Kama Sutra also goes by Kyuukyoku no Sex Adventure Kamasutra. The 60s/70s animation through me off, but this is a 1992 one episode OVA. It’s 42 minutes long. It was adapted from the manga Kamasutra. Kamasutra is four volumes at 21 chapters and was published in 1990.
Hidden deep in the ancient Himalayan Mountains, a beautiful princess is found in the ice. Dr. Aikawa revives the sensual princess in his own special way. Now that the lovely Princess Surya has been brought back to life, the fun begins. With love struck eyes, Ryuu, Dr. Aikawa’s son, decides he must master the 48 positions of the ancient art of love, as described in the classic Indian text, the Kama Sutra. Little does he realize how much trouble a beautiful princess can be, until he finds he must protect her from the vicious Indian cult, the Mali Clan.
So this show is about how a Hindu Princess is revived after centuries with the science of Semen and love juice inside a sex cup and she comes back to life and somehow she has to have relationships with the grandson of some archaeologists for some reason. I saw this title and wondered just how racist this might go. For this old film went with the approach of not blocking the sex parts but positioning the characters in situation where they would not dangle (show).
