GyneDoll, your description of anal sex with your husband is the most erotic thing I've read in some time. I LOVE it when you said,
"I'm in charge of him then. I can flex my muscles and milk him like a cow."
I think your husbands penis must be slightly inside your inner sphincter at the top of your rectum. When you clinch and relax your butt, your inner sphincter opens and closes to squeeze the head of your lucky husband's penis. I'm amazed that you can just sit there locked together without squeezing and cum like crazy when he presses and rubs your belly button. I love how you wait until you've cum enough, and then for the grand finale you flex your muscles to milk him like a cow. I'm thinking MOOOOO! Very HOT!
A female bisexual zity member I'm friends with PM-ed me about doing the same thing you do during her anal sex with her lovers. I PM-ed back, half jokingly, that I'd hop the next plane up to her city if she wanted to try that on me. No invitation yet. I'll put you in touch with her if you want to meet her and she agrees.
I also read a really hot Zity post by a gay guy who says he loves to do the butt muscle flexes to squeeze the head of his partner's penis with his inner sphincter. He sits on his partner so he has him pinned and unable to move his hips. With very subtle hip motion and butt muscle clinching, he brings his partner right to the edge of orgasm, which he can feel right before it happens. Then he backs off a little and flexes his butt muscles just enough to hold his partner for 30 minutes or more right on the brink of orgasm. The tension build and builds until it's unbearable for his partner. Finally he very slowly revs up the butt muscle flexes to give his partner an orgasm so violent that it makes him cum too! After I read this very hot post, I posted back that I wasn't gay, but now I want to give it a try!
I wish my wife enjoyed anal sex as much as you do. I'm still trying to train her. Maybe I'll have her sit on my lap the next time we have anal sex and try the belly button trick. If I could just get her to cum anally one time, it might be enough to get us on the road to enjoying anal sex as much as you and your husband do. Now I'm motivated!
Please share any other tips you have to help me make my wife love anal more.
