Kurobara shôten (1975)

Kurobara shôten (1975), also known as Black Rose Ascension, is a Japanese drama. It is directed by Tatsumi Kumashiro, and is based on a novel by Giichi Fujimoto. That must be a one heck of a book if the pervformance by Naomi Tani is any indication of its hotness. The scene we're thinking of, honestly since we've seen it there's little else we can think of, is when Naomi is underneath a man, who is on all fours like a dog, and Naomi, like a dog, is between his legs and licking him up his crotch and to his belly. He must taste awfully good because she can’t stop, and even tongues the old guy’s anus, both of them making the sounds of pleasure. Depending on how you define pleasure, you’ll moan too.
