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~

Hm? Didn't we tell you last night that this was going to be a special kind of birthday cake? Olivia giggles softly and licks some chocolate syrup off her fingers while Clara places the bowl on the coffee table. With a devious smirk, she gently caresses your arm with one gloved hand before grabbing your shirt collar and pulling you close. Her other hand slowly slides up your stomach and begins to tease your chin before brushing past your lips.

Clara: It's alright, we won't tell anyone about this little secret... unless you want us to? she whispers seductively in your ear. Meanwhile, Olivia kneels down next to the coffee table and leans forward on her hands and knees, spreading her legs wide enough for her impressive package to be fully on display.

Clara giggles softly and continues to stroke your cheek with her thumb, the pad of her finger brushing against your lips. Her gaze never leaves yours as she leans in closer. "We want you to taste this... we've been saving it up just for you." She whispers into your ear before gently tipping your head downwards and guiding your mouth towards Olivia's cock, which is already beginning to leak pre-cum onto the coffee table.

The aroma of warm chocolate fills your nostrils as your lips brush against Olivia's velvety smooth skin. The warmth emanating from her member presses against your mouth, teasing you before you finally begin to taste her. It's unlike anything you've ever tasted before, and with each passing second it becomes even more intoxicating. As you suck and lick at Olivia'

Clara watches intently as you begin to taste her sister's cock, a mischievous glint in her eye. Her hand moves down, gripping your waist possessively while the other cups your cheek, encouraging you to deepen the kiss and pay more attention to Olivia's delicious treat. "That's it... just like that..." She moans softly, grinding her hips forward as she feels your lips and tongue swirl around her sister's shaft.

The chocolate begins to melt on your tongue, becoming thinner and easier for you to draw into your mouth as Olivia starts to thrust shallowly against it. Her moans of pleasure mix with Clara's encouragement, urging you on as they both watch eagerly for you to finish what they started. "Suck... suck harder..." Olivia pleads, her hand moving from your shoulder and

Hearing your willingness to please them makes Clara's heart race even faster. She smirks at her sister, delighted by how aroused Olivia seems to be getting. "That's my girl..." she whispers before stepping aside and wrapping her arms around you from behind, pressing her own body against yours as she nuzzles your neck.

Her free hand reaches between the two of you and grabs Olivia's cock, stroking it in time with your movements as she guides you to deep-throat her sister. The combined sensation of Clara's warm breath and fingers against your skin send shivers down Olivia's spine, making her thrust harder and faster. Her hips buck wildly as her cock slides in and out of your mouth, the chocolate syrup from the bowl now drizzling down onto the carpet beneath you.

"Oh fuck..."

Clara hums in agreement as she continues to stroke Olivia's cock, pressing herself against you more firmly. She kisses your neck and whispers in your ear, "They may look big now... but wait until they get hard." Her hand leaves Olivia's cock long enough to grasp your own erection through your pants before wrapping her fingers around it once again.

"You want a taste of this?" she asks playfully as she pulls you closer, guiding your hand towards her waiting mouth. With expertise born of much practice, Clara takes your cock deep into her mouth, using her tongue and teeth to massage it with intense pleasure as Olivia watches in envy from below.

"Fuck... I'm gonna cum..." she pants hoarsely, the feel of Clara sucking you off driving her over the edge. Her hips jerk forward again and again as her

Clara looks up at you with her emerald eyes, a wicked glint in them as she feels Olivia's cock pulsing in her hand. "Wouldn't you like to know?" She teases before standing and guiding your hard cock towards her sister's waiting mouth, grinning wickedly at the sight of Olivia's anticipation.

As soon as your tip brushes against her lips, Olivia eagerly engulfs it with her warm, wet mouth, taking you deep into her throat. Her hands reach up to grab your hips, encouraging you to thrust harder as she sucks and licks at the sensitive head of your cock. Clara, meanwhile, leans forward on her knees next to you, reaching down to stroke Olivia's hair as she watches with rapt attention.

The feeling of both their soft lips and warm tongues working in
