From an early age I had a good relationship with my moms sisters husband Aaron, my uncle by marriage. Around the age of 15 I began to imagine myself sexually with him and often masturbated thinking of his muscled body and percieved large cock. A year later my aunt and Aaron split up and by my 18th birthday they'd gotten divorced.
Out with friends at a bowling alley I met Aaron and he couldn't take his eyes off me. I knew I'd grown from the kid he knew, to what my friends call me, a very attractive slim young woman. We chatted about old times and I soon forgot about the game I'd been playing. Aaron asked me if I wanted to go to a bar and without thinking I said yes. Two hours later we were exiting the bar and heading off to his apartment, because I'd told him about my fantasies and also about masturbating to the image of his muscled body.
My mom got in touch by text around 1 am asking where I was. At the time of the text I was on my back with my legs around my Aarons shoulders. His enormous cock was just sliding its wonderful way up my tight asshole, which I love being fucked. We'd been having sex for over two hours and he still wasn't finished pleasuring me. I'd cum more times with Aaron, than I had with all my boyfriends put together and with his cock inside my ass, I was about to cum a whole lot more.
I text my mom back twenty minutes later saying I was ok and on my way home. I arrived home after a lift home from Aaron, with a glowing feeling of total sexual high and a butt full of Aarons cum.
No one knows were having a secret affair and I can't let my aunt know for sure. So myself and Aaron will just have to keep meeting in secret, so I have his awsome cock when I want it.
