Days in the Dorm
Chickens Never Win
You can't do it. You can't risk upsetting her or, worse, losing her as your roommate and never seeing this sight again. So you stay quiet and just watch as she gets dressed and heads out to her class again. Once she is gone you do your usual masturbatory activity and then get ready for you day as well.
Unfortunately this action, taken for a third time, has set up a precedence in your mind and made it much easier to pass on opportunities when they arrive. Although you are highly attracted to her, you don't act on it and watch as Sam finds several boyfriends and girlfriends over the next year. You become her best friend and always there to support her, but never try to take it to the "next level" for fear of losing what you have.
She even becomes so comfortable with you that you don't have to sneak peeks at her in your half sleep mode. She starts changing right in front of you, often while holding conversations with you about unrelated topics, and doesn't seem to notice what it does to you.
You have become "like a brother" to her and lost any chance you had of ever getting into her pants. Your school year passes on and your frustration grows, but remains internalized. You never get what you really want and this story ends up going nowhere it was meant to.
I guess that mean that you can't be too much a chicken if you want to win in life. Chances have to be taken. That doesn't mean you should go crazy and take great risks, but some risk is needed to succeed. None of that matters now, though, since this is the end of your tale.
