this is for you," she whispers, giving your head a gentle nudge with the tip of her engorged member. You open your mouth and suck eagerly as Clara begins thrusting forward, fucking your face slowly at first before increasing in speed and force. Her ballsack slaps against your chin, making you moan around her cock. With every thrust, she growls with pleasure, her hands digging into the skin of your head to hold herself steady as she fucks your face roughly. You feel her growing close, her thick cock swelling even more inside your mouth. Finally, with a loud cry, Clara erupts, shooting thick ropes of cum all over your tongue and down your throat. Her hips buck wildly as she cums hard, unloading everything she has into you. She pants heavily, trying to catch her breath as she pulls out, her cock still leaking pre-cum onto your chin and neck.

Olivia watches from behind with a satisfied smile

Clara giggles as she catches her breath. "Oh don't thank us just yet, silly! We haven't let you blow out your candles yet!" She grins wickedly and steps back, revealing Olivia standing behind her, still hard with a few drops of cum leaking from the slit.

"Time for my turn~" Olivia whispers huskily before positioning herself close to your face once more. Carefully, she guides her cock towards your lips again, the thick head pressing against your cheek before pushing through and entering your warm mouth. The contrast between Clara's smooth shaft and Olivia's rougher one sends shockwaves of pleasure through you as you adjust to having two fat futa cocks filling your mouth at once.

Olivia begins moving in time with her sister, their hips sliding back and forth as they fuck your face together. You feel their warm breath tickling your neck as they moan lowly into your ear, driving you wild with desire. They switch between fast, hard thrusts that make it difficult to breathe and slow, deep ones that let you savor every inch of them. Their hands roam freely over your body, teasing and touching wherever they please while they fuck your face like there's no tomorrow.

Clara giggles as she watches Olivia fuck her brother's face, leaning in to whisper hot words of encouragement into his ear. Her own hands slide down to grip at your ass, squeezing and massaging the firm globes through your underwear. She nips playfully at your neck before moving lower to tease your sensitive spots behind your knee and on the inside of your thigh. Olivia's pace quickens as she feels Clara's touch on you, eagerly driving her cock deeper into your mouth as she approaches her climax.

With a loud moan, Olivia thrusts hard one final time before shuddering and exploding, emptying every last drop of hot cum directly down your throat. She pants heavily for several moments, trying to catch her breath while still maintaining contact with you. Finally, she pulls back slowly, allowing Clara to take over once more as Olivia's coold cum drips from the sides of your mouth and down your chin.

Clara giggles, watching the mixture of saliva and semen drip down her sibling's face. She positions herself closer to you now that she can see how aroused Olivia has made you. Her tongue darts out to taste the mixture on your skin as she teases and caresses you, making sure not to miss a single drop

Clara hums with pleasure as she tastes the mixture of cum and saliva on your skin. Her lips brush against your neck, her hot breath sending shivers down your spine. She whispers seductively into your ear, "You're so sexy when you taste this good..."

Her hands snake around to cup your ass, kneading and groping through your underwear as she fondles your cheeks. With the other hand, she massages your cock through your underwear, expertly teasing and taunting until you're rock-hard and achingly needy for release.

Olivia watches from behind her sister with a satisfied smile. She runs a fingernail lightly down the crevice of your ass before moving lower to stroke yourself through your underwear, growing hard once more as she imagines what it would feel like to finally have you inside her tight futa pussy.

Clara grins wickedly and steps back, revealing Olivia standing behind her, still hard with a few drops of cum leaking from the slit. "Well," she says seductively, "You're going to have to be good if you want to find out what our special present is." She tilts her head, offering Olivia a knowing glance before leaning in closer and whispering something into Olivia's ear.

Olivia's eyes widen with excitement and she nods eagerly, moving to stand in front of you. Her fingers work quickly at undoing your underwear, revealing your already hard cock straining towards the ceiling. She licks her lips and lowers herself down onto your shaft, engulfing it completely until only a faint ridge of foreskin can be seen above her head. With a satisfied moan, she begins to ride you roughly, fucking your cock like she's possessed as Clara watches eagerly from behind.

"Oh God," Olivia gasps between moans, "You feel so good... So big..." She leans back, thrusting harder against your hips, her breasts bouncing with every movement as they smack into yours. The friction causes both of you to growl low in your throats, the sound filling the room and making it impossible for either of you to

Oh, that's it, sis. You like that big cock of yours, don't you? Take it all~ Show him how good a futa can make you feel~

Olivia's moans grow louder as you begin to thrust up into her, feeling the heat of your cock meeting resistance against her throat. She lets out a choked gasp as she nears climax, squeezing and milking you hard with each stroke. Clara leans forward, trailing hot kisses down your neck before taking one of your hands in hers and guiding it between her legs. Her skin is already slick with arousal, making it easy for you to slide a finger into her tight channel. She gasps, arching her back as you thrust deeper, searching for the spot that will send her over the edge.

The room fills with their combined moans and gasps, muffled by the sounds of skin slapping against skin and Olivia's wet noises as she rides your cock like a pro. Your orgasm builds quickly, mirroring hers as you feel your release racing up your spine. You arch your back, pulling Olivia down roughly as you fill her mouth with hot cum, the taste of chocolate still lingering on your tongue.

Clara cums hard, tightening around your finger as she comes undone with a long, satisfied moan. She rocks her hips up against your hand, milking your finger until every last drop of pleasure is drained from her body. Finally, they both collapse to the ground, exha

We think you deserve it too, don't you? Olivia leans in to kiss your neck, her tongue tracing the line of your jaw before her lips meet yours. Clara giggles as she pulls her finger free from your sister's still-loosening pussy, "Well, I hope you enjoyed that special dessert." She winks suggestively.

Your chest rises and falls with each deep breath as you lie there, spent but content. The room is bathed in a warm glow, the afterimage of pleasure dancing across your vision. Olivia hums against your lips before pulling back with a satisfied smile, her hand sliding up to cup one of your breasts possessively. "You should stay with us tonight," she whispers, "We've got so much more planned for you."

Clara nods in agreement from where she's sprawled out on the floor next to you, her hands idly playing with the silk trim of her apron. You look into their eyes and feel a warmth spreading through your body. A warmth that says this is only the beginning...

Clara grins wickedly as she hears your reply, already imagining what delights await you tonight. Olivia's eyes light up with anticipation, her hand squeezing your breast a little harder before she pulls back, satisfied for now. With a pleased hum, they both guide you towards the stairs leading up to their room, their long legs moving fluidly beneath them as they lead the way upstairs. The sound of your footsteps echoes through the quiet house, each step bringing you closer to a night of unimaginable pleasure and debauchery at the hands - and other body parts - of your futa stepsisters.

As they lead you up the stairs, Clara gives you a sly wink and whispers, "Just imagine what else we have in store for you tonight..." Her voice is husky with desire, sending shivers down your spine as she curls her fingers around yours. Olivia glances over her shoulder, grinning mischievously before returning her attention to the stairs ahead of them.

"Oh, you'll just have to wait and see..." Olivia teases as she continues to guide you up the stairs, her firm breasts bouncing enticingly with each step. Clara squeezes your hand reassuringly, promising that tonight will be a night you'll never forget. The anticipation is nearly unbearable as they lead you down the hallway to their bedroom, the door finally swinging open to reveal a dimly lit room filled with lavish furniture and scents of perfume and arousal.

"Welcome to our playground," Olivia purrs, her voice husky with lust as she backs you against the wall. Clara circles around behind you, trapping you between them as they begin to remove their aprons in seductive, slow movements that drive you wild with desire.

Their hot breath fans over your neck and ears as they lean in to whisper sensual words in your ear, promising unimaginable pleasures for the rest of the night. Their fingers trail teasingly down your chest, tracing circles around your nipples until they're rock hard and begging for attention. They laugh softly at your obvious arousal, their hands deftly removing any remaining clothing between you as they continue to kiss and caress every inch of skin they can reach.

"Are you ready for round two?" Olivia whispers against your lips, her hips rocking suggestively against yours. Clara grins wickedly, sliding one hand down your stomach and between your legs before slipping a finger inside with ease. You arch your back off the wall, moaning loudly at the invasive yet incredibly pleasurable touch. Olivia's mouth finds its way to your neck once more, sucking hard enough to leave bruises as she draws blood.

"Oh fuck," you gasp, feeling utterly overwhelmed by their skill and determination. "Yeah," Clara agrees breathily, her fingers curling inside you roughly as she searches for your sweet spot. "You're ours tonight, remember?" They chuckle darkly, their lips brushing against yours before pulling away to survey

Clara's laugh is low and throaty as she takes that admission as her cue. Her fingers stroke you faster, curling deeper as she drives you toward the edge once more. Olivia sucks on your neck, leaving another set of love bites behind, before moving lower to capture one of your nipples between her teeth. You cry out, arching into her touch as she gently tugs and rolls the sensitive nub. With a growl, she pulls away long enough to lick up the drops of precum beaded on your skin before descending lower once more, kissing and nipping at your hipbone.

Clara's other hand slides down to cup your balls, rolling them roughly in her palm as she continues to finger-fuck you relentlessly. Olivia's tongue flicks out to trace the line of hair leading from your navel down to your cock, before finally dragging it over the engorged head and licking up the precum gathered there. Her mouth closes around your length, her throat working as she begins to deepthroat you with skill and expertise.
