This part of the story is true. I'll post a second part either in this section or in the fiction section later.
Years ago I visited a small BDSM shop in a major city. I'd seen the owner during my visits to another BDSM store previously, and he was kind enough to help me try on some gags. This time I wanted to try some handcuffs.
The dressing room was a chain link enclosure with sides reaching almost to the ceiling, and covered with some sort of poster board. I told the owner I'd like to see if some ankle cuffs could be used to cuff my elbows a few inches apart, using a small padlock to shorten the length of chain, in addition to wearing another pair of handcuffs. I took off my t-shirt, leaving my jeans on, and waited for him to finish helping another customer.
After a few minutes, he came in and obliged me by cuffing first my wrists, then my elbows, adjusting the length of that chain so that I was forced to keep my shoulders back. I loved the feeling, and how I looked in the mirror.
Just then, another couple of customers came in, and the owner closed the dressing room door and locked it, leaving me in there all alone while he conversed with the customers! I felt both excited and scared, and completely helpless, unable to wriggle my wrists and elbows free, feeling my cock harden uncomfortably under my jeans. And I had to remain perfectly silent and still, barely breathing, so as not to be heard by the customers. When my nose began to itch, I thought I'd lose my mind! I distracted myself by fantasizing about what would happen if my captor decided to take advantage of my helplessness, with or without those two customers.
After what seemed almost an eternity (but probably only about 15 minutes), the customers left, and my captor unlocked the dressing room door and asked how I was doing. I told him the elbow cuffs were sure to leave some marks, which I didn't want (it being summer), and so he took those off. What a relief to be able to be able to move my arms a bit!
My hard-on had returned, and I'm sure he noticed. Here's where I took another risk. I told him I'd wondered what it would be like to have another handcuff secured around the base of my cock and balls, a cock ring of sorts, with the other cuff fastened around the short chain linking my handcuffs. He asked me if I was certain, and I told him I was sure.
He left the changing room briefly, and I heard him say he was locking the door and putting a "closed" sign in the window. He returned with another pair of handcuffs and began unbuckling my belt, unfastening and unzipping my jeans, and pulling them and my underwear down to my ankles. With my shoes still on, I felt hobbled, unable to get away. Not that I would want to. Or so I thought.
The BDSM store owner then loosely fasted one cuff around the base of my cock and balls. A little too loosely, I thought. But I loved the feel of the cold steel, and my cock began to harden some more. Meanwhile, he fastened the other cuff to my handcuff chain. When I tried to move my cuffed hands up or away from my body, the tug at the base of my cock felt so good!
What happened next was unexpected. My captor immediately began to pinch my nipples, very hard, pulling them far forward. Ouch! And not just once or twice. He also ran his strong hands over my chest and abdomen as he stood close behind me. I felt scared, and when he started to stroke my erection I begged him in a soft and nervous voice to please stop. He immediately did stop, and said he thought he was doing something I wanted him to do. I apologetically told him I was really more into the bondage itself, and before a few more minutes had passed I was dressed and heading out the store, with two pairs of handcuffs and a pair of ankle cuffs to show for it.
Stay tuned in this or the fiction section for what I later fantasized happening that day!
And play safe out there!
