In this scene, we are introduced to Kii the Dryad, although she is much angrier and larger than she's supposed to be. With her currently bent on revenge against the humans that have been ruining her forest, it's up to Godzilla Suu to stop her, with a little help from Darling and Papi. With the strange nutrients that were dumped in the forest driving Kii insane, though, there's only one way to bring her back to normal: extract the contaminant manually. And how does one extract fluid from a tree? Through its...breasts. Don't overthink it.

Starting off with what appears to be a giant monster attack, Papi is the first to be trapped by Kii's oddly ecchi vines, digging into her in all the right places. When things start looking bad, giant Suu jumps in, using her now ridiculous boobs to keep Papi and Darling safe. Back to saving Kii, Papi is quick to get to work on extracting the contaminant, suckling on Kii's impressive chest, before being captured again by the now even tighter vines. Finishing off what Papi started, Darling takes over breast sucking duty, while a desperate Kii starts trying to stick the nutrients out of Suu's chest. The scene finishes nicely with a three-way, sucking, bondage explosion as all the girls reach their peak.

Ecchi series often introduce themselves quite nicely, with a display of some of their finest fan service to start off the show. In this regard, Monster Musume is no different, with its opening scene bring one of Miia's best, as well as one that benefited greatly from the uncensored Blu-rays. In this first scene, we see both Miia's cute and clingy personality, as well as her ability to crush the life out of puny humans without even trying. Although fairly vanilla for an ecchi series (particularly one about monster girls) this is definitely one of our favourite snek scenes.

The scene starts with Miia sneaking into Darling's bed to steal some of his body heat, all the while her clothes ironically seem to be falling off of her. Despite falling back to sleep, our sweet snake girl continues to gasp and moan as her breasts are squeezed and wakes up pretty promptly after her sensitive tail gets a good tug. With her weak spot now under attack, Miia's moans get louder as she begins to sweat and saliva leaks out of out the corner of her mouth. Not long after that, she reaches her climax and quite literally finishes Darling off. Who doesn't want to wake up to a cute, soft chested lamia girl crushing their insides?

The final female addition to the series, headless Lala's chuunibyou delusions, while hilarious, cause both her and everyone else a heap of problems. On the flip side when she's not being chuunibyou she's pretty cute, and her head being detachable leads to some erotic, if strange, incidents, one of which being this scene from her debut episode. With her body currently in the care of the monster girl household, and her head currently who knows where, Darling and co. go out in search of Lala's missing portion. With reports of screaming bringing the police patrol over, though, and Darling now walking around with a seemingly severed head, things start to get awkward when Rachnera decides to have some fun with Lala's body back home.

As well as some fairly ordinary ecchi scenes, Monster Musume also has some of the stranger ones out there, including this one. While Rachnera practices her bondage on poor Lala's body back home, elsewhere she starts to really feel its effects, with the spider silk ropes digging in between her breasts and thighs. Even with Darling trying to keep her quiet, Rachnera's ropes only get tighter as Lala struggles to keep her moans from escaping. We then we reach the best part of the scene, as Lala starts sucking on Darling's fingers and drooling as she reaches her limit. Amusingly, the ero suddenly comes to a halt there as Suu stops Rachnera's fun back at the house, although we do get some nice shots of the slimey young girl playing around with Lala's body as a bonus.

Is there a name for someone who's cosplaying someone who's cosplaying as them? That sounds like it could be a thing. In this scene the girls have turned on stalker mode to find out what Darling is up to, hanging out with Smith on what looks suspiciously like a date. Among their disguises for the mission are mermaid maid, two very well endowed ice cream salesgirls, and Suu and Papi's costume of a human, cosplaying a harpy, a disguise which is almost too convoluted to doubt. Of course, even the best-laid plans of mice and men are no match for harem genre tropes, and each disguise fails miserably in its own fantastic way, with Suu and Papi's being the cream of the crop, involving a poorly placed mobile phone, and a pair of hands that Papi can't control.

After Suu (Papi's new arms) accidentally drops their mobile phone into herself (Papi's new breasts) she has a surprising amount of trouble finding it again, aggressively caressing her chest in order to force the thing out. As Suu continues to struggle, she works her way down Papi's body, finally reaching under her skirt, which she decides is a good place to stop and rummage around for a while. As the phone now finally slips down inside Papi's panties, Cerea decides to make the fatal call, with the phone's vibrations pushing the little harpy over the edge. Regardless of what's on the screen though the best part of this scene is actually Papi's voice throughout, as she struggles with Suu in between breathy moans.

Even among the monster girls, Suu is a bit of a black sheep. Largely incapable of talking or thinking for herself, she's an odd combination of playful child, and big boobed, intelligent onee-san. As the slime girl of the show, she is more often than not involved in many of Monster Musume's ecchi scenes. Her second episode where the girls are hiding her from Smith is one of the best examples of this, with her overwhelming thirst driving Suu to scour the other girl's bodies in search of any and all liquids. This "scene" is actually three short scenes, as Suu makes her way through Papi, Cerea, and Miia one after the other, in her noble quest for fluids.

Accidentally spilling a full bottle of water all over herself, Papi becomes Suu's first victim, starting off with a kiss and quickly turning into a lewd licking experience. With Suu quickly enveloping Papi's small body, it's not long before she can't hold out against the slimy caressing anymore and gets finished off. Next is Cerea, who manages to break a nearby tap, drenching her back-end with water. Yet another easy target for Suu. Starting with Cerea's lower half, Suu swiftly slides her way up to extract the liquid from Cerea's soaked breasts as well, with Miia all the while trying to muffle the poor pony's moans.

Lastly, Miia herself foolishly lowers her guard and gets jumped by Suu from behind, with her sweat being enough to spur the slime on. Getting a good grasp on Miia's sensitive tail, Suu has no trouble licking her dry, all while Darling watches.
