He had been a good boy and helped me to masturbate to a story I was reading by standing in the corner and looking submissive and femmed up in bra and panties. I didn't want him cumming that night, so I took some measures to prevent that, but told him that next day he would get a good boy spanking.
Next day, when the time came, I took him up to the bedroom. I made him undress to naked, and I did the same. I then sat on the side of the bed and called him over.
With us both naked, me sitting on the bed, him standing beside me, I poured baby oil on my hands and started rubbing his penis and testicles. He was already hard before this, but this got him quivering hard. Whenever he would get too excited, I would stop for a bit, and then restart when he had calmed down. I basically continued this way until his knees were trembling and I could see his eyes begging me for a release.
At this point, I poured some baby oil onto my thighs, rubbed it in a bit, and made him lie face down over my lap in a traditional OTK spanking position.
As he draped himself across me, I felt his hard cock pushing down onto my slippery lap, and sensed how excited he was. I had him reach his left hand back and put it on my ass, and I had him hold my ankle with his right hand. I then took up a little bedside paddle and began spanking him. Not too hard, but hard enough.
The rest of his time across my lap would be a delicate balancing act between, on the one hand, his submission, his fondling of me, his excitement at my nudity, his excitement at being given a spanking by his wife, and the sensation of his cock and balls rubbing against me; and, on the other hand, an increasingly strict paddling.
As I spanked him, he writhed and rubbed across my lap. He knows he is allowed to ejaculate all over my lap if he can manage it. In fact, if he cannot get himself off in that fashion, then he's not getting off at all that night. So I therefore have a very motivated hubby squeezing my ass, caressing my lower leg and ankle, and humping my lap for all he is worth, all the while undergoing a good old fashioned cheek reddening.
As I felt him getting closer and closer, I spanked him harder and harder. At one point his cock slips between my oily thighs, and I clamp in on it hard, giving him a nice tight "hole" to hump. I don't want him cumming like that, though, and by manipulating my legs and timing it, I got his cock back across my thighs, which is where I want him when he cums (I'm thinking of the carpet, here).
A few more hard spanks, little hubby with his ass high and going crazy across my lap (like a dirty little slut), and the inevitable happened. I felt a nice warm series of spurts onto my thighs as he shuddered and yelled out, and then collapsed across my lap, all spent up.
I made him get up and go get a nice warm wash-cloth and towel, as I kept my legs crossed trying to keep the mess off the carpet. He came back and knelt in front of me, and gently, gingerly, washed me off and patted me dry.
That's what I call a "good boy" spanking.
