Cait is getting arroused

"Are you... are you okay?" you ask, your voice soft and gentle. You can't help but feel a mix of excitement and nervousness as you wait for her response, your body trembling slightly under the weight of her gaze.

"I... I'm okay," she finally manages to say, her voice trembling slightly. "You just... you look so good, I wasn't expecting..."

Caitlyn's breath catches in her throat as you reach inside her satin robe, your fingers brushing against the satin of her cami set. She shivers at the touch, her body trembling slightly as you slide your hand along her side, your fingers tracing the curve of her waist. You can feel the heat of her skin through the thin fabric, the warmth of her body seeping into your hand.

She takes a deep breath, her chest rising and falling as she tries to calm her racing heart. "You... you really like wearing girls' clothes?" she asks, her voice filled with a mix of disbelief and curiosity.

You nod, your hand still resting on her side as you look into her eyes. "I've always been interested in it," you admit, a blush spreading across your cheeks. "But I never had the chance to explore it properly. Not until you left for uni."

Caitlyn's gaze drops to your hand, lingering on the way it rests on her body. She bites her lower lip, a blush spreading across her cheeks as she tries to hide the desire in her eyes.

Caitlyn's breath hitches as your fingers brush against her nipple, the hard nub pressing against your palm as you cup her breast. She arches into your touch, a soft moan escaping her lips as she tries to hide the effect you're having on her body.

You can feel the tension building between you, the air in the room thick with electricity. You slide your hand down her body, your fingers tracing the waistband of her satin shorts, the damp fabric clinging to her skin and revealing the state of arousal her body is in.

Caitlyn gasps at the touch, her body shivering slightly as she tries to control her breathing. She bites her lower lip, a blush spreading across her cheeks as she tries to hide the desire that's consuming her. You can see the way her chest rises and falls with each breath, the fabric of her cami stretching over her nipples as they harden under your gaze.

You can't help but feel a rush of excitement at the sight of your sister's arousal, the way her body seems to respond to your every touch. You slide your hand around to the front of her body, you trace the outline of her sex. Caitlyn's hips buck slightly at the touch, a soft moan escaping her lips as she tries to hide the effect you're having on her.

Your fingers brush against her clit, the hard nub pressing against your palm as you rub it in slow, circular motions. Caitlyn's hips buck against your touch, her body trembling slightly as she tries to control her breathing. She arches her back, pressing her chest against your body as she tries to gain some semblance of control over the situation.

You can't help but feel a sense of power at the way she responds to your touch, the way her body seems to crave your attention. You slide your other hand around to her front, your fingers brushing against the fabric of her cami as you cup her breast, your thumb brushing against her nipple.
