Shannon never knew that Erin had heard her that night, having sex with the other girl - whose name turned out to be Christie. The two of them woke up drunk the next morning, and Shannon remembered have sex with Christie but not where or when... and Erin didn't say anything and she didn't want to ask so it just went unsaid. For the most part she just assumed that Erin hadn't been there.
For Erin's part, she was incredibly turned on by everything that she had witnessed, even though it made her extremely uncomfortable. During the next couple weeks she decided to get to know some of the guys around the campus, talking to them and even getting one or two dates. Still, when they kissed her goodnight she found herself wondering what it would be like to kiss a girl, and when they touched her she thought about Shannon's hands and soft skin. It seemed to her that she was almost becoming obsessed with her roommate... something that just didn't seem like such a good idea.
Trying to concentrate on guys, she ended up giving her first blow-job - which she didn't like so much. It didn't smell bad or gross her out, she just wasn't really into it. And when she was eaten out for the first time, she came, but it was while she was thinking about Shannon and Christie with Shannon's demands echoing her in head. 'Eat my pussy you little bitch'...
Taking advantage of the internet she started looking up free porn pictures and things... but she couldn't find what she really wanted; a full out movie. She was turned on by the still pictures, but she wanted to see what it actually looked like, how they did it, how they sounded... but everything she ran into cost something. Afraid to put anything on a credit card, she just masturbated to some of the pictures they found, although her fantasies always ended back up at Shannon's face and body.
One day she was looking through the videos, innocently enough, and wondered what Shannon might have on her shelf. Looking through it she saw a video at the back of her closet and picked it up... it was unmarked, whatever the label had been it was gone, only a few traces remained where it was. Curious, and a little hesitant, she put it into the VCR and gasped.
It was girl on girl porn... the two girls were licking and sucking at each other's breasts, pinching on the nipples. Lowering her hand to her pussy, Erin watched as the two turned into a 69 position and began to eat each other out, the camera kept zooming in on their tongues in each other's pussies. Now she had a real visual for what it had looked like when Shannon was getting eaten out... her fingers got faster and faster on her clit as her other hand reached up to pinch her nipples. Moaning, she couldn't take her eyes off the screen, one of the girls had begun pushing her fingers into the other girl's pussy... pressing her fingers in and out of that tight hole.
