[M]y mile high experience and acting my way out of a bad situation

This happened years ago shortly after graduating highschool. My girlfriend and I had been together for 1 year at the time. My girlfriend, her brother, and I were going to visit their dad a few states over. This was the first time I was going to meet them, so I was a bit nervous and didn’t want anything to go wrong. My girlfriend was a beautiful 5’5″ brunette with big blue doe eyes. She was thin and had big, beautiful, perky breasts with an ass to match, but my favorite feature of hers were her smooth, soft and perfect legs. The type of legs you want your hand to be rubbing at all times. Her skin was as soft as velvet and I had a hard time keeping my hands off of her. She wore athletic shorts so short I could see a little bit of her ass cheek. Her shirt was an almost see through cream button down with the first few buttons undone to show her cleavage. I am a 6’1″, blonde, athletic guy and a few inches above average where it counts (enough to hear an audible gasp the first time a girl would see me).
