This has only just happen recently after lockdown. During the first lock downs I was still working and had lots of extra work due to this pandemic my partner abbie was made redundant so I was working for the two of us. This meant she had a lot of time on her own as she had to sheild due to a heart condition. When it came to the last lock down I was laid off work so it meant I was home all the time and it seemed me and abbie had grown apart we was still living together and sex was non existent during our relationship I did ask for a threesome or to watch but she was always dead against it and would stop sex if I brought it up. Then one day while having a beer together both tipsy she brought up that she actually has an obsession with a famous guy and been following him on social media and as we been living in separate rooms she had been playing with herself over him. The night ended with us having a mutual play but in the morning she said that would never happen again. When lockdown ended we both found work again I went back to long hours and she found a 9 till 5 job and when we had time we chatted about work as we still friends and she mentioned that there was a young guy that looked like the guy she was obsessed with but he was only 19 (we are in our 40s). A few weeks went past doing our own things nothing out the ordinary until one night I came home slightly earlier to see a car come out our drive (we share a long drive) so I thought it be one of the neighbours friends as I saw 2 young lads in it when I got in abbie was just in her dressing gown and was shocked to see me. I went to grab a beer and noticed there was a few missing so I asked her if them lads were here and she denied it until I walked into the lounge and found some boxers that wasn't mine. She then admitted she had the young lad over as they been flirting at work and his mate had just come to pick him up. I was hurt and pissed off as she is only staying till she can save for her own place and we agreed we don't bring anyone home. But I was also very turned on we both went to our rooms where I had 2 wanks in the space of 30 minutes. The next morning she got up for her run and I came down for a cup of tea and I saw her phone open on the side. I know I shouldn't but I read some messages some where between other guys she was talking to nothing exciting then 1 between her best friend who was egging her on and the other was between this young guy. Her.. he found out last night you left your boxers and drank his beer plus we have and agreement that we don't have sex with anyone here.. Him .. his loss should of kept you happy. Him.. still on for after work tonight I need it again. Her. No we shouldn't of done it your to young you caught me off guard and he be home from work. Him.. you loved it its the biggest you have had and the biggest cum you had. What time he finish. Her. About 9pm and we should of used protection I am not on anything and yes to both but please stop I have your cum still leaking out xx Him.. I be round after work xx Her.. ok bring condoms and your own beer. After reading that I ran back to my room and had another quick wank. She came back from her run had a shower and we briefly chatted and she asked what time was I finishing work I told her it would be a late one as its Friday and we have to get stuff done. The truth is I finish at 5 on a Friday as my boss and his wife take over and I was off Saturday. The whole day I was think of a plan to catch them or watch the and not to spook them before they started. I left work at 5pm for my 20 min journey and I realised I would need to give them more time so I stopped for some beer at a shop then the local for a pint or 2 and about 7 I left my car at the pub so I would make a noise on the gravel drive and walked the 10 minutes home. I managed to sneak to the back door to find it unlocked which was a bonus and I snuck into the lounge thinking they be there and nothing then I heard her soft moans from upstairs I tried to climb the stairs without making a noise but it's an old house so I made a dash and I got to her room door to see this young lad on top giving her his all she look up and saw me but she was going through and orgasim and just smiled he saw me and just carried on and said he was about to cum and she told him to pull out but just as he was she hit another orgasim and pull him back in. It took a couple of seconds for her to come round and she kicked him off l. I told her not to panic and carry on and she told me to go away and wait downstairs so off I went I grabbed 1 of his beers and sat on the sofa. After about 20 minutes of me listening her moaning but also complaining he can't get it up they both came downstairs and both grabbed a drink abbie then said he was going to stay the night now and was sorry but she need it, I told her she broke the rules again next time she be out with that the young lad looked up from his phone and said he mate was picking him up as he was going to a party abbie asked if she could go and he said no you be to old and with that he got up and left. Abbie was left shocked and in tears and I had the biggest hardon ever she got up and said she need to wash his cum out of her cause she felt used and just out of cheek I asked if I could eat it out she said no at first then she broke down and cried we had a cuddle where I the slipped a finger into her and her pussy was soaking she moaned and I went down on her on the sofa, after about 5 minutes of me licking we both got up and went to her bed. I wish I could say I last for ages and gave her a good pounding. But no as soon as I slimy cock into her and felt the heat wetness and that her pussy had been stretch I cum instantly. I laid on top and seen the disappointing look on her face so I carried on my softening cock slipping in and out until I started to get hard again the second time I lasted about 45 sweaty minutes and I asked her do you want more cum in you and she said yes she wants a baby as she not had one . After we laid there and chatted I asked if she wanted mine or his she said it didn't matter she just wants a donor. We both woke up the next day she was in a bad mood and I went to work. That was 4 weeks ago she got fired from her job but I don't know the real reason she has missed her period and still not spoken to the young lad he has ghosted her and we both back in separate rooms and don't talk about anything sexual..
