She's hopelessly erotic. It's no exaggeration to say that at this age she knows men inside and out, knowing all the right spots for them. She also enjoys sexual encounters, coming at them from the get-go. She must really love cock, because even while she's giving him a blowjob she licks it while smiling and saying "it's tasty." In this girl's case, it's not the "tasty" kind of thing you see in porn... she really loves cock. Seriously erotic girls are really exciting.
