Just at the wrong time the door to the men's room swooshes open. Not now! I'm right there... Right there! I grit my teeth and freeze, keeping very still. The stall door two cubicles down squawks on its hinges and the metallic jangle of a belt buckle sounds loud in the silence. I can feel you tense beneath me, your manhood hugely swollen in my steaming sheath. As silently as I can, I pull my legs up so that they won't be visible beneath the partition. It's difficult to balance on your lap that way, straddling your hips as I face you. I suppress a giggle. You give a warning frown and shake your head. Quiet, Sara. 

Of course he would have to use the toilet instead of a urinal. "Hurry up!" I shout silently. I was seconds away - seconds! And now this interruption. You wiggle slightly inside me, striving to maintain your arousal, and I respond by contracting my pelvic muscles rhythmically. S-q-u-e-e-e-z-z-e--e release. S-q-u-e-e-e-z-z-e--e release.

You moan quietly, but it seems to echo from the tiled walls. Sh!

The man sits silently for a bit, no doubt hoping that you are nearly through and will leave him in private. But after a moment he sighs and there are.... sounds. OMG! This is SO EMBARRASSING. 

Embarrassing - but exciting as well. Sara, you are so sick. I squeeze harder and wiggle my nubbin just the slightest bit on your pubic bone. Oh God, I'm sooooo horny! If I could move just a little.... just the slightest amount....

Your hands on my hips clench with fingers of iron and you shoot me a warning glance. But not before I feel your phallus twitch and pulse within me. Oh, yes! You're close, too, Chris! I bend to meet your lips in a silent kiss, the slight rocking of my pelvis sending electric shocks up my spine.

The bathroom door opens again. We freeze. A pee-er this time. Oh my God, I can hear him tinkle. This is so gross! But a fresh surge of moisture between my legs betrays my excitement.

I squeeze you faster now, with abandon. You grunt into my mouth and your fingers move to my bottom, cupping my cheeks. Oh! If I squeeze just SO, it feels marvelous! I am so close.

The urinal flushes and there are footsteps to the sink. Splashing water covers the quick thrusts of my pelvis as I grind down on you. So CLOOOOSSSSEEEEE.....

The water stops but the guy at the sink is still there. We freeze again. Has he heard something? The man two cubicles down noisily unrolls some toilet paper. An earthy odor penetrates our space and I wrinkle my nose.

I am so close that I throb. I look at you beseechingly and can see the agony in your own face. If we could have just a few seconds alone....

And the bathroom door opens again. Another visitor. I hear him unzip and in a moment the sound of his stream hissing into the urinal. I... I.... can't hold back anymore. I grit my teeth and try to hold down the climax building inexorably within me. Hold it back... Hold it b-a-a-a-c-k....

And then your finger brushes my anus and I EXPLODE! I tremble and shake, in the grip of the strongest orgasm I've ever had... trying, trying to be silent... And just as the contractions start to ease, you make one mighty thrust deep inside me and I feel the warm wetness spurting and it drives me over the edge again. We cling to each other and convulse. A single grunt escapes your lips. Your finger continues to tease my bottom and I peak again and again, until, spent, we silently slump.

The urinal and toilet flush in quick succession and the occupants wash up and leave. I hear them laugh knowingly as they go out the door. Oh, God, I am so embarrassed!

"Let's do it again!" you whisper, and I reach around behind me to tickle your balls.
