Stacey uses Olivia's throat

With a clear and cruel smirk, Stacey walks forward, her thick, hard dick pulling Olivia's attention as it get closer and closer to her face, looking like she is drooling at the sight. You can't help but feel even more aroused looking at the scene, Olivia still moaning from having your cock deep inside of her as you feel her tightness.

"Open wide, slut", Stacey commanded, and Olivia eagerly and quickly obeyed, opening her mouth in preparation. Not wasting a second, Stacey slammed her dick into her mouth, groaning as her **** started to eagerly suck and lick while at the same time slowly moving up and down on your cock, causing you to join in on the moaning. Looking down at her, Stacey grabbed Olivia's head by the hair, controlling her movements and forcing her to take her cock deep in her throat.

"Happy now, you cockslut? This is what naughty girls get when they try to use the marker without Mistress' permission", Stacey said as she continued, and from Olivia's face, she was absolutely loving every last second of what was being done to her. Deciding you want some more pleasure too, you grab her hips and start to **** her to move, to bounce on your cock at the same time as her mouth is being stuffed.

Now that you are much closer to her, you can see that Olivia's naked stomach is completely covered in words written with the marker, with varying degrees of quality in regards to the writing. The words that stand out to you the most are MASOCHIST, STACEY'S WHORE and TOTAL SUB, which go a long way in explaining the way she is acting, although you are still curious as to what happened before you arrive, which led to your roommate getting pounded and punished by Stacey and you.

Your groaning grows louder as you feel that you are reaching your climax, and the entire room is filled with the collective noises the three of you are making. It isn't long before you come, feeling immense pleasure as you do, and you are rewarded with Olivia's increased moaning as she goes limp. Grinning, Stacey pulls out and points her dick directly at Olivia's face, jacking herself off until she finally come, covering your roommate's face with her creamy cum. It is quite a sight to see Olivia like that, a dumb, blissful look on her face, with cum covering a considerable amount of it.

Finally done, Stacey picks Olivia up and throws her into the bed before turning back to look at you, still catching your breath. You look back up at her as she gets down and kisses you, groping your breasts and causing you to helplessly moan. It's a strange change for her to be the dominant one, but one that isn't unwelcome, especially with the pleasure you are currently receiving from the attention she's giving to your large breasts.

"Mmmm, that was perfect, Finn. You make for such a good girl, we should've done this sooner! Now, for being a good girl, you get a reward!", she said happily as she made you moan again, weakly wondering what her reward could as you just surrendered to the immense pleasure.
