My girlfriend and I always liked to play some exhibitionist games. I would like buying revealing dresses, then my girlfriend would wear them and turn heads and we both had a kick out of it.

We’ve done this for a lot of years and still enjoy it but in the beginning we hadn’t quite figured out how to do it well and we had to experiment a lot.

One of our favorite places was the gym. I would sit on a workout bench somewhere out of sight and observe as my girlfriend would “accidentally” flash others in the gym.

I would prepare the clothes, like in this little “sketch” where I had made her top very short. It was a wonderful invention because it would look normal but once she raised her arms, it would expose her breasts.

She would walk by these guys and make sure they noticed her but make sure they didn’t see that she noticed them.

And then … seemingly oblivious to her surrounding, she would stretch and raise her arms, letting her blouse raise up and we would enjoy their reactions.

One other prank we played, she was not wearing underwear and she would sit on the exercycle and let her skirt ride up.

No one could really see anything, but they could see she was not wearing any underwear.

On this day, I guess my girlfriend was getting impatient that no one was really noticing, so she decided to stand up in the bike and really give them something to look at. I nearly choked on my water bottle.

She was peeking every so carefully to check that she caught the attention of the guys and boy did she.

Once she was sure they noticed her, she would pretend like she hadn’t noticed anything. That was part of the fun, you see.

Standing up in a bicycle like that is actually quite hard for prolonged periods so she had to sit down from time to time. They kept an eye on her and each time she got up again, they poked each other and discretely pointed.

Suddenly something happened that we had not expected.

It was like they were spectators in the play that we were performing, but to our surprise, these spectators could actually interact with the performers – because it was not really theater.

One of the guys took her display as an invitation, reasonably so, and started fondling her.

Now what happens next none of us expected, but perhaps we should have.

He pulled down his sweat pants and started pushing his cock up into my girlfriends pussy.

She glanced at me in surprise and I didn’t know what to do, and just raised my eyebrows. She glanced away again, because part of the game was to not reveal that her boyfriend was there in the room as well.

He looked around at his friend while he continued fucking my girlfriend and also looked around the rest of the room. When he looked at me, I pretended I hadn’t noticed anything. Others did the same, although I am not sure if they really didn’t notice or just didn’t want to get involved.

She was really getting into it too and was having trouble keeping quiet. After a minute of fucking her deep, he started slowing down and despite him not making a sound, it was clear enough that he was right now cumming in her. He pumped a few times in the end and then pulled out with cum following out, landing on the saddle.

My girlfriend then reacted in the most epic way.

She sat back down on the saddle and continued working out on the bicycle as if nothing had happened. Brilliant.

After this day, we made some ground rules about what to do if ‘spectators’ would start getting grabby. We didn’t want this sort of thing to happen again, although it did a few times, most notably a day on the beach when she was drunk and sleeping nude, while I was going for a swim. When I looked back I saw her being fucked by a passer-by. Actually not a nice thing to do, although my girlfriend didn’t seem to mind.
