Aria Arial gets called into Professor Knight´s office hours because he has a special offer for her: he asks her for her help on his doctoral thesis on human sexuality. Aria is honored to be asked, but when she discovers that he´s doing it on the sexuality of a college student, i.e. Aria when she´s got his big dick and balls inside her mouth, she´s a bit reticent. But once she tastes that cock and feels it inside her wet coed pussy, she can´t say no! She knows how to get ahead!
