I don't know how it happened. But here I was on my back, my beautiful wife was between my legs, my feet in the air and she was humping away furiously, pretending to give me a first-class fucking. If not for the pillow being in the way, my head would have been hitting the headboard hard enough to cause a concussion.
Lydia had a look on her face that I had never seen before. It was scary, yet intensely erotic. She was obviously wildly turned on by the position she was in and she was almost screaming how she was going to give me the fucking I deserved.
I could feel her pubic hair brush against my ass with every thrust and found myself wishing Lydia had a cock so she could shoot her load deep inside me.
Lydia is a very sexual person and happens to be the best woman I've ever been to bed with. Even though she won't let anyone come in her mouth, the blow jobs she gives are extraordinary. She makes love to a cock with her mouth and is capable of making it last a very long time and nothing makes her pussy wet quicker than sucking on a cock. Her pussy is very tasty, mainly due to the amount of juice that flows from it, and I love going down on her.
Lydia has had many lovers since we married, all with my blessing. We have even had threesomes with me and another man taking turns with her lovely pussy, and on one special occasion, Greg and I DP'ed Lydia with him in her pussy and me in her ass.
I am bisexual and Lydia has always enjoyed watching me with another man as much as I enjoyed watching her with her lovers. Yet through all our exploration and fantasizing she never gave me an inkling that she wanted to be the man in our relationship. Dominant, yes. Masculine, no.
She just rolled over on top of me while my legs were open, and as we kissed deeply she just started slowly thrusting her hips. It was an incredibly intense moment and both of us started breathing and moaning harder into each others mouths.
Lydia pulled her lips from mine and pushed herself up so she could look into my eyes. And that's when I saw "The Look" for the first time. She had a look of pure ecstasy that I had seen whenever she was getting a particularly good fucking, but this time there was an intensity to it that had never been present in the past.
That look told me my marriage had just changed forever and my acceptance of it told her that she had just gotten what she wanted: a husband with whom she could express her masculine side and dominate completely. Lydia had won, and had done so in such a fashion that I didn't even see it coming. I had expressed my desire to spend a weekend serving her and another man completely, watching them fuck each other, clean them up properly with my tongue, and whatever else they wished of me, but this caught me off guard.
Lydia took full advantage of the position she had me in. She asked me if I was going to be her bitch forever and all I could do was nod my head. My voice was caught in my throat and no words would come out. But that wasn't good enough and she took a nipple between her thumb and forefinger and gave it a pinch and twist that caused me to let out a load moan from the pain shooting through me.
"I want to hear you say it! Are you my bitch now?"
"Yes, I'm your bitch," I managed to stammer through the pain.
