Eri-chan is a serious, model student. She's not just doing this for pocket money, but to save up for her education. Her serious personality is contrasted by her careful fellatio, and the way her usually expressionless face contorts with pleasure is incredibly arousing. She's definitely a masochist, and you can tell that her vagina is clenching unconsciously, and that she's really just satisfying her own desires. I got to enjoy raw cumming inside her, something her boyfriend has never done to her.
