One month sex life with my ex and her parents

[Ins]

Backstory: we were around 27 at that time and we had been living in 3 different countries, just looking for a better life and seizing the opportunities.
When all failed, we had to move back to our home town and didn't have anywhere to stay at first.
We had been together for less than 1 year at that time so sex life was at it's maximum.
Gf's family is conservative, working class with her mother being overly religious and her father just following along.
I had a really good relationship with him the entire time. Her mother on the other hand is a narcisist who just abused and traumatised her the whole life.(important later).
As it was a fast and great help, I moved in with them with the purpose of getting our own rented flat in the near future.
I want to add that her mother wasn't really fancying me.

Moving in with them was strange but a good solution to our problem. We had my ex's old room which shared a thin wall with the living room where they got used to sleeping since we moved together. Mind you their sofa/bed was directly next to the shared wall and even their sleeping position was with the pillow glued to that wall.

First 2 days we didn't have sex at all as we were exhausted with the whole situation.
As we all adapted we started to fell more relaxed with one another and the situation. On the 3rd or 4th day me we got horny while in bed watching a movie. Her dad was working nightshift that night so in the back of my mind only her insomniac (with papers) mother would be present. From one boob's squeeze to me licking her, then her jumping to suck me and then to us trying go be as quiet as possible with the strokes and her deafened moans was just a step.
I didn't last long as I was all worked up with everything till that point that I came in a few minutes. As she was used with longer sessions and more orgasms, for sure she didn't have enough.

Second night her father was home and we just went to sleep. One or 2 days later after this I had a shower first and was was waiting for her to finish hers so we could watch a movie. I remember she came into the room and started by removing her bath towel right away, smirking at me and waiting for my move. I smiled and just removed the blanket from me and she already was kissing me all horny and guiding my mouth to her boobs. I could tell right away how horny she was as she moaned heavily and was dripping wet (I realised I left her hanging days before). She didn't hesitate and just took my cock into her mouth while moaning as in "delicious". Couldn't wait longer so I just guided my dick right into her.
it all started nice, slow and quiet with me really teasing her with slow thrusts but in reality only trying to be quiet so I also had to limit how much I was entering her. Her first orgasm was right away as she didn't feel me for a long time and she was really worked up. She was kind of quiet but all this got us really excited as the thought of being caught/heard made us hornier.

* As days flew by we started getting more and more relaxed and also more daring with the sex.
First week or so we only did it late into the night but then we started doing it right away after we all went to our beds. She also started being more and more vocal and telling me to just fuck her already.
I realized something is up when she took control, asked her what's happenning. she answered by telling me that I must fuck her hard and positioned herself doggy.
As I knew her mother had just peed I started by teasing her with my dick on her clit and only entering her with the tip. she got fountain wet, broke loose from my hands grip, pushed herself hard against me to and took it all at once. she let out a hard and loud moan when I shushed her again and realized the movie had no sound deafening effect. That moan was impossible not to be heard by her awake mother and it got me hornier than ever. we were fucking pretty quietly me trying my hardest to not do slaps.

I realized that the best method was to hold her down really tight, and do deep hard thrusts. This made her cum after just few strokes and she burried her face in the pillow but still moaning too hard to not be heard. I was kind of feeling weird as it was now clear for all 3 what was happening in that exact moment and we were just getting started.
Couldn't hold myself though and had to go with harder and deeper strokes.

Fucking her faster made her again cum in seconds.
I switched to putting a pillow under her ass, taking her legs and putting them on my shoulders and slowly giving it to her with my hand on her neck this time.

After about one minute of slow fuck she saw she can't make me move faster and deeper as I didn't want to do slaps so wasn't giving it all so she was trying to move herself aswell and just begged me to fuck her harder. I told her I will but only if she's quiet with her orgasms. I saw her all tensed up and I knew she will start having orgasm after orgasm if I didn't cum soon and I wasn't even close.
I started going balls deep with a small smacking sound and after a few thrusts she just started having orgasm after orgasm. The sounds, the moaning, the idea we are being clearly heard and all the erotism made me cum soon after.

All was going well but we had a few rough work days and her father just being home at nights so we didn't do anything serious.
A few days after we got horny and had to have sex with her father on the other side of the wall.
I wasn't really feeling relaxed because of this but she almost kept her silence and even made me go slower when slaps could be heard.

At first I thought she realized we sre being too loud at night and we need to just chill, but it seems it was only due to her father being at home...

Next night her father wasn't at home we began being frisky right away. I realised suddenly that she is waaay to loud and just stopped. she thought I was joking but I reminded her that her mother is clearly awake and that her hard orgasming can for sure be heard. she responded by saying she cant hold it back even after trying and having a pillow on her face. She got mad for stoping and just put me on my back. I was so hard and horny at that point (as usually she wasn't taking controll at all), she was soaking wet at that point that I let her do her thing, didn't care anymore that the slapping sounds were loud as she was the one in control and just went with it, got up to licking and biting those nipples and holding her hair. She was riding me hard, moaning harder and faster, her nails in me and just orgasmed so hard and loud that she started crying while shaking almost as loud as when we were alone.
I had a moment of mental pause when she colapsed on me and just told her, not even whispering as it didn't matter anymore that it is way too loud and that her mother can hear us for sure and that we need to stop (in the back of my head I wanted her mother to hear that I am trying somehow to stop all this because I was starting to feel ashamed).
She got up, put my dick in her pussy, took it all in her, put her hands on my chest and started riding me again while responding (normal speaking volume) with "so what, she can hear how happy you are making her daughter feel because you fuck her so good". She was telling me this while going for my dick deep, moaning loud and gasping for air between words.
That second I was the horniest I've been in my life till now, I knew I had green light and just held her tight from her hips, smacked her ass, held her hair and just fucked her more loudly, checking every 10-20 seconds with her "if it's too loud" and she always responded with "no, just keep going".
I told her I was rock hard from hearing her moaning this loud, I held myself and fucked her really good after this. I just pushed the boundaries and increased the rhytm little by little and also going deeper and deeper and just asked her "is this too loud?" "can I go harder"?
As this was the first time we were fucking normally since moving she was having orgasm after orgasm and responded everytime with "it's not too loud" "keep going" and "yes go harder".
I just let myself free and fucked her almost like home, knowing exactly that even neighbours can hear us; I can only imagine that a thin wall didn't do anything.

For like 2-3 days her mother almost didn't talk with us or atleast not with me. She avoided eye contact and just avoided us.
I told my gf this, she observed as well, I told her it was too much and she just responded with "maybe she's just jealous haha, it will pass don't worry".

I caught her mother glancing more than a few times at my crotch area but I remember perfectly the next morning while she said a short and mad "good morning" , I was wearing shorts with northing underneath and was kinda fluffed up from just being woken up and caught her looking a few times that morning like trying to size me up (I'm like 4" flaccid).

As our schedule really only had us together while atleast her mother was home, I avoided as much as possible sex; more so after her mother seemed to be back to normal again after a couple of days. Saw her again cooking desserts, starting convos and what not so I was happy that she put that obvious night behind.

I really felt weird so I point blank refused sex or just had my girlfriend do blowjobs for like a week untill one night she wasn't having any.

I licked her pussy and had her orgasm twice and then she reassured me she will be quiet and to just fuck her already or she will "****" me.
I remember she was soaking wet and I put her reverse cowgirl. In my mind I wanted and let her know that she is now facing the wall where her mother is sleeping so to just be quiet. I didn't want to cum fast but she was getting so worked, tensed and loud again with her orgasms (like she didn't care) and was moaning louder with every stroke.
I came soon after.

Not even 20 seconds after this her mother goes to the toilet. Another sign she knew our every move.
She whispered goodnight when "in theory" we could have been sleeping and my gf just told her goodnight even if it was like 2 am.

As I sensed that her mother wanted to make us noticed, the exhibionist in me and also having the thought that she didn't fancy me and couldn't care less about me I started playing with my gf tits again. She looked at me in surprise because I only had like 1 minute since I came and I told her again that I get really horny when she is louder. I put her doggy after some oral play, held her down and teasing her with my tip, only getting like 1-2 inches in her and telling her to beg for my cock if she wants more. (pressing her buttons to work her up really good and I just wanted to see how far is she willing to go with this).
She obliged and imediatelly just told me "fuck me baby" then went on to saying just "put my whole dick into her". I teased her maybe a bit too hard as she kept getting louder and just scream begging me to just "fuck her harder and faster" and to "give it to her" already.

I asked her loudly what's the prize if I fuck her good and she told me I can do whatever I want to her.
(again I knew what buttons to press).
In that crazy madness, while going deep thrusting her I kept asking her louder and louder "if she likes how I fuck her" she answered while clenching and moaning hard "you fuck me so good" and even asked her loudly "if anyone ever fucked her like that". She just loudly said smth like "no baby, you fuck me the best from what I had".
She kept saying and repeating that I fuck her so good and before orgasms telling me "to continue like that because she's gonna cum" (usually she didn't announce her orgasms vocally).
In the heat of the moment I even asked her almost shouting "if she likes how big and hard I am" as I saw her aproaching an orgasm and she responded something along the lines of "you fuck me so good with that big dick"
(even though I know it's not big ~6.5" nbp and 6.9" bp) but I couldn't care less in those moments.

I took all these signs as green light, couldn't hold myself while she did this knowing her mother can hear aswell and just wanted to put a show that I told her to open her mouth and have her tongue out as I will cum.
I came so hard that it was one of the few times I couldn't control my grunting and moaning and just lost myself. She even kept saying "yes baby just cum". I was kind of frozen post cum but she ended the night saying it was the hottest orgasm she saw me having.

Fast forward a couple of days later her mother said we can't stay there anymore and to just find somewhere and move faster.

I know we crossed several lines but I was clearly more ashamed then my ex during those nights.
All the erotism, green lights, pushing from my ex for more and also the fact that her mother (who married young and had only 1 man in her life) didn't like me turned me on so much and also made me wanna show off and let her hear.
She was for sure sexually frustrated from her everyday life behaviour and for sure she didn't have in her entire life anything near of what she heard.
Pretty sure she didn't think this exists.
She is also kinda of jealous of her daughter (as every narcisistic parents) so I was pleased to help my ex show her mother what she's getting, how she's getting it and and how often.
I'm pretty sure my ex just wanted to show off and just "get revenge" with her because of her childhood.

I thought at first we are just being rude but later on thought about it some more and realized that their sleeping position could have been easily moved, the sofabed as well and all the bulge glances, relaxed clothing (everybody wore see through clothes at home, even my ex in front of her father) and mothing was said about this (not even 1 year after this).

Was everybody just onboard with this until one point? I would really like to think she got something out of it.
