Giggling, she kept this up for another five... ten, no, maybe it was fifteen minutes. During which you were kept on the edge the entire time. Only when she felt you finally cum did she begin to ravage and rape you, wildly pounding away at you with no holding back. The contrast broke your mind and drove you into a very eager and slutty place. A small part of you wondered how your roommate would feel about this, but the answer to that came when she joined you in the shower and started fucking your face as the other girl kept going. Apparently, they were really close friends, and she was the exception of 'anyone but me' who could fuck you.
Between the two of them, you didn't wind up spending much of your schooling actually learning. Instead, you spent most of it being rutted like a beast by one girl, and teased and tormented by lots of gentleness before the rough side came out and you were reminded just why she was the dominant one... even with your roomie.
You'd definitely have to thank your mom for sending you here. Your life couldn't be better~!
