Haley barges in

"God damn it, Luke!" cried Haley as the door flew open and she barged into the room. "Do have any idea what you've done?"

Luke sat straight up with a look of terror on his face. His heart was pounding, but he was too shocked for words. He had just been caught getting a blowjob from his sister BY his other sister.

"Guess playing hard to get doesn't work on Luke," said Alex with a smirk on her cum coated face. She began to slowly scoop the cum off her face and into her mouth savoring every drop.

"Wh-what?" Stammered Luke trying to figure out what was going on. His cock twitched as he watched Alex swallow his cum.

"Gah, you're such a dweeb, why couldn't you just have come downstairs like I wanted," cried Haley slumping onto her bed with her face in her hands across from Luke.

"Bet's a bet, Haley," said Alex standing up and putting her hands on her hips.

"I know, I know," said Haley looking up at her younger siblings. Luke still had no idea what was going on.

"Good, now get on your knees," said Alex pointing at the floor. Luke couldn't believe it as he watched Haley did as she was told. She slid off the bed and onto her knees.

"WHAT is going on?" Exclaimed Luke.

"Alex and--," began Haley before being cut off by Alex.

"No, you will only speak when I tell you," Alex said to Haley forcefully. "Understand?"

"Yes," said Haley looking down at her hands on her lap.

"Yes, what?" Asked Alex.

"Yes, mam?" Said Haley looking up.

"You will call me mistress from now on," said Alex walking over to Haley. "And to answer your question, Luke. Haley and I made a bet on which of us could give you a blowjob first. The loser has to be the winner's ****. Isn't that right, ****?"

"Yes, mistress," replied Haley looking at Alex.

"Good girl. Now what to do with you," said Alex as she rubbed Haley's right cheek with her left hand.
