Guy and girl meet at the Bar and are instantly attracted to each other.
They Party all night and at the end decide to go back to his place to
continue. Once there, they get passionate and start to make out. When
the time is right, the girl finds the bedroom, gets undressed an gets
under the covers of the bed, waiting for the guy who is now coming out
of the bathroom.
The guy walks in starts to undress an stops with just his shorts on, he
reaches into his pants pocket an pulls out a magic marker and hands it to
her.
She takes one look at it an says, "What's this for ....are you some kinda
pervert?" He looks at at her, drops his shorts, and smiles kinda sexy.
She smiles, her eyes now wide open and staring in disbelief at his penis
which hangs more that halfway to his knees.

She then hears him say, "Your
gonna have to draw a line somewhere baby".
