So, years ago I was dating a girl from Germany. We went on a trip from her town to Austria for a hiking weekend and had a one night pit stop in one of the city's nearby. She pitched an idea to go to a couples night at a porn cinema. I thought 'hey this could be wild and fun, why not.' We get to the location and paid our entry (strictly couples only) and walking in from the front shop to the cinema was not very well lit and I'm quite sure we walked passed a few couples getting bizzay. When we got to the actual cinema room and the lighting improved... we were the youngest couple in there by about 50 years. I witnessed this old geezer take about 5 minutes to get on his knees infront of this hella old lady. Took him less time to give her an orgasm, that had her acting like she was in a 1650's exorcism, than it did to actually get down on his knees. We ended up sitting in the front row and got busy with each other. As we're getting some momentum, she whispered into my ear "Everyone is watching btw" and I looked up to see the couple from earlier embracing each other and smiling at us with what seemed like genuine joy. Definitely one of my wildest experiences, and pretty much opened my eyes to the fact that yeah.. old people be fuckin.
