During the week I'd made a secret trip to the discreet shop selling the highly specialised merchandise and found exactly what I wanted. Not only that, but I'd also made an undisclosed expedition to the intimate apparel and hosiery sections of a department store in a distant suburb. All I now needed was the opportunity to use my purchases, and that wasn't as long in coming (pun not intended) as I thought it might be.

"The community college is starting a course on art of the rainforest" said Cate one evening over dinner, "and I've enrolled. Do you mind?" she added in the closest I've ever seen her come to a plea.

"No, of course not" I replied in an interested tone. "I know you're how interested you are in that form of art, so why should I stand in your way? How long does it go for?"

"Eight weeks, with one three hour class from six to nine every Wednesday night. Oh, and the first class is tomorrow night" she added in an apologetic tone.

"Not a problem" I said expansively. "Peter and I know how to look after ourselves. We're big boys now" I continued, giving my stepson a confidential wink. He blushed.

*****

It might have only been another 24 hours, but those hours seemed to go by on leaden feet. When Cate finally did leave I gave her another 15 minutes, got the things I'd need from the hidey hole in the hall cupboard and told Peter to go up to his own room.

"My room, Dad?" he asked in a slightly puzzled tone.

"Yes. During the week I bought a few things so that we won't have to use your mother's. It might be hard to explain how something got damaged or, um, dirty."

I'd developed a liking for following him up the stairs: it was stimulating to watch his slim ass move as he climbed them. "OK, strip" I ordered when we were in his bedroom.

When he was naked I got him to put on the matching ivory-toned bra, garter belt and panty set I'd bought, then the tan nylons. The last took a while to get right as they were seamed, but that time was well spent. He looked very sexy with the dark and slightly shiny material on his legs, with the seam straight and running from heel to top. When he craned his head to look at the effect in the mirror I saw his small cock become erect. Of course by this time mine had been that way for a while.

"Do you like how it looks Peter?"

"Yes Dad. It makes me feel...."

"Sexy?"

"Yes Dad. Sexy. And good. It's.... um.... hard to explain."

"I understand" I replied, smiling at him. "I'll just go and get your mother's white high-heeled sandals to complete the picture."

When I brought the shoes back he put them on and paraded up and down for me. I'm beginning to think that this is the part he likes most. I like it a lot too.

Opening the other bag I got out the ropes and the item I'd bought, picked up the short rope and got Peter to stand with his wrists crossed behind his back. Going up behind him I went to tie them together and my nose twitched....

"You've been smoking!!!" I exploded. He literally jumped at my voice. "Don't deny it! I can smell it on your breath!" I'd quit myself a several years ago, so my sense of smell was now much more acute.

"Well! What have you got to say for yourself?" I demanded.

"Nothing Dad. Sorry Dad. Won't do it again" he mumbled.

"I'll say you won't! And to make sure you're going to be punished. Right now!"

With that I stormed out of Peter's bedroom and stormed back in a few moments later with his mother's hairbrush.

"Dad, no.... please, not with that" he pleaded, his eyes widening.

"Yes, with this! Hands on the bed, head down" I snarled. He reluctantly complied and I pulled the panties down off his hips.

Whack! went the flat of the hairbrush on his bottom.

"OOOWW" he shrieked, his body jerking. I'd swung it pretty hard.

Whack! Whack! Whack! Whack! Whack! Whack! Whack! went the hairbrush again, to a chorus of cries from my stepson.

"You've been told any number of times about not smoking, but you went ahead and did it!" I shouted. "You're a naughty boy Peter!"

Whack! Whack! Whack! Whack! Whack! Whack! Whack! Whack! to another chorus of shrieks and cries. He was beginning to sob with the pain.

"I'm doing this for your own good son. Smoking is bad for you."

Whack! Whack! Whack! Whack! Whack! Whack! Whack! Whack! By this time the skin of his ass cheeks were red more or less all over. I made a mental note to myself to practice spanking on something so that I did it more accurately. An unevenly red bottom is not aesthetically pleasing.

"Alright, that should teach you a lesson" I said as I went to return the hairbrush to Cate's dressing table. "Now, where were we?"

"Ah yes", I went on after a pause. "It's bondage time. Stand there with your wrists crossed behind your back" I directed.

Picking up the first length of rope I used to to tie his wrists together, quite tightly this time.

"It-it's a bit tight Dad" he winced.

"Part of your punishment son" I replied in an offhanded tone. The next length of rope bound his arms to his body below the sock-stuffed bra. It too was tied fairly tightly.

Getting Peter to sit on the edge of the bed, which he did very gingerly, I also tightly tied his ankles and legs, both above and below the knees, being careful to avoid snagging the new new nylons. Standing back I admired my handywork, which looked much better this time. The loops of rope looked really good on his limbs and body.

"One final touch" I said, picking up the red ball gag , which I'd bought during the week.

"D-Dad, d-do you have to... " he trailed off, looking a bit nervous.

"Oh, goodness me yes" I replied. "It really wouldn't be proper bondage without a good gag, and a ball gag is about the best. Open up now, like the dentist says."

After a pause he reluctantly opened his mouth and I pushed the ball into it. Taking the staps I buckled them up at the back of his head, firmly but not tightly. Then I stood back again to admire the whole effect. And to enjoy the feeling of a really rigid hard-on. Glancing down I could see that his own small cock was making a definite ridge in the front of the panties.

"Can you breath OK?" I asked. He nodded.

"Alright, I'm going to leave you like that for the next half hour to reflect on why you have been punished." I heard a series of mummphs around the gag as I left the room. Anyway, I really needed to jerk off.

*****

Right on cue I went back into Peter's bedroom and removed the ball gag. He gasped a few times and worked his cramped mouth. I left him tied up.

"Dad, please don't tell Mum that I was smoking" he pleaded.

That, I thought, was a reasonable request. Her own father was a heavy smoker and had died from lung cancer, so she was in the habit of taking every opportunity to condemn the habit. If Cate thought that her own son had been smoking she'd probably give him an endless series of long lectures. Long moralistic lectures can be harder to take than a good spanking. The thought crossed my mind that I could leverage on this, and my cock stirred again....

"I should you know" I pronounced magisterially. "After all, she is your mother and has your best interests at heart."

"Yes, but she'll.... well, carry on.... " he trailed off, obviously unwilling to add slander and insubordination to crime.

"Hmm" I mused thoughtfully, playing the part of man balancing one consideration against another. "You have been punished, and I'm sure that you've learned a lesson. Haven't you?" I went on, placing one hand on his head and letting it slide to the back of his neck.

"Yes Dad."

"I don't want to catch you smoking again Peter."

"No Dad, I promise."

"Good boy" I smiled. "In that case I don't think your mother really needs to know about this, err, lapse in behaviour." He looked relieved.

"In return, my little lady boy, you'll do whatever I want you to. Won't you?" I added, sliding my hand down his front and cupping it over the sock-stuffed bra cup.

"Yes Dad" he replied faintly.

I untied my stepson and told him to get out of the lingerie and into his own clothes, while I put my wife's white high-heeled sandals back where they belonged. Before going back downstairs I cautioned Peter not to let his mother see the rope marks on his wrists, arms, legs and ankles.
