She doesn’t care that he’s her brother because he has a big cock
A complete life—albeit very short—in which you have always been told what you have to do and what you shouldn’t do, is not a life for anyone. But it is part of the culture of her country, it is not her fault that she is Asian and that, that implies, she has to be a girl lacking emotions and feelings. On the contrary, she prefers not to do it and she doesn’t care that this guy is her brother, because he has a big cock and for that reason alone, she gives him blowjobs every morning so that he can have it hard and then she can get on all fours and he can penetrate her pussy. Every day.
