Fuck, she barely even slowed down. She 100% chose dick over her family, and didn't care if they heard or not. Idk what they said, but she didn't even care enough to reply. Not even to tell them to go away. They could of been there the whole time, hearing everything, and she didn't care.
Only way the could of been better, is if he told them to get lost while he fucks their mom, or told her to tell them to fuck off while she gets plowed.
The fact they never knocked again means they absolutely heard the sounds, and knew what it meant.
