Looking for an ongoing FWB for him. 

They've been together almost 19 years, married for almost 12 and in the lifestyle for the last 6. He's a straight sensual Dom and she's HIS brat. She can be a switch once in awhile with women..... This is something that they've only in the last year, put a label on. They've always had this type of relationship, just never knew it was part of the BDSM scene. Since then, they've learned a lot and that particular bond has only gotten more intense/amazing.  She's a Cuckqueen so knowing he's with or seeing him with another woman, turns her on. In turn, that turns him on.
