Thomas, my first

Some background; this is my first story, and yes it is true. At this time I was 16 and in the best shape of my life thanks to my high school’s varsity swim team. I was about 6’3, brown hair, dark blue eyes, and about 175 lbs.

I had been looking forward to Thomas’ party all week. We had been friends since we were 8, so I got to help his mom plan it. We were going paintballing and then having a sleepover at Thomas’ afterword, which was always fun thanks to his mom’s lax supervision of their extensive alcohol collection. I showed up early and Thomas’ mom let me in and told me to go upstairs to get Thomas. When I opened the door I heard a yelp of surprise. I looked around and saw Thomas in the corner by his dresser with only his boxers on. Now to be honest, I didnt know why, but I had always been extremely attracted to Thomas, so this unexpected peep show was quite exciting for me, although I did have to pretend to be pissed off about the situation for the sake of appearances (I was terrified of people finding out about my feelings for other boys).
After Thomas had gotten dressed, we talked about the usual; how trashed we were going to get that night, how awful our high school’s football team was, and about the amazing ganja we had gotten early that week. When the others arrived we piled into a few cars and sped off for a fun day of paintball. We got back around 9 PM, just as Thomas’ mom was going to be. We immediately went downstairs to lay into the booze collection and play some hoops on their indoor basketball court.
We drank and messed around all night. We were all having a blast running around tipsy acting like a bunch of stupid boys. Gradually people started falling asleep or going home and eventually only Thomas and I were left on the basketball court. When we finished our game we went upstairs to find everyone passed out all over the sectional couch.
