I remember when I was like 10 year old (now I’m 28) watching a movie where a fat woman forces another woman to give her oral sex, they are in a prison, and they are in a pool or something like that, and after that scene the fat woman slips and fall.
Also I remember that the fat woman was in prison because she killed and ate her husband.
The year is off a bit, but the description mostly fits…
