I went into the dressing room to try it on. I dropped my pants and out sprung my meat. Looking down at such size was a thing to behold. I fondled it a bit, and it hardened to a semi. I pulled the jock up and my unit hardly fit. It was too big to fit in the XL jock. I poked my head around the corner of the dressing room to see the clerk with one hand rubbing her tit and the other hand buried between her thighs. I knew she got hot as hell seeing my cock when I came in. I bet she wanted more.

"Oh miss" I said. Can you come over here, I need some help. A minute later, she came around the corner of the dressing room and saw me. She stopped dead in her tracks. She stared at my cock.

There it was, a semi hard cock hanging halfway out of the jock. My crimson tip sticking up near my belly button. My huge full sac stuck out the bottom and hung down my leg. I realized it was going to be hard to contain my new monster.
