You shouldn't have trouble finding a sub, they are plentiful. I have had relationship with several but it's not mine and my wife's dynamic at all.
Do you want to control their actions and body or mind as well? I'm really into lots of kinky stuff. I love spit play. Love to spit on girls while we fuck or while they are giving me oral. Lick it off them and spit it back in their mouth. I love to rub a girl's pussy wetness on her own Lips making her lick it off or sticking my finger in her mouth. The same could be dome with a guys cum if that's who you are dominating. I also like working a girl up to close to orgasm then stopping short and changing to a very hard bite, just as hard as she can stand, till she cries out and begs me to stop. They it's right back to licking her clit till the pain subsides and working her close again with another dental. As said above, the sky is the limit
Sow you guys have a wild imagination 💭 haha I never peed in anyone’s mouth but I don’t know that’s kinda on the other side of kinky I like try a machine, role play definitely sounds great
