Banned in China but a record-breaker in its native Hong Kong, this softcore grot epic has to be seen to be believed – or maybe not, if your sexual politics are more sophisticated than Sid James’.

Ming dynasty nobleman Hiro Hayama is shown the manifold ways of the flesh by creepy sex Yoda Tony Ho.

Nubile concubines writhe naked in Ho’s pleasure cave, huge 💎CG horse cocks – among other things – assault the screen and the general mood is Mortal Kombat meets Up Pompeii, or a sex panto sans song-and-dance numbers.
