an extremely skinny but very very long penis. it penetrates you like a pencil with that sharp tip (def circumcised) but once in you it slithers like a very horny worm. to be pencil wormed is to live like you never have. being pencil wormed is an honor. cherish it.
Nicci: how was he?
Megan: holy shit he pencil wormed me all night long...
Nicci: UHH D'NOH D'NOH...
Megan: i know.
