DKM makes it 3-0

Tall Sarah was well ahead of Lisa by this point, but the Bro who planned to plant his seed in her wasn't far behind. Sarah ran well, but Lisa could tell from her body language that the sounds of her sisters being fucked into submission were affecting her.

"You can do it Sarah!" cried Lisa, though she honestly wasn't sure if this was true. The Bros had gained on them so fast. They had been overconfident, and Felicia and Beth were both paying the price with their pussies. They were now just trophies for the frat boys.

And, Lisa began to realize, the same thing might well happen to her. She imagined how that moment would feel when the Bro grabbed her and she went from free indominable Lisa to Lisa the fratboy cumdumpster. She wondered how it would feel when strangers laughed behind her back at her conqueror's marks on her ass, and...

...she realized she was slowing down, already surrendering to the douchebag behind her. No! She **** herself to speed up, running even faster than she had before!

Sarah, sadly, was having the same thoughts. Lisa watched in shock as her sisters shoulders slumped. She slowed down, got down onto her hands and knees. She undid her bikini bottom with a whimper, stuck her ass in the air and waited to be claimed. Soon, and with little ceremony aside from marking her ass, she was. Her moans joined Felicia's and Beth's, and they were the most submissive of all.
