Meet Lisa Tiffian. She's studying for her Master's Degree in Human Sexuality, and she's working a her thesis. Her study today is drawing a sample of white males, ages 18 - 35, and she's measuring things like penis size (both flaccid and erect), testicle size, as well as volume of ejaculate. Someday she hopes to be Dr. Lisa Tiffian, Sexologist, with her emphasis in the white man. See, she's a white cock slut, and her \"studies\" give Lisa an excuse to display her slutty behaviors in the name of research, education, and humanity.
