sister pukes uncontrollably after tricked into blowing her brother
LOL - so here's the back-story. This brother & sister are total assholes and overdue for some revenge. The sister is offered $1000 bucks to blow some guys in a fake redneck incest gloryhole & the brother is offered a free blowjob from some whore - unknowingly his sister. When the sister realizes she swallowed her brothers load, she pukes her brains out.
