My craziest and only situ was over 2 years ago when I met a girl getting into the elevator to the station. I deliberately waited in front of the elevator to prevent the doors closing as I had noticed her walking across the street some 10 minutes before. Apparently she barely made it in after me and the old guy in the elevator was pissed off at her mumbling to her that she's young enough to go up the stairs. This escalated quite lot between the two over the next 15 seconds to the second floor enough to the point it made everyone in the elevator uncomfortable.
As her and I exited down the stairs, I looked at her and we both said something to each other and struck up conversation. Exchanged contacts and 4 days later, I invited her to meet my buddy and I at the Yoyogi. She wanted to bring her sister, and little did we know it was her twin, and they were all giddy because the just had their photo shoot for [Redacted]. My Friend had his finger up the sister's bum while the other and I had our tongues down each other's throats in front of families and teens. Some 5 months later I would find out on my own that they were working at [Redacted] as a duo and the sis was into domination while the one I was with was experimenting with that and trying to find her way. I pretended I never knew she was a pro until she suddenly told me one day.
We had taken trip to the Carribean after she and I got passed that but things went sour because of being married and other various issues of why I was married to 'her." Fighting got pretty bad, but we made amends and occasionally keep in touch. The stuff they were doing overseas was a real niche market that I never imagined was so popular. After seeing and hearing first-hand some of that stuff, I got a different impression of some middle-aged European men's extreme fetishes.
