Two hotties roughly bullying a nerdy college mate

Jack is a class nerd. Always reading books, never going to a party and always doing everything way ahead. There is a exam in few days and Jack is of course pre-calculating all kind of formulas and he's preparing for it. Daniela and Ester on the other hand are the popular girls - they are at every party and they don't really like college so they don't prepare, they just somehow float threw the college with help of others who hope get close to them. But these girls don't need any more friends. They are spoiled, bratty and they think they own the world. But today they need some help with the exam and Jack is excellent source of answers. The girls approach him while he's alone in library and they want his calculations. But he's so honest he don't want to give them anything. Everyone should do their own work, he says. It would not be fair to give it to them. But the girls have enough.
