Mizzy groaned as she pounded herself, a thin drop of blood trailing down her chin as she had to bite down<em>hard</em>to keep from screaming.<em>GOD</em>she was so<em>close!</em><br/><br/>The thought of Traci and Heath on the other side of the thin door, touching each other as no sibling was meant to was driving her wild.  So wild that she almost missed Heath's pronouncement.<br/><br/>"I'm going to have my way." she heard from behind the closed door, and a shiver ran through her as she recognized the absolute sincerity in his voice.<br/><br/>Her heart was suddenly ice, all of her fantasies banished like the morning fog as her hand gripped the doorknob and a snarl crossed her beautiful face.  She loved Traci, and only that love held her back now from storming in there, her ears desperately listening for some sign of Traci's response.<br/><br/>At Traci's shouted "NO!" Mizzy barges into the room, coming up short with a deep crimson flush in her cheeks as she sees the tableau before her.  Traci's hands on Heath's chest, trying to push him away as his cock hung from his opened pants, pressing against her thigh.  With a muttered curse Mizzy strode forward towards the pair, cursing her hesitation.
