So I have two friends that used to both work with me and they are not a thing. In and out of they they are very "sexual" people and they often talk about their sex lives and kinks. I feel like they would be open to a threesome but I am looking more for mutual masturbation with anal toys such as anal beads, butt plugs, and sleeves. Any advice on how I could convince them to help me "try out my new toys?"
