There's a sexual, but also awkward tension as my sister Rachel and I enjoy the pool on this hot July Saturday. While it's not the first time I've seen my sister naked (when we were kids and once when I had accidentally walked in on her changing a year ago), it certainly is the first time we had done anything sexual. This weekend has changed our relationship forever, and as we swim in the pool, there's a sudden switch in our demeanors. Wanting desperately to break the unpleasant silence that has fallen over us since I released my grip from her pussy, I challenge Rachel to a race.
"Sure!" Rachel exclaims. I can tell that she is relieved as we make our way to our starting positions.
Rachel is a great swimmer. While my swimming skills are average at best, my height is what puts me on the same wave length as Rachel. We decide on racing to the end and back, best of 5. I decide to give Rachel a head start on the first race, being the great big brother that I am. I am amazed when I see Rachel spring off the wall and witness her feet flutter effortlessly. Letting her get a head start was a mistake, and I lose the first race by quite a bit.
"Ok ok, no more taking it easy on you," I say to Rachel as we collect ourselves after race #1.
"Oh please, I could beat you in my sleep," Rachel snaps back.
While I win the next race by a close margin, sure enough, Rachel wins the next two and claims victory. It had been awhile since we raced liked that, and as Rachel makes her way out of the pool and heads to the diving board, I can't help but be impressed by my baby sister.
Wasting no time, Rachel jumps up onto the diving board, waiting till my eyes lock onto her. She quickly turns her butt to me, brings her two hands to her bikini bottoms, and flashes me while laughing to herself. She quickly turns back around. In typical Rachel fashion, and with a running start, Rachel springs from the diving board's end, wraps her body together, and does a powerful cannonball. Her butt hitting the water creates a unmistakable "POP" sound, and I can't help but laugh. Rachel eventually comes to the surface a few yards from me in the shallow end, and immediately joins me in laughter.
"Be careful with that booty of yours," I say, "You're too old and curvy to be pulling stunts like that with that thing."
At this, Rachel lunges towards me playfully. "Excuse me but who do you think you are!!" Rachel exclaims. Rachel grabs my head with her hands, trying her best to pull me under the surface of the water. As she does so, my face grazes her breasts, my nose clipping the underbelly of her bikini top. Whatever tension that was present after we "applied sunscreen" was now gone. I'm able to break away from Rachel's grasp, and with Rachel now in a fighter's stance with water halfway up her body, I thrust my body towards her, grabbing her calves under water with both of my hands. This causes Rachel to lose balance, and before she knows it, she's struggling to stay above water.
I laugh as I have my way with Rachel. While she may be the superior swimmer, I let her know that I'm still her big brother. We go about this underwater wrestling match for a few minutes, eventually ending up on the pool stairs, with water up to our torsos now as Rachel directly to my left.
"Gosh, I missed spending quality time with you like this," Rachel tells me.
I bring my left arm around Rachel, grab her by the shoulder, and bring her in closer. "You're telling me" I kiss Rachel on the head.
"I really do love you," Rachel says. "And I know we shouldn't be doing what we've been doing, but like, you're my brother and I just feel comfortable with you. More so than any boy that I've been with."
I let Rachel's word resonate for a few moments. Looking straight ahead, words of my own eventually come to my mouth, "I love you too. And yes, while what we are doing may be 'wrong,' can't we just do it without...thinking about it? Just this one time. What does one weekend like this really matter in the long run? You're my sister, and you'll always be my sister, and I will always love you."
"Exactly! Honestly, I feel closer to you now than I ever have before. It's not like we're going to be doing this for the rest of our lives. It's just one lousy weekend without Mom and Dad."
Rachel wraps her legs across mine as I cling onto her shoulder. She rests her head on my shoulder as we sit in silence. I rub her upper arm with my left hand. All is right.
"I need to pee," Rachel suddenly lets out. I laugh at how quickly the tranquil moment turned.
"Just pee in the pool, I won't tell mom and dad." We both laugh in unison. If only that was the sole secret we now shared.
"I get nervous peeing in front of people!" Rachel lets out.
"The hell you do. You just peed in front of me this morning!"
Rachel laughs, "Ok yes, but I REALLY needed to go then. But I guess I really need to go now too."
I bring my left hand down from Rachel's shoulder and grab her butt. Rachel lets out a yelp as I prop her up on my lap. It feels so nice to have Rachel's butt in my grasp once again. When we had been wrestling moments ago, I was able to grab around her waist as her butt pressed up against my swim trunks, and since then I had been waiting for the right time to feel her butt fully with my hands.
"Ok you seriously need to watch where you put your hands or you're going to make me go," Rachel explains in a childlike, excited voice.
As my left hand rests on Rachels left hip and my right on her right thigh, my penis begins to break away from the constraints of my swim trunks, and by the look on Rachel's face, she notices.
"Oh does that turn you on now, you sicko?" Rachel asks.
"You turn me on," I respond.
Rachel wraps her right arm around my shoulder, her perky boob now clinging to my chest, with only the bikini fabric separating our skin. Rachel takes her hand and pulls the back of my hair with it. I lean back playfully. I love having my hair messed with.
I lean in for a kiss but Rachel backs off and starts to giggle.
"What is it," I ask.
"Can I please pee in the pool?" Rachel asks through her giggles. "I really need to go."
"Oh come on, really? We're not kids anymore! I have your butt to prove it." I squeeze Rachel's ass. My hand is only able to grab onto so much at once, and I'm forced to squeeze again to get the rest of it. She squeals and laughs at the same time as she leans further into me.
Using the squeeze of her butt as an excuse to reposition, Rachel sits up slightly closer to my knees, swings her left leg around so that she is now facing me. Her legs are on both sides of me with her knees on a slight angle towards the sky. While our bottoms halves are still submerged in water, I look down and can see my boner up against Rachel's bikini bottoms. Her bottom's get pressed up tight as she scoots slightly closer to me, and I can make out the lips of her pussy form.
"We may not be kids anymore, but I did see your butt this morning in the shower, and I haven't seen that since we were kids," Rachel says to me through a smile.
"Fair," I say back to her.
Rachel wraps her arms around my neck playfully.
"Fine, I can hold it. I promise," Rachel says.
"Well that's good because I'm enjoying how your sitting right now."
Rachel lets out a quick laugh. "Ok that's good because i didn't know how to make a move on my own brother and that's the best I came up with." My hands find their way through the water to rest on Rachel's thighs. She grabs them immediately and places them onto her butt.
Rachel leans in and our lips meet. We both realize immediately that neither of us want to stop, so we keep going, her hands held still on my neck, my hands caressing her ass.
We make out for a few minutes before our tongues get involved as they begin to intersect throughout our exchange. I can tell that Rachel has nervous butterflies fluttering throughout her body, but when I first stick my tongue in her mouth, she becomes a bit more relaxed and immediately returns the surprise. Her hands begin to rub the back of my head, brushing past my hair.
After we finish what we think is our last kiss, we exchange smiles as we look into each other's eyes. Rachel looks down at my lips and immediately leans back in. She begins to slowly rub her pussy up against my erect dick as we make out. Our kisses get more aggressive as Rachel's slight throbs pick up a bit more speed. "I can't hold it," Rachel whispers quickly through our saliva filled kisses. My dick and balls gradually become warm as I feel the stream coming from Rachel's urethra against my dick. I come to the realization of what is happening as Rachel's tongue is in my mouth. She bites my bottom lip on her way out and smiles through it as I follow her tongue back into her mouth. I press upon her butt, nudging her closer to me. "Sorry," Rachel squeals quickly before going in for another kiss. I feel the warmth of the water disperse out into the open.
I place my feet steadily on the pool floor and pick Rachel up by her butt with her legs now clenched to my sides. I walk her over to the opposite edge of the pool, and immediately feel the coolness of the water take back control. I press her up against the wall of the pool. I kiss her dimples as she lightly kisses my neck. I feel her tongue penetrate from her mouth as she makes her way up to my ear where she nibbles on it slightly.
I place my hands on her sides now, forcing her to clench her legs even tighter around my waist. I grab her right pony tail and pull on it, forcing her to release from my ear. She smiles, and her dimples become even more pronounced. I can't help but grab her by the back of the neck and kiss both dimples in rapid succession. I smile back at her and our foreheads rest on one another.
Neither of us want to stop, but being confined to a pool only allows us to go so far. I slowly separate from Rachel and begin swimming to the deep end. Rachel follows behind, getting a piece of my butt as I dive into the water.
"Sleep in my bed tonight?" Rachel asks anxiously once I arrive to the surface, my back to her.
"Yes. Of course." I smile back at her. "How bout inviting Bobby over to hangout?" Bobby is a family friend of ours that is a few years younger than us.
"Nah, they're on vacation. I can send out a few texts to see who's around."
"That sounds great," I respond.
We enjoy the sunshine and each other's company for the rest of the day, flirting playfully here and there. I now sit back in my lounge chair and think about the night to come. I feel my dick gradually becomes hard again in anticipation.
