POV: i (your wife's younger step-sister) walk into the room with a towel on where i meet you and your wife already in the room. your wife, my step-sister, has convinced me to be her husband's birthday present and how you can't believe i actually agreed to do it, as it's so taboo but at the same time so dirty and turns me on. While standing there, you are able to see my whole body. i drop the towel to expose myself fully naked. I ask is this what you, my own step-brother in law, wanted to see? your wife's younger step-sister naked? i ask if it's everything you thought it would be. i show off my entire body to the camera, front view, side view and back view, really letting my step-brother in law see all of me. i walk around in front of you. Talking the whole time about how i can't believe i am naked in front of my step-sister while her husband checks me out. Now i really show off my body, doing a body tour, first my boobs, i talk about them and how they compare to my step-sisters. How nice and soft they are, i bounce them a little. Next up is my pussy, rubbing it, spreading it open, really showing it to the both of you. i talk alot about if the you enjoy seeing your wife's step-sister like this. Fully naked and intimate. Next i move to my ass. Grabbing it, spreading it, really showing off my fine ass and asshole. Shaking those cheeks a little. Next, i do a few ass clenches. i Really make sure to squeeze those ass cheeks tight with my muscles. i Do it a few times. After that i finally take out your cock (dildo) for a quick BJ in front of my step-sister that ends in a nice thick large facial. the bj doesn't take long: first i touch the dick in front of my step-sister, then i get into it. then cuts to me covered in cum. the cum is thick and white as it drips down to my breasts. i Act surprised but excited. i Ask if you always cums this quick and this much and that's when my step-sister says says it must be the idea of seeing his wife and her step-sister naked together. Then, with the cum all over my face, i put on a little show for my step-sister and you, i finger fuck my pussy and taste my juices, talking a lot about being in front of you two, about my step-sister, how i bet we both taste the same, asking you how hot is it to see a younger version of your wife, etc. Then i move to my ass and show it off in a few positions and ask my step-sister if she is an anal slut, i finger fuck my ass in a few positions doing some ass to mouth (to the camera) with you and talk about how good my ass juices taste and wish i could taste my step-sisters ass juices. lastly i bring you (the dildo) back in to fuck me, asking my step-sister how turned on is she seeing her husband fuck her younger step-sister, fucking my pussy and then having you cum all over my belly and pussy before pretending to sit on my step-sisters face and have her eat the cum out of my pussy. Dirty talking the whole time.
