The first is an h-manga where a youngster is in the mountains and finds a naked girl. They have sex and it's hinted that she's not human but the snake god or something and he is spared from being eaten after she finds out he had a charm his grandfather gave him. Obviously his grandfather knows about her and supposedly they've met in the past.
The second is a movie that I saw eons ago where a guy who only drives BMWs will go around doing "justice rapes" or something like that on girls who other people hire him for. Strangely he accepts video games as payment and had a floral tattoo (at least I think it was floral) covering most of one of his shoulders which he reveals when he does his sort of Phoenix Wright moments. I don't remember much other than these details besides the fact he wore suits and was high up in the corporate ladder.
Any help anyone can provide is greatly appreciated.
