Trying to find an erotic short story, originally from literotica

I remember a whole bunch of details — she was a really hard working student and had been in class all morning, she went to a vending machine and there was a guy behind her who was really good looking. He was Hispanic and said a lot of really sexy things in Portuguese. They started dating but she was a virgin and so one night he said to her that she had to make a decision on whether or not she wanted to have sex with him – but if she said yes when she met him in the college cafeteria then he would not stop no matter what else she said on the night.

Later on, in subsequent chapters he took her and a few of her friends on a trip abroad and he beat up one of the guys who then had to go to hospital and she said something really bad about his dead mum and he tried to get revenge by taking her really roughly.

Have been using the search engine for an hour but nothing has come out of it – any help would be appreciated!
