The anal sex really turned me on.

"I really liked...when you...were having sex...back there..." I stammered. I was embarrassed to be having this conversation, but I was incredibly turned on by the thought of Samantha getting ass fucked hard.

"Back there? You're so cute when you're nervous. What did you like? Say it." She said with a sensual grin.

"I liked watching you get butt fucked."

"Did you wish that was you fucking me in the ass?"

"Yes." I said, swallowing hard. Samantha opened a drawer and pulled out a small bottle of lube.

"I'll teach you the best way to drive a girl wild with anal sex. First though, I need to make sure you are hard, and your dick is wet." She unzipped my pants and pulled my cock out. There was a bead of pre-cum on the head of my cock. She licked it off before engulfing my entire shaft in her warm mouth. I put my hand on the back of her head as she slid lips down the whole length of my shaft. She sucked me softly and slowly, finally pulling back. Samantha bent over the chair and hiked up her skirt, and slid her panties down to her knees. "Now really lube up my asshole, and make sure your cock is lubed too. The secret to great anal sex is lots of lube."

I squirted a healthy amount of lube into my hand and massaged my erection, then I squirted more onto her little asshole. I pushed my cock into her tiny hole and felt the resistance to the penetration.

"Hold on baby, just stay like that, and let me back onto you. Don't **** it. Lesson number two, give the woman some of the power. She'll relax more if she's not afraid that you're going to just slam it in." I took my hands off of her hips, and just stood there, aiming my erection to her tight butt. She started backing up on me. She took a deep breath, let it out slowly and suddenly the head of my cock entered her ass. "Ok. Be gentle, and go slow."

I began to slowly pump, going a little deeper each time. I stopped once to pour more lube onto my shaft, but then continued the shallow penetration. After a few minutes I could feel my cock going deeper into her ass. I grabbed Samantha's hips and began to be a little more forceful in my pumping.

"Oh my god James! Oh, your cock feels so good in my tiny ass! Keep going! Fuck me!" I was worried when she raised her voice. Would her kids hear me sodomizing their mother in the computer room? Reflexively I reached around and put my hand over her mouth as I plowed her. Samantha's muffled screams turned me on even more, and soon I could feel myself orgasming, shooting a load of jism in her tight MILF ass.

"Oh my god James! That was incredible! You are going to make some lucky girl very happy" Samantha said.
