Beth revealed

Though she struggles with all her might, it's not much longer before Beth is completely pulled out from under the bed by her sister and Amber. Panting, both the older girls look down on her young naked flesh.

Completely mortified, Beth looks up with tears, "Fine," she says, "can I go now?" she asks while getting up on her knees and trying to cover her exposed flesh the best she can with her hands and arms.  Though her sister isn't giving her much attention she can't help but notice how Amber is staring at her hungrily.  

 "I don't know," Becky says standing behind her while Amber continues to stare down at her hands, which are covering her pert breast.  "You did interupt us and you know I hate it when you steal my clothes," she adds while looking at her friend.

 "I wasn't stealing your clothes, just trying them on," Beth replies back while standing next to her sister and giving her a pleading look.  Meanwhile, Amber is now staring at Beth's narrow hips and down her long toned legs.  

 "So nice," Amber finally says, while reaching out to rub Beth's bare flesh.  

  "Stop it, I'm leaving now!" Beth says after jumping back from the redhead's advance.  But on getting to the door she realizes that Becky has locked it with a padlock and she doesn't know the combination.  On turning back around she realizes that both the older girls have been staring at her exposed ass.  

 "I think she should stay until we are done, she was here for the begining of the show, she should be here for the end," Amber says to Beth's sister who contemplates the situation before giving her girlfriend a smile.  

  "No, actually, I think she should finish what we started," Becky adds, which causes an even broader grin to spread across Amber's face.  Beth turns to try and get through the door but it only takes a few seconds for the older girls to grab her and throw her naked body on the bed.  She screams and pleads for her older sister to let her go, but Becky only smiles at her as she takes a position above her head on the bed and  holds her arms back.  

  Amber on the other hand has grabbed the clothes Beth had under the bed and, using her bra, has tied it around one of her feet.  Beth, kicking and crying, tries to stop the lustfull redhead but it's not long before her legs are tied to the two bed post, her virgin pussy exposed to the redheads prying eyes.
