I actually tried anal for my very first time like this with my own mother's older sister when I was a young teenager. I really didn't think it was going to feel much different, but she made me premature ejaculate after only making several thrusts while she was riding me cowgirl like that. I actually came into my own aunt's butt, it felt really weird once I started cumming. I was so embarrassed, she was even laughing.
