When I was 15, I used to spend nearly every summer day at my best friend Buddy’s house, Since, they had a pool, We didn’t! We had a lot of fun, riding bikes all day in the woods behind our subdivision, teasing the girls and swimming. All the normal 15 year old summer stuff. Buddy was a great friend, his sister, Dawn was OK too, not like most my friends sisters. The only bad thing about Dawn was she was around 150 standing 5 feet 4 inches tall, not one part of her firm I don’t think. But she was funny and only two years older than us, she always cooked us something when we asked, so Buddy and I had it beat.
We were friends throughout Jr. High and High School until well after we Graduated, Our first summer off, Finally! We went swimming one day and Dawn joined us in her big one-piece swimsuit, it did nothing to hide the size of her nipples OR her fat ass. We splashed around, seeing who could hold their breath the longest, shit like that, having a good time, trying to beat the hot summer sun.
After about an hour, I had to pee, so I went to the upstairs bathroom. As I was taking a leak I looked out the back window and saw something that shocked the shit out of me. Dawn was kissing Buddy and had her hand down the front of his swim trunks! DAMN, I thought to myself, I know that’s wrong, but I sure was wishing it were me! I’d like someone besides myself to play with MY dick. I stayed inside a little longer than I normally would have so I could watch some more. My Dick was hard as a rock now.
I had to jerk off, I looked in the laundry hamper and found some of Dawns huge panties, I grabbed them, and put them to my nose inhaling her fragrance. There was a huge stain in her crotch area, kind of yellow. I wasn’t sure if it was pee stains or what, but I didn’t care, they are softer than my hand. I wrapped them around my dick, jerking like a mad man, not wanting to get caught.
I came in less than two minutes, leaving a large spot of my thick cum in her panties. Then ran back outside loudly announcing my presence as I ran around the corner. They acted like they had just been swimming nothing happening that I had seen.
Buddy and I swam around as Dawn said she was done for the day and went inside. We messed around another 30 minutes and went in to get something cold to drink. When I looked at Dawn she gave me a strange look. I shrugged to myself wondering what the heck that was about. Buddy ran upstairs to change and as I was sitting at the kitchen table, Dawn walked over and sat across from me.
“I saw what you did this summer!” she said.
“Yeah I saw that movie!”
Then she looked me right in the eyes, and said, “No, I saw what YOU did, in my panties!!!!”
Holy Shit Batman, Shit, I never thought about her doing laundry today! I squirmed around on the seat.
“Uh, what?” I said innocently.
“I know it was you, because those were the panties I had JUST taken off to go swimming! And there wasn’t any Cum on them when I did!”
Well shit, she had me now, what could I do?
“Uh, Uh, I didn’t mean too.”
I mumbled, then I thought, HEY, Wait a second, I wasn’t the one letting my sister play with my dick and kiss me! The tables had turned now.
“I wouldn’t have done it if I didn’t see you jacking Buddy’s dick in the pool and kissing him!”
Her eyes got big as saucers.
“I did not! Uh, we were chasing each other and I fell on him that’s all!”
A huge blush rushed across her face.
“Yeah, Yeah, and your hand just happened to land on his dick huh? From the inside of his suit, yeah I can see how that would happen Dawn!” I grinned an evil grin at her.
“OK, OK, your not going to tell on us are you?” she was looking scared.
“Hmmmm, I don’t know Dawn, that is wrong you know. I mean he IS your brother, if it was someone else maybe it wouldn’t be so bad, but you Brother, Idunno!” I told her with my grin plastered on my face.
“I’ll do anything if you won’t tell.” She was near tears now.
