It's a little embarrassing to admit, but I jack-off to my own home surveillance videos
Is there someone in the videos that makes you want to do that?
Seeing my housemates is fun to me, I don't feel ashamed about it
If other people live in your house then you should respect their privacy. Masturbating to people who are unaware of people using the tape like that is very immoral.
I don't care about my housemates. I'm going to continue.
I really think you need to stop. It's really a violation of their privacy and trust to use the videos to pleasure yourself. Would you want someone using a video of you in that way?
