Morning all - am looking for someone with a creative imagination to write me a bit of a sex story please - essentially has to be written in the first person, you’d be my wife’s sister, and you’re seducing me at my home in front of my wife, but she’s unaware. I’m looking for a particular scenario that’s always been in my head, my sister in law is wearing black nylons, puts her feet on my lap, rubs my legs gently with her toes and then my inevitable erection! Then moves on from there. Let me know if u can do this today please =)
