Was there ever interracial sex with slaves and owner's wives/daughters?

This is a serious question and I always wonder about that. I know it's true that the owners impregnated female slaves to sell more babies......but.....has there ever been a case where a male slave secretly had intimate relationships with the owner's daughter or wife? I know you see stuff like this in movies, but did that ever happened in real life in the 1800's? I'm not being racist or trying to start trouble, so please don't take my question the wrong way. This is something I wanted to know.
