“I think we’re all alone down here.” The energy was different even before she said that upon recognizing it as well, but it certainly dialed it up.
“Yeah, I think we are.” It was a slow song, my hand was already half on her big butt. It wasn’t crossing a huge line to let it slide down more, till I was full on groping it.
“Just because we’re alone it gives you permission to do that?” Since we stood more or less right under the laser globe there was always some light on us, of one color or another. So I could see her smirk in our lonely world of mist. “My husband wouldn’t like that.”
“He wouldn’t have liked how you were rubbing it up against my cock earlier either.” We’d had this teasing conversation once already, only I hadn’t said what she’d been rubbing against.
“No, he wouldn’t. Especially not since I got it ard.” I didn’t correct her, it had certainly stiffened up, I mean that fucking dress had rolled up and I’d been rubbing my thin green material (sans underwear) covered crotch right up against her black panties. “He really wouldn’t like it because it was bigger than his.”
I wanted to tell her that I wasn’t even half hard yet either, but that felt petty. Plus she was stroking my biceps, tracing my pecs, and already seemed impressed enough. Her smile brightened when the slow song ended, a much bassier club song beginning. We immediately shifted into it. Touching each other, rubbing against each other, really no differently than we had when my wife and everyone was else was nearby. Until there came “drop it low” part to the song, and my wife’s brother’s wife dropped it low. Coming back up, the dress a bit higher from how she’d squatted to get so low. Only instead of black panties covering the inner part of her peeking butt, there was just pale flesh.
She did blush when she saw me seeing it. I don’t think she’d intended it as a sexy seduction thing. It was warm down here, despite the lateness of the year. Warmer after so much dancing. Maybe she had but just got a hiccup of worry from her boldness. Either way after the moments of us realization, I pulled it the rest of the way up.
I shouldn’t have. I know. I should have been more subtle or seductive about it, but I couldn’t help myself. I was buzzing pretty hard, even more ‘drunk’ on the kinkiness of dancing all night with my married sexy sister in law. While she bit her bottom lip, knowing this was wrong and stupid, she didn’t fix it. Just kept dancing up against me.
Thirty seconds later she was facing me, since she was shorter she wasn’t rubbing her pussy right to my cock but she was trying. Trying while running her hands down the back of my Robin tights,double cupping my ass. Using it for leverage to pull me against her bare pussy. One that was covered sparsely in blond brown hair, like she’d had it shaved a couple weeks ago and hadn’t gotten around to it lately. Blue eyes locked on mine as she felt me growing harder in the thin covering of my tights, her pretty face changing colors in the light globe.
