I met Steve at a bicycle race. We had finished next to each other, sharing third place in a big, local race. After that, we hooked up often on training rides and raced against each many times while remaining friends. We lived in adjacent towns about 50 miles apart. I knew Steve had a girlfriend but I only saw her once at a race and only from a distance. She was tall, with long, blonde hair and what looked like a great body.
Sometimes, on training rides, Steve would talk about Debra and how uptight she was sexually. He mentioned that he was trying to get her to loosen up and enjoy herself more, and act out the few fantasies they had shared. He surprised me one afternoon by asking me if I would do him a big favor. He explained that he had convinced Debra to go to an adult movie theater outside of their town, and he wanted me to help her push past her limits. He said that she agreed to show off with him in public, but was afraid of what might happen. He had her convinced that it would be safe if he was there, but wanted me to act like an innocent bystander for her. That way he would know that nothing bad would happen to her. I was expected to watch and participate only if it seemed like she was willing to continue. I agreed immediately, and Steve told me where to watch from and when to approach them. After that, it was all up to Debra to decide what to do.
I got to the theater early and choose a seat in the back row of the balcony. I waited for a few minutes before I saw Steve and Debra making their way up the aisle. She was wearing heels, a very short skirt and a sweater top that was halfway unbuttoned. They sat two rows in front of me and several seats to the side. No one else was close to them, and the lights were pretty low in the balcony. The movie started and I kept an eye on Steve for my signal. They hugged and kissed in between the sex scenes on the screen, and I could see that Steve had his arm around her and was playing with her breasts. Soon, her hand was in Steve's lap and I could see pumping motions of her arm.
Steve gave me the arraigned signal, so I quietly made my way into their row and sat next to Debra. Steve and Debra were locked in a passionate kiss so she didn't notice me right away. I could see that her left fist was wrapped around Steve's dick, and he had opened her sweater enough so that one breast was completely exposed. He was squeezing it and pulling on her nipple. Her short skirt had slid up showing a lot of her bare thighs above her stocking tops.
