Mizzy crept up behind Heath, smiling softly at the moaning Traci before she pressed herself against his firm back, her hands caressing his well muscled chest as her own soft breasts pressed against him.  Sliding her hands down his sides slid them along his cock as it began to disappear into his sister.  Resting her chin on his shoulder she whispered soft encouragements in his ear, mixed with her own promises as to what she would do for him.  She rolled her hips against him, speeding up the pace of his plunge slightly, Traci's gasps of pleasure music to her ears.<br/><br/>She rested her head on his shoulder for a moment before kissing the hard flesh and walking around to the other side of the bed, leaning down over Traci's lolling head to kiss her upside down mouth, slipping her tongue past those panting lips as her hands lightly caressed Traci's slowly bouncing breasts.
