Heidi chuckled at Tracey's answer. "Well then, I think we should remedy that. I don't want you to get too hot with these warm clothes on." Heidi told her and ran her hand up Tracey's stomach to just below her brest, pushing the sweater up with it. "I vote for removing a few layers."
Taking that as all the permission she needed, Heidi began to let her hand snake around to the front of Tracey's knickers, "If you insist." She teased and let her fingers brush against Tracey's folds and across her nub, circling around it gently.
"You really want this, don't you?" Heidi teased again, feeling Tracey's arousal. She smiled at the fact that the smartest girl in class might actually want - need - something from her.
