There I was, laying on the couch in my mom's house, with her riding my dick. I was looking up at her beautiful face and sexy body. I shot my load, but was still hard. She kept riding me.
Her rather large tits were bobbing away as she bounced faster and faster, gyrating and wiggling her hips. She was calling my name louder and louder. Then she spun around and gave me the reverse cowgirl.
I loved the sight of that big, juicy ass moving all around. I started to squeeze and play with it. Firm, yet supple. Then my mom told me to spank her. I smacked one cheek and then the other. The way they jiggled when I smacked them was such a turn on! She told me to spank her harder. As my mom continued to ride my dick, I spanked her ass harder and harder. It turned a lovely shade of pink. Those large, pink ass cheeks jiggling like wild. I was spanking her as hard as I could by this point.
Mom's voice went up a few octaves. She tried to say "Oh God" but never quite got the "d" out. She screamed at the top of her lungs, "OOOOOOHHHHHHHHH GGGGGGGGAAAAAAAAAAAAAAAA HHHHHHHHHHHHHHHH!" My final orgasm of the night was the biggest I had had to date, but clearly nothing next to hers.
Then she laid back, resting her entire body on mine and went limp. We told each other that we loved each other, and she quickly dozed off. I simply existed in the moment as I caught my breath. The feel of her body against mine, looking at her hot body, her heaving breasts.
It took some manipulation to be able to get to my feet. I carried her to bed. I drifted off to sleep spooning my mom, our naked bodies pressed against each other.
Over a light breakfast, mom told me, "You were amazing last night!" Before I could thank her, or return the complement, she added, "but I was bad." I opened my mouth to disagree, but she was on a roll. "I was a very bad girl, and I need to be punished."
Was I hearing this right? Did my mom want me to give her the same kind of spanking she used to give me years ago? Sure, giving her ass a good handspanking while she rode me was all manner of hot, but this seemed completely different. As a little boy I dreaded hearing my mom say that I was a very bad boy and needed to be punished. Or, more accurately, I dreaded what inevitably came after. I had to bring her the paddle, then go over her knee for a long hard barebottom paddling that often left bruises for a day or two. Or possibly the belt. The belt was even worse.
I used to fantasize about spanking her the same way. At the time, it wasn't even a sexual thing. In reality she was big and I was little, and she spanked me as hard as she could. No warmup, no mercy. I fantasized about reversing that whole thing. In more recent years, my fantasies were completely different. They were much more like what we had done last night.
I had been with just a couple of girls before, and one of them was into spanking. My frame of reference for what was generally done in a sexual spanking came from her. It was still over the knee on the bare. She had me start with just my hand, giving her light taps. It slowly built to a hard paddling, leaving her ass dark red. This was within the context of roleplaying like I was her dad. I enjoyed it, but it wasn't a big turnon for me.
Did my mom want what that girl wanted? Or something more?
