Take a look and see

The list of people Erin wants you to ruin or mess with is quite extensive, it ranges from her freshman year dorm roommate, a former undergrad student who is now a TA at the University, a random bartender down in the Collegetown pubs, and even a few of the local citizens who call this university area home. Erin makes it explicit, deeply explicit, that she is never to be mentioned if you interact with these people, and that her or the Delta Delta sorority name should never be mentioned around any of these targeted victims.

Do you get to fuck some girls?

Oh yes, Erin has brightly engineered these target dossiers to pertain to your interests: that is, the girls on here get to be fucked, or you have freedom to sexually mistreat them so long as you complete the task given to you.
