Fuck Katherine while Sabrina is awoken

"Breakfast is ready," you hear Emma say as Katherine's head is still bobbing in your lap.

"Good, I was just getting bored," you say giving Katherine a slap on the cheek. She yelps but continues to suck on your dick like a good little slut, "Go wake Sabrina up, she's overslept and needs to eat."

Emma nods at your command, and you pull Katherine's head off your cock. She gasps as you grab her roughly by the hair and shove her onto the bed alongside you. You turn around and before she has a chance to do much of anything, you're on top of her, your cock rubbing against her opening for the second time this morning. God, how you love fucking these girls whenever you want.

You push into her tight pussy and start pumping in and out, hard.

Sabrina walks into the room, rubbing the sleep out of her eyes, her naked body thin and toned and begging to be fucked. She's definitely the sister you have the hots for and when she spots you fucking the shit out of her sister, you swear you see a pang of jealously and anger flash across her face.

"Good morning Sabrina, good of you to join us," you say as you keep pumping Katherine's wet pussy, "Your little sister was so kind as to make us all a nice breakfast. Your bodies are going to be getting a lot of usage today so I figure we'd all eat up."

You decide to add a little extra competition to the mix given Sabrina's desire to be first and best, "And I was thinking, the sister that makes me cum the most this morning, will get off easy this afternoon. I'm pretty imaginative with my punishments as you know."
