This story is one of fiction. Pure fantasy.
I was 19, my sister was 18. She was just starting to blossom, breast starting to fill out, getting her womanly figure. She knew she was going to be wanted my a lot of boys her age, and older too.
I found a small hole in the floor in the bathroom floor one day while I was in the basement, saw this light shining through. So what's a boy to do, go take a peek of course, and man did I get an eyeful. She had just gotten out of the shower and still naked. I could see her breasts and her full bush, just could not get a good look at her vagina. Damn, i was gonna have to remember this.
The basement had always been my hideaway, my safe space. Now knowing I had a way to see my sister naked, I knew I would be spending more time down here. As I was just sitting there running through what I had just seen, I heard the shower start up again, so figured I would take another peek. Now looking up, I see my mother standing there in her naked glory. Her breast sagged a little but not bad, She had a full blonde bush, and oh shit, I just got a peek at my first pussy as she lifted her leg onto the toilet seat. So that what they look like. I could see her labia, full and looking good. I stood there with a huge hard on looking at my naked mother. Two naked female bodies in one day. Now was time to jerk off, and damn did I cum.
A few days later, I got a big surprise as my sister went into the bathroom trying to hide something. It was just the two of us home, so I slipped down into the basement. I wanted to see what she was hiding. I watcher her slip down her jeans and panties and got another peek. This time, I got a bigger surprise, it was that time of the month for her and she had to change her pad. I was rewarded with her standing up to clean and got a peek between her legs. I had my cock out this time and was stroking it as I watched. Was I ever getting an education.
I did peek a few more times over the week and got to see more of what I had seen. The next week was more educational, as it was my mothers time of the month. I was able to get an even better look at her pussy. Damn this was good stuff.
This same week, I got a big surprise, when my sister confronted me and asked if I liked watching her shower. I acted surprised but I think the look on my face gave it away. She said she know I had been watching both her and mom take showers. My face must have been bright red. She told me since I had seen her naked it was her turn to see me naked, so what is a perve to do. I stood there in the living room as I dropped my jeans and stood there in just my tighty whiteis. She tells me they go too, so down they went. I'm now standing naked with a semi in front of my sister. She asked if I got fully erect watching her drying off after her shower and changing her pad. I admitted it did, and that I beat off afterwards. She turned and walked away saying more fun was to come.
I was sitting on the couch when my sister came and sat down next to me. She asked if i had watched her any time this week, and I told her that I had not as I had been busy with school. Now it was my turn to be surprised as she placed her hand on my crotch and told me she wanted another look, but this time she wanted to see it hard. So I told her only if I get a better look at her pussy. Fair is fair is it not.
She stands up and takes off her jeans and panties, so I go and stand up and strip myself. Seeing my sister naked gave me a large hard on. My sister sits back down on the couch and spreads her legs so I can get a better look, and damn did I ever. I kneeled down so I could get a real good look at the first pussy I had ever been this close too. So what is a boy yo do, this close to his first pussy, I reached out and touched her clit which was standing at attention. Her lips glistened. As I touched her clit she jumped but did not tell me to stop. So I touched it again and ran my finger down between her lips, and my finger got wet.
