[Non-Fiction] My Sister Meets My Mistress

[Legs4Days]

This is a continuation of my first story which you can read here:
http://www.getdare.com/bbs/showthread.php?t=265743 .You don't exactly have to it just talks about the first time me and my adopted sister did anything sexual together. You should give it a read if you have time, if not then whatever.
This story takes place a little over a year after the last one nothing much had happen between me and my sis since maybe the occasional kiss for fun but nothing else really and involves three main people me(Sarah), my sister Jess and my gf/dom of 2 years at the time Alex.
The story will be colored as such:
The story will be in purple
Jess's text will be red
Mine will me be blue
And Alex's will be in green!
A bit about us:
Jess: 18, Medium height, shoulder length dark red hair, half Mexican half white so she was dark but just looked like she just had a nice tan, C-cup, green eyes, very quite but had the cutest laugh and has come out as Bi since the last story (shocking right?)

Me: 19, a bit taller than Jess but not by much, Pixie cut neon blue hair, the whitest girl this planet has ever seen, B-Cup, Blue eyes, pretty loud and also Bi

Alex: 20, two inches taller then me and Jess, short dark green hair, white with a slight tan from sports, green eyes that can just cut you down if she looks at you just right, quite person unless she is telling people what to do, not shy she is just always thinking it seems like.Lesbian.
Now its time for the fun stuff here is the story!

It was the Tues of spring break and my sister and I were both at home and this was around noon. Mom was at work like usual when I heard a knock at my door.

"What do you want?" I yell through the door from my bed.Jess peaks her head in. " Hey could i talk to you for a coupe seconds?"
"Sure"
She sits on the floor. "How are you and Alex doing? "
"Fine we are hanging out on Thur. Why?" I ask sitting up from the bed.
"Just curious I think you guys are cute together so making sure you guy are still staying strong"
"Yeah like i said we are doing fine."
"Cool"
Then we chatted a bit about school, stuff in our lives, people we hate then she ask this.
"So are you into bondage?" shes stood up and started walking around the room.
I choke on some water i was drinking. "wha.*cough * Like whips and chains? Sure I guess it seems fun?"
"Does Alex?" she ask as she stares at me
"I don't know for sure I think she has mentioned it in passing." (I had already been her sub for over a year i was trying to cover)
She steps towards me a bit. "So like being tied up and stuff? You and Alex both like that?"
"I can't say for sure if she does. I said it could seem fun."I lean back as she gets closer.
"So Alex has never tied you down and had fun with you?"She leans onto me pushing me with her hand till i lay on my back. "and you only think you like the idea of bondage? The thought of being controlled doesn't turn you on? "
I get kind of turned on by her presences but also scared "N. No wh." my words are cut short as she pushes against my pussy through my shorts.
"Are you sure? Then whats this about?" She opens her phone and shows me a picture Alex took of me from a few weeks back.
It was me, naked, tied spread eagle to a bed, blindfolded and with a vibe in my kitten. Alex had taken it and sent it to me as a "Helper" if i needed something to motivate my sexy time alone. But how did Jess have it?
"Saw this a couple days ago on the ride home when you let me use your phone cause mine died. Look at you! You seem to be having fun. So i sent it to myself."
"What why would you? "
"1. Being honest, because it pretty hot seeing you like that and it helps for my "alone time" " She pushes more against my body and kisses me. "and 2. because I want to try it."

Idk how much demand there is for this but yolo.

Part 2
"what do you mean?" I say in a haze of confusion.
"I want to try it! I want that to be me! I want to be helpless and be getting that kind of attention. You seem to enjoy it..But also. I want to try the other side. I want to tie you or someone down and see what i can do to them and what they will beg me to do to them." She says with an evil tone and almost evil smile. "Please!"
"I don't. Why don't you have a guy friend from school do it or something? Im sure any of them would love to. "
"First of all I don't want that kind of reputation around school and secondly I want someone who I can trust and who knows what they are doing. Please Sahara! Ill do anything!"
I think for a couple seconds. I guess it would be scary asking a stranger. "Fine Ill ask Alex about it it but no promises okay?"
"Yes thank you!"
"Now can you get off me?"
"Well actually." I hadnt noticed but she had undone my shorts and had slipped her hand down the front of them. "I still owe you one after Jenga" Her hand slips under my panties and she rubs my wet pussy.
I bite my lip but resist. I wasnt supposed to orgasm without Alex's permission. "Sorry another time please Jess. I need to text Alex"
"Fineeee. Your loss though." She pulls her hand out quickly making me gasp. She licks her fingers "Can't wait" she says with a wink then leaves.

I lay on my bed and try to regain composure before flipping over and texting Alex. She had known about the Jenga incident.I told her once we got back together. She thought it was funny and said she was proud of me for it. I explained what had happened and told her Jess wanted try BDSM. After a couple minutes she replied:

Together? Like all 3 of us?
Yeah I think so!
How do you feel about it?

I didnt exactly know how to respond. She was my sister after all. But she did seem eager. Eventually the devil killed the angel on my shoulder.
I think it could be fun if you're up to it.
After a few mins... Okay whats her number
XXX-XXX-XXXX So are you in?
We will see but i think it could be fun >: D
That was it for that day and I didnt hear much from Alex till Wed night, She put all three of us into one group chat,
Okay pets Ill pick you both up tomorrow at noon.Just bring a change of clothes and telly your mom ill have you back by Sat morning
Yes mistress
(Did Jess just?) "Yes mistress" is all i said in the chat.
I texted Alex separately
Did Jess become your slave?
See you at noon S
I didn't bother asking Jess. Part of me wanted to keep it a mystery anyways. That night I laid in bed thinking about what they must of talked about. I woke up at 9. Showered and bumped into Jess heading down the stairs.
"Excited for today?" I asked shyly
"More then you know!" she said as we both went down stairs.
We just watched TV and didn't say much and noon sneaked up on us. We both got text at the same time and wemt outside with out backpacks.
"Both of you in the back!" Alex yelled from the window of her car.
"Yes mam" we both said and jumped in the back.
I noticed Alex was wearing the same outfit that she was the day i met her. Green and black corset and jeans with holes ripped in them. She adjusted her mirror to see us.
"Okay girls tops off. Now!"
I hesitated but Jess seemed to start to take her shirt off.
"I'm kidding! how are you guys?"
We all chatted as Alex drove us to her place. Nothing to serious just chatting about our lives and spring break. We get to Alex's place in about 20 mins. Despite her look Alex came from a more wealthy family and she was the only kid. She told us on the ride that the parents were gone for the week and that we would have the place to ourselves. .

We walk inside and drop our stuff/ take off our shoes and Alex goes to the kitchen.
"Want any drinks?"
"No Im good"
"You sure? You might need fluids."
I swallow nervously
"I'll take a water. "
"Same"
After about a minute she comes out with 4 cups of water. Me and Jess take one each and Alex drinks from a third.
"Whats the fourth for?" Jess ask
"Funny you ask. Okay ladies now get down into your undies. Lets see those bodies. "

Part 6

We continue our walk to the movie theater. I talked to Jess a making sure she was okay and I told her she didn't have to keep doing this stuff Alex would understand. She insisted she was fine and that she was just glad Alex was there. Honestly. I was too. I don't know what I would of done to that guy. I had only been in one fight and that was with a girl my size. Not a guy who was half a foot taller and had 100lbs on me easy. I would of tried to stop him but. Im glad Alex was there is all. I asked Jess again and she insisted and turned on my vibe to a low setting which i took as okay end of conversation. As we are about to walk in Alex hold up a coin.

"Jess call it" as she flicked it into the air

"Tails never fails."

Catches the coin. "Well this time it did. Sorry kid."

We walk in and Alex buys all of our tickets to some horror movie (The last exorcism maybe? Idk I dint pay much attention to it ). We get our popcorn and drinks. I remember Alex ordering hers with extra ice and when she did Jess gave me a worried look. I laughed because Alex did that with all her drinks cause she likes to chew on ice not as a kink thing.

So we walk into the theater and it is EMPTY. The only other people is some young couple in the very front who are to lost in each other to notice us. Young love is so cute. Instead of sitting in the middle of the row in there Alex has us sit in the very top right corner the farthest seats from the door .

Nothing happens until about 5 mins into the movie. We were sitting. Alex in the corner, then Jess then me. Alex leans into both of us and whispers.

"Both of you take off you panties and and put them inside your pussies. "

At first neither of us moved probably because both of us were trying to process what she said. But she snapped her fingers and gave us a look that meant business. Thats all it took for both of us to begin to remove our undies. Jess got hers off first probably because she had a g-string on and I was wearing full boyshorts. So we both get them off while Alex pretends to watch the movie. She clears her throat and we both spread our legs a bt and begin to insert the undies.

With the vibe already in there there was not a lot of room for the underwear so i had to move the vibe around which felt sooooo good to be able to touch myself I almost got lost in it when i realized Jess had already put hers away. I managed to do the same and we both closed our legs and went back to watching the movie. Then I feel a slight buzzing coming from between my legs. its very middle of the road . I guess 3. But it is enough to make me bite my lip and cross my legs as Jess just glares at me.

"This is for that cheap shot in the basket ball game" she whispers in my ear as the vibe buzzes more. "I hope those panties get nice and soaked by this. "

The buzzing became more intense and with the panties in it just pushed the vibe even more into me. I tried to not focus on it but I couldn't. All my mind could thin of was how amazing it felt in between my legs. My eyes closed, my head went back, one hand went to my breast as the other grabbed my hair I bit my lip to try to silence the moans. My body begins to rock in the chair just wanting to feel more pleasure. The rush keeps building and building. I can't take it anymore. I unbite my lip and as I'm about to moan Jess covers my mouth with her hand and with the other she pushes on my crotch area. I don't know if it was her pushing or if that was a coincidence but at that moment I orgasm. i moan quietly into Jess's hand and I melt into my seat breathing deeply. I look over and Jess is smiling and Alex is looking at me while drinking her soft drink.

"Now that thats done. " she says in a tone almost to loud for a theater. " S get naked and eat out your sister"

Both of our jaws fell open and both of us tried to make words.

"Well do it before the movie ends! Hurry! Jess take out your vibe and panties "

After a couple seconds my horny brain took over. I wanted to do this. Maybe not in this spot or naked but I wanted to eat her out again. I had had so many fantasies about it over the past couple months. Before the angel on my shoulder could say shit my dress was off and I was undoing my bra. I got it off and covered up for some reason. My nipples were hard either from the cold theater or from the recent orgasm. Jess and Alex were watching me strip the whole time then Jess pulled the items from her slit.

I got on my knees in the isle. Luckily the floors were more clean then I had thought apart from one small sticky part my leg brushed up against. I crawled in between Jess's legs as she opened them slightly pretending not to look at me. I poked my finger in and rubbed her clit which she moaned at then looked down at me. I winked then stuck out my tongue before moving my head in.

I couldn't see much, the theater was dark itself and under the dress there was even less light. But i could make out her dimly lit slit. She still had no hair down there which made me lick my lips over also from seeing how excited she was. I gave her one kiss on her lips and then stuck my tongue in right away. She tasted so good. I could of stayed there all day just tasting her juices and smelling her aroma. But I knew we had a time frame so I got to work with my tongue as fast as I could quickly darting my tongue around trying to remember which spots got to her the most. It only took a couple mins to find 3 or 4 that I could feel her body really react to and a min or so later i thought i felt something tap my inner thigh and I panicked and pulled my head out which made Jess gasp.

"Sorry just need to borrow these. " Alex said and before I could ask she reached in between my legs and pulled out my panties i moaned and gasped quietly. She kissed me and licked her lips. "Thanks!" then she went back up

I went back at it licking her more and more. I thought I heard her moan but it sounded muffled. I kept licking making sure to rub my tongue piercing against her clit. I loss track of time I was just having so much fun. The risk of getting caught eating out my sister naked in a theater just turned me on more and made me pick up the pace. At one point a jump scare happened in the movie which made me stick my tongue in and out quickly and Jess gasp either from me or the scare itself. Either way it was funny. So after a few more mins, Jess began to rock her body and moan more and more and after a couple more seconds she pushed my head in deeper and with one final clit lick i felt a rush of liquid on my face and her body go lax.
