Excerpt from document titled Santana hears Rachel touching herself and gets horrifyingly turned on.

ETA: This is now a full length fic and can be found here.

It totally shouldn’t be turning her on. It’s Rachel, for fuck’s sake and, yeah, they kinda might be friends now, but that doesn’t mean she actually wants to go there.

The thing is, she can’t exactly deny the growing arousal that’s starting to build in her body and, if she actually dares to move, she knows she’s gonna find her panties are soaked.

Rachel lets out this tiny, breathy little moan and Santana feels herself fucking clench in response. It’s so quiet that she can hear the soft, wet noises coming from across the room as Rachel works herself higher and higher. Santana’s fingers twitch by her thigh as she fights the urge to move them. The thought of Rachel knowing she’s awake is embarrassing as fuck just on its own. Being caught with her hands in her panties, getting off to the sound of Rachel getting off is just—no fucking way.

She’s too hot; her skin is prickling under the covers and she can feel beads of sweat starting to gather on her body. She wants nothing more than to throw off the bed covers off and maybe go take a cold shower or something, but she just bites her lip and hopes to God that Rachel finishes soon.

It seems like her prayer may be answered because Rachel’s breathing is getting faster, heavier, and the rustle of fabric sounds a little more urgent. Santana dares to move her head slightly then immediately has to clamp her teeth down harder on her bottom lip to stifle the moan that tries to escape. She can see Rachel outlined by the soft light coming in through the hotel’s window. Her eyes are closed and her mouth’s parted as she takes in sharp breaths. One of her legs is raised, the one furthest from Santana, so she can see the bulge of Rachel’s hand underneath the thin sheet covering her body. It’s moving quickly and Santana bites back another moan as she imagines crossing the room and replacing Rachel’s fingers with her own; sliding them through the heated flesh between Rachel’s thigh, maybe dipping down and tasting her.

Before Santana can act on what would probably be a really fucking stupid idea, there’s a soft gasp and Rachel’s body stiffens momentarily before shaking with her orgasm and Santana feels her own body shudder in sympathy. After a few seconds, Rachel lets out a small sigh and then everything’s still for a little while until she turns over in her bed and appears to settle down for sleep.

A few minutes later, Santana hears quiet snores coming from Rachel’s direction and at that, her control snaps. She slides her fingers under the elastic of her panties and sighs in relief as they slip through the gathered wetness. It only takes a few passes over her clit and a rough twist of her nipple until she’s coming with a hiss and a muttered fuck. She pulls her fingers back, wiping them clean, then twists herself up in the sheets and tries for sleep.
