Trent

I walk out back from the beach house, my parents are are out for the day , leaving me and my sister to our own devices. 

I just woke up, taking advantage of my final summer vacation before starting college, and sleeping in. It’s a little after noon and I walk out , looking out at the beach , my eyes zeroing in on the ass of the girl bent over laying down a blanket. It’s a nice ass, a really nice ass , my cock thinks so too as it twitches watching the hot pink bikini bottoms ride up between the girls ass cheeks. 

I adjust myself in my sweats, and then do more than adjust as I grip my dick as I stand at the edge of the deck looking down at the hot girl. 

Then she stands and turns, and my eyes get a side view of a nice full set of tits, strung tight in the little matching bikini top , a half second later I drop my hand from my cock and curse as I see her face. 

“Jesus Christ” I say with disgust as I realize I was just getting hard for my sister. 

“For fucks sake” I scold myself. “Really Trent?” I mutter out loud to myself. 

I’m about to turn away and go try to pretend I did not just get pervy over my own sister when her hands raise behind her back and she starts to adjust her top. My eyes won’t fucking move. 

The deck sits up high, three flights of stairs take you down to the beach, and then the beach spreads out towards the water. And I’m standing up here, watching as my sister Tiffany doesn’t adjust her bikini top. But takes it off. 

My mouth falls open and my dick gets hard as fuck as I stare at her bare tits. Fuck. They’re nice. Really fucking nice. 

I watch as she lifts her hands to her hair , pulling slightly on the messy little bun to tighten in and then she’s grabbing a bottle of sun screen and starts to spread it over herself head to toe. 

Look away. Stop fucking watching your fucking sister you pathetic fuck , I internally yell at myself as my eyes watch her hands rub the white cream all over her neck and chest and arms. Watching her hands cup her tits as she massages it into them and then some on her stomach. I want to cum all over her my dick says as it begs me to stroke it and my mind argues Fuck! No! That’s your fucking sister!

My dick wins. I move my hand over my sweats and grab it , I give it the slightest of strokes, telling myself I just need to relieve a bit of the pressure. 

“Fuck” I exhale. “God damn” I mutter as my eyes go all over her fucking body. 

It’s not that I’ve never noticed my sister was attractive. Our entire family is good looking.  It’s also not the first time I’ve noticed her body either. Thanks to my friends that like to piss me off by telling me how hot she is. But I’ve never looked at her body…like this. Never, wanted her body underneath mine. Fuck. I feel so fucking sick and disgusted , yet my hand reaches into my sweats now and strokes my bare cock as I watch her finish applying the sunscreen and then laying down facing the water on her stomach. 

My fist is working quickly, and I can’t believe how fucking hard I am. This is so fucking wrong. 

I stare at her skin, that fucking ass , and I keep stroking. 

“Fuck Tiffy” I groan as I imagine her without those bottoms on. Imagine her rolled onto her back with her legs spread, I bet she has a hot fucking cunt. I bet it’s nice and pink, bet it’s…fuck …stop it. I battle with my mind , but my fist keeps pumping as I look at her laying there. 

I imagine that ass raised , on her hands and knees , with her face to that blanket and me taking her from behind, slapping my hips against her as I drive my cock home into her pussy, nice and fucking deep. I imagine the way her ass would bounce off me. 

“Fuck yeah Tiffy” I groan through my teeth. Guess I was doing this. Guess I was going to jerk it to my little sister. 

She’s only a year younger than me, and I groan as I imagine her in all the outfits I’ve been able to ignore. Now my mind revisits the way she looks in her yoga pants. The way she looks in tiny shorts and tight tops. The way she looked in flirty little fucking sundresses. Imagine her in the panties and bras that I see ontop of her laundry baskets. 

“Fuck, I want you Tiffy” I groan as my hand brings me to edge and I lower my sweats, standing there shirtless as I pump my cock. 

“Fuck, I want you” I groan louder as I bring myself to orgasm. My cum shoots hard off the edge of the deck through the wooden slats. 

I picture my cum all over her, groaning as my cock spurts the last drops of cum as I also imagine my cum inside her. Cumming in my sisters pussy. 

I exhale with relief as my dick finishes cumming for my sister. Instantly I’m flooded with regret and shame and fucking disgust. 

“Fuck” I grumble, shoving my dick back into my sweats, turning and walking back inside. 

“Never again.” I growl. “Fuck” I shake my head and walk to the kitchen and try to ignore the fact I just jerked off to my fucking sister.
