I just got out of high school this spring and babysit for a neighbor 4 days every week. There are three kids, Noah is 12, Karen is 9 and Tyler is 7. I am 6'2'' tall and believe they were intimadated by me right from the beginning. There mom works late on Tueday and Wednesday nights so I am in charge of making sure they get there baths. Its no trouble with Kyle or Karen and after a couple weeks no trouble with Noah. I invade his privacy and know how he is not only embarrassed when I see him naked but also is afraid to say anything about it. He has a very large penis for his age and also has began getting pubic hair. I see him naked 3 or 4 times a week and up until mid-June had never seen him with an erection. When he gets his shower I make sure the door is unlocked and it was June 15th when I looked in and saw him masturbating. I just watched and he never saw me looking at him until after he ejaculated. He was so humiliated he almost began to cry as his penis went limp. As he got out of the shower all he did was beg me not to tell his mother. I just said I wouldn't and then said all boys do that. I haven't seen him masturbate since then but have seen him with an erection a couple more times. He still is embarrassed when I see him naked but I don't think it bothers him that much anymore.
