"Of course...I am." Heidi breathed. Ginny was blocking her view of Tracey, but Heidi reached for Tracey's hair and soothingly stroked it, urging her lover on.
As Ginny pressed a little more, Heidi moaned, the moan being caught slightly in her throat as she breathed a little harder. Heidi's eyes locked with Ginny's as her breathing adjusted.
"Yes." Heidi said, her voice obviously giving away her position under Ginny. she struggled a bit more to free her hands, but Ginny's legs kept them by her side, except for the hand that could just reach Tracey's hair and it was still playing with the girl's blonde locks as she tried to move her hips to meet the Slytherin's mouth.
Feeling Ginny grind on her abdomen, Heidi tried her best to arch into it to help Ginny along a bit.
