Bree was annoyed by Bob when he touched her body like some kind of perv. She teaches him a long hard lesson with her scissors and ball busting techniques. She even smothered his face with her crotch. She chokes with her hands as well as her feet and also grinds her feet into his crotch at times. She had no mercy and she seemed to have had a bad day and was taking it out on Bob. Too bad for him its gonna be a long day after she is done with him. Aside from her attitude you can tell she enjoys hurting him so perhaps she this is her way of relieving stress.
