The Nexus Maximus is a silicone masterpiece, the largest of the Nexus double-dildo line. While you can contrive a way to use these without a harness, the Nexi were not designed as "strapless strap-ons,” instead they are among the ultimate harness dildos.

Why would you want to mess with a harness for the Nexus when you can use dildos like the Feeldoe and Share without one? Stability and security - once you're all buckled up with your Nexus you don't have to worry about Kegels to hold on to the giver's end or keeping your butt relaxed if you're receiving anally - both partners can lose themselves in the moment without the risk of the giver's end coming out.

The Nexus Maximus is about the least realistic of the two-person doubles. The "getter's" end (end that points out of the harness) is smooth, with a slight curve up and a bump at the head for added stimulation. Simple, but it feels good and doesn't have any issues to come up against during hard, passionate lovemaking. It slides in easily, and we never had a problem with it coming out due to the length and the slight head that allows you to get a feeling of where the end is.

The "giver's" end has a few tricks up its sleeve, starting with the curve that slides easily into the vagina and gives internal stimulation to the giver. It's very comfortable, and gives G-spot stimulation. On the central bulge there's a clit ridge that does a good job of stimulating the giver's clitoris and labia, especially when the included silver bullet vibe is inserted in its slot (right next to the clit ridge). The vibrations are not particularly strong for the getter, but they do a good job on the giver's side (and the resulting orgasmic frenzy gives the getter plenty of stimulation). Unfortunately there isn't a corresponding clit ridge on the getter's side (while it wouldn't work for harness use, it would be great when the Maximus is used by hand). While some people have reported success with a guy holding the giver's end anally for dual penetration, I wasn't able to do this with the Maximus – it's just too big to control without a harness.

The basic design is pretty good, but the silicone density makes it fantastic (Vixen Creations uses the same silicone across the Nexus line, so you can enjoy it in a smaller size if you want). It's wonderfully soft and feels great when I clench my anus down on it while the Maximus is in me. The first time I held the Maximus I was a bit concerned that it would be too soft, possibly needing several hands to guide it in and keep it on track for anal use. Not so - once it was put in a harness and strapped on it ceased to be floppy, requiring only two fingers to aim the head at my rosebud as a long, slow thrust drove it home. In fact, the consensus here is that the Nexus is better in a harness than many single-ended dildos, as the giver's end adds stability, control, and a "connection" (both physical and psychological) that a single-ended dildo lacks, even when it's in a harness. Once inside, the getter's end did a great job of stimulating me anally, and the soft silicone flexed to both follow my internal curves and J's movements. There were no problems with either of us having trouble in places where our personal geometry differed from the design of the Maximus, something that can be a problem with stiffer toys.

The surface holds lube well (also hair and dust, unfortunately), and the central bulge is big enough to where you won't have a problem with contaminated lube running onto the other person's side. While you can potentially use a condom on the getter's side, it's probably easier to just wash and boil (or bleach) if you're using it for multiple partners (there's no easy way I could find to get a condom on the giver's side, since it would need to go over the central bulge and clit ridge).

The biggest problem that I had is storage. The included plastic sleeve is 15 inches long and 3.5" in diameter, which can be a bit much for a smaller toybox. The other thing that needs consideration is finding a compatible harness. My Aslan Wonder Woman worked perfectly, but if you need to get a new harness look for something with a hole all the way through that rides low and allows you to put the central bulge up against the giver so the clit ridge can work its magic.
