I certainly have. Sometimes every night for a week or so.
After training and sharing my wife as a sexual submissive I then told her and encouraging her to tell me about and pursue guys she wanted to fuck. We thent thru a length of time where i told her I would only fuck her if she had a used pussy. It was pretty fantastic...
I play in a band and just love being up on stage and seeing my wife heading off to the parking lot or men's room with a hot black guy she's met. Along with bending over for the guys she gets so turned on to give a hot blow job or suck them off, then to make sure I see her walking back as she seductively licks her lips.
I do tell my wife to make sure the guys know she is available
