Once upon a time I got the use of the family car to go to Toronto and check out a bike I had heard about. At the time i was riding a Sears 10 speed that had cost the lordly amount of $65 dollars but had heard of a bike in Toronto selling for $1000 dollars. I made the trip up there, approximately 70 miles just to see it. That however was not the only thing I saw that day.
While looking for the bike shop I passed a movie theatre called the Metro. It advertised adult films and since there was nothing like that in my home town and I was a perpetually horny young guy after I had checked out the bike I went to check out the theatre.
It turned out to be an old theatre that had been carved up into 3 rooms and at the ticket booth you could choose to pay for 1 theatre or for an increased price get admission to all 3 of them. As it turned out I went first to the largest of the 3 and carefully made my way in in the near darkness after coming in from the outside and sat down near the front till my eyes got accustomed to the gloom.
The movie like so many of them from the late 60's was a compilation of pneumatic women moaning as they fucked and sucked various large cocks for us to enjoy. The lack of artistic merit was not a real problem and as I watched I started feeling my cock getting hard in my pants. After about 10 minutes in the place during which a couple of other men had entered or left I could see well enough to decide to climb up to the back of the theatre so if I decided to have a bit of fun I wouldn't be interrupted by the traffic.
I settled in right by the projection booth up at the very back of the room and started again watching the show. I started getting hard again and looked around me to see if there was anyone who could see me. That is when I noticed that in the same row I was in but right over against the wall there was 2 guys sitting side by side. I continued watching the film worried about what would happen if they spotted me jerking off. As I scanned the seats around the room wondering if there might be a better position for me I looked back towards them and could only see one of them. As I looked a bit longer I realized that one of them had bent down and was actually sucking the other one.
Gay sex in Canada had been decriminalized just a month earlier and although it was no longer illegal there were still restrictions about sex in public places etc. I had by that time in my life been involved a few times with men blowing me in secluded spots around my home town. I had in fact returned the favour a couple of times as well so I wasn't shocked or outraged to see two guys enjoying each other in the back of a porno theatre.
