Remember when Mistress said that she was going to give you a threesome for being such a good slave? Well today's the day, but it does come with a twist.
Oh yes, I've got one of my hot girlfriends over and we're going to make sure that you love every second of the action that unfolds here today. See, we've known for a while that you love the idea of being pegged, which is why I brought along this big plastic cock that I'm going to fuck you in the ass with.
There's no point denying it: you're hungry for the dick, and that's okay. Here, how about you open that mouth of yours so I can shove this in and give you a good hole full of pleasure. Spit in this dildo with everything you've got, because you're about to get pegged in the ass with it like the submissive slut you are.
