The question i ask myself when seeing this is if this is really a strange cock or just her boyfriends dick. Lets just assume it is a stranger indeed, that makes it way more interesting. There are sure girls who are slutty enough to do this kind of stuff, i`ve seen them but i must admit, they were heavily intoxicated by alcohol and would suck any dick at that point. Anyway, i do appreciate her bravery to create some panic in a public bus.
