Setting up the twins

The four of you head to the one large mens bathroom for your office building. Your company has the whole small office building to yourselves meaning there won't be any outsiders stumbling across the girls, not that it would matter.

The bathroom has a long row of 7 stalls opposite the sinks. You lead the way to the far stalls where you drop your bag and open it up to get at its contents.

"Drop the trench coats girls."

"Yes sir." "Yes daddy" They reply in unison.

The moment they drop their trench coats to reveal their outfits Todd's jaw hits the floor, admiring the girls in their sexy outfits.

"Goddamn. You two are something else."

The girls giggle and each reply with a "Thanks Todd."

"Alright now each of you take a seat in these two stalls."

The girls step into the last two toilet stalls and take a seat on the closed toilet lid. With them in position you first go to Tracy's stall to set her up. First you handcuff her hands behind her back, so the cuffs run behind the toilet and lock her into position, preventing her from being able to get up. Next you take two sets of cuffs and lock each of her ankles to the two side rails in the stall. This leaves her seated leaning back on the toilet, with her hands locked behind her and her legs spread wide in the air, a very inviting position to anyone who happens upon her. You instruct Todd to do the same for Mia whilst you get more supplies out of your bag. In this position both their pussy and their asshole is exposed and pointed forward to whomever walks into the stall.

Next is a pair of ring gags which you put into each of their mouths to keep them open wide and prevent them from talking at the same time.

"You ready for this?" You ask your once innocent girlfriend.

"Yes sir. I can't wait." She says eagerly.

"Good girl." You say before slipping the ring gag into place.

It's nice and wide, allowing plenty of space for a cock to slide on through and fuck her throat. How comfortable it is for Tracy's jaw is a whole different story, but this slut's comfort isn't what's important. She won't be complaining the moment she gets a cock in her.

Next you leave a big box of condoms on top of both of the toilets that they're seated on. Finally you add the finishing touch, a pair of signs stuck to the wall above each of them with instructions.

The signs read:
Mouth = $0
Pussy = $0
Ass = $0
Please use a condom.
Regards, management

P.S. Feel free to piss in my mouth, I'm probably thirsty

You take a step back to where you can see both of them set up in their stalls and admire your work. You step into each of their stalls to make the final adjustment, pulling their thongs to the side to expose their eager holes. Upon doing so, you can see that both of them are already dripping with excitement.

"Shall we give them a test drive?" You ask Todd
