 We were both laying on the couch in the media room, my sister and I.  She
was laying propped up on her side by a pillow watching TV.  I was watching
TV off and on.  Quite fankly, I was mainly watching her.  From where I was
sitting I had a perfect view down her shirt which was already low cut to
start off.  And that is how it started.  I was sitting there watching the
curves of her breasts, when I noticed she had her right hand in her pants.
It looked quite natural, almost as if she had just hooked her hand on the
waist band and was resting it there kinda like Al Bundy does on "Married
with Children"; except, this hand was moving!  I didn't really notice at
first, but I could almost see the movement of her middle finger.  I watched
for a minute the it struck me, she was masturbating!  No, I'm not dumb, or
an idiot.  It's just not something you would expect.  In the movies I'd
seen of women playing with themselves, they were always thrashing around
and moaning loudly.  They weren't just quitely fingering themselves, while
watching TV with there brother watching.  Watching!  Wait a second!  Did
she realize I was watching her?
