Meet Dr. Blowjob, Scientist

Some girls approach oral sex with a wild, smoky look in their eyes and try to work the cock into a mad frenzy of spit and skin. Other girls spend years writing dissertations about stimulating the frenulum with the tongue.

Both types of blowjob are great, but sometimes you want the girl who takes things seriously. It's Christmas (apparently, in this video), she's kept her big glasses on, she has a hypothesis about genital stimulation, and she wants you to be the test subject. If you won't do it for her, at least do it for science.
