From the age of 13 my mom and I began to visit my aunt every Saturday. She became best friends with a lady who lived next door to my aunt called Kate. Kate was the same age as my mom who was 39 at the time. Around the age of 15 my mom and my aunt would go shopping each week so I asked if I could stay with Kate (I hated trawling round the malls). One afternoon Kate caught me masturbating in her bathroom, Id forgotten to lock the door. I thought she was going to tell my mom, she didn't she moved my hands away from my erect cock and bent down, taking my hard cock into her mouth. It was my first ever bow job. Every week after that I couldn't wait for my mom and my aunt to go shopping. Up to the age of around 17 I would stay with Kate and each time we'd have sex. From initially just blow jobs to her teaching me for hours on end, how to eat out her pussy and ass. Moving on finally to fucking her pussy and ass, she taught me everything I know. She wasn't the best looking woman, but she did have fantastic body with large ripe breasts and wonderfully large clit. She was also the dirtiest bitch I've ever fucked, there was nothing she didn't want to do or try. Not long before my mom died late last year, she confessed she knew I was fuckng Kate, because Kate had told her. I've been married to my wife for seven years, but in all honesty, she doesn't come close to Kate's horny ways of fucking.
