This is a true story.
When I was a young man, I worked for a gentleman who had his own business. We'll call him Frank. I needed some money, so I took a job working in his store. At first, it was a normal employer/employee relationship. After working for him for a few months, I think he caught onto the fact that I am bisexual. He caught me checking out some of the male customers a few time and when his older son can by the store, I most certainly checked him out.
It started one night when he needed my help stocking the shelves, as our busy time was coming so I was working late one night after store hours. When we were finishing up, he offered to give me a ride home so my parents wouldn't have to come out. Then he mentioned that his younger son, who was around my age, would be home tonight and asked if I wanted to come over and hang out with him. I figured why not? This was the 80's and game system were in their infancy and I knew they had the latest one, so I knew I'd have a chance to play some games.
We arrived at his house and his wife's car wasn't there. As we got out, he told me that he had forgotten that his wife and his son would be out until late tonight but since we were there, that we should go inside. I'd get to play the game system even without his son being there.
Frank set me up and got the game system going while he went off to do something else. After a short period of time, he returned and I was focused on the game, intently shooting some aliens or trying to finish some sort of quest. Frank sat beside and behind me. I was turned a bit towards the TV. At first he started goofing around, trying to make me crash, or my character die or whatever. His quick poking and tickling eventually turned into his hands under my shirt near my waist, again tickling me to try to distract me, all while pretending that his intention was to distract me from the task.
