does anyone know this film?

many years ago i remember watching a film on late night tv

because they were sometimes horney as hell

anyway one had a scene in where a housewife was sitting alone in her car
reading a card one of her kids had written her

when all of a sudden a big black guy gets in the passenger seat and makes her drive to a deserted part of the car park

where he proceeds to throw her over the drivers seat pull up her skirt
and tear at her knickers then start to pump her tight cunt

shame it end there
but been looking for it for ages now

any ideas ?
