Pool time

The week passes by quickly. Diana has been busy with a research paper, so I decide not to add any new changes for now. Best to let her focus. Besides, her clacking away on her laptop while she’s laying down gives me the best view of her cute little ass. And the best part, she doesn’t care that I’m visually groping her. In her head, the fact that she sleeps in my bed, snuggled up in my arms naked is a fact of life as normal as the sky being blue.

Friday night arrives and I just want to take a moment to relax. I’m headed home so I text Diana, inviting her to the pool. She replies that she and Amber are planning to watch a movie tonight.

Sigh, maybe another time, I think as I read her text.

I get home and to my delight, Diana is in the fast learning machine. Maybe I can make this work.

I quickly run over and see the program about to end in 2 minutes. That’s weird, Diana seems to be learning about lesbian “pleasure” positions. Maybe I’m crashing more than a normal movie night. It’s okay, I’ll still let them have their fun.

I head over to the terminal:

You want to change plans and invite Amber to the pool instead

Proper swimwear consists of being totally naked

Amber shows up shortly after. I send Diana away and quickly program the same thoughts into Amber's mind.

We head to the pool fully dressed but to my pleasure, the girls quickly undress once we arrive.

Luckily, I know that the other tenants at this apartment complex don’t use the pool that often.

I’ve seen Diana and Amber nude before, but there’s something about watching two gorgeous women undress in front of you as if it’s the most mundane thing in the world that makes it something special.

I can see how cold they both are with their sharp nipples piercing the cold evening air, so we hop in the pool.

It’s like a normal pool party, besides the constant boner fuel that lay in front of me.

Diana and Amber are both arguing about which of them can hold their breath for the longest, so they have beg me to judge their competition. They both go underwater, giving me a moment to appreciate their bodies from the surface. They can both hold their breath very long for whatever reason. Staring at Ambers juicy ass and Diana’s nice tits, I naturally begin jerking my cock under the water. They’re closing their eyes, but I can see them wrestling eachother under there, trying to get the other to unsubmerge themselves. I watch their ass and tits jiggle in slow motion. I don’t know who started it, but soon Amber’s finger is inside Diana’s pussy.

This pushes me over the edge, and I accidentally nut. Lines of cum shoot at them and hit their faces, but they are none the wiser. Strings of semen float around them in the water. When they finally can’t take it and must come up for air, I see bits of my cum stuck in their hair.

They don’t notice and just start laughing.

“THAT’S NOT FAIR! YOU CHEATED!” Diana screams playfully.

You notice a bit of your cum has made it into Diana’s mouth.

“We’ll you never specified the rules, so I win,” Amber says smugly.

We spend the rest of the night in the hot tub, where I notice Amber and Diana playing with each other's pussies. They are trying to be discrete, but it’s painfully obvious. They were both closing their eyes and taking in the moment, giving me the opportunity to watch for all of my desires. I see Amber remove her hand from Diana’s crotch, so I take my chance. I reach in and replace Amber at my sister’s pussy. I rub around, making it seem like my hand is Amber’s. Diana doesn’t seem to notice. She closes her eyes tightly, letting out a small moan by accident, and I feel her slimy cum shoot at my hand.

I quickly remove myself from Diana, as she opens her eyes and smiles at Amber.

Amber stays the night, taking Diana from me again. I really need to do something about that.

I wake up to my alarm and see that Amber is long gone. I head over to the lab and Diana is, like always, using the fast learning machine to fulfill her intellectual pursuits.

Her mind looks tranced. Her mouth is open, drool running down her lips and forming a puddle on her tits. I do her a favor and wiping off, making sure to sink my fingers into her meaty flesh.

I’m tired of not being able to get off to my sister despite her walking around like a whore, so I type:

Because siblings are comfortable being naked around each other, masturbation is not considered taboo.

Exhausted from having to wake up to catch Diana in one of her study sessions, I head back to bed.

I wake up around noontime and I hear Diana watching tv in the living room. I slowly get up and ready myself for the day.

I enter the living room. Diana is on the couch, but something is off. Instead of a movie playing on the TV, it seems to be another of Amber’s sex tapes. You walk up and see Diana’s hand is buried about two inches into her wet cunt. A dark spot has formed between Diana’s legs, as well as a puddle of cum that seems to be growing.

“Uh Diana, what are you doing?” I ask, not knowing what else to say.

“Oh I’m just getting myself off real quick. Amber sent me this video a few hours ago and thought I’d get a quick rub in before I start work. Want to join?” Diana asks nonchalantly.

“Um okay...” I say, sounding unsure of myself.

“What’s the matter with you. Looks like you never seen a girl touch herself before,” Diana says teasingly, her fingers still thrusting in and out of her moist pussy.

I awkwardly sit on the couch next to your sister and start dry stroking your dick.

“Hey, you want some lube or something?” Diana asks as she stares at you stroking your cock like it is a normal sight.

“Uh sure,” I say, not knowing what to expect.

To my shock, Diana rubs her hand down her meaty snatch, making sure to collect as much of her cum as possible. She then runs her hand across the couch between her legs. Soon, she had a handful of fresh lady juices, straight from the source.

She reaches her cum filled to me as I awkwardly meet her in the middle. She rubs her hands onto mine and pulls away, a string of her cum going from her hand to mine until it finally snaps. With nothing else to do, you lather her still warm juices on your cock and watch the tv. Diana goes back, this time rubbing her clit.

On the TV, Amber is taking a massive cock up her cunt, with the camera angled to show a closeup of her spread ass. I can hear her screams in the background emanating from the TV speaker. A mixture of her cum and the cum of whoever she is fucking seems to ooze out of her pussy with each thrust.

I don’t know what to watch, Diana ferociously fingering herself in person or Amber taking a massive cock up her lady parts. I take a moment to appreciate Amber's fat ass jiggle with each thrust of the penis. Then, I notice Diana’s tits jiggle with each flick of her finger.

Suddenly I cum, accidentally getting some of my semen on her leg.

I expect her to be outraged at me, but to my surprise, she doesn’t care. Without removing her dominant hand from her pussy, she uses her other hand to wipe your cum off of her legs. She then wipes her hand on her chest, like a big meaty napkin.

Your cum spread across her perfect tits.

Almost on queue, Amber begins to cum. You watch the TV as she moans and squirts, leaving droplets of liquid on the camera lens. The cameraman removes himself from her pussy, and zooms in on a closeup of her still dripping cunt. He then moves his face in, making sure not to waste a drop of her delicious liquids. Diana has had enough, as she moans in ecstasy and squirts all over the couch, overflowing onto the floor.

Not much happens for the rest of the day. We go to bed, and I am quite certain I feel Diana's hand moving around her lower crotch region. I push my erection onto her ass, and she seems to reciprocate.
