I was in my room a couple of nights ago, making a naughty video of myself masturbating. It sounded really nasty to post it online, no faces, just lower body.
I got engrossed so much I did not hear my stepmom open the door, fresh sheets and pillowcases. It was a few seconds before I realized she was standing there in shock, I covered up, mortified.
She told me to relax, it was normal and everybody did it, then she left and came back with a box of tissues.
Leaving again, she looked back and said, "You are sure bigger than your Dad is." Then laughed and left the room.
