These hostel girls are much worried. One of their roommate is feeling sick and wanted a treatment. So, she tells her friends to call a guy who is her friend and a doctor as well. When one of her friends called him, she feels aroused listening to his voice. Look at these desi girls talking in double meaning.
When she was alone in the toilet, she sits on the pot thinking of that voice. Fingering her pussy, she inserts her hand into the bra to press her boobs. When she tried to masturbate, the doctor arrives and she takes him to his room. There, she takes off all her clothes and begins to ride his penis and you can see her boobs shaking nicely.
