Mother masturbate story

She did it incidentally. The next thing I remember is my mother yelling from the staircase, which led directly into our living room. She had been discreet and modestly kept it from view. I told her I must have sleepwanked and it was common! She was a sexual creature after all. While she was cutting my hair I was masturbating and she didn't give a shit. Where was the harm in that?

I came over her and she guided me into her. My other hand landed onto her right thigh and her hands rummaged through my semi long dark brown hair, letting it slide right through her fingers. I chose the latter. Now a year later I am 19 yrs old, 5' 10" in height and weigh in at lbs and doing good in College.
