We've been looking for a versatile toy we can use for double penetration and pegging, and this it the BEST hollow strap on style dildo either of us have ever seen! The silicone is silky silky smooth, and at first I was unsure about how I'd fit in it, since I don't think most men would be able to fit inside the hollow shaft. Then I looked at the box (I'm one of those "Who needs directions!" kinda people). You actually place your penis and balls in the hole located under the shaft (my wife isshaking her head at me, apparently it is very clear on the site that that is what you do). I had NO issue fitting into the hole, and I found that it did double duty of acting like a cock ring (though not a tight one, and you could wear a cockring with this if you wanted too). I wasn't super hard when I first put it on, since my wife ambushed me on my way in the door, so I started by using the silicone shaft to fuck her pussy. Her moaning got me really hard pretty fast, so I added a little extra lube to the shaft and used it in her ass while I fucked her. She's NEVER made those noises before! The cup shape of the whole device means that you can really thrust, and it moved really well with my motions for a slick pounding. Sometimes dual penetration cockrings have a tendency to stay put once theyve been inserted, so the ring slides on your cock and doesn't really thrust into your partner, but this totally worked just like it was supposed to. We haven't used it for pegging, but since the whole piece is silicone I'm not concerned about being able to clean it really well. We also both appreciated the two sets of harness bands (which are RIDICULOUSLY COMFORTABLE... anyone whose worn a harness know s that isn't usually the case), since one fits me and one fits her. She's a big fan of being able to toss the whole thing in the wash after and having it clean up in the laundry. You cannot do that with a leather/faux leather harness. This is hands down the best hollow strap on/double penetration/pegging/cockring/sex toy that either of us have ever used! I know its expensive, but it is SO worth it!
