Turned on by Billy's Scent

It was late Wednesday night and I was all alone. I was 13 and it was the first week of spending the summer with my aunt and uncle in the woods of Pennsylvania and their son Billy was the only child still living at home. He was 17 at the time and I had the biggest crush on him. I wanted to be him so bad. Champion wrestler in his weight class in high school, he was 6'3" of flexing muscle and disarming charm with honey colored ringlets that fell almost to his shoulder, the lightest and softest eyes that were so light blue they looked grey in low light. And he was out seeing Beth tonight. If his eyes betrayed him any more when he told me earlier, I would think I could see them fucking. So I had mixed emotions, I was jealous I was not spending time with him, but strangely I was glad Billy was getting some. This was another time I wished I was Billy. So Uncle George, Aunt Gertrude and I ate early, like 5 o'clock early. I picked at my plate, which was unusual for me. I remember having spaghetti and meatballs, with salad and fruit for dessert. Basically, I was a slob and got it all over me. My aunt said ok, go out and play until dark. So I took Billy's old mountain bike and rode through some trails in the woods for about 2 hours, coming home a little after dark. Uncle George was just coming out to look for me when he asked me if I had any sense going into the woods in the dark. Aunt Gertrude handed me some clothes and told me to wash up and get ready for bed. So I headed to the wash shed that was attached to the garage. Well the first thing I noticed was that the shed was full of dirty laundry. It was wash day tomorrow and Aunt Gertrude had predictably pre-sorted most of the laundry. On the top of one of the piles was a dirty pair of Billy's grey boxer briefs and I couldn't help but pick them up. I put them next to my face and I inhaled deeply, cherishing the feel and smell, as I instantly got hard. I realized I was uncomfortable and I took off my shoes and socks and then my t-shirt and shorts. I was in my underwear and realized that it wasn't so bad sitting on the pile of laundry. And then I realized that it was mostly Billy's dirty clothes. I dove though the pile with his pair of dirty boxer briefs still clutched in my hand. I rolled back in the pile and just bathed in his scent. I was so hard and I needed to feel good. I imagined Billy's hard naked body grinding into mine as I writhed and tried to touch him all over. I turned his undies inside out and I discovered his snail trail, where his dick leaked all day and partly dried into the crotch of the boxer briefs. I slipped my boy briefs off and put his men's boxers briefs on, which were way too big and I had to hold onto his underwear with one hand. There was plenty of space to rub his dampness against my dick and balls. I was rolling through the laundry having a great time and imagined it was Billy wrestling with me, staring me into submission. Pretty soon, the electric tide rolled through me and I convulsed in ecstasy, from head to toe, and I felt like I was covered with soft squishy foam, and felt completely exhausted. I did the crappiest job of washing myself and I dragged my poor limp body upstairs to bed after saying goodnight to my aunt and uncle, who were completely captivated by a movie they were watching.
