Lavender peeked in at Ginny. She was getting bored and was so very randy. She had been all day, with only a slight break when Ginny got hurt, then it had come back with her cute redhead to close to her and so very close to naked.
Once it was night, Lavender decided she should take the edge off a little. Reaching down, she ran a fingertip over the front of her knickers. It wasn't much surprise that they were quite damp.
She kept touching and teasing causing a few soft moans and whimpers to escape Lavender's parted lips. If Ginny heard her...that would be interesting.
If not, she would take the edge off until Ginny was more with it.
