The girls have their lunch

"Alright girls, it's lunch time." You say, starting to unlock Tracy's cuffs before stepping into the next cubicle to do the same for Mia.

"What will we be having?" Mia giggles playfully.

"What would you like whore?" You reply with a smile.

"I think you know sir." She says with a devilish grin.

"I want to hear you say it." You cruelly add.

"Fine, if you're really going to make me say it. I want to drink all the delicious cum from all the men who fucked me." She blurts out, perhaps a little ashamed to be saying it in front of Todd, a man who was a stranger to her yesterday.

"Very well, you can have the one's on your body and the floor, but leave the one's attached to your outfit. I like how they look." You say.

"Thank you sir!" She shouts with excitement.

Still lying on their backs on the toilets whilst recovering, the twins start picking up each of the condoms scattered across their bodies and squeezing out every drop of cum from them into their mouths, before greedily gulping them down as if they were the tastiest treat they'd ever had (which it probably was to them).

"That's just fucked up." Todd says next to you.

The girls glance at him a moment as he speaks before looking down in shame as they complete their filthy task which is as much a reward to them as getting to finally cum. Despite his comment, Todd still looks on as the girls perform this depraved act, staring with a look of arousal.

Once the girls have finished cleaning up their bodies and faces, they get down onto their hands and knees on the floor and pick up each of the condoms on the floor, doing the same with them. Once they've emptied each of the condoms into their mouths, they lick up any drops that were spilt earlier in the day or during their meal.

"Tell me, did any of the guys follow the sign and piss in your mouths?" You ask.

"No sir, I think they were too shy to." Tracy replies.

"Hmm, we'll have to do something about that too." You say, grabbing the sharpie and changing the signs a little.

You cross out some words and replace them to emphasise your point. The sign now reads:

Mouth = $0
Pussy = $0
Ass = $0
Please use a condom.
Regards, management

P.S. PLEASE piss in my mouth, I'm REALLY thirsty

"That should do it." You say. "In the meantime though, open your mouth up for me." You say to Tracy.

Tracy kneels at your feet and opens her mouth up wide. You point your cock directly at her mouth and release a strong stream of piss, not having gone yet this morning.

Tracy purposefully lets some drop onto her chest as she gulps it down in order to put on a show for you. You know she's doing this on purpose because she's become far too good of a piss drinking slut to let any spill out from just one guy at a time.

Todd, looking on as you do this, decides to silently follow suit and goes into Mia's cubicle and gives her a thirst quenching drink too.

With the girls now fully serviced, you set them back up as they were before, locked in position on each of their toilets with a ring gag in each of their mouths. As you're doing so, you notice that the boxes of condoms are just about to run out, turns out you had one horny workforce. With no other option, you simply shrug your shoulders and cross out the line about using a condom. Good thing they were both on birth control.
