Flimed while getting off

Vanessa began filming. Lauren, obvious, kept masturbating. Face down on the couch her hand pressed hard over her clit as it ran back and forth faster and faster. Her rock hard nipples pressed the couch. She buried her face to suppress her moaning. Vanessa watched, phone filming, as Lauren thrust her hips down over and over again. She covered her mouth to suppress a giggle. Lauren's thick butt was flapping back and forth, shaking like a bag of jello rolling down the stairs. It was THE most undignified she'd seen her sister yet... and she was recording it! This was the ultimate **** for the years of cold treatment from her smug, superior sister.

Suddenly Lauren climaxed. It was so abrupt she wasn't even expecting it. Her suppressed cry came out as a chortle to Vanessa as Lauren's whole body spasmed with pleasure. Then she sank down, utterly relaxed as Vanessa stopped filming.

It took Lauren almost a minute to recover. While she did Vanessa put her phone away. Finally Lauren raised her face, which was red and sweaty, hair wild and matted to her face. She huffed with exertion, feeling the ecstasy course through her. That was a goooood one.... she though, biting her lip at her own naughtiness. She couldn't believe she had just masturbated in her living room to her rival boning her crush! Her pleasure was so great, she didn't even realize the noise from the other room had stopped. That was, until the door creaked open and Britney and Mark stepped out...
