Alyx looks down at you while leaning into your embrace. Her voice is soft but steady when she speaks. "Felicity needs someone who'll help her explore these feelings safely. And you're a good man, Fayt. You've always protected her." She pauses before adding, "I think we should let her join us tonight." Her hand rests on your thigh reassuringly.

Your sister stares at Alyx for a moment, clearly surprised by the offer. Felicity takes another deep breath, nodding slowly. "Thank you," she whispers, then turns to go, before adding one more request. "As long as I can masturbate while I watch, please."

Once she's left, Alyx slips out of bed to rummage through her bag. She comes back with a few toys and lubes, setting them on the nightstand. "We'll take care of her,"

You grin wickedly down at them both. "You like that, don't you?" Alyx nods, still working on Felicity's breast as she watches her sister respond to your touch. Felicity gasps when you slide a hand between her legs, finding her slick and ready for you.

"I want to feel you inside me," she whispers, lifting her hips toward yours. You grasp her hip with one hand and guide your cock to her entrance, pressing slowly inward until she's taken all of you.

Alyx leans in close, nibbling on Felicity's ear as you begin to move inside her sister. "Oh yeah," she breathes, "that's it." She trails her hand down between your bodies, finding Felicity's clit and starting a slow, teasing circle.

Felicity lets out a moan, arching her back as the sensations overwhelm her. You can feel how wet she is, how tight she's gripping you with every thrust. It's incredible.

Felicity glances between the two of you again, eyes growing wider with every passing second. She takes a step forward, hesitantly, her heart racing in her chest. "R-really?" she asks, her voice barely above a whisper. You can see the desire written all over her face, and for some reason, it's making you hard again.

Alyx gives you a sultry smile, moving closer to Felicity before speaking. "Of course," she says softly. "We wouldn't want you to miss out."

Alyx laughs softly into your ear before pulling back just enough to look Felicity in the eye. "Don't worry," she says with a grin, "I can be as freaky as you want me to." With that, she reaches out and takes Felicity's hand, leading her into the room.

You close the door behind them, not quite able to hide your excitement as you watch Alyx guide your sister onto the bed beside her.
