Hi everyone, this is OnaLab and today I'm covering the NPG Urethral Sex Legend Rin Hachimitsu, an onahole based on the adult star Rin Hachimitsu that adds something I've personally never seen on an onahole before, a fully usable urethral hole alongside the vaginal one.

Initial Impressions

Opening it up, the unboxing is standard for NPG, with a colorful, ornate box covered in tons of hot images of Rin Hachimitsu, the adult star this toy is based on. Inside you get a matching 80ml bottle of lube, a small photo about the size you could keep in your wallet, a bigger poster, and the onahole itself, which comes sealed in a larger resealable NPG bag with an inner plastic wrap underneath that protects the toy. Lifting it out, it's a nice and hefty toy at 870g, which is something I always watch for, since I personally like having more material on an onahole to cut down on feeling your own hand's grip through the toy and to give the texture more room to breathe and shine.

Design

Starting at the entrance, NPG went with subtle puffy innie lips here instead of a loud vagina design, and those innie lips give the entrance a nice gripping feel while really emphasizing the puffiness of the pussy, which to me is the star of this toy. The big feature though, and a first for me personally on an onahole, is the urethral hole, a fully usable sex hole that's substantially tighter and has a more consistent texture, in addition to the complex, highly stimulating vaginal texture. Moving along the body, there's a little belly button on the front, and the whole thing curves a bit to ergonomically give you a nice grip in hand.

Turning it around, the butt of the onahole has enough cheek to give it a cute little crack, which slaps nicely against you during use.

How It Feels

On the OnaLab softness scale where -5 is firmest and +5 is softest, the overall body lands at around +1.2, so slightly on the softer side for TPE, while the inner material is around +2.1, which makes it noticeably softer than the body.

Going in, there's a bit of a gap between the innie lips and the actual holes, since NPG left some room there for you to choose whether you're going into the vaginal hole or the urethral hole. It reminds me of the way Sensbody does their onaholes, where you can see the urethral opening before you get to the vaginal texture instead of going straight into it.

The vaginal texture is highly stimulating, around a +3.8 on the OnaLab stimulation scale where 5 is the most stimulating, which is about what I'd expect from an NPG onahole, since they typically go for big bold fantasy textures that make you cum fast. Heading down the tunnel, it has those classic big swirling nubs with smaller nubs attached to them, before leading into a more mellow, looser area with fewer of the little nubs and more reliance on the big ones, and it finally ends in a massive uterus catch that sucks your tip in at the very end. To me, it's very classic NPG, with a big reliance on heavy stimulation to make an impression.

Switching over to the urethral hole, which is the big headline feature here, it actually reminds me of an even tighter anal hole. The texture is like what you'd find in an anal tunnel, but because of the size and placement it feels noticeably tighter than anal holes with a comparable texture. It's less stimulating than the vaginal side since there's less room for those big bold nubs, landing at around +1.4 on the OnaLab stimulation scale, but it makes up for that in extreme tightness, which feels quite nice.

Going back and forth between the two, the design was actually more practical in use than I'd initially expected. Because of that gap between the innie lips and the holes, it's really easy to switch between the two while going at high speeds, whereas with a more traditional onahole that has an anal and a vaginal hole, you'd have to pull yourself out completely and insert into the other hole. Here you can pull out just until your tip is in that vacuum gap between the lips and the internal holes, and then angle yourself into whichever hole you want, which I found quite intuitive and fun. It is a lube guzzler if you want to go this route though, but I thought it was worth it for the experience.

Verdict

4.7/5 from me. Overall, this is a really fun little onahole with a unique feature I've never seen on any other onahole before, and it feels pretty great. The vaginal tunnel is classic NPG, big and highly stimulating with a massive uterus catch at the end, and the urethral hole gives you a much tighter, more consistent alternative that you can switch into without pulling all the way out. The main thing to keep in mind is lube, since switching between the holes will go through it pretty quickly. At $50 from OtonaJP, it's an easy, fun onahole to recommend, since you're getting two different experiences out of one toy, and if you happen to have a urethra fetish, this toy was made for you. I'd highly recommend it.
