Todd has some questions

Whilst Todd sits there a moment to catch his breath and you sit opposite him pondering what comes next, Mia takes this opportunity to use her fingers to lick up every drop of cum that coats her face as best she can. It's a mix of yours and Todd's at this point and who knows which parts came from which of you. Todd looks on in both disgust and arousal as Mia commits this depraved act which you've become so accustomed to.

Once Mia's done she crawls over to your side of the desk and kneels at your side.

Todd, finally having caught his breath after an intense fuck, takes this moment to ask what just happened.

"So, you want to explain what the fuck is going on?"

"I suppose now would be a good time."

"You're damn right it is." Todd replies fervently

"Well it all started a few months ago when Tracy and I were talking about what kind of things we're into in the bedroom, you know, normal couple stuff. Turns out she's a bit of a nymphomaniac and loves the idea of just getting fucked as much as possible by whomever's cocks she can get her greedy little hands on. Anyway, ever since then we've been kind of exploring that and things have taken a turn for the more taboo."

"So you're into... cuckolding?" Todd asks hesitantly.

"Not exactly. With cuckolding I'd be watching her getting fucked by other guys without taking part. In our case, it's more like I'm her master and she fucks whoever I tell her to, and luckily for her I like to share."

"I see... And so you've decided to bring her into work because you guys weren't already having enough sex at home?"

You chuckle realising what you now have to explain. "Well not exactly. See, this isn't actually Tracy."

"Then who is it." Todd asks hastily, looking at Mia now confused as to who he's just fucked.

"This is Mia, Tracy's twin sister. Or as I now call her, Whore."

Todd stares back at you, perplexed. His eyes glance over Mia repeatedly, trying to find any sign that he should've noticed earlier, indicating that this was not in fact Tracy who he had met multiple times in the past.
