I recently had a day off from work. My wife was at work, and my mother-in-law was in and out of the house. She was moving into the spare room for a couple of weeks. The house was quiet, so I took a shower around 9:00 a.m. I ran across from the bathroom to our room naked. I laid on the bed and rubbed myself with hand cream. As I stroked myself, I heard the door open a crack. I peeked over at the door and saw my mother-in-law watching me satisfy myself. I was really getting into it and didn't notice her standing in the room. I ejaculated all over myself. My mother-in-law just stared in embarrassment. I just smiled.
