I (M22) make my way into the kitchen, where I'm greeted by my sister (F20), hunched over the stove top as bacon sizzles on the pan in front of her. Since I had gotten out of the shower and changed into some clothes, my sister Rachel had done the same. She was now wearing a cut off t-shirt and short athletic shorts, her butt really popping as she leaned up against the stove on her tippy toes. Rachel was the baby of the family, and my parents and I treated her as such. Standing at 5'4", Rachel has dark brown hair that is naturally straight. Today, however, her hair is up in two braided pigtails. The look really fit her well, and as I make my way around the kitchen island, the dimples on her cheeks glisten as she sings lightly to herself as she multitasks, cooking up a breakfast consisting of eggs, bacon, sausage, and toast, making my mouth salivate as my nose takes in the different scents.
I come up from behind her and pull lightly on both of her pigtails, something I have always playfully done whenever she puts her hair up like this. She stops singing for a second as her head tilts all the way back, her smile coming alive as her dimples become even more pronounced. I look down at her as she smiles back at me. I pull a little tighter now as she lets out a light gasp.
"That's what you get for earlier," I tell her, half joking.
Rachel lets out a laugh. "My curiosity got the best of me, what can I say."
"Imagine what mom and dad would say if they knew we showered together??" I think out loud.
"I can't even imagine," Rachel says immediately. "Let's just keep that between us, what do you say?"
"No duh," I respond back, smacking her butt playfully with my back hand as I head to the fridge.
"And I'll be sure to keep your big you-know-what a secret too..." Rachel says softly.
"About that," I begin to stutter my way towards an explanation.
"No, no. No need to explain," Rachel insists. "It happens, it's only natural. Don't worry about it."
"Well thanks," I say.
"I would have been the same way if I were in your shoes," Rachel jokes as she clasps her hands onto the countertop in front of her and gives her butt a shake.
I laugh it off and shake my head. As my dick begins to get hard as I stand there, staring at my sister's butt, I decide to go sit down at the kitchen table to calm the blood rushing towards my penis. Rachel goes about cooking breakfast.
We eat breakfast in peace, looking outside at the warm, summer day. We decide that it's a great day for a pool day, and contemplate inviting some friends over. We decide against it. Why not just enjoy each other's company, we think aloud. After breakfast, we go to our rooms to change into our swim wear.

I come outside and am immediately greeted by the hot, summer sun. I don't see Rachel outside just yet, so I decide to clean the pool while I wait for her. I'm walking around the pool, using the net to fish out any unwanted leaves and debris, when I hear the sliding glass door glide open. Out comes Rachel in a bikini that I had not yet seen before. The top is white and the bottom was a light purple color. While Rachel has a very plump butt and semi-muscular legs, her boobs are less than average size, but perky nonetheless. Her torso is toned in an effortless way. Rachel eats what she wants, when she wants, and thanks to a fast metabolism much like my own, she always seems to stay fit. Her body and her looks are desired by her friends and even my girl friends.
I'm glad to see Rachel holding onto a bottle of sunscreen, and I desperately ask her if I can use it. She throws it my way, which surprises me. I was expecting her to use it on herself first. Anyways, I lather myself up and ask Rachel if she could get my back for me. She walks over and applies a generous amount to my back. I squirm slightly, as it is very cold to the touch.
Rachel giggles to herself. "Quit being a baby!"
I ignore her as she continues to spread it across my back and sides. Her hands really do feel nice on my body. She finishes up and begins to apply sunscreen on her own body. She squirts out a generous amount on her left hand and hands the bottle over to me. No words are spoken, as this is a customary routine for us on a hot summer day like today. However, something seems to be different today. I don't know if it's because our parents are away or if it's because of what happened last night or in the shower this morning, but the sexual tension has been rising in me. Not sure if Rachel is feeling the same way, I decide this is my chance to find out.
I take the sunscreen and spread it in my own hands before applying it to Rachel's skin. I make my way around her shoulders as she stands, staring straight ahead. I get underneath her top bikini strap, making sure that I get every inch of her skin. As I'm doing so, my hands spread their way to her sides, with the thin bikini strap gliding across the back of my hands. I make my way to her side boobs and use that as my stopping point as I spread the sunscreen into her olive, smooth skin.
I make my way down to her lower back and slip my finger tips just inside of her bikini bottoms, moving my way across the top fraction of her butt. That's all I need in order to feel her luscious butt, and I immediately start to feel the blood rush to my lower half. I move to her love handles, moving both of my hands up and down her sides. At this point I see her hands clench the sides of her legs, her finger nails indenting into her skin.
"Can you get the back of my legs too?" Rachel says desperately. I can tell she doesn't want me to stop.
I squirt out another bit of lotion and get on my knees as Rachel stays standing. I begin to apply the lotion to Rachel's calves and hamstrings. I can feel the different muscles of her legs as my hands glide up and down. I look up at her butt, which is hanging out of her conservative, light purple bikini bottoms. It certainly isn't a thong that she is wearing, as my parents would not allow that. It'd be thought of as covering up a lot by today's standards, but her butt still manages to break out of the constraints of the tight, but breathable, bikini bottoms. Thin, tiny stretch marks are visible on her hips, but if you weren't as close as I am right now, you wouldn't even notice.
I can't take my eyes off of her bottom. My hands naturally glide up and I suddenly find myself cupping the bottom of her butt cheeks, applying the sunscreen in and out of the crevice that naturally forms in her bubble butt.
"Is this ok?" I ask, my voice slightly shaking.
I look up at my sister and notice that her eyes are closed. She seems to be in a trance.
"Yes....yes. Thank you. Ummm, just make sure you get it all," Rachel responds after a brief moment of silence.
I lean in a little closer and move my hands in circular motions around the sides of her butt. Her butt jiggles as I begin to move a little faster, wanting to make sure that I blend in all of the lotion.
As I'm spreading it in with my left hand, my right hand rested on my sister's hip bone, I feel the sudden touch of my sister's hand on my right. She clenches my hand and moves it so that it is directly under her bikini bottoms, gripping onto her bare butt. "I said make sure you get everything," Rachel says to me.
At that moment I take both of my hands and begin to go up and down her whole butt, running straight through her bikini's fabric, from the top of her hamstrings to her lower back. My fingers slide along her butt crack, and I feel the warmth and sweat starting to form in between her butt cheeks.
"Let's take this off," I say as I untie her sides without asking.
"Mhmm," Rachel moans. I look up to see her biting her bottom lip, her eyes still closed. It was at this moment that I knew I had her.
Her bottoms fall to the ground, and I have a clear view of her bare ass. As I look up, I can see her pussy lips protruding slightly, but her butt is so big now that nothing is constraining it that it covers most of her pink pussy up. I take her right leg and spread it slightly as my hands make their way up and down the inside of her thighs. I feel a wet stream going down her left thigh and spread her leg a bit more so that I can have a better view of her pussy lips. As I'm gripping her left leg, stroking it up and down with both of my hands now, the lotion begins to mix with the juices flowing out of her pussy, creating an oil-like substance. I switch to her right leg, stroking it with my big hands. I'm able to wrap my hands fully around her leg above her knee, but as my hands make their way up, they are forced to separate. My left hand continues up the inside of her leg, my right hand gripping onto her butt, releasing once I have a whole handful of her perfectly shaped ass. It jiggles upon release, and I can't help but take a small bite of her right butt cheek. Rachel gasps and then laughs, breathing heavily now.
"Now that's payback from you seeing my dick earlier," I say.
"Your HARD dick," Rachel clarifies. "And it was worth it."
Rachel then reaches between her legs and grabs my left hand and brings it to her pussy, guiding my entire hand across her pussy lips. My hand is immediately drenched in her juices. I feel her pubic bones and her tiny, protruding pubic hairs as my hand slides across her pussy. I keep rubbing, eventually stopping as I clasp the front of her pussy, covering up where her bikini bottoms used to. I slowly stand up, still clasping my left hand between her legs. Once I am on my feet, I slowly slide my left hand across her pussy and between her butt crack, passing my fingers along her butt hole on the way up. The combination of the lotion, her pussy juices, and the sweat between her butt crack make for a slippery concoction. I caress her abdomen with my right hand and slowly insert my wet fingers of my left hand into her mouth. Her eyes are still closed as I wrap my head around to see her face. She welcomes my fingers and immediately cleans them up with her soft tongue.
"Mmmm" Rachel moans once more.
I slide my fingers out of her mouth and her tongue follows, begging for one last lick. I take her by the hips to align herself so that we are now facing each other. My hard dick is pressed up against her left thigh. There is no point in hiding it now.
Rachel finally opens her eyelids, and our eyes meet. She smiles in a sexy way, and I return the grin.
"I think I got it all," I say to her.
"I think you did..." Rachel responds.
We lean into each other and embrace in a series of kisses that lasts anywhere from five to ten seconds.
I pick up her bikini bottoms and hand them to her. She grabs them with her left hand as her right hand presses up against the dick protruding from inside my swim trunks.
She puts her bikini bottoms on as I watch, noticing her pussy juices still streaming down her leg. She then jumps into the pool and I soon follow.
