Looking over Tracey's shoulder, Heidi continued grinning at Ginny before she turned her head and Heidi turned her own head to Tracey's neck, placing hot kisses on the pale skin. Swiftly, her fingers pushed aside Tracey's knickers and two entered Tracey easily because she was so wet.
Laughing lightly as the knickers landed in Tracey's lap, Heidi moved her fingers at a steady pace inside her girlfriend, never taking her eyes off the other couple, even when she lavished Tracey's neck with kisses.
When Ginny's cunt was exposed, Heidi licked her lips and let the hand that was around Tracey's waist come up to lightly fondle one of the Slytherin's breast, eyes still on Ginny.
At Ginny's orgasm and the all to familiar moan, Heidi shut her eyes and gave a moan of her own, breath hitting Tracey's neck and her fingers curled inside Tracey and the ball of her palm pressed against Her clit.
When Katie didn't stop, Heidi moved to pay attention to Tracey's neck, sucking on it lightly. Slowly, the hand that was on the blonde's breast moved to the top button of Tracey's blouse and began undoing the buttons.
