Take it like a man...er woman?

With a sigh I crawled onto my knees and aimed my ass towards my wife/best friend. I watched in the full length closet mirror next to my bed as Mike eagerly positioned himself behind my naked wife. Either some part of me hidden in the deepest part of my mind, or perhaps my wife's body was very turned on by the sight.

Was it possible my wife was turned on by my best friend?

Before I could consider that thought any further, I began aware of a firm pressure against my asshole. For a second I had time to think I had made a horrible mistake, and then she pressed into me. We both moaned, her in pleasure and me...not so much.

Having been on the other end of anal sex before, I knew what Susan was feeling. If you were well lubed, a nice tight asshole felt far better than a pussy any day. It was nice and warm, but so much tighter than a vagina could ever be.

Plus, there is this strange dominant feeling you get when you're buried balls deep in someone's asshole. In the back of your mind you know you are in complete control and there is nothing they can do.

I can't speak for how Susan felt when I fucked her in the ass because my cock was nowhere near the size of Mike's giant meat, but I felt like my asshole had just been ripped apart. My moans turned to near screams as she slowly but steadily worked her way deeper into me. She didn't seem to notice, or care. My wife was suddenly overcome by her new masculine lust.

"Holy fuck that feels so good," Susan moaned.

I lay face down on the bed and made strange alien sounds into the matress. I thought I was going to die.

And then I felt her hips against my ass. She stopped moving for a moment and just sat there, and the severe pain in my asshole subsided. There was even a slight pleasant feeling.

"I didn't think it was going to fit," she said with a giggle.

"You told me it would!"

"I just...I really wanted it, so I just told you that," she said. "No wonder you like this so much."

"No wonder you don't!"

"It gets better from here," she said. "Now its all stretched out and ready to go."

Then she started fucking me, slow at first but quickly getting faster. It actually was much better now. It still hurt, but the pain was outweighed by a bizzare sense of pleasure. I had my best friend's cock in my ass and I actually liked it.

"I could do this all day," she said as she pounded in and out of my ass.

"Please...no," I begged, but I started orgasming just the same.

After about a half hour of hard anal sex, the lub was beginning to wear off and the pain was coming back. But Susan was in control. There was nothing I could do. At last she took a firm grip on my hips and gave three huge thrusts as she emptied her balls inside me.

Finally she pulled out and fell back onto the bed.

"God, I love having a cock," she said, breathlessly.

Susan checked the clock, slapped me on the ass and grabbed my phone.

"Time to get ready for work," she announced.

She punched a few buttons on the screen, and suddenly we were back to our own bodies. Unfortunately, the ass fucking I had just taken didn't seem to have made the transition. My rear entrance still felt like I'd just been fucked by a hung black stud, and I could feel cum running down my thighs.

"Oh fuck, that sucks," Susan said. "You might want to clean your ass up before you get dressed. I should warn you, you might see a little blood after that."

I lay face down on the bed trying to recover as she showered.
