Of course you're staying

The thought of giving Lucy and her new friend privacy hardly even enters your head. You stand just outside the stall, straining to hear their soft moans and dirty talk over the muted music from the bar. You watch the man's bum tensing with each thrust as he puts it to your friend, his cock audibly sloshing into her cum-stuffed cunt.

"That's it," he groans, his hips slapping against her ass. "Almighty are you hot down there."

"Faster," Lucy replies and her new lover obliges, slamming in and out of her with increasing intensity. He takes firm hold of her hips and slaps into her again and again. The sight, sound and even the smell of sex is driving you wild. As you watch their filthy display your hand wanders your waist. You slip your fingers into your panties and feel your wetness gathering against your mound.

Lucy's friend leans over her, hunching above her back in deep, steady strokes. He reaches beneath her and gets at her tits, squeezing them roughly and tugging on her fleshy nipples. Lucy sighs with pleasure, tilting her head back and leaning into him. You slip your fingers over your slit and tease the hard bud of your clit. You glance over at Karen. She's not being as obvious as you, but she's rubbing herself through her clothes.

"I'm close, love." The man grunts, stabbing his cock into her with deliberate ****.

"Well don't stop now, I'm just getting up a head of steam," she arches her back and twists her neck to offer him her lips. They kiss and their sordid intensity drives you wild. You diddle your clit and slip a finger into your boiling depths.

"Not yet," Lucy hisses through clenched teeth. "Not yet. Not yet. Ahhhhh!"

Her wail of orgasm seems to slice through the dulled noise of the music. It's so shrill it sends a jolt through your body, triggering a chain reaction in you like a yawn. Your knees go all weak and you sag against the post of the stall, desperately fingering yourself through an orgasm so intense you see white flashes. You work your hips, fucking fingers, too absorbed in your own pleasure to even remember what is happening.

As you recover you are aware that Lucy's impromptu lover is plunging over the brink himself.

"Fuck," he groans. "Going to...ahhh...ahhhhhhh!"

He thrusts roughly into her several more times, his motions awkard and intense, his bum flexed as he buries himself in her and unloads.

"Ah," Karen softly cries, apparently cumming herself.

After a few seconds of breathless chuckling the man drags his engorged cock from Lucy's depths. You get another look at her hairless quim, now a bit raw and dripping with fresh spunk and the frothy slop of the previous man's load. It's a raunchy sight and Lucy does nothing to hide herself as cum oozes down her thighs.

The man, stumbling drunk, is suddenly bashful. He stuffs his cock away and, nodding with embarrassment, backs out of the stall.

"Awwww," Lucy calls out of him, her face flushed and sweaty, "Not going to stay for a cuddle?"

"T-thanks," he says and exits the bathroom with a burst of loud music.

Lucy looks to you and Karen, but remains leaned forward, her dripping pussy and pale ass exposed to you. Before you can speak to one another the door opens once again.

"Well, well," says a deep man's voice. You look and see that it is Clive, the bar's stout, strapping owner. He's middle-aged, but well-dressed and not terrible to look at. He has seen you and Karen, but hasn't had a look at Lucy yet. "What are you two lovelies doing in the lad's room?"

Is Lucy up for a third or is it your turn to take on a man?
