My mom and my friend are being loud what do I say?

This is getting ridiculous. My mom and one of my good friends just started dating. They’ve really only been on 2 dates. Then on Monday I got home & could hear them and they were being loud moaning bed noises like the whole thing. I didn’t say anything because they didn’t know I had come home. But it’s happening right now I’ve been in my room studying for a mid term and working on a poli sci paper 📝 and I didn’t even know my buddy had come over. I looked outside and saw his car and now they are being super loud again!!! Moaning I can hear from my room, bed noises, everything!!! I’m not mad that they are seeing each other, but this is getting ridiculous? What do I say? do I say something to my mom or my friend. I’m also disappointed in my mom a little bit. She raised me not to sleep around! To be in a committed relationship, in love & then worry about bedroom business. They made out in my kitchen like 2 weeks ago and have been on 2 dates. 1 was to a restaurant that’s in a hotel and my mom said they were getting a room because she would be tired and too late to drive home. They prob did it then too! But they’ve been on 2 dates and go right to the bedroom? And just before you ask my mom is 39 my Buddy is 21
