Fucking my pet up the ass

I had told L midway through last week that I was, once and for all, going to fuck her up the ass this weekend. We had never gone down that road yet in our relationship; as I've said before, we assumed that because of my size it would be way too uncomfortable, and I, of course, being sensitive to her feelings, avoided it.

But ever since we signed the contract and I became her owner, I wanted her ass more than ever. I wanted to make sure she knew that all of her holes belonged to me, to penetrate and fuck as I saw fit. I wanted that feeling of total dominance, and for her to know that no matter how it felt for her, she had no control over the situation.

Friday night came, then Saturday came and went, and L kept dropping little hints that she wasn't too keen on the idea. "We can take a pass on this one. I've been a good girl," she said, and at one point, there was a part of me in the back of my mind that thought maybe I would let this one go. But then I realized that to go back on doing something I said I was going to do would be a HUGE mistake and that I needed to stick to my word.

Sunday afternoon we went up to my place and got into bed together. I didn't bother with any of the restraints or the blindfold, but instead collared and leashed her and played with her for a bit. The collaring and leashing is a huge turn on for me and elevates my primal lust for her to, at times, startling levels. I ran the chain part of the leash around her nipples, rubbing the chain against them, using the strap of the handle to slap at her nipples. I then got on my knees on the bed and used the leash to jerk her head towards my stiff cock, which she eagerly took in her mouth. We adjusted to give her better access and to really go to town on me. I looped part of the chain around the base of my cock and watched as she took in as much of me as she could, using both of her hands to stroke me at the same time. The feeling was so damn good that I almost changed direction right there and was going to come deep inside of her mouth and force her to swallow. I think L was hoping for some of the same as well as she increased her motions when the swelling of my cock and thrusting in her mouth indicated I was close...

But I stopped and pulled out.

"This has to happen, you know," I said. "I have to fuck you up the ass."

She whimpered and turned over, removing her thong and presenting her ass to me obediently. I reached into my dresser and pulled out the bottle of the lube which I squirted on her backside and let trickle down to her ass. Using my finger, I massaged lightly before I inserted my well lubed finger inside of her. She was tight...very tight...and she responded accordingly.

"Wait...please wait..." she said.

I then lubed up my cock, which was throbbing and straining for release. "This has to happen," I said. I rubbed my lubricated cock along her ass, teasing at first, and then slowly started to penetrate her ass.

"Oh God," she said. "Please, you said you would go slowly...please."

I got the tip in at first and then paused, lettering her loosen up and relax as she adjusted to my girth. Slowly I slid in a bit more, and at one point stopped and let her ease her ass back on to my cock, taking it in as she could. I was being rather nice, I realize, in letting her adjust and being patient, trying to avoid my own urge of just taking her and fucking her HARD, slamming in and out of her tight ass with the same power I do when I fuck her pussy.

Finally, most of me was in her, and I pulled back out and slowly entered her all the way again.

"Please don't take long," she said. "Please come soon."

I realized that was not going to be a problem. Though I wanted to slap her across the back of the head, grab her hair and pull her back ferociously while I fucked her in the manner I saw fit, I also wanted to be somewhat sensitive in this first time endeavor and then escalate things from there.

I began thrusting, not going too hard, as I grabbed her ass and looked down to watch my hard cock, shining with the lube, pull out of her tight little ass and back in again. "Is your Master fucking you up the ass?" I asked. She began moaning, and I don't know if it was because of pleasure or discomfort, but I was in my own world of pleasure as I continued thrusting in and out of her. As the pace quickened, she sensed my impending eruption.

"Fill me up baby," she said, and no sooner had she said that then I came with ferocity, as my orgasm rippled through me and I shot load after load of cum deep inside of her ass before I collapsed, panting, on top of her.

Pulling out, I lay next to her panting, handing her some wipes to clean herself off as she curled into the fetal position, my cum trickling out of her ass.

I had fucked my pet up the ass and goddam, was it good.

I held her and kissed her and thanked her before we left back to her place, told her she was a good pet and would be rewarded, which I did by having her take a relaxing evening. Later that night as we lie in bed together I asked her if her ass was sore, which she said it wasn't. In fact, it was the one body part that wasn't necessarily sore as she complained (somewhat) that her nipples (which I spent some time on this weekend) were quite sore and her pussy felt tore up from the rest of the weekend.

But her ass? Felt fine for the most part.

Next time she might not be so lucky.
