As much as she would've liked to, Gina couldn't participate in the orgy tonight. She was a week behind on studying and needed to cram. 

Fortunately, she and her girlfriend had worked on making her left hand a fully autonomous sex toy for just this kind of occasion. 

Gina sat in the only well-lit corner of their dorm room, concentrating on her Macroeconomics textbook. Her right hand would occasionally flip a page or scratch an itch under her noise cancelling headphones. Intermittently as she scratched, she would catch a sound and look up in idle curiosity at what her left hand was up to. Often the hand was just fingering someone or jerking them off, but earlier tonight she had seen a very talented brunette (Jenna? Jamie?) taking in the entire lubed fist. 

Impressive.  

Gina made a mental note to make sure what's-her-name was invited to the orgy after midterms as well. Gina sighed. She preferred these things much better when all of her could be involved.  

Oh well, she thought, looking down. Only 3 more chapters to go.
