 It was a Friday evening, and the library was pretty quiet.  There were a
few grad students and some profs doing some research.  I had been to the
pool all day, as the weather was really nice.  The only thing I had to do
was to check on some documents in the collections room and scan some books
in the same section.  So I went in during evening hours, dressed in really
short cutoffs and a t-shirt.  I figured I would be in an out in an hour or
two.

   Well, he was there.  I didn't see him at first.  I was scanning the
books when I felt one hand on my bottom and the other on my breast.  I knew
who it was instantly.  He stroked and caressed a bit, then put both hands
under my t-shirt and pushed up my bra.  I just held the scanner with one
hand and leaned against the stack with the other while he played with my
breasts.

   Well, he played for a while, and then grabbed my nipples really hard. 
He tugged them and turned me to face him.  It hurt.  I set the scanner on a
shelf, braced against the stack, and looked away.  I was humiliated,
embarrassed, and loving it.  He looked awfully smug.

   He unsnapped my shorts, unzipped them, pulled them down a bit, and began
to play over my panties.  It didn't take him long to get a hand inside of
them.  Then he pushed my feet apart so my legs would be spread more, gave
my nipples some really hard pinches, and tugged my panties down to
mid-thigh.  Then he went to work.

   Well, I was sort of squirming and wiggling like a fish out of water.  I
know I was making noises, and I was panting.  And I know we were seen. 
Anyhow, when he finished, I took a good look at him.  He had a real
confident grin on his face.  I think he figured he made me cum, but he
didn't.  He just got me very close.  He had me lick his fingers clean, and
then he walked away.  I put myself back together and went on with my work.

   After that, when he groped me, he did make me climax.  I had to really
struggle to keep from crying out, because the orgasms were very intense. 
He was an expert at finding my pearl, and he loved teasing and pinching it.
I think he liked to give me a little bit of pain with the pleasure.  I
think he liked that.  I always had sore nipples and a tender pearl after
one of his sessions.

   He nailed me major league with one other session.  He got me pretty good
the day I was working in the private collections room.  Now, when you
worked in the collections room, you had to keep the door open.  It wasn't a
big room, and it had a small round table in it with four chairs.  He walked
in, pushed the door all the way open.

   I was dressed in real short cut-offs (I have nice legs) and a halter
top. It didn't take him long to get started.  He just walked right up to me
and began to play with my breasts.  It didn't take him long to get my top
off and set it on the table.  He gave my nipples some real rough twists,
and then tugged on them until I was leaning on the table.  And the shorts
and panties came down around my ankles.  He gave my nipples a real hard
tug, and had me bend over.  He also spread my legs by kicking my feet
again.

   So, I was bent over, leaning on a table, and he was fingering me and
torturing my nipples.  When I was close, he stopped fingering, yanked out
his finger, and stuck it in my ass.  I jumped, stood on my toes, and almost
cried out.  I can imagine the expression on his face.

   He kept his finger in there, and then, with his other hand, he started
pinching and teasing my pearl.  When I came, the climax was unbelievably
intense, and I collapsed.  He just looked at me and grinned.  And I know
for a fact we were watched.

   I've had a number of gropes since him, but he was one of the very best.
He was a pro.  He fed off of torturing me.  And I never did find out his
name.

   I had one other grope since his that is really worth mentioning, and I
will tell you about it in the next chapter.
