Hilda's a blind cello student - but that doesn't mean she's not horny. She can't see, but she can smell the scent of sex, and hear the gasps of pleasure as those around her. A flute player gets eaten out as she sucks on her flute until the music professor shows up - then she starts sucking on his cock. Then d.p.'d. Then she decides she needs both cocks in her mouth and two loads of cum on her face.
Hilda goes back to her apartment, where a taxi driver and his stuck-up fianc'e are testing out their bed. Later the taxicab driver comes over to Hilda's for a chaser.
The taxicab driver gets called to pick up the professor, and we flash back to reason for his upcoming divorce a pretty good four-way that didn't involve his wife which culminates as a d.p. and with a solo accompaniment.
Later there's an even better four-way to celebrate the divorce of the professor - over at Hilda's apartment while she's out getting her eyes operated on (which will restore her sight). Two girls get pounded by the cab driver and the professor - then both girls catch cum in their mouths and swap loads as they make out.
Hilda comes into the apartment, finally having her sight back - just in time to see that climax. Cut to the cab driver getting married - but Hilda shows up and he leaves that stuck-up bitch at the altar.
The audio dubbing is laughingly bad. I recommend turning off the volume and just watching the sex.
