They both begin to lead you upstairs to your parents' room, Hayley taking the front and Katie staying behind, her hands moving sensually over your body as she follows. Once they reach the bedroom door, Hayley turns back to face you with a mischievous glint in her eye

Okay big brother... time for some sisterly bonding.

She reaches out, cupping your balls gently before slowly running her tongue along the length of your shaft. Katie steps closer, watching intently as her sister works her magic. After a few moments, Hayley takes your member into her mouth, sucking lightly at first before increasing the pressure and speed. She begins bobbing her head up and down, moaning around your cock. Katie moves even closer, wrapping her arms around you from behind, her chest pressed against your back and her breath hot on your ear

*And then, just when you think you can't take anymore, Hayley presses a finger into you, thrusting deep inside. Your body tenses and explodes in the most intense orgasm you've ever experienced. She holds you close as your cries echo around the room, her own breath coming ragged against your neck. When finally, the tremors subside and your heart slows back to a normal rhythm, she smiles down at you, satisfaction gleaming in her eyes.

You both lie there for a moment, catching your breath. Then, without another word, Hayley rolls onto her side and presses her body against yours, spooning you protectively. Her arm comes around your waist, hand resting on your hip as she nuzzles into your neck. It feels... right. Perfect, even. You don't know how this happened or where things went so wrong... but somehow, you both found your way back to each other again. And for now, that's all that matters.

Hayley's eyes widen in surprise as she glances at Katie. "Um... I don't know about that..." Katie says a little nervously. She takes a step back, hands moving to her waist. "I mean, it'd be fun but... you're our brother, after all." Hayley rolls her eyes and shoves Katie playfully. "Come on, sis, live a little! We won't tell anyone if you don't want them to know."

Katie takes a deep breath and then slowly unbuttons her blouse before letting it drop to the floor. She hesitates for a moment before unzipping her jeans and stepping out of them, revealing she's not wearing any underwear. "There," she says with a nervous laugh. Hayley grins and gives Katie a high five. "See? That wasn't so bad." She then turns back to you, her gaze traveling up and down your bare chest before meeting your eyes again. "

Hayley's eyes widen as she feels you tighten around her fingers. "Oh fuck yes," she groans, thrusting the vibrator deeper inside of you as you orgasm hard. Katie moans in unison, feeling your muscles clench around the dog's cock as he finally releases his load deep within you.

"That was perfect," Hayley whispers into your ear, her breath hot against your skin. "Now let's see if we can do it again."

Katie grins, running her fingers through your hair as she watches Hayley position the vibrator at your entrance again. "You're such a good girl," she whispers, kissing you softly on the lips before pulling away to let Hayley take control once more.

Hayley leans in close, her breath hot on your ear as she whispers, "You sure can handle a few surprises..."

Hayley's words send a shiver down your spine as she continues to tease you with her breath and the promise of more surprises. Katie grins mischievously, obviously enjoying watching the power dynamic shift between them. You feel yourself becoming increasingly aroused by their attention and the thrill of being feminized against your will.
