La puta ciencia

This nerdy teeny is really into science, but there's one thing she loves even more. When a guy she takes to her grandpa's place to check out her science magazines collection asks her what she does in her spare time he gets the answer in a practical way. She gives him a fantastic blowjob and gets fucked like a good slut, then sits on a couch and takes a great cumshot right on her eyeglasses letting hot jizm drip down her pretty face. Wow!
