Both my gf and I are bi, and she's a dominatrix. She really enjoys watching me get gang raped by several guys, and she frequently invites a few guys to join us, or we go to the skate park and she makes me beg the skaters to suck their cocks. She makes me lick their stinky feet, and tell the guys they are free to piss in my mouth. They often butt rape me, too. After I am done satisfying them, she makes me jerk off in front of them, which is incredibly humiliating. She often films or takes pictures of me when I'm sucking or being fucked. Afterward, we return home and have the greatest BDSM sex. It's worth the effort and humiliation to see her so sexually excited. you might want to try this, too. It's not hard at all to find guys who will allow you to suck them off while your wife watches. Especially if they can bring a friend or two for "moral" support. If you're submissive, getting forcibly raped by a bunch of guys is a very intense experience. Just budget a lot of time because most guys need two or three blowjobs before they are completely satisfied. Start at 9 or 10 on Saturday or Sunday morning, and you'll have plenty of time and energy left over to have sex with your wife afterward. By the way, getting fucked with a strap-on is nothing compared to getting butt banged by a group of horny guys. Skaters are hot and always horny, and open-minded enough to take you up on your offer, at least as blowjobs are concerned. It make take a few weeks to put a good group together, but it's a lot easier if you ask them to bring their friends to the next session.
