Myself{36M}, GF{29F}, Her Brother{27M}, The full drunken experiment story[MFM]

So 5yrs ago on a Saturday, I got off work and i txted my GF an asked
she was doing. She mentioned that her brother was at the house an

asked to stay with us for the weekend. Since he was there I asked her if
she wanted to drink and to ask her brother too. They both said yeah.
So I told them I will stop at the store and pick up our usual an what he
likes to drink is Heineken, so I got him a 12pk(our usual is case of Dos
Equis, 5th of tequila, an 5th of fireball). Since my GF brother was there I
got a gallon of fireball instead instead of the 5th.I also got two 4pks of 16oz Heineken.

When I got home, the 3 of us did a shot an shotgun a beer. I jump in
the showered to clean off the work day. When I got out my GF an her

brother where already drinking. So I joined the in the dining room,
they where playing red/black drinking game. So I joined. They where
playing music an the mood was pretty chill. The house started to get a little hot. My GF went to the room to change her clothes. She came out in the boy shorts she has an one of my cut-off shirts I wear when I workout. I had to use the bathroom, my GF didn’t have a bra on so she said she was gonna put one on. When I came out of the bathroom, I
walked into the dining room an they weren’t in there. I then heard my GF in the laundry room. So I went in an I noticed my GF had the shirt she was wearing pulled up so she could put on her bra. That’s when I noticed her brother kinda seeking a peek at his sister. She didn’t notice
him, so he could see her boobs in full view. So I kinda made a loud noise. He then acted like he was going to the fridge to get a beer. I didn’t say anything.

We continued to play more drinking games, along with doing shots. My GF kept doing shots like it was going out of style. Everyone was pretty buzzed but we all knew what was going on. I went to the
bedroom to get my bud. When I walked out to go back to the dining room I heard her brother come out of the bathroom. I was walking in
front of him. I, then noticed my GF bending over the couch in her boy
shorts. Her ass looking so good. I still don’t know what made me do it,
but I pulled down her shorts little pass her ass an I spanked it. When I did I seen her brother stare her ass down for what seemed like a long time. She pulled them back up.

When she pulled them back up, she glared at me with a devious smile then sat back down next to me by the corner of the table. Her brother was sitting on the right side of her. I then knew she was getting little more buzzed then I was. So know how she gets when she gets like that. Usually, I don’t mind but this time her brother was there an I didn’t know how’d he react. My GF then asked if we wanted to do another shotgun. We said okay. But like times before when my GF is little more
then buzzed she spills it.

So we went into the bathroom again an she gets in the tub. We cheered our beers then shotgun them. Of course my GF spills some on her,
then pulls off her shirt in front of her brother. She didn’t care an he didn’t say anything either, so I didn’t say nothing either. I thought she was
gonna go put on another shirt. She did come back with a cut off shirt again but this time with no bra. Her brother noticed it an said where her

bra was. She said I thought you guys would like it better if I didn’t wear one. He was all “oh,” she looked at me an I said as long as your
comfortable. After couple more beers I looked towards my GF legs an noticed her legs where propped up on something. So I looked where

they where at. Her feet where on her brothers chair an she was using her toes to play with her brothers cock thru his shorts. He seemed

confused an didn’t know what to say.

I whispered in her ear n said WTF is she doing. She immediately stopped an said she was sorry. After her saying sorry couple more times I said I didn’t care but I didn’t want her brother think like WTF is she doing. I said as long as he don’t care or say anything she can do it.
She said only if I’m ok with it. I whispered in her ear again an said only if she’s only in her bra n thong. She looked at me an said really. I nodded yeah. She got up an went to the bathroom, she txted me an said
to make sure her brother was okay with it. So I told him that his sister was hot an would it be okay if she just wears her bra an thong. Since we where just in our shorts with no shirts. He looked at me like kinda shocked. He said if she wants he don’t care. so I txted her an said it was

cool.

She then txted back an said that we just have to be in our boxers since she was gonna be in her underwear an it isn’t fair. So I told him what she said, he agreed. So we just sat there in our boxers an waited for her to come back out. I got up to get us all a beer an pour us some shots. When I was pouring the shots I heard her brother say damn, I
looked an my GF walking into the dining room. Damn she looked sexy asf. When she sat down, she sorta sat with her legs facing her brother. We all took the shot, my GF asked for another one so I got up to pour her one. I looked at her brother an he kept looking down between her legs because she kept spreading them an closing them. When I gave her, her shot I noticed I had a txt.

So I checked it. It was from my GF an she asked if it was okay to tease him. I laughed a little, she looked at me an smiled. I smiled back. She told us cheers an to a get crazy night an crazier night ahead. She then took her shot. I could now see her teasing her brother a little more by
spreading her legs wider then before an sorta acted like she was rubbing herself. It wasn’t a constant teasing just a little here an there. But damn he kept having to adjust himself. My GF said to me couple times she was sorry that she was doing this. I said don’t worry about it.I asked if they wanted to do another shot, they both said yeah. so I got up an poured them.

We cheers again. This time I said whatever happens tonight stays in this house. They both said okay. we took the shot, an opened up us

another beer. When the last two 16oz Heineken cans. I told my GF an her brother can do them. So we went into the bathroom again. So before we got up I txted my GF an said for her to go first an that I’m going to tell her brother to go before me, an for him to slap her ass. She said only if its okay with me, that she really likes that an wants to know how it feels. I said this would determined his interest an gives me an idea of how to go about the night. So I said lets go to the bathroom, My GF got up an went first, I told her brother to go.

When he stood up I told him if he wants to slap or squeeze his sister’s ass he can. He got all excited. So when we where walking down the

hallway. I heard him slap it an squeeze it. My GF moaned an said that felt good. We where in the bathroom an my GF bent over and you could see her asshole, then stood up an got in the tub. So i said I’m going to count to three an for my GF to say the toast. So I did, an my GF said n looked at her brother an said he better do more then just slap/squeeze her ass. I said I agree. He didn’t know what to say. We went back in the dining room an got us more beers an asked if they wanted a shot again. So we did it, an her brother said he was gonna do
the cheers.

So he said an looked at his sister, if she wants more she’ll get more. I smiled an said that she better meant what she said an she smiled. we

continued to play music an then with my GF looking so fucking good
an with the thought of what was gonna happen later on. I started

rubbing my cock, my GF said couple times she’s sorry for being the
way she was again. She then asked if I wanted to go to the room real quick. I said okay, I told her brother we’ll be back real quick. He said okay. Soon as we walked in the room my GF said she was sorry an wanted to make me happy. She pulled down my boxers and started sucking my cock.

My GF was sucking my cock for couple minutes. Once we entered the room an her taking off my boxers I was already taking off her bra an thong. So now she was completely naked on her knees. By this time I had her bent over on the bed in doggy an I was fucking the shit out of her an I had her moaning loudly. We totally forgot to close the door, an I heard my GF gasp, so I looked towards the bedroom door an I seen

her brother rubbing his cock an he said to us that he could hear his sister an that it made him more hornier so he came to see. He said he

definitely liked seeing his sister bent over an being fucked. My GF looked back at me an with me still fucking her the look she gave me an

I nodded in agreement. She then turn back towards her brother an put out her hand. When she did that her brother with still his cock in his

hand he walked over to us.

As soon as he was within arms length she grabbed her brother by the boxers and pulled them down then she started to rub his cock and
then I told her it was okay, when she heard those words she started to
lick the head, when she was doing that I started to fuck her harder. She moaned and screamed along with sucking her brothers cock. She then started to jack him off while she was sucking on his nuts. I could feel
her pussy get even more wetter. After a little bit I looked at her brother an asked him if he ever thought about fucking his sister. I said I

honestly wanted the truth from him. He looked at me an looked at his sister an he said he always thought about an liked to hear her moaning when she was getting fucked.

He nodded yes he wanted to fuck his sister, so I turned her around an put her on her back. I could see how wet she was an her pussy was all
glistening an I slid two fingers inside her an she was so fucking wet an
warm. My GF told her brother that he had to put on a condom because
she wasn’t on BC. He did an I watched him climb on the bed an get on
top of his sister. Then I watch her pull him closer an move her hand between her legs. She guided his cock to her open wet an juicy pussy
then she pulled her hand out.

With one thrust he slid his cock all the way inside her. I heard her gasped an then moan. He started fucking her an her moans where so
good to hear an I climbed on the bed on I started rubbing my cock on her face an putting it in her mouth an I asked if she was enjoying it. She
said she fucking loved having her brother inside her an me putting my cock in her mouth. By just watching her get fucked by her brother an it

turning me on so much I came all over my GF’s face.

My GF swallowed the rest of what was dripping out of my cock. I then told my GF it was her brother’s turn to cum inside his sister. She said she really wants him too. So I told him to put his sister’s ankles on
his shoulders an fuck her as hard as he can an that I wanted to her hear her screaming an that I want to hear her saying that she is cumming too. He had her legs on his shoulders for about 30secs before I heard my GF saying she’s cumming. I think that’s what made her brother go over the edge, because as soon as she said she was he
moaned that he was cumming too. He fell on top of his sister then rolled off an pulled off the condom. it was completely full of his cum.

After he said to his sister thank you so much. She nodded okay an said that it definitely ain’t the last time they are gonna fuck. He then

got up an an went to the room where he was sleeping. My GF an me got up an went to go shower, then after we laid back down naked and

fell asleep.

Every now an then when he comes to stay with us, we usually get drunk an end up all fucking. Right now we even got to the point where
we DP my wife. She absolutely loves being stuffed by the both of us.
(My GF became my wife)
