Skinny dipping with my sister [fm] [incest]

Lmk if you guys want to hear more-apologize for any poor grammar.

So I was at home with my sister. We have a pool at our place. So one night no parents were home and I guess she was feeling like going for a swim. We were drinking a bit. I saw her go into the backyard wearing a one piece suit similar to the one I posted her in. I was in the kitchen with the lights out watching tv. I was just watching her smoke and chill for a while until she got up and jumped in. I got kind of excited watching the back of the suit wedge deeper into her ass every time she dove in. I got hard and couldn’t take my eyes off her. I pulled my pants down in the kitchen and started to play with my cock. It felt so wrong but it was so hot. I felt like such a gross pervert masturbating to my own sister. I watched her walk closer to the backyard door so I put my cock away and acted like I was watching tv.
“Hey bro wanna come swim?”
At first I was thinking no but than I realized that it could be fun. “Yea sure”
So I grab swim trunks and walk outside with her. Her ass was swallowing the back of the bathing suit and I couldn’t help but stare at my sisters ass. We were both pretty buzzed but definitely not full on drunk.
Standing by the pool without saying anything she peels her swimsuit down exposing her tits. They were small with puffy nipples. She goes “I’ve never gone skinny dipping before do you want to try it”
I was like yea sure. She continued to peel off her suit than quickly jump in. I could see her pussy quite well. It was poorly shaven, with a few dark hairs showing closer to her thighs and small razor marks around her pussy. I could feel myself growing in my pants so I decided to get naked before I was totally hard so she wouldn’t think I was turned on. As I watched her swim I started to take my shirt off. She stopped swimming and watched me as she stands in the water. She was on her phone but I could see her eyes looking at me. After I take my shirt off I pull my shorts and underwear down exposing my slightly erect penis to my sister. Her face turned bright red. I wanted to jump into the pool before I got hard so she wouldn’t think I was horny for her. So naked, I start walking towards her in the pool. The entire time before I could jump in she was staring at my cock. Like pretty obvious. After I jumped in we swam around and drank a bit. She would get out to walk to the diving board to do a dive back into the pool. Watching her wet naked body going in and out of the water was so hot. I could feel myself getting hard under the water.
She jumps back into the pool and playfully swims around.
“Why don’t you show me one of your dives”
She goes.
I’m immediately nervous that she will see my erection and react but the thought of being exposed to her and showing her my body was such a turn on.

I decided why not So i turn my back to her and climb out of the pool and walk to the diving board. I get to the diving board and turn to face her presenting my naked body and erection to my little sister. I start to bounce on it and get ready to jump. But before I could I heard a gasp
“Oh my god” “your seriously hard right now?” She started laughing as I jumped in. She swam towards me giggling
“Why is it hard?? Are you like turned on right now”
I was like “yea sorry I can’t help it”
“Your so gross, I’m your sister yk”
“I mean swimming naked was your idea”
She giggles a bit and climbs onto a floating seat in the water,straddling it blocking my view of her vagina. I could still see the creases in her thighs and her razor marks from shaving. She passes me one of the floating seats. I hesitate for a moment
“Come on I’ve already seen it before”
I climb onto the floaty facing my sister. My testicles hang down and rest on the plastic raft and my erection points straight up. Her eyes are fixated on it.
“Can I touch it” she goes.
My face gets red and slide myself forward towards her to make my parts more accessible.

She floats up to me getting really close. Our legs touch and she leans over and grabs my erect penis in the right hand. She giggled a bit and started slowly stroking it.
After a few minutes of silence she throws a leg over mine to keep the floaty from getting too far. As she wraps her leg around mine and gets closer
She looks into my eyes and goes “ I never guessed my brothers dick would be this big” and started giggling and I could feel myself about to explode
She kept giggling and staring at my cock. I reach out to grope and play with her tits and i start to squirm. I can’t hold it much longer. I moan softly as my hand wonders to my sisters pussy. She opens her legs as my hand glides down. I could feel the stubble and hairs she missed while shaving. I reach down farther to feel her warm wet lips. I hear her release a small moan than it happened. I tense and groan as I shoot cum all over myself and my sister.
she laughs as she pulls her sticky hand away. She licks one of her fingers than quickly rinses her hand in the pool than grabs her swimsuit off the ground and walks back into the house. I sat in the floaty while I stare at her ass as she goes back inside.
