We got into bed together making out and a little light fooling around when I broke it to her of another friend online wanted to meet her I wasn't sure if she enjoyed the idea or was pissed but it must have killed the mood as she rolled off me and turned her back to me I apologized and kissed her shoulder to no response, I remember taking a while to fall asleep and she was there when I did but when I woke she wasn't there I got up and changed and went downstairs to find her sleeping on top of my friend naked he still had a condom on as if they fell asleep from fucking making breakfast must have woken them up as I could hear whispered talking from them and her giggling that update followed by having work done on our yard I was speaking to one of the builders early morning and she came out interrupting me asking me if id drop her off at her exs again that night I felt humiliation and redness across my face and saw the grin on hers I said yes and continued with the builder,
After driving her to exs on the way home I passed my online friend her kik details it hadn't taken the time for me to drive home before I had a msg from her the msg just saying "you're a fucking loser" slightly nervous she wanted to break up or was mad I messaged back asking everything was ok the message went straight to read but no response I got home spent a few hours playing games before I got a phone call from her the first thing I could hear was her giggling before her moaning I asked if we was ok she laughed again and called me a loser and hung up, the next thing I was getting ready for bed and I got a msg from my kik friend with a laughing emoji followed by a pic of her pussy she must have sent him it made me slightly happier knowing she at least wasn't pissed off enough not to think about it it got late to the point I was about to get ready for bed when I received a msg from her saying "pick me up loser" It was around midnight-ish I drove out and msgd her I was there it went to read about 10 mins later she came out I saw her ex giving her a kiss at the door and she got in the back of my car as I started up the car she told me to drop her off at the kik guys house it was over 10-15 min drive away it felt long in silence when we got there she asked me to wait until she was sure about it I did for about 10 mins until she came out again her hair was messed up that I noticed and he followed, they climbed in the back of the car both laughing I heard a slap of her ass as he let her climb in the back first as soon as they were in she barked out "home loser" he laughed and as I drove back they made out in the back continuously being broke up by her giggling I didn't catch when from focusing on driving but at a red light I looked back to notice his hand down the front of her jeans while the made out she noticed me looking and stuck her middle finger up at me I tuck it as a sign to keep looking forward,
We got home and walking to the house I could see his hands all over her ass as they waited for me to unlock the door I did and entered leaving it open for them to follow I walked to the stairs to go to bed when she stopped me saying "loser, I get the bedroom tonight" I couldn't help the smiling through the feeling of awkward and embarrassment as they went passed me she giggled as he said "thanks mate" and pushed passed me, I masturbated on the sofa hearing her moaning I don't think he even knew even he was the second person in my girlfriends pussy that night, I came as they continues another hour or so as I was drifting asleep until I was awoken to the refrigerator being opened I stuck my head over the couch to see her walking back to the stairs with 2 bottles of larger she saw me and stuck her finger up again and went back upstairs I could hear them going at it again as I tried and eventually got some sleep,

I was the first to wake up making myself some coffee to hearing her giggle as they came downstairs he sat on our couch as she came into the kitchen grabbed some fruit and gave me a hug from behind and she whispered to me if I minded giving him a lift back I agreed and she said she loved me , I wasn't looking forward to the awkwardness of driving him home but turned out to be amusing he was a nice guy we laughed and joked and spoke about tv shows every now and then he would compliment my girlfriend the only silent time we had was when he complimented how well she could take it in her ass and the thought crept back into my mind that I still had only tried it once,
Driving home I got a msg from my girlfriend saying "gone out wont be long bedroom may need cleaning up" I realised what she meant when getting home to see the bed covers tossed on the ground soaked covers and our draws in front of our mirror had everything knocked off them, there were items of clothing scattered across the bedroom, beer bottles were on the ground and in the progress of cleaning up the covers off the ground I found 3 used condoms not tied which solved why the sheets were soaked,

The builders were back and working in our yard and not sure if it was thinking about what my girlfriend was currently doing or cleaning up from what she did that had me feeling hot and kinky but i had told the builders at the start of their work they could help themselves to the kitchen and make themselves a hot drink when they needed knowing this as I stuck the dirty clothing into the washing machine I left out a item of clothing my girlfriends panties black laced and thrilly and very used from the looks on the inside I placed them in front of the washing machine as if they were accidently dropped and laid them out flat so who see them could get a good look to get to the kettle you had to pass by the washing machine and would have to step over the panties, I left them and continued cleaning upstairs a few minutes passed before one of them came in I waited until I heard the door close again before going downstairs the panties were still there and left untouched but the kettle was also cold and unused so I went back upstairs,

I finished cleaning and watched tv for a little until I noticed through window they were all drinking coffee and laughing and joking I went into the kitchen and my girlfriends panties were pushed to the side of the floor but were in a ball as if they had been scrunched up I hung around the door every now and then to hear if they were talking about it with no luck I tried 4-5 times but none of them said anything about her until 2 of them were left out of the four working outside 2 of them had left and they were cleaning up I was making food as my girlfriend said she would be arriving home soon as I passed the kitchen window one of the older workers broke their laughing between them to say "I bet shes a right fucking slut" I hoped it was my girlfriend they were talking about and gave me a instant erection thinking it was I went out seeing them cleared up and leaving to show them out and as soon as I left the house their talking and laughing stopped we spoke about how well the job was going on and said they will be back tomorrow and they left.
