My earliest memories of being turned on by a family member was with my aunt. Soon after I turned 18, she moved across the country and stayed with my family while she looked for a place of her own. My parents both worked, so we were alone at the house the majority of the time. Nothing ever happened between us, but I remember being so obsessed and turned on by the fact that she was my aunt. Suddenly every masturbation session was thinking about her. I would take a pair of her underwear from her laundry, and inhale her scent while I pleasured myself.
I began searching almost exclusively for porn of guys having sex with mature women, so that I could pretend that was me and my aunt. This eventually lead me to find mother/son porn, which led to me looking at my mom very differently. I assumed a lot of guys go through some sort of sexual attraction to their mother, but it quickly became an obsession with me. Every time I masturbated, which was a lot, it was thinking about my mom, or sometimes of a threesome with my mom and aunt.
After years of this, some days I would be so turned on, I would pull out my phone and want to press the buttons to send her a text about my obsession with her, just to see what would happen. But of course, cooler heads would prevail, I would never risk ruining my relationship with her.
Fast forward 10 years later. My sexual feelings towards my mom are still as strong as ever. We decide to plan a hike that would take us 2 days to complete. It was my parents, myself, and my brother who went. We drove 4 hours to a small town beneath the mountain, and got a hotel room as we'd be leaving early the next morning. At this point is was nothing out of the ordinary. We were all sharing one room, and we got settled in and started figuring out what we wanted to do for dinner. My mom was feeling a little tired from the drive, so she decided to take a shower while we figured out dinner.
Another thing you should know about me is that I have a foot fetish. I would take a glance at my mom's feet when I could, but something changed about it that day. When she took off her shoes to get ready for a shower, her toes were painted this bright lime green color. To this day, I can still picture that color. I don't know what it was about her feet that day, but I was absolutely mesmerized and couldn't control my instant hard-on sitting right there in the room. I couldn't wait for my mom to finish her shower so that I could go relieve myself thinking about those feet. And so I did, 3 times just that late afternoon and evening. That night in the hotel was the most turned on I had ever been, and all I wanted was to jump on my mom and passionately fuck her.
