Korean schoolgirl becomes a prostitute by force

This Korean schoolgirl has no choice but to become a prostitute. Her parents are emigrants, they have little money and cannot pay for their daughter's studies, but she is clear that she wants to finish the degree and if she has to sell her body to pay for it, she will do so without thinking about it. Her first clients have been her own classmates at the university and specifically one of them has fallen in love with her. He is the classic posh to which his parents pay all whims, even whores, so his weekly pay invests her in paying for her friend's services. That friendship makes the girl allow him to fuck without a condom, but he takes the freedom to cum inside even if she doesn't want to.
