The promised anal?

Tom had been a good boy, he had done as I had asked him, so it was only right that I reward him. I stood up from the floor and moved backwards to the door. Tom gave me a quizzical look. I held my finger to my lips to shush him. I backed into the door intentionally firmly closing it. I knew it was possible that John was still behind the door, but the next part of the night was not for his eyes. The latch clicked firmly, but that wasn't enough for me, I took the chair from the desk and placed it under the handle. John would not be able to get in the room without me first having the time to 'clean up'. All done, I turned back to Tom. My dick stuck out in front of me, none of this had done anything to turn me off.

Tom looked spent, he had blown a pretty sizeable load down my throat just moments before. He gave me a half smile and I knew that he didn't have it in him to give me the fucking I yearned for. "Are you sure you can't get hard?" I asked hoping to convince him.

"Sorry Sarah, that blowjob was amazing! And I think I got turned on even more knowing that John was spying on us. I don't think I'm gonna get hard enough to fuck you, as gorgeous as you are."

I gave him an impish look, "That is a shame, for you. Because I really need to get off, there is no hiding this big beauty if I don't cum." I reached down and wrapped my hands around my cock for emphasis. "But, maybe since you are tired, I could top you? All you need to do is lay down on the bed, relax and let my fuck your ass." I attempted to convince him, leaving the last words as a hushed suggestion.

Tom gave me a look that said, I am so damned tired. But much to my surprise his words contradicted the impression. "For you Sarah, anything. But I can't promise any enthusiasm."

I squealed like the young girl I am. "I have enough energy and enthusiasm for the two of us." Then I reached down to my weighty balls and squeezed them emphatically. "And enough cum to go round."

Tom lay on the bed, he placed a pillow under his crotch to give me better access to his beautiful behind. He had such a smooth butt, I ran my hands up and down it. I wanted so much to worship it, but I was also so damn hungry to get started. I knelt down giving myself eye level with his ass. I thanked myself mentally that I had asked Tom to get all cleaned up before he headed over today. Then I dove in, I stuck my tongue straight into his asshole. He tasted strongly of sweat and musk, two flavours that only heightened my arousal. I pushed my tongue as deep as it would go. I wanted to fuck his ass with my mouth, but quickly realised my mouth was pretty tired after the blowbang. Tom squirmed under my attention, his movements were so cute, but also somewhat distracting.

I removed my face from his ass and gave his delicious buttcheeks a hard smack. The sound reverberated within the room and he gave a sharp yelp, but he did not complain further. I tested it out and smacked his ass hard a couple more times, he responded and his yelps became less pronounced, but he was compliant. I smiled, realising another side of my was coming out from this. An idea popped into my head. I reached down below and took his balls in my hand and rolled them back and forth between my fingers, Tom's squirming continued.
