I have been looking to get a male masturbator for a while, so when the opportunity to review the Arianna came up, I was very excited.
Arianna is a simple toy but offers some amazing sensations. Use is quite straight forward- simply lube (with either silicone or water-based lube) the interior of either the anal or vaginal openings and thrust away. You can use your hands to thrust the toy up and down or place it between a mattress and box-spring (or couch cushion) for some hands-free action.
Arianna will have you groaning with pleasure in no time!

Arianna is made from TPR which is a very realistic feeling material. There is quite a bit of stretch in this toy but it makes for a wonderful sensation as it tightly grips the penis when inserted. Arianna had a bit of a synthetic sweet scent when I opened the packaging but that went away after the first wash.
TPR is a porous material, so condom use is a must if sharing. Moreover, it is NOT safe to use oil-based lube with this toy. Use either water-based or silicone lubricant.

Arianna is designed with both a vaginal and anal opening. The vaginal lips and opening are beautifully shaped and quite realistic looking. In terms of the interiors, the anal canal is quite short but meets up with the vaginal canal. The joined canal ends at an opening on the opposite side of the toy.
The interior texture at the vaginal and anal opening is smooth and soft and then transitions to an area of textured bumps and ridges about two inches from the opening. These bumps and ridges continue to the end of the toy and offer very pleasurable but subtle stimulation.
The toy is 8 inches long so it should work well for most men but could accommodate even the best endowed among us since it is open on both sides. The vaginal opening is 1/3 inch in diameter which is quite tight but since the TPR is quite stretchy it accommodates even a larger size without being too loose for the smaller of us. The anal opening does not differ much from the vaginal in sensation but it is a nice feature of the toy nonetheless.
Arianna is a pretty toy but is by no means discrete. If anyone saw her they would know immediately what she is for. Luckily, however, the toy is not so large that it is un-hideable. Push the box she came in between a stack of clothes in your dresser and no one will find her except you.

In order to clean this toy I pushed it inside out and washed the interior with warm water and some soap. This did the job nicely but turning it inside out was a bit harder than expected due to the anal opening which made this quite complicated. If you are looking for something very easy to clean then this might not be a great option.
After a few washes I have noticed that the TPR material is getting a tacky/sticky feeling to it. I have heard that dusting with corn starch is a good way to avoid this but I have not yet attempted that.
TPR is a porous material but it can't be sterilized by boiling so condom use is a must if you are sharing this toy with a partner.
And to repeat this again, oil based lubes CANNOT be used with this toy. Stick to silicone or water-based.
In terms of packaging, Arianna falls a bit short. The toy came in very non-discreet box with a scantily clad girl on one side and a few pictures of the toy on the other. I store the toy in the box but this is not ideal as it is not very discreet.
