Dad has recently gotten himself a much younger girlfriend whom he has moved in last month. My bedroom and their bedroom are wall to wall. The fact that they fuck doesn’t make me uncomfortable - so happy for them, but they do it on max volume. No joke. Every night at 11 and in the morning at 6 on the clock. These walls are paper thin apparently.
They absolutely know they can be heard. You just have to tell him that it isn’t cool and that you don’t want to hear it.
