Cat scratches

With your head being pinned under Rosies ass it's not possible to lift yourself up and your Aunt takes advantage of the situation right away. Her hands quickly find their way into your shorts and underwear, and her fingernails roughly grip your buttcheeks before grinding their way roughly up your back. She repeats her ****, this time starting in the small of your back and scratches all the way up your neck, it hurts more than it tickles.

Soon your back is covered in thin, red welts; a sight that, not only makes Rosie happy but, renews her will to fight. She slowly takes her time raking her nails up your back, reveling in the sight of you squirming (and failing) to free yourself.
