“Masturbation without permission, guilty as charged. I hereby sentence you to two months locked in a chastity device of your Master’s choosing.”

I cringed as I heard these words, although I’d never worn one of these devices before.

It’s been a month now and the chastity device he locked me in isn’t as cruel or painful as I thought it would be. Its actually comfortable, and comforting — the ring makes my balls feel so secure and my cock has a nice home in its tube. That is until I attempt an erection; that’s when the device shows its devilish side. Unfortunately, there are enough hot men in this city to give me dozens of erections every day.

Today, it was the guy sitting across from me on the train. I casually noted his muscular chest and arms under his tight fitting dress shirt and tie. No big deal, although he was young and very handsome. It was when my glance found its way inevitably to his crotch that the problem started.

One foot casually placed on a ledge, raising his knee almost to chest height gave me an unobstructed view of his groin. And oh what a view. His dress pants were light grey and thin, a warm weather suit for a hot day.  They weren’t tight at all, in fact a bit baggier than the fashion. Which made the sight of his bulge all the more amazing. It was clear he had no underwear on. It was also clear that he was circumcised, as you could plainly make out the outline of the fat mushroom at the head of his cock. Judging from where his cock ended (somewhere to the right of his fly) he appeared to be sporting an 8-inch dick. Soft.

Looking further down I could make out his balls as they rested on the seat.  The seemed to be about the size of a tangerine. Each time he shifted his body, his package moved provocatively inside his suit. Being commando, he would occasionally “flip” the position of his cock with his hand. He saw me looking at him as he did this and realizing he had been caught touching himself in public he turned red. But he also had a hint of a smile on his face, as if he got off on being found out.

Meanwhile, back in my chastity device things were starting to swell. The device my master had placed me in included a built-in switch which operated on a small rechargeable battery.  Once my erection caused enough pressure on the base of the tube, the device would send a series of small but painful electric shocks to my cock and balls. There would be 10 jolts, possibly more. If I was able to control the erection they would stop. If not, I’d get another 10 shocks delivered and so on, until I got my boner to subside or the battery ran out. It was a twelve hour battery by the way.  And another month to go!

I had just about got my dick soft again by the seventh shock and I thought I was home free. But I had to have one last look. Stupid, I know. Especially since the guy, who I now realized was wearing a wedding ring, decided at that moment to adjust his package. A lot. We were the only two at that end of the car, and he took full advantage, pulling at his pants and grabbing himself, almost stroking that massive dick. In fact he DID start stroking, looking at me straight in the eye as he did so. I tried to look away but couldn’t. The shocks continued all the way into the city as I tried to keep my expression from revealing the pain I was in.

When we arrived I watched as he got up, his semi-erect cock, having no support, pushing against his suit pants to a wet spot at the top of his tent. How was this guy going to go to work like that, I wondered?  as he rose handed me an envelope. I started to say something but he quickly departed the train and jogged up the stairs to the platform above.

I got off the train and made my way to the coffee shop on the mezzanine, all the while stifling the urge to try and rip the device off my cock and balls. This I knew would be fruitless as I had attempted many times in the past month, only to be rewarded with more shocks. I sat down with my coffee and opened the envelope to find a typed note inside:

 

Dear faggot:

I hope you enjoyed the ride. Raymond (the cute married guy who handed this to you) is one of my other subs. His assignment today was to go to work commando under his suit, find you on the train and do whatever he could to make you horny.  If he was successful, you must have had a “shocking” train ride this morning!  Next time don’t disobey me when I forbid you from masturbating or the punishment will be far worse!

Your Master Dan

 

It was going to be a long month …
