Semi-public orgasm

Recently, the wife strapped a remote control vibrator to my cock when it was not in its cage. We went to the store. While she is ordering me around to get stuff for her, she turns it on. She sent me to get somehting far from her. I was reluctant to leave her and the remote control. She ordered me to go. Knowing the vibrator could not be turned off and I was surrounded by strangers was very exciting for me. I ended up having an orgasm in my pants before i could get back to her where she could shut if off.
