a fat ugly girl

You look around,wanting to choose the least dangerous of the group. You notice an unattractive girl, very fat, with big but very saggy tits.

She has dark hair tied in a long pony tail and wears nerdy glasses. She has a mouth with thin lips that pout open a little, so you can see her teeth through them.

The girl's doesn't attract you at all, but she doesn't look as excited or aggressive as the rest of the crowd, so you choose her hoping she'll not milk you dry in a brutal way, probably not having the experience all these other girls seem to exhibit.
