Don't watch

Things have happened, but that doesn’t change the fact that peeping at your sister might not be the classiest thing to do. With a huge effort, you quietly move away, although it’s already getting to you, and that makes it hard to tiptoe.

Nadia yanks you into her room so suddenly that your heart stops for a second, then you wince as the sudden movement tortures your trapped erection.

She closes her door and glares. Nadia wears one of her creamy work blouses, unbuttoned, and a nice white bra and nothing else. She’s a sweaty, disheveled mess, and she holds a purple dildo that would be funny if you didn’t feel like you’re about to pass out from need. It looks like Nadia’s been caught in the same trap that you have.

“Those fucking dipshits,” she grinds out as she unbuckles your belt.

“They probably thought they had the place to themselves,” you say breathlessly, pulling her close. She shivers as you squeeze her ass.

“I’m allowed to come home for lunch,” she grumbles. “That’s allowed.”

You don’t argue with her; she has your cock out. You slip your hand between her legs. She’s neat down there, boiling hot, and soaked. Her thighs are coated.

You’re both breathing hard and feeling good. She looks up at you, then hurriedly looks away, her hand motions getting a little jerky and inconsiderate. She’s trying to get back to work, so you just rub the fastest circle around her hood that you can. But it’s too much, too fast. She hisses and grabs onto you, looking up again. She’s flushed, and her mouth is open.

She seems to come to her senses and looks pissed, stubbornly turning away again. She’s so wet that your hand slips, and you can’t help yourself. You slide two fingers inside effortlessly. She stiffens and clenches at you. Her fingers squeeze your dick.

This gallant attempt you’re both making at a businesslike mutual isn’t going to work. You roughly turn her around and bend her over the dresser.

“Oh my god, yes,” she says, the words so low that they’re almost lost under her breath. You slip in and move deliberately. The last traces of self-awareness that you have are dedicated to not going all out, because you could pound her, and she would scream, and Rey and Delilah would hear it all. And when she comes to her senses, Nadia won’t like that. She’ll like it right now, but she’ll be upset later.

Your hands are on her hips. One goes to her shoulder for leverage. She bites her hand. She’s so wet that you’re gliding in and out like its nothing, and she is so hot inside that it feels like you should be getting burned.

She looks over her shoulder, mouth wide open. You pull her upright and put your arms around her, thrusting up into her vigorously. She whimpers, and you smell her hair. Her arms are pinned, and her body is all but immobilized. Only her head can move, and she keeps turning back, as though there’s something she wants to check on or say. Her mouth begs for a kiss, and you have no control. When your lips touch hers, her insides lock down vengefully. You can’t hold back your moan as you empty yourself inside her.

The kiss only breaks when your spent bodies naturally lean together on the dresser, still fused together. You take deep breaths while her pussy flutters around your softening cock. The delay between each ragged breath steadily gets longer until you finally find the strength to step away.

Cum drips down her red, wet thighs. A condom never even entered your mind in that ambush.

You stiffen when she looks over her shoulder, but she doesn’t look mad. She looks pleased. That might be worse. You hurriedly zip up and leave.
