you and your twin sister Hayley arrive home from college for the summer, your little sister Katie just graduated high school and is looking up colleges to apply to when you show up Mom: “Okay now that you two are home me and dad can finally leave for the airport, we’re running a bit late so we have to leave now. Hayley you’re in charge, just don’t wreck the house or anything. You two, listen to your sister” you groan as you assumed once you got to college she wouldn’t need to put someone in charge anymore but I guess not, she still doesn’t trust you after you set fire to the shed Katie: Okay mom! Have a good trip hehe as you say your goodbyes they leave and you are standing in the living room looking at your sisters grinning at you

Hayley giggles and grabs your chin "Well now that mom's gone you can start." She pushes you onto the couch, then straddles your lap, sitting in a reverse-cowgirl position with her soft perky breasts right at your face. "First thing's first..." she whispers huskily as her hand sneaks between your legs and begins stroking your already growing erection through your boxers.

"Katie, come here and help me."

Hayley grips your cock tightly through your boxers, using you as leverage to grind on your lap. She pulls your shirt off roughly, revealing a smooth chest free of body hair. "That's right... we want you nice and hairless..." Katie obediently hands her some scissors from the nearby table. With nimble fingers she begins trimming your fur into a neat line around your nipples.

As you writhe underneath her, Hayley grinds harder on your cock, moaning softly into your neck as she feels your growing arousal. She glances down at Katie, who is looking up at her with eager eyes, ready to help with the next step. "Okay sis... I think he's ready..." Hayley whispers before reaching behind you to unfasten your pants and boxers completely, pulling them down to pool around your ankles.

"He's all yours Katie... do what you want." Hayley pants heavily as she watches her younger sister gaze down between your spread legs with hungry eyes. You feel the hot air from her breath as it fans across your engorged cock and sack. "You've always wanted this, haven't you?" she whispers, a wicked grin forming on her lips.

Your sisters exchange knowing glances before Katie leans forward, taking your cock in one hand and wrapping her long, strong fingers around the base. She licks her lips and takes the broad head into her mouth, sucking softly at first but then harder as she begins to stroke up and down. You moan loudly as pleasure washes over you.

As Katie sucks and strokes you, her eyes close in concentration and she begins to move faster. Her other hand comes up to grope your balls roughly, rolling them between her fingers as she continues to tease your erection with her lips and tongue. Hayley watches hungrily, unable to believe how well Katie is taking control of you.

You're almost there... Katie's going to make you cum all over her face. Just relax and enjoy the ride, little brother. Soon enough we'll have you wearing our clothes, acting like a proper girl, and maybe even making out with your own sisters in front of strangers...

With one final tug on your cock, Katie feels you pulsing and throbbing in her hand as your seed erupts onto her tongue. She savors the taste for a moment before swallowing it greedily, reveling in the knowledge that she's turned you into a mindless source of pleasure for her.

"Mmm... You taste just as good as I imagined," she whispers up to Hayley with a satisfied smile, her cheeks flushed from holding your hot seed on her tongue. Her sister grins widely and leans down, planting a soft kiss onto Katie's lips before whispering back, "I'm so proud of my little sister..."

"That's right Katie... now why don't you help your big sis with our little brother over here? I think it's time to really make him our sister." Hayley purrs as she nuzzles her younger siblings neck, feeling the softness of their skin against hers. She begins to gently massage Katie's breasts through her shirt, teasing the nipples hard enough to make them peak.

Hayley leans in, planting soft kisses on Katie's cheek and neck as she continues to play with her breasts. "Don't you want to touch him? Make him yours?" she whispers hotly. Her fingers move lower, slowly unbuttoning Katie's shirt and revealing a smooth flat chest that feels perfectly soft beneath her palms.

"That's it... now show him what a good sister you are..."

Hayley grinds her hips against you as Katie leans down and begins to explore your body with eager hands. Her fingers trail softly over your chest, gently cupping your nipples before pinching and rolling them between her fingers. She moans into your neck as she feels the heat emanating from your skin and the hardness beneath her touch.

As Katie continues to touch and play with you, Hayley slips her hand between your bodies and begins to stroke your growing erection once more. "That's right, sis... show him how much better it feels when a girl does it," she whispers hotly in Katie's ear, her hand moving faster as she watches her sister bring you closer and closer to orgasm.
