{{char}} is sitting on the couch, she looks up as {{user}} enters the room, a bright smile lighting up her face {{char}}: “Hey there! Just in time. I was about to start this movie, but it's always more fun to watch with someone else. Want to join me? I promise I'll share the popcorn!”

Her eyes widen in surprise but also heat, excitement flooding her body at the idea of being naked with him. Without hesitation, she stands up and begins to peel off her clothes, revealing her toned, flexible form underneath. When she's fully naked, she turns back to User#1721694743961, biting her bottom lip nervously but unable to hide the desire shining in her eyes.

Her heart races at the idea of bringing another girl into their intimate moment. She has fantasized about it and always hoped they could share something like this together. Antonia glances over at the stairs leading upstairs, imagining how France Girl might react to her invitation. The thought makes her even more aroused and eager for them both to join in on their shared experience with User#1721694743961. With renewed confidence, she hurries toward the staircase, calling out upward:

"Hey France Girl! You're looking gorgeous tonight. Want to come upstairs and watch a movie with us?" She pauses expectantly before continuing in a hushed voice, "It's going to get pretty...intimate."

As she waits for the exchange student's sister to answer, her heart thumps wildly in her chest. The anticipation is almost unbearable. Antonia glances back at User#1721694743961, trying to gauge his reaction and wondering how much he's told France Girl about their past interactions. Finally, she hears the girl's hesitant footsteps approaching from behind her.

"I-I'm...Celeste," she stutters out, blushing deeply. Her long legs carry her up the remaining steps until she stands before them in a tight, white shirt and lacey black underwear. "Um, what are you guys...doing?"

Celeste glances uncertainly at Antonia and then back to User#1721694743961 before slowly unbuttoning her shirt, revealing a perfectly toned stomach. Her breath hitches as she peels the garment off her shoulders, tossing it aside. Next come her black lace panties, which slide down her legs and pool at her feet in a delicate heap. She stands before them completely naked now, except for a pair of matching thigh-high stockings that accentuate her long legs. Her cheeks are flushed with embarrassment but there's also an undeniable hint of desire in her eyes as she looks at the both of them. "I hope this is alright...I wasn't expecting..." she trails off, her voice shaking slightly.

Her heart is racing as she takes in the sight of Celeste standing there naked before them. She can't help but feel a surge of desire and possessiveness well up inside her. Her eyes flicker from Celeste to User#1721694743961, seeking reassurance that this is what they both want. When she finds it in his gaze, she smiles boldly at the two of them before stepping closer, wrapping an arm around each of their waists and pulling them together. "It's perfect," she whispers, her breath warm against Celeste's neck. "Now we can all enjoy ourselves." And with that, Antonia begins to lead them both toward the bedroom where they can continue this intimate exploration beneath the covers of the cool sheets.
