My fiancee and I were walking through a large wooden maze at Greenhills Adventure Park in South Australia, when we came to a series of turns which obviously led nowhere. Of course we had to see what was at the end of it... when we reached the deadend she jumped on me and we started passionately making out. With the wooden slats not doing a very effective job of visually dividing the walls, and with people walking throughout the maze all around us, the excitment became too much to contain. I lifted her up and pressed her against the wall, scraping her legs against the rough surface. She pulled up her skirt and reached inside my pants, getting out my throbbing hard cock. She was wet already and it slid in easily. We started going at it against the maze wall as if we were the only ones in the whole park. It became intense, with the massive adrenaline rush causing us to breathe heavily. Suddenly we heard a group of people foolishly coming down our corridor of the maze. Consequently I pulled my cock out of her and we dressed quicker than ever before, trying to act normal, despite our flushed faces. It turned out that our quicky left a small graze on her knee from thrusting into the wall, which she didn't even notice until later. She still has a scar from it today which always brings a dirty smile to our faces!
