New siblings

You are excited and nervous about the new siblings, you know that your mom only wants them so she can fuck them but to you it's more siblings that will share more with your Girlfriend and her sister than you do. When you went down for breakfast the twins were both below the table sucking on your mom and not being quiet about it either.

You must have had a look on your face when you sat down and started eating because your mom says "Oh they are sharing a meal today" then resumes eating her own food . The day passes quickly though as everyone is excited about the two new residents.

They don't arrive until after lunch almost dinner time, when they showed up everyone was dressed and actually decent the clothes were actually covering everything. Your mom didn't try to hide the bulge in her pants though.

They don't knock on the door just opening it and there was a squeal of happiness and a shout of "MOMMY" and she runs forward giving Ellie a hug. You weren't fully prepared for the weirdness of two girls of the same age hugging as one calls the other mommy. But she does look incredibly happy as they hug each other.

The other girl isn't as bubbly as the first one that entered, she does seem kind if irritated and looking at her you recognize her from the girl in the photo this one is Carol's daughter. When she speaks though you can tell she is just nervous "Hi..." with a small wave at everyone. After saying that though her confidence seems to improve as her posture changes, her new posture really shows the hips she got from your mom. Her eyes then lock to Ellie and their hug when you look at them you see they have a full on make out session going on now their hands hiking up their skirts revealing neither of them are wearing panties as they use their fingers on each other.

Your mom is enjoying the show she watches them and her erection is very obvious in her pants. She doesn't stop them though and is about to reach out to join in when Carol claps her hands together producing a loud sound that shocks them out of their make out session. "There is plenty enough time for that later. Lets at least get introductions out of the way"

As if suddenly having a revelation the girl hugging Ellie speaks up "Oh right, my name is Stacy" and tries to go back to making out with Ellie but your mom easily pulls her off and carries her to the couch and placing her on her lap. With the way Stacy is moving she is definitely grinding on your mom's cock. When you weren't looking you spot the other girl give Carol a hug from the corner of your eye, it looked to be a rather forceful hug and she squeezes her tightly.

They separate when you turn back to look at them and before you can say anything Ellie pulls you down and forces you to sit in front of her with her legs on your shoulders, as if showing the new girls just where you belong.

Carol sits on the arm the couch and the last girl who hasn't introduced herself yet is standing close to you her crotch is directly in front of your face and the legs of Ellie prevent you from looking away. But it's not like you are being **** to watch her expose herself because she is wearing a skirt. She stops just close enough that prevents you from looking up her skirt, which is actually quite close because her feet are on both sides of your knees as you are sitting cross legged. Well within the uncomfortable zone for the face to crotch distance, when you look up you almost think she is looking at you with a strange smile on her face.

She then introduces herself "My name is Amanda but I wont mind if you want to shorten that or something."

Your mom speaks up "Well Amanda Your room will be with John. Little Stacy here is going to be staying in my room" the very same 'little Stacy' is no longer trying to hide the fact that she is grinding her hips on your mom's cock as she lets out soft moans. Your mom then says "Well since introductions are done we can show them their rooms and then we can have dinner" she gets up carrying Stacy who spun around and wraps her legs around your mom holding herself up as your mom makes her way upstairs and the twins try to follow her but your mom stops them "Now now it's only fair she gets her first time alone like you two did"

The twins nod their heads and head downstairs leaving you and Amanda alone in the living room. She states "She's going to get pounded real good"

"Yup" you say easily when you look back to her she is still standing uncomfortable close to you. Now that no one else is in the room you realize that earlier she wasn't looking at you, she was looking at Ellie's exposed pussy because her legs were split open to accommodate your head.

When you move to stand up she backs off and moves to the two bags still by the door. Your mom didn't even make an effort to disguise that she just wanted to fuck Stacy when she said she was going to show them the rooms.

Amanda tells you to pick up Stacy's bag and she follows you upstairs. Your mom left her door open so you enter and you see her deepthroating your mom's cock when she sees you she pulls off it. Your mom says to her still not noticing you "You're good at this"

She smiles at your mom and says "Of course you made me practice a lot" you quietly place the bag on the floor and leave the room and you close the door on the way out. You try to process what you just heard but it's only a few steps to your room and you lead Amanda in the room.

You swear in your head you forgot to clean up after moving Ellie's stuff. So drawers are open and you didn't do your laundry so there quite a large pile of clothes in your basket. There are a pair of dirty pants on the bed you forgot to put away while looking for Ellie's clothes. You pull the pants off your bed and to your confusion there is something in the back pocket, you pull it out and put the pants into the laundry. It's a small unlabeled bottle with a small note attached to it, you don't get a chance to read it but you do remember Jen sneaking something into your pocket the last time you were at the lab.

You watch her unpack, it's all just a few changes of clothes a laptop and a phone. she places her laptop on the desk and after everything is away your door open and the twins enter the room. They shout "Happy Birthday" and they each produce a single wrapped gift for her.

Amanda looks incredibly happy at the surprise birthday party she takes the gifts and sits down giving them both kisses. Incredibly hot kisses with tongue and everything leaving the twins breathing heavy.

Carol speaks up "We noticed you weren't all that interested in your mom so we decided to give you some gifts" You guess that's true Amanda really didn't seem interested in your mom at all but was interested in her other mom and her aunt. "Well we will leave you to get settled in. I don't think there is going to be dinner tonight, so if you are hungry just have John make you something, he is a decent cook"

They leave the room and she turns to you and opens the small present, you recognize the small square packaging. It is the reusable condom from the lab, you remember what Jen told you about it that the material allowed for it to accept large quantities of cum.

When Amanda looks at it she has a confused look on her face so she asks you "What even is this?" and when you explain to her about the functions of it she nods "That sounds useful" and sets it into her drawer. She then opens the next one and its a large assortment of clothes, understandably no underwear but plenty of skirts pants and shirts which she puts away into drawers. You think about one good thing about them being the same age is that they are around the same size allowing them to change clothes easily. There is one item she pulls out though its a pair of bright pink ear muffs with cat ears on them. Your palm meets your face as you realize this was the secret of how people get sleep with your mom in the house.

Amanda looks at you when you do this so you explain "I just realized that I could just get some earmuffs so I don't have to listen to them going at it all night" while you point a thumb at the wall to your mom's room.

She laughs at you and she reaches into a drawer and pulls out her own pair of simple black earmuffs she passes you the pink ones "Well you can use these for now I already got a pair I like more." she then explains "All my sisters are loud so I asked for a pair before I left" with how horny Stacy was being earlier you can understand what she's saying. This does bring up what you heard in your mom's room but before you can get some clarification on that she asks "So did you get me a present?" she grins at you probably knowing you didn't you scramble your mind trying to think of something anything that you could give her.

You remember the small bottle Jen gave you. You pull out the bottle and read the note attached to it 'This is product of your test the other day enjoy ;)' Yes Jen wrote a winking face on the note. You feel a bit weird giving a girl an enhancement for a person with a dick but putting the bottle back would give away that you didn't actually get her a gift. "Yeah I got you this" you place the unlabeled bottle in her hand

She looks unimpressed "Oh sweet I always wanted a bottle of unknow fluid" The sarcasm is strong with this one. You cough a bit and explain what exactly it is mainly just saying what your mom told you last night. She now actually look excited about this gift "Oh that sounds like a ton of fun how do I apply it?" she asks.

She starts undressing herself her top is off and just like everyone else she doesn't wear a bra. Her nipples are much smaller that Ellie but they are just as pointy. When her skirt is off she quickly bends down she shoves her ass in your face as she removes her panties, you note that under her panties she has a tight wrap around her. You realize that Amanda has a cock she just kept it hidden by a tight wrap around her waist. She lets out a very relieved sigh as you see she really inherited a lot from your mom as she is just as big as your mom, she will probably be even bigger than your mom when she matures.

She looks at you "So you going to help me use this stuff or should I just ask my mom for help" you don't think she's talking about your mom when she says that.

So you speak up as a deterrent "Uhh.. I don't think that'd be the best idea, you aren't supposed to cum until morning for the best effect" You explain to her how to apply it. Then she lays back on the bed and opens the bottle. Unlike the one your mom used it has an incredibly strong scent, smelling every bit like the medicine it is. After she applies it she massages her large nuts "Wow that is a strange feeling, but I spent 18 years without cuming once so I think I can survive one more night" Wait not once in her life? Considering what you heard in your mom's room she definitely should have at least jacked off once right?

You decide to ask her about it "Wait you didn't like have to relieve yourself?"

You don't understand the look the she has on her face "Oh I got horny and the other girls masturbated lots, without a physical body there wasn't a NEED to relieve myself. However that wasn't the reason I never did, it's my condition it has the affect of making my cum addictive if someone ends up with my cum inside of them they will accept my orders more and more" Her cock seems to get harder and harder as she speaks "Oh I so wanted to make some of my sisters my little pets, but they said in no uncertain terms that I was not to cum at all in the simulation" She smiles a bit "Then when we were out they put me in a different room by myself and didn't let me walk around without an escort"

"Why did they say you couldn't cum at all in the simulation?" you couldn't help but ask

She laughs "Because they don't have a way to monitor what is actually going on in the simulation, but they can monitor the minds of the people inside the simulation so they just banned me from ever releasing my cum when the time came to learn about that part of anatomy"

"Why didn't they just remove that from the simulation then?"

"Because then what would we really learn? If the world was censored you wouldn't care about the things happening to others. So instead of just removing the effect of my cum they made me aware of what my cum does and told me there would be punishments"

She still continues to massage her nuts "Wow this feeling really doesn't go away at all" She looks at you and sits up "Well better get undressed and get your earmuffs on mom's about to start" she tosses you the pink earmuffs with cat ears on them and she pulls her own over her ears.

"How do you know that?" You've no idea how she can tell.

"Because they get a brain scan of our parents and put them in the simulation with us to help raise us, but they don't have the ability to change so they get very repetitive after about 15 years or so" then proving her points you hear the scream of Stacy losing her virginity you quickly put on the pink earmuffs and it works well at blocking the sounds

She reaches out and pull on your clothes and mouths the word 'off' at you. You sigh but you can't hear it and pull of your clothes. Once you're in your underwear she is still waiting for you to finish though obviously expecting you to be completely naked like her. When you don't move to remove your underwear she just reaches and yanks them down for you

Then she pulls you into the bed and rolls you around so she is hugging you from behind squeezing her breasts against you and you can feel her cock on your back. Without the constant sounds from next door you do manage to easily go to sleep.
