Embarrassing at first then EXCITING!
This happened when I was 14 yrs. old. I had a 4 1/4 inch cock and thick curly pubic hair.
I thought that I was home alone, and felt horny as hell, and decided to get naked and masturbate in the living room.
I'm cut so I need lube to have a pleasurable handjob. If I'm careful and edge I can last about 20 minutes, well I was going at it good when my 16 year old sister came downstairs. She said "what the fuck are you doing jacking off in the living room, I'm going to tell mom".
Well I knew I was in deep shit so I said please don't tell on me.
She said she'd never actually seen a cock before and if I let her watch she wouldn't tell on me, if I would do it when she demanded to see it.
Well she took advantage of the situation, and would bring her friends home and I would have to get naked and let them watch me jerk off.
Well the first few times I was really embarrassed, to have girls looking at my dick, but they loved to see me cum, what with the cum squirting out of my cock.
Well my cock grew to 7 1/4 inches (from all the sexercise) and I liked having the girls watch me stroking my cock and cumming all over my chest and stomach.
I like being watched now!
