What to do when you heard your mom giving her bf head

So this morning around 11am after i got breakfast i went upstairs to my room and could hear my mom giving her boyfriend oral sex. I could hear because we have thin walls and i could hear her choking and a very loud sucking noise. It was absolutely disgusting and the fact that they are doing this in broad daylight knowing i'm in the house just one thin door away from them. I am absolutely disgusted and just want to throw up because of how loud it was. What should i do in this scenario?
