Words do get around; about how tight her pussy is. To put it to test, her two colleagues broke into her house and helped themselves. She was sleeping, and wasn't aware of her predicament. But she'd soon realized that there was no resisting; she better enjoy it.
The guys fucked her in a threesome; 1 dick each in her mouth and pussy.
Thereafter, there are a couple of more fuck scenes, 1on1, where she was forced to suck on the dick, and fucked in a variety of positions; missionary, doggystyle, prone bone (yay!), and cowgirl.
