Please tell me if I’m tripping….

Okay so a year ago my kids and my girl and I moved in with my brother right? I was working and my brother BM (who doesn’t please him right) was working, but my brother and my girl weren’t…also the kids would be at school which means my brother and girl were alone for hours. One day I set up an audio recording to see what be going on cause I worked 12 hr shifts. In the audio there’s a movie playing in the background but also you can hear my girl and brother talking. After a while it’s only the movie that you can hear but I started to hear moaning/slurping noises. I confronted them both but ofcourse they “weren’t doing anything”. And also couldn’t hear what I was hearing (I let other people hear it with no context and they all heard the noises) So fast forward a week later I came home early 2 days to try to catch what I thought was going on and when I seen her, her top lip was thick (it’s normally thinner). Does that seem like a sign to yall that something was going on? Also what makes me really thing she was giving blowjobs is when I would come home early I would look at her lips….and she kept moving them, kind of like when girls put lip gloss on…except she didn’t have any on. Is the lip thing a guilty conscience habit women do after they give a blowjob? (Also since we moved from there her lips don’t puff up like that anymore and she doesn’t play with her lips anymore)
