My husband and I have experimented with MMF threesomes and a bit of hotwifeing. I guess it doesn't cross into cucking because we never do humiliation or other things I associate with cucking. Anyways one of the things that led us to the direction was my love of the occasional huge cock, and he has a thing for them as well. After we got our first high quality sleeve I found that desire being fulfilled for me and my interest in third parties has gone way down. It seems my husband's desire to play with thirds has gone up as he gotten to play the big cock role more. He says the more he sees me take a big cock the more he wants to see me take them. I am fine with this as I really do enjoy the threesomes, just curious to those who have thought about threesomes in any form, did using sleeves make you engage more, less or about the same as you did before sleeve play?
