Sometimes.

Sometimes a boy gets naughty and logs in to a personals site.

Sometimes he gets even naughtier and starts to show himelf doing things that should be done in private.

Until some time, a friend of his tells him that another friend of theirs has seen him showing.

He denies.

But there really is no denying.

Because their other friend saw distinct marks in the person on-cam's body and verified them using the boy's other pictures. On another online community site.
