Maybe 8 or 10 years ago I was able to coax wifey into trying some light spanking and doctor play. When she was the "patient" she reported to doctor as ordered with baby-smooth pubes, tight white panties and bra. I ran my hands all over her as she stood in front of me seated on the bed. Of course it was determined that she had earned some discipline, so I began to warm up her white pantied bottom with a handspanking as she lay on the bed; then gradually introduced a belt, ruler, and mini-martinet (penis whip).
I unhooked her bra, then she was ordered to turn over on her back. Using a small soft nylon flogger, I teased and whipped her titties and stomach. I began rubbing her covered pussy, then went down to investigate with my nose and mouth. A few minutes of teasing, then I pulled her panties off and went back to work on her genitalia with the nylon flogger, which gave way to the stronger licks of the penis whip. When her naughty bits began getting pink, it was back to some bare bottom spanking with the hand, belt, and full-size flogger. Then it was time for some oral clit stimulation, and good hot fucking.
On a separate occasion, we switched roles. She ordered me to report in fresh undersized black bikini underpants, and a white bathrobe. Boy-smooth of course. I stood in front of her as she talked about my misbehaviors, and I needed to be disciplined; but first the doctor had to make sure I was clean and ready for punishment.
She opened the bathrobe and began examining my chest, stomach, legs and feet. Then I removed the robe, and faced away as she looked over my back. Then I was ordered to bend forward, and she spent some time feeling my butt, and between my legs. Then I had to face her as she slowly slid the underpants off, and ordered me to lay face down on the bed.
She spanked my butt with her hand for a bit, then switched over to the belt and flogger. It doesn't take much for me to get pink, so I turned over on my back; she proceeded to repay me for her pussy whipping with some nylon flogger and penis whip on my boy-bits, interspersed with manual examinations (fondling). Then it was flip back over for a teasing temperature taking, and then the anal probe (small butt plug that I wanted to use on her, but no-way Jose!) She did a great job with it, but probably because it was my first time with it I wasn't comfortable nor excited by it.
I tried on several occasions after that to do another scene, but she simply said it really was not her thing. So I really admire her giving it a very honest try, and respect her that much more for speaking her true mind.
And then, of course, just when you think you know where the lines are drawn, you get a curve ball you've never seen at bat before......
Years later on a Thanksgiving trip to the beach, one morning wifey and I awoke early, and decided to fool around a bit. I had on a pair of striped bikini briefs which she began to stroke. Then, just out of the blue she begins a sort of a medical exam scene on me! Wow, we haven't done anything like this for years....ever since she told me it turns her off.
So she is doing her "exam" on me, talking nurse/doctor stuff. I'm just instant hard. She pulls down my underpants and really feels me up. While she often teases me about keeping my naughty bits smooth, she seems to enjoy massaging and playing with me all the more. (Day or so later she let me know she did some trimming "down there" as well) She knows a shaved pussy really turns me on, but won't keep it that way all the time :-(
Then she goes and gets the "male" tube of lube (this is some stuff which is "warm" for males, "cool" for females and when they meet it gets really tingly and hot) and applies a liberal amount to my cock, balls and anus...and starts to aggressively rub it in. Now I'm hard as a rock. Then she puts her lube on her titties and pussy. We usually do missionary, but when she gets hot she wants to be on top....nothing wrong with that! So she mounts and we have a very difficult time not waking the rest of the cottage.
