so when i was younger i would often masturbate in the shower like a normal teen boy and i would kind of just let it go on the floor of the shower and not think anything of it. 

one certain day before school i had just finished jerking it and i released on the shower floor and went on with my morning. now after my time in the shower my sister got in to take a bath and would always come into the living room with my mother would comb and do her hair. 

we are doing the normal morning ritual of watching tv while my mom does her hair and i hear my mom go, "oh god what is this?" while she touches this huge glop of seamen that somehow managed to get on my sisters head. she then proceeds to ask me if i know what it is and i deny it. looking back she knew damn well what she was touching.
