The other version is uncensored, has nipples, the episodes are ~5 minutes long and contain sex scenes that are not even vanilla hentai or borderline hentai, but real hardcore porn. Oh yeah, and genitals are still pixelated because let's face it, if hentai was uncensored, people wouldn't bother watching real anime anymore.
Story:
Dude sets into a new apartment just to see a girl upstairs fall through the floor (or rather, the ceiling from his point of view). Just so happens to be, she directly lands on his erected dick and a penetration occurs. This makes the landlord (girl, duh) super worried, so she gives her room to this girl whose floor is now broken and sets living with the guy-dude-person... and then they fuck. Everywhere. Living room, shower, even in their sleep. However, the dick-landing girl is now also super interested for some more action, so naturally, we have an epic setup here for all sorts of plot related... things.
Characters:
The dude is quite typical, horny anime sexual... until they bang, which makes him seem like totally different character in the censored version. Landlord seems to be pretty good at sucking dick, and the other girl really did a perfect dick-landing with telemark and all so I am not sure what else anyone could hope. The characters are vastly different based to the version you're watching, but practically, in the porn version, they are kuzu (trash) and lustful sluts while in the censored they are closer to characters seen in ecchi harems that center around teenagers and have shonen target audience tag on them.
Production:
Somewhat uncommon production values and execution in generally for a hentai title. The animation budget seems to be above what is usually spend on porn. Background art contains more detail and overall just seems much more anime than hentai. Even the fov (field of view) is more of the anime sort than of the type that is usually used in sex scenes. The actual lewd action is rather unimpressive. The basic ecchi scenes are more successful than the ridiculously short sex scenes.
Enjoyment:
I like anime tiddies, and have to recommend to everyone who appreciates them nipples because this is a must watch for that matter. The censored version is still funnier to watch so I can't really say which one you should aim for. There is plenty of hentai that actually put an effort in the sex scenes. On the other hand, it's not like anime industry is short on ecchi comedies either. I watched both so maybe do that. It's almost educational when you see how different anime can become when you insert one dick in there. heh sexual innuendo
