Amber

I wake up to a new day. It is relatively early, I still feel Diana's warmth lingering in the sheets next to me. I hear two voices in the kitchen so I eagerly get up and almost forget to put on pants. I walk out the door and am greeted with Amber's juicy ass staring at me. She is wearing yoga pants, and I can just about make out the outline of her panties.

"Hey Amber! Long time no see!" I say as I greet her.

"Thomas! You've grown so much!" She says as she pulls you into a friendly hug.

"Okay. Settle down it hasn't been THAT long," Diana butts in jokingly.

Diana wearing clothes at home catches me off guard. Though, if all goes according to plan, she won't be for long.

Me and Amber catch up for a little bit, Diana staying close to make sure that there is no flirting going on. Luckily, this was accounted for.

"Hey sis, do you mind getting some pizza from the deli?" I ask.

I make sure Amber stays looking at me so that she doesn't notice Diana playing with her tits.

"Uh sure," Diana hesitates. She doesn't want to leave Thomas alone with Amber, but she has ****.

Soon enough, Diana leaves, obviously in a hurry to be back quickly. Amber is confused as to why we all can't go, but she doesn't think much of it.

I break the silence: "So Amber, did Diana tell you about the secret project she was working on?"

"What secret project?" Amber asks, obviously curious.

"Oh nevermind then," I say quickly, as to seem as though I am hiding something.

"Oh shut up Thomas. We both know you want to show me. Just get it over with!" Amber says playfully.

"Okay fine. Its a fully immersive virtual reality system. Its in the really early stages but it works," I say, lying so that I can find a way to get her into the machine.

"Oh really? I've never heard of it," she says sounding hesitant to believe you.

"Ah. Her competitors are making it hard for her to get out of the testing phase. Trust me. It's something you just have to experience," I say.

That seems to be enough to catch her interest, so I bring her to Diana's lab and set her up into the system.

Amber is soon under a trance and I take the opportunity to warp her perseption of truth:

You and Diana are besties. You are so close that you are completely nude when at each others' houses.

Though you aren't romantically attracted to Diana, you are sexually attracted to her.

You are as close with Thomas as you are with Diana. You have no problem seeing each other naked or aroused. In fact, you often send him nudes so that you can rate them before you send them to other guys. You take his opinion on your nudes as truth.

You are very caring, so if Thomas mentions that he is cold while he is sat down, you will sit on his lap.

You will remember this as a super real virual reality experience. You know it is secret, so you will not tell Diana that you used it.

While Amber is not a slut or anything, I know from ease-dropping on Diana's phone calls that Amber is very sexually active. These facts should be reasonable for her mind to accept.

Amber wakes up and is esstatic. You take her to the living room while she strips her clothes. You follow her lead as you begin to take off your pants. Soon, you are both sitting on the couch in the nude. You have drooled over Amber's body for as long as you remember, and now, she is sitting in your living room expressively recounting the adventure that she [didn't] have in virtual reality. Though her tits are a lot smaller than Diana's, her expressive body language still makes her chest jiggle. You almost have a heart attack when she jumps up repeatedly and does a 360 to demonstrate the part of her adventure where she took off in a rocketship. Her ass jiggled with each bounce, sending shockwaves across her thickly preportioned thighs.

Knowing that Diana will be home very soon, you want to test something out.

"Amber, its pretty cold, wouldn't you say?"

Almost mindlessly, Amber gets up, and sits on your lap, her pussy just barely touching your dick. Her soft, juicy ass rests on your legs, crushing you. You reposition yourself, and you can feel her fat rear ripple like an ocean.

"Uh Amber, what are you doing?" I ask.

"Well you said you were cold, so I'm using my ass to keep you warm!" Amber said with a smile on her face.

You repeatedly flex your cock so it can feel around her outer pussy area. She hasn't shaven recently, so you can feel her bright red pubic hair interlock with yours.

Diana comes home soon after, so I get Amber off of my lap. When she gets up, I quickly give her ass a kiss so quickly that she didn't notice. The whiff of her private area makes my dick feel like it is ready to burst, but I hold off.

Diana notices that we are both naked, so she joins us.

We eat, and I make sure to say the word pizza as many times as I can without coming off as an insane person. Diana much more openly plays with her tits, which Amber tries not to stare at but is obviously arousing to her.

I can sense the sexual tension in the room, but it doesn’t seem awkward. The three of us have a normal conversation as Diana continuously kneads her tits.

I keep catching Amber trying to catch eyefuls of Diana playing with herself. I can almost hear Amber’s moist pussy dripping on the tiled kitchen floor. To think, before today, this scene would be a fantasy in my head. Now, I get to live it.

I see Amber biting her lower lip, and I take that as my queue to head back to my room. I leave the door slightly ajar so I can ease drop in.

I hear some russtling coming from the living room, so I decide to take a peak. I can't believe the godly scene that lay before my eyes: my own sister and her best friend were making out on the couch. Amber was sitting on Diana's lap, facing her. Their tits mushed together and became one mass of soft, fleshy meat. Diana was reached around Amber, feeling up her ass. I can just imagine Amber's pussy juices dripping down onto Diana's cunt, mixing with her own liquids. I see Amber reach down to where their crotches meet and bring her finger back to her face, sampling a taste of their own mixture. Diana, turned on by the sight, pulls Amber back in for another long, passionate kiss. They swap spit, sharing whatever Amber was tasting with Diana. They're tongues dance and seem to converse, as they push and pull into eachothers mouth. This scene only gives me future ideas of what I want to try with my gorgeous sister.

Amber gets up and leads Diana to what was once her room and locks the door.

Damn, I forgot to tell Amber that we don't lock doors in this household. It's getting late anyways. I go to bed, letting Amber spend the night with Diana. Maybe if I wake up early enough, I can get a glimpse of the aftermath.
