Hentai's from the 80's and early 90's, before tentacles, endless cum, sweat, giant tits and low quality artstyle....
These hentais are different. It's not much about straight fucking, but more about humor and the situations. Censoring is humorous, with lighting strikes and objects representing the provate parts.
Just watch this:
I remember back in the 1990s. Staying up until midnight to watch anime on the Scifi channel.
If it wasn't a rerun of fucking Spriggan again it was either Urotsukidoji, Shutendoji, Violence Jack or Adventure Duo.
Urotsukidoji is basically what made tentacles popular.
Shutendoji is pretty much monster and tentacle rape.
Violence Jack is gore and rape (I remember one scene had a guy simultaneously fucking and eating a girls corpse).
Adventure Duo was also monster and (machine) tentacle rape.
Being a kid in the 1990s was fucking awesome.
It's true - I used to watch SciFi in the UK back then too - (Saturday mornings were Tenchi IIRC, other non-h stuff shown there: - Bebop, Gundam Wing, Evangelion, Blue Gender, Outlaw Star, Patlabor movies, Roujin-Z. That's just off the top of my head). Also, there was another channel which showed lots of martial arts movies and some more anime - CNX maybe? can't remember now

The only difference from modern harem ecchi I see is that ordinary girls fall on guy's panties instead of generic MC falling on hot girl's bust or panties. Even if I hate most of today's ecchi, I would rather watch it than look at ugly guy fapping to not-drawn cunt of some random slut without much story or anything.
