Essentially you pump around three litres of ice dragon cider into your nasty girlfriend's arse which you then plug using your member, hanging onto her hair (preferablly pig tails) you shake that bitch up like a
fizzy drink then ride her half way down the stairs. At this point pull out and let the ice dragon propell you both towards the bottom of the staircase. Pull hard on her hair and try to face plant that tramp against the door. If
successful, teeth marks will be evident along with her bloodstained face.
