My brother is screwing our mom

Another time around here, since I had the opportunity to see them again. This time was because I had missed work to get my tooth pulled and from there I got a fever. I stayed in bed all night resting that way 6/7 am I was waking up because my old man usually leaves and I have to close the door sometimes. So when I get up to go to the bathroom, I notice my brother wasn't in his bed and it seemed weird, I thought he had gone to the bathroom and went too, but when I got there I see the light is off, already between you and me I stayed thinking where the hell did he go, since he never leaves and when I'm looking for him barefoot, I get to my parents' room and there I hear my mom talking to someone. I thought she was on the phone and didn't want to give a damn, but after listening to my brother's voice I stay careful and pay attention because already know the forros and when I get closer, I listen better. My brother was saying (I don't remember the words well); Dale ma, he's sleeping and won't wake up, you just suck for a bit and then I'll leave you alone. My mom was saying no, that maybe I'd wake up and find out, that made me calm down but when my brother got more insistent and broke eggs, she didn't take long to give in and well, there they started doing what they always do. First my mom gave him a blow job/ sucked his cock right there and it lasted for a bit until my brother asked her to make him cum. Already then I couldn't take it anymore and went back to bed, now already knowing that every morning when my old man leaves for work these two must give each other good head. They were there almost till 9 am or so and after that I could hear my mom in the kitchen preparing breakfast, knowing that my little brother had eaten her out again and gave him his cum as a breakfast treat. (Any topic they talk about privately.)
