As we walked over the the changing rooms, she leaned over and whispered into my ear, "If you make any sort of fuss, I'll throw the key away and your cock will never come out of there. Understand?" Puzzled by what she meant, I simply agreed.
"Excuse me sir?" she asked the man standing in front of the changing room doors. "My friend here wants to try on some of these clothes before deciding to buy. Are there any rooms open?"
The man looked at the clothes in the cart, smiled at me, nodded, and then led us to the only open changing room. I didn't know what to do... if I made a fuss, my cock would be locked up forever; but I didn't want to be wearing women's clothes, either.
She followed me into the changing room and assisted me into the dress. She made me model it for her so she could size me up. I looked at her and saw a sinister smile gracing her lips.
"You look good sweetie," she said as she reached down into her purse. I was hoping she didn't have a camera in there--that would be so embarrassing; but, when she pulled out what she was really going for, I had wished it was a camera instead. A large, veined strapon was in her hand and she grabbed my helpless cock with the other. "Do you want this to come off?" she asked. I really did, so I was willing to do anything she said at this point. "Well, there's someone in the room next to us... so try not to scream," she whispered in my ear as I felt the tip of the massive dildo touch my *******.
