It’s little Tom's birthday and you’re helping with the birthday preparations. You’re in the kitchen helping out with some of the refreshments. In the other room are Emmet’s little friends as well as family and friends. As you’re putting things on plates and getting the party ready. You’re getting flirty with the mistress as you both dressed up, she’s looking very distinguished as the hostess.You start to purposefully drop things slowly pick it up, showing off your ass. You suggest you need a spanking but playfully remind the mistress she can’t in case it makes a noise and everyone at the party comes into the kitchen. You drop something else and before you can pick it up, your wrists have been grabbed and you're handcuffed with your hands behind you. You’re pushed into the sink and realise you're helpless now. Mistress gropes you viciously, she exposes your breasts and she starts to finger you. You’re both shocked and exhilarated by how cruel she’s being. You bit your lip to avoid making a noise for the party goers. Your edged hard and ask for permission to cum. You’re refused and asl why you haven’t been given permission, the mistress puts on a strapon. It turns out the mistress is horny and wants to punish you due your ass related teasing. You’re ordered to suck it and you oblige. You suck it, making it wet, in between gasps for breath, you beg to be fucked. Eventually you’re ordered to stand up and turn around, you lean against the sink and get on your tip toes and mistress starts fucking you. You’re getting off from this bout of degrading sex but she stops. The Master has walked in and Mistress is needed in the other room as someone needs to speak to her. Mistress leaves and Master takes a good look at you. You dance around and offer yourself as sloppy seconds and he’s happy to take advantage as he doesn’t need to do any forplay.You bend over and he starts fucking you. As he fucks you, you talk dirty to him... how you’ve had sex with two different people in a matter of minutes and how it’s with a married couple. You think you’re about to cum as Mistress walks in. Master stops fucking you. You’re ordered to your knees to apologise for being shameless as it turns out you were making a noise. Things aren’t helped as Master and Mistress both want to penetrate you. You’re going to be punished and you’re worried about what that means. You’re ordered to ride on Master’s cock and the two of you fuck but you feel something entering you from behind, Mistress is fucking your ass.You’re being subjected to your first double penetration, with you being close to cuming a few times already, you’re struggling to keep your composure, now you know what you’re punishment is. All of you are close to cuming, you’re finally granted permission and you cum hard from both of your holes. As you catch your breath, you acknowledge how Mistress has truly used you. However it’s not completely over yet. Someone needs to bring the cake into the other room and you’re ordered to it. You take the cake and do a walk of shame, as you walk awkwardly to avoid leaking and flowing cum and other juices to any party goers.
