bloodninja: Ok baby, we got to hurry, I don't know how long I can keep it ready for you.
j_gurli3: thats ok. ok i'm a japanese schoolgirl, what r u.
bloodninja: A Rhinocerus. Well, hung like one, thats for sure.
j_gurli3: haha, ok lets go.
j_gurli3: i put my hand through ur hair, and kiss u on the neck.
bloodninja: I stomp the ground, and snort, to alert you that you are in my breeding territory.
j_gurli3: haha, ok, u know that turns me on.
j_gurli3: i start unbuttoning ur shirt.
bloodninja: Rhinoceruses don't wear shirts.
j_gurli3: No, ur not really a Rhinocerus silly, it's just part of the game.
bloodninja: Rhinoceruses don't play games. They fucking charge your ass.
j_gurli3: stop, cmon be serious.
bloodninja: It doesn't get any more serious than a Rhinocerus about to charge your ass.
bloodninja: I stomp my feet, the dust stirs around my tough skinned feet.
j_gurli3: thats it.
bloodninja: Nostrils flaring, I lower my head. My horn, like some phallic symbol of my potent virility, is the last thing you see as skulls collide and mine remains the victor. You are now a bloody red ragdoll suspended in the air on my mighty horn.
bloodninja: Goddam am I hard now.
