Not all of this work is Tenchi Muyo, only the first third I'd say, with one last image of Ryoko tacked onto the back cover. Not much story in the Tenchi segment, mostly just random images of Tenchi(Or assumed Tenchi as some do not portray the face of the male) having some pretty intense sex with one female character or another, although Ayeka and Ryoko seem to be the favored, the rest getting only a few each. There is a hint of Bondage and piercing, but the real element is the agonised faces on the females. They do not appear to enjoy this at all. The rest of the Tenchi segment details Tenchi sexually punishing Ryoko in various ways including strapping her arms to the ground.
The second part of the H-Doujin details charcaters from a series unknown to me, although the female is cute enough on her own to sustain interest. It starts off innocently enough, with straight-forward sex, only to end in group rape with the girl looking extremely uncomfortable with the arrangement/betrayel.
Part three details a Samurai Showdown couple, again, mostly rape appearances and discomforting expressions make this one feel slightly sickening rather than arousing.
This is followed up by a Street Fighter orgy, the girls for once enjoying themselves except for Chun-li. It's too bad this one is so very short and not very detailed.
The intensity is good for the most part it makes the characters look like they are really feeling it, I just wish it didn't look so much like rape, after all don't most of the Tenchi girls want to sleep with him anyway?

First of all, not all the works in this is Tenchi. Second, the art is surprisingly bad. To be honest, some of the characters COULD be from Tenchi, I just can't really recognize them.

The first work is with Washa and ... Ayaka? It's hard to make out what's happening but it's forced sex. It's not very good and pretty boring.

The second story seems to be group sex with.. a Wedding peach. It's pretty good and the art is clear enough to make you interested.

The next few are very cluttered and incoherent. The sex is boring and the people are ugly. But they are not Tenchi characters.

Thus, the only story worth it in this doujin is the second and its too short. Skip this.
