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.
I unbuttoned my jeans, and eased my cock out into the dim light from the screen. I started stroking, and I was fully erect by the time Debra finally realized that someone was next to her. She glanced at me and quickly turned back to Steve before she had seen that my cock was exposed. She whispered for him to stop because there was some guy sitting next to her and tried to cover her breast. Steve said loudly, " I'm almost there baby, just finish me off and everything will be OK." Seconds later, he started shooting off and Debra must have been really pumping because his cum arched over onto the next row of seats. Debra kept stroking him until he was finished. Then he told her to wait for him while he went to the men's room to clean up. Debra pulled her sweater closed over her breasts. She wanted to go with him, but he insisted that she wait in her seat.
Steve zipped up and walked unsteadily towards the stairs at the other end of the row. Once he was gone, I started to move my hand faster, making more noise. Debra glanced my way and I could see her eyes widen and her jaw drop when she realized what I was doing. My cock is only six and a half inches long, but is much thicker than Steve's. She looked back towards the screen, but kept sneaking glances towards my lap. I don't think she had even once looked at my face. Debra was sitting with her hands in her lap. After a few minutes, I stopped stroking and placed my hand on top of her right hand in her lap. She didn't object or pull away, so I squeezed her hand but still got no response. I lifted her hand across the seat divider and put it on my thigh. She immediately pulled away and put it back in her lap. I reached over and squeezed her thigh, then slid my hand up, moving her skirt in the process until I could see her panties. She tried to push my hand away, so I grabbed her hand again and pulled it back to my leg. She didn't move it away so I took her hand and wrapped her fingers around my cock and started stroking slowly, keeping her fingers tight around my shaft.
