The sound a chubby girl makes when she is being brought to orgasm. It begins as a quite moan that grows until the moment of climax when a deep squeal bursts from inside her.
People studying in the dorm common area heard the beginning moans she the chubby girls cunt was fingered in her room. In a matter of minutes all studying had ceased as everyone sat giggling as the moaning grew louder and deeper. Finally after five minutes there was the familiar deep squeal marking the climax of that nights whale song.
