Threesome!

How the hell do I ask someone to join me and my boyfriend for a threesome? Like I can’t just ask a friend that lol I’m sure they would think I was super weird and probably not talk to me anymore or how would I get a friend of mine to think of me in that way even if it was just me and her? I don’t think she would want too I’m not sure! 😅 but I wish I could be with a girl so bad just to experience it we don’t even have to have sex just suck on my boobs and I’ll do the same 🤣
