Kari heard the front door slam as Nicole and Christian left. She rubbed the vibrator up and down her pussy, frustrating herself as she couldn't get as much friction and vibration through her underwear. She turned it up to full speed, arching up into the vibe as it surprised her twitching sex. She moaned, grabbing her breast and squeezing.
She pulled the vibrator up and slipped it under her panties, slowly teasing the vibrating tip over her clit and to her convulsing hole. Her underwear was soaked and she rubbed the vibrator over herself in increasingly fast movements, pressing it down against herself.
She pulled the vibrator away from herself, sitting up and pulling her underwear down and tossing them toward the corner of her room before continuing her minstrations.
