He catches her mid-act, and their argument turns heated, with Dolly hurling insults and her brother pushing back. They decide to relieve their tension with a hardcore hate-fuck. Dolly's tight, wet cunt takes his thick cock roughly, her moans filled with disdain and lust. Clothes tear as they pound each other, their bodies glistening with sweat, until they're interrupted, leaving them breathless and unsatisfied.
