I would be tempted to pay this much for a girl with a 10/10 body, 10/10 cuteness, and 10/10 attitude. In my experience, this is something extremely hard to find. Although you could argue that it's better to spend that in two sessions with a girl that scores "only" a 7 in all those categories, and I wouldn't find that outrageous.
But, alas, sexyoungthing does not appear to be a 10/10 girl. At least, not me.
