is it normal that i was aroused by other girls

A few years ago I was at a party and could not keep my eyes off a girl I worked with. In the office she was quite normal, but seeing her with her hair down wearing leather shorts and combat boots seemed like I was in another world. Somehow I managed to get her into the bedroom and it was not long before I suggested that we should take our shorts off. What happened next was the most surreal moment of my life. She said "you like it hot then" and within a few seconds she was spraying something onto my denim shorts. The next thing I realised was that she had applied her lighter to the lynx that she had sprayed them with. For a moment I was scared, but I realised that leather shorts were close enough to prevent the flames from reaching my bare breasts. Immediately we started kissing again and the hotter my shorts got, the more intense it became. After a while the fluid burnt off, leaving the frayed ends of my shorts smouldering and just at the right moment she came down on me, putting them out with her leathers. The climax that followed was out of this world.
