"Did you know there's an upstairs to this place?" I whispered into her ear, leaning in from behind as we stood at the bar, waiting.
"Yeah. And it's quiet. And dark."
"That's interesting. What do you want to drink?"
"You know exactly what I want. You know where the elevator is?"
She nodded with a vague smile.
"Up the stairs behind. I'll wait around the corner."
"Sure you don't want a drink?"
I nibbled at her earlobe in response, sliding my hand down her back. I could feel the shape of her thong through the soft fabric of the turquoise dress.
Upstairs was indeed quite dark. A disused small hall, with stacks of chairs lining the short corridor leading to a small alcove and a locked double door. The carpeting was old-fashioned, dull and thick, great for dampening any noise.
I didn't hear her come up the stairs until she was almost at the top.
"So, what do you want to show me?"
"Oh, it's good," I whispered, taking her hand and leading her into the shadowy half-privacy of the alcove. I pulled her to me, up against the wall for a kiss, and she leaned back, resisting.
"Don't... my makeup."
"Yeah?" I kissed her neck. "You sure about that?" I slid my thigh in between her legs, and pushed her skirt up a little. She sighed very quietly, and pressed her crotch against me.
"I'm relying on your generosity." I pressed her hand against the hard bulge on the front of my trousers.
"Mmmhmm... yes, but I'm definitely going to want some later."
"You will get anything you wish for, darling. Now, down on your knees."
She slid to the floor in front of me and started unbuttoning.
"Good." She reached in and pulled my cock out, looking at it for a moment. Her freshly-glossed lips glistened in the half-dark when she opened her mouth.
She took it in as far as she could, immediately. I gasped when the tip of my cock hit her tongue, wiggling against the underside.
"Be quiet," she glanced up at me, then swallowed my cock again, grasping the base with her hand.
This was not some teasing, foreplay blowjob. It was a serious assault on my hard, throbbing cock, intended to make me come as fast possible before anyone found out what we were up to, and motivated by a combination of lust, anxiety, exhibitionism, and greed for the hot cum I was about to fill her mouth with.
She likes it. The stolen moment, the hiding, the lustfully ungracious and crude speed of the blowjob. And she went for it.
My heart was beating, I knew we didn't have much time until someone noticed. Worse, if someone might wander up there looking for a quiet spot of their own...
Speeding up, she sucked with even more force, her cheeks tightening around me.
Very quietly. I came, fucking her mouth, holding her head still, enjoying the sense of using her for my selfish pleasure. The slurping sound seemed rudely loud in the quiet of the upstairs. She swallowed, and we stayed still, listening if any unwelcome ears were lurking around the corner.
She wiped her lips against he sides of my softening cock, and I helped her to her feet.
"Careful," she whispered, giggling, "don't get cumstains on my dress. How do I look?"
"Not like a woman who just gave a fantastic blowjob."
"Thank you." She kissed me, our tongues intertwining, not giving a shit about the lipstick. It was all gone.
Wobbling slightly on her heels, she turned around. "See you in a bit."
I put my cock back and buttoned my fly. Waited for a respectable few minutes. Someone might guess what we'd been up to, but there was no reason to make it easy for them.
