I m43 heard my mil 73 vibing herself outside her door.
Went downstairs early this morning to find my in-laws bedroom door shut. As I got closer I could hear a humming noise and soft moaning. It was my m.i.l.! Who knows where my f.i.l. was and frankly I could care less. I was wondering if she was masturbating to some dick pics I had sent a couple days ago (mentioned in a earlier post). I stay listening to her as she started panting and coming softly and quietly. I heard the humming stop. Ran upstairs to jerk off, after I got a couple rounds in I noticed right after my jerk fest my f.i.l. came and picked her up. I went back downstairs into their room to look for the toy she was obviously playing with. There is was in her sock drawer, a bit of cum residue still on it. A bit after I shot her a text saying "I was walking by your room and heard a humming noice. I found what was humming in your sock drawer. I turned it off for you". She responded "omg im so embarrassed but thank you". I reassured her it is totally natural and we all have needs and desires". A while after they got back home and she came up to the kitchen where my wife and I were. She gave me a cheeky little grin and blushed a bit. If this happens again I will shoot her a text and ask if she needs help.
