As Hermione rested her head on her shoulder, Luna smiled softly as the girl seemed to warm up to her. A flush was drawn to her cheeks though as she could feel Hermione's new addition brush against her. She chewed her lip, noting how Hermione didn't move away. Hearing the girl moan softly in her ear, the hand on Hermione's shoulder stroked the skin of the girl's arm softly.
"I could...help give you some relief." she explained slowly. Boldly, she moved her other hand and placed it on top of the bulge in Hermione's skirt, stroking it lightly.
