This occurred a long time ago when I had just turned 18. I had graduated high school and was working in construction, which was horrible. My aunt Jesse was staying with us temporarily. We had a 3-bedroom home and my room, and her room were next to each other upstairs. We shared a bathroom between the two bedrooms.
One night, late, about midnight, I was in my bedroom, horny, as all 18-year-olds are. I heard a vibration noise coming from my aunts room. Intrigued, I went in my closet which was next to her bedroom, and put a glass against the wall, as I had heard it enhances sounds thru walls. I placed the glass on the wall and could hear the vibration noises and my aunt moaning lowly. I instantly got a raging hardon. Suddenly, I heard her moaning louder and cumming hard, kind of whimpering, "fuck me, fuck me".
She was quiet now and I got back in bed, not just before opening my door a little. I pulled my underwear down by my knees and covered about half of my cock with the sheet. My cock was raging, and I wanted to jerk off so bad, but I hoped she came out and saw it. I don't know how my cock compared with older men, but it was my virgin cock, so I wanted it to be at least seen.
Soon, I heard my aunt's door creak open and she walked by my room and went in the bathroom and shut the door. I wondered if she'd seen it and would tell my mom, her sister. By now my cock was leaking precum.
