Unexpected toilet fun

Was in a cafe and innocently went to the bathroom to wash my hands, as I was washing them I could see a guy at the urinal in the reflection of the mirror and he was taking way too long to actually be pissing so I knew he was cruising. He then came over to wash his hands and we locked eyes in the mirror. I went over to the urinal and he follows and whips out a long thick cock. I jerked him and sucked him right there. What a rush especially when I wasn't seeking it out.
