Lusty Hot Spring

You were sent out in the countryside to complete an important business deal, and after a long day of work you were successful. However, sunset is near and the last bus is already gone. You have no choice but to call your employer that you’ll be spending the night at a local traditional inn, and returning to town the next day.

Fortunately, the inn has an onsen, a hot spring with volcanic water. Your tense back and sore limbs sure could appreciate that ! But little did you know about the arousing effects of that water, and the fact that it’s a mixed onsen where partners encounter and share relaxing intimate nights with each other…



Renown Japanese masturbatory tools maker Toy’sHeart came up with a common anime trope: the mixed hot spring (which actually are very rare in Japan, almost all being gender-separate –which in turn fuels yaoi or otokonoko hentai). Let’s not digress too much about all-gender facilities since, as a foreigner, your main concern when going in an onsen would be to make sure to cover up all tattoos with bandages -even if you’re obviously not a yakuza member.

A busty woman for who I can safely apply the “oppai” tag on the post, holding a white towel, shining out a “newly wed” aura maybe. Visiting onsens as honeymoon ? Could be great ! She’s already wet, which means she was probably leaving (moreso: you never enter an onsen with a towel on, you always go in fully naked)

A bit sad they used the very same image for all the illustration. Not even a chibi version.


Inside the box, a plastic tray holding in place the wrapped onahole, and a 20mL lube bottle of Moisty Lotion.

Nothing uncommon for Toy’sHeart thus, and it’s convenient to have a lube bottle included that can be closed after use. And it’s a good lube too, should be enough for 2-3 uses.


The onahole is a non-penetrated single layer type, made of Toy’sHeart’s “Baby Skin” TPE material. It doesn’t get oily and out-of-the-box it has as good as no smell.

The entrance mimics the shape of a vulva and allows for easy insertion.

The inside of the onahole features a complex twisted ridge structure extending on the whole length of the penetrable area. The overall shape shows three “chambers” who decrease in size the deeper you go. The whole surface inside has tiny ribs.


Each chamber by itself can act as a vacuum chamber, so the onahole sucks increasingly strongly on you as you pull out.

Sliding inside you’re “attacked” with each bump, and you can somewhat feel the spiral sliding around your glans as you reach deeper.

The onahole is flexible so it’s gonna accommodate any penis size, so the average western 14cm is just perfect with the tip just “kissing” the bottom.

I knew I wasn’t taking much of a risk with Lusty Hot Spring, but damn do the ribby ridges feel good ! Even when speeding things up the onahole keeps the pace just fine, stroking you from all sides with each thrust and distinct suction of the chambers.

Lusty Hot Spring may win an orgasm from you within 10 seconds (especially if you used an onahole warmer) but it’s very possible to edge for an hour and let it make you explode when the time is right.

While suction is nice, note however that it creates some sound you may wanna cover up with some music for peace of mind if you’re not living alone.


Especially if you edge for a prolonged time, you’ll have lubricant and precum mixing up and building up foamy, which can in occasions “break the vacuum” during a few strokes, and leak out onto your crotch. Make sure to use a towel to protect your sheets or chairs, and fine-tune the amount of lube for easy insertion and good preservation of the sensations while also limiting the amount of fluids leaking out.

Cleaning itself is very easy: as with most single layer onaholes you can safely turn it inside-out to flush away everything, soaping it up well, rinsing, and patting dry with a microfiber towel.

Additionally, you can apply baby powder on the external surface to make it extra smooth to the touch. Without it, the surface is just slightly sticky.

Store it away from direct sunlight, in a breathing cloth bag. Standard procedure πŸ™‚


With Lusty Hot Spring, Toy’sHeart released a noteworthy onahole.

While it features everything Toy’sHeart is still leader in nowadays (material, very few smell, little bottle of quality lube), I’m a little bit sad about the illustration: I was used to seeing a more sexually explicit drawing on the backside.

The outer design is a good baseline, they can make a lot of series with various internal structures while reusing the same base molds, and the processing itself is well done.

On Lusty Hot Spring the insides give a middle intense sensation, it really won’t go easy on you and more than once it took me lots of self-control to keep myself on the edge. The aftermath ? Deep relaxation. Got myself stunned for a few minutes a couple times πŸ˜€

As for the price, it’s not surprising of Toy’sHeart. Good enough.

Note: at the time of writing, Lusty Hot Spring has limited availability
