Rectal intimacy. Maybe the women I know will go for it now. I've never quite heart it put that way before.
This is the terminology used by our narrator/leader/sex therapist/rap session boss Jack Baker in Black Bun Busters, the first tape to satisfy fans of both interracial sex and back door entries. And our leader is quite witty, as he has his inter-action group discuss their various interracial anal experiences (as an excuse for many and varied hardcore scenes).
Although in one very kinky scene, Sahara takes it from Marc Wallace while she goes up another man's backside with a strapped-on dildo, the best scenes range from a black guy spanking a white girl to a ho leather anal scene with adult video's first Prince look-alike. However, the rap session at the tape's end, while everyone stays clothed, is the refreshing release from standard porn that made this viewer realize he had indeed, just seen something with an imagination.
