I used to work at a very fancy department store. Men had to wear suits, women in dresses, skirts and tights.

I worked in the 'young men's' department (specializing in clothes for 18-40yr olds) and it was incredible for a horny sub like me. I was able to help dress the guys who'd come and ask for assistance - most were clueless about what size they were. They'd give me an idea of what they'd like, and it was up to me to help.

I even would have to measure their pants if they needed their jeans altered. Nothing turned me on more than having to bend down and tuck the ends in - sometimes I'd even prick my fingers with the alteration needles to excite myself even more.

One day, an acquaintance of mine came by to check out some of the sales. I asked him his size and he told me I'd have to check out for myself since he didn't know. He gave me a slight grin, looked over to the dressing room and headed here. He turned around and nodded for me to follow. It was close to closing time, so it wasn't busy nor was I worried about other people coming by.

We went to the biggest dressing room and there he undid his jeans. He was already hard and ready for me to suck him. I got down on my knees and he shoved his cock in my mouth. Having to take every inch. And boy did I suck hard. Gagged a few times and had my hair pulled.

Knowing we couldn't be in there too long, he came quickly and even a little bit dribbled down my cheek and I wiped it off as I calmly walked out of the dressing room, fixing my hair.

He ended up buying a pair of socks and then invited me over to his place the next day.
