I can't read Japanese, but from what little I can glean from the manga, there are two stories here. The first one involves a princess-mage/healer-type girl who stumbles out of the bushes upon two guys (perhaps her allies/companions) eating by a campfire. She collapses upon seeing them, looking exhausted and with her clothes torn to shreds. And with this she begins to recount her earlier ordeal of being attacked and raped by two frog-men in the woods. As the cover suggests, she gets impregnated with tadpoles, which upon the conclusion of her story, are expelled from her prolapsed uterus to the shock and terror of her compatriots.
The second story is centered on a warrior-type chick who has a broke sword which is missing most of its blade. She, and her companion, are attacked by a faceless mass of tentacles, which, unsurprisingly, she's unable to fend of with her useless broken sword. Instead, she too gets raped and impregnated, but this time it's caterpillars or silk-worm-like creatures that crawl out of her womb.
Both stories are pretty short, but the first one isn't bad. The artwork is fairly detailed and clean, with lots of the expected tentacle-rape (impregnation, double-penetration, nipple-rape, etc.) action. However, the second half of the dōjin is of much lower quality. The line-work and cel-shading are still very clean, but the art is much less detailed and the proportions are quite off in places (not just the usual stylistically exaggerated anatomy). There are a few panels that look alright and almost as detailed as the action panels in the first story, but in general the second story has a very rushed feel to the artwork--in particular, the faces of the characters (of which there are just the two females in the whole strip) seem to have been given short shrift. However, the cutaways in both stories are well-drawn and used to great effect throughout the short work.
So, to summarize (using a 10-point scale): Art-work: 7.5 / 5.5 Story: 5 / 3 (just too short to carry a good narrative, but then again, I couldn't read the dialog)
BTW: Can someone give the Romanized name of this work? The title just shows up as a bunch of squares or random characters on non-Japanese systems.
