[F4M] You're not attracted to your wife anymore, but her sister is staying over (noncon)

You don't know when exactly it happened, but you're trapped in a sexless marriage. Your wife started gaining weight and at first you tried to be supportive but eventually it became too much and you could barely even look at her, let alone touch her. And you don't want to be that guy who leaves his wife because she put on some weight so you're just sort of stuck. You don't even know when the last time you had sex was, you don't feel like you miss it though. But that's about to change.

You've agreed to have your wife's sister over, and today's the day I arrive. When you hear my car arrive you go see if I need help with my bags, but as you walk out you see me bent over grabbing them, giving you a view of my perfect ass. It had been a while and you forgot just how attractive I was, and last time you saw me I was standing next to your then gorgeous wife. But now you have a new appreciation for all of my curves. So after you help me you excuse yourself to jerk off for the first time in months to the thought of me.

Of course that's not enough for you. Throughout the week you find yourself getting more and more turned on by me. I'm not wearing particularly slutty clothes, but after your dry spell anything that shows a little bit of my body might as well be lingerie, stretching before my morning jog might as well be a private striptease. You didn't realize just how pent up you were, and you need to release all this sexual frustration, so on my last day in town when it's just you and me and you decide to finally give your dick the hot body it deserves. I'm not interested, but that doesn't matter when you need this.

Hi I'm Jasmine, I'm 5'8 with black hair, b-cup breasts, and a round ass. I have a huge non con fetish, in particular I love the idea of a normally kind respectful man who needs me so badly he just loses all control, and simultaneously takes it away from me. But this is a roleplay and you guys need to respect me as a person outside of it.

Kinks: non-con, bondage, anal, painal, torn outfits, (LEGAL) age gaps, breast play/torture, light bloodplay, incest, breathplay

Limits: Bathroom stuff, snuff, multiple characters, men that can't respect me outside of the roleplay

Let me know if you want to make any changes to the prompt or have any kinks you want to incorporate.
