Innocent Younger Sister

Like it’s sister product Sexy Elder Sister, Innocent Younger Sister is a redesign of one of ToysHeart’s “classics”.


Aesthetics. Did the “moe / kawaii” characteristics evolve over time ? Because yeah, this onahole kinda deserved a refreshed packaging design:


D-Don’t you think the new design hereafter went a bit more “otokonoko” ? I mean, she kinda looks like Chico gone older and deeper into MtF… Yeah Chico, ya know.. Bo ku  no Pi co.. I’m adding spaces on purpose so Google doesn’t mis-index it and deceives people.. Don’t look it up if you don’t know this reference, I’m assuming you’re not completely perverted.. yet ( ͡° ͜ʖ ͡°)


The fundamentals of the packaging didn’t change: pink shorts, white I-don’t-even-know-how-this-is-called-but-it’s-holding-the-boobs, light head tilt, naive face, and if I had to give her words:

Hey onii-chan, look what I bought today at the store ! Does it look cute to you ? You like it ? uuh.. are you okay, you’re breathing heavily all of a sudden..


.. nii, my new panties.. this is kinda embarrassing.. Please be gentle with me..


Moving on. Inside the box, you’ll find the usual plastic tray containing the onahole and a small sample of Moisty™ lube, which should give you enough for 2 uses or so.


14.3cm in size, 374g weight, 11cm tunnel size, using ToysHeart’s mindblowing SafeSkin material that is stretchy, has as good as no smell, feels really nice to the touch and could be licked safely. ToysHeart still as of today on first rank in TPE material quality, and as good as no defect detected on mine (very light wrinkles).


Smell, durability, entrance usability… I have not a single complaint so far. It’s really quality stuff and I’m sorry to say this for, like, almost all ToysHeart products I reviewed lately, but it’s true. Even more since this onahole concept is older, just later in ToysHeart’s timeline they released Seventeen Evolution. Which means Innocent Younger Sister dates back in the very early days of Onahole Review, for fuck’s sake ! Of course at some point they needed to update the packaging to make it clear the onahole is still around, improved all that time !


If you happen to buy both sisters, learn how to differentiate them after the entrance shape. Because on the outside, shape, color, size and weight, you won’t be able to tell which one is from each other ! The entrance of Innocent Younger Sister also has a spiral-like pattern, but with bumps. The tunnel is pretty simple, with light curve, little bumps, some ribby structure, ending with a bumpy cervix for the joy of deep penetration. One may think it’s an “undeveloped” version of Sexy Elder Sister, however it has distinct stimulation and twists. I like the Younger a little bit more because of the more snug feeling: more surface contact on the shaft. Being a bit more airtight at the tunnel, it achieves a slightly better suction effect. Finally, less deep grooves in the tunnel mean easier cleaning 🙂

ToysHeart rates it as “loose” type with below-medium stimulation, and I think I can agree with that. Or maybe actually medium tightness for westerners. But unlike Sexy Elder Sister, the included Moisty lube did a good job with that one !

After the business, the cleaning. Single layer = no worries turning it inside-out to clean all the surface, I had no issue flushing away all the stuff and the onahole dries quite fast. While it’s nice to the touch as-is, you can rub some corn starch powder on it’s external surface for extra smooth feeling.

And about the price, I know ToysHeart products usually come with a little price extra but the 30-35 $ range at retailers seems very honest to me. There are cheaper onaholes, but they are smaller or way less good. No really, you get your masturbation fun for the price and with the excellent durability of the material it will last you for months (even years ?). A cute younger sister !

Innocent Younger Sister is the exact proof that no matter if it’s a redesign, ToysHeart still outperforms any maker on materials. It totally deserved a new cover girl, and it will milk you out just perfectly if you’re a beginner. Good job ! (imouto wins !)

  1. Just to confirm is the top pic the original box art? And then the bottom one is the new one correct? I’m 100% sure if its the bottom one its not going to make it past Canada’s customs.

  2. Yo Akai,

    I made the mistake of buying a Boku Ona 2 ona.
    I mean its ok and all, but I have this thing with my penis that makes my tip really sensitive, and the entrance to the second section makes me a little uncomfortable.
    Is there an onahole with a tight entrance but the rest just stimulates the sides? (still tight but not stimulating the tip)


      1. Just had another round and I realized I was using it wrong, I was pushing my dick through the side of the onahole lol. But damn these onaholes make me go quick.

        Are there any cheap onaholes that are really durable? (Like bungee etc)
