"That's probably a good idea." Heidi gestured to the spells Tracey cast. She finished pushing the blonde's shirt up,pulling it over her head and tossing it to the floor. "Mm. Much better." Heidi then attacked the newly exposed skin of Tracey's collarbone.
Heidi lifted her arms so her shirt could join Tracey's on the floor. "I have a feeling I'm about to work even harder." She mumbled as she returned to her assault on the Slytherin's collarbone. Her hand ran up the smooth skin of Tracey's side.
She grinned at the sounds she was coaxing from the girl beneath her. Slowly, she let two fingers slip inside the damp folds and start a steady, firm pace.
Heidi let their tongues do battle while she worked her fingers in Tracey, thumb tracing the girl's clit.
