RPP #215: 4D Automatic Stroker Vibrating Male Masturbator Cup (Bestvibe)

If you are a regular reader of the blog, you know I am always looking for ways to pleasure myself with the least possible effort – you know, because of my chronic pain issues. When the friends at Bestvibe contacted me and offered a vibrating, automatic stroker for me to review, I said YES without hesitation. I have a strange relationship with electronic toys, but hey, any toy promising orgasms with minimum physical movement is worth of my attention!

Is the 4D Automatic Stroker Vibrating Male Masturbator Cup (The Cup from now on) the toy for me to use when my back is messed up? The only way to find out is testing it, so LETS GO TO THE REVIEW!

First Impressions

When I got this toy, I was intrigued by it. Unlike other vibrating sleeves I have tested in the past, the Cup has a heavily textured interior with structures seeming to simulate a mouth and the sensations of a blowjob. The package is simple and straight to the point – the toy, a charging cable, and an instruction manual. The Cup itself has only three controls: a power button, a mode cycling button, and a “memory lock” button. It charges with a proprietary “stabbing” USB cable, so keep that charging cable safe!

The orifice is non descriptive (it does not look like any human body part), but the interior gives you that “mouth texture” vibe. The Cup has a plastic body slightly textured for better grip and a silicone handle that is easy to keep hold of it. The tip of the handle seems to have two “bubbles” that according to the instructions, are a “dynamic response interaction” (whatever that means).

Physically, the Cup is a relatively big toy. The whole toy measures around 9 inches tall by 4 inches wide in its widest part. Like most electronic toys, it comes partially charged, so I turned it on to check out the functions.

Big, but light!

The Cup has 12 different patterns easily cycled by pressing the middle button on the handle. The memory button simply keeps the current pattern fixed allowing you to relax and enjoy the sensations. So far, so good…

Unlike other vibrating toys, the sleeve of the Cup is removable and heavily textured. Having a removable sleeve means it is going to be easy to clean – a BIG factor when I am dealing with electronic toys. The sleeve by itself is interesting. The opening is wide enough for most guys and allows to put your little friend inside even when soft.

The texture is a series of wavy flaps running parallel to the penis with an array of bumps at the very end of the tunnel. There is a mound with flaps to stimulate your frenulum, telling me this sleeve can be a tough one if needed. Upon further inspection, I realized this mound is right above the vibrator, so yes, this will be interesting!

I told you!

The sleeve is around 4 inches deep, so most guys will go in and receive stimulation in most of their little friends. The material is soft, so with the vibrations the Cup promises long and intense sessions.

The next step was a given, so I plugged in the Cup and waited until sleep time to test this one…


As I said before, I have a difficult relationship with electronic toys. I tend to enjoy the sensations, but they keep me on the edge and do not allow me to finish… or are too intense and make me cum before I can really process the sensations. The Cup was different…

Although the Cup has the usual restrictions of vibrating toys (you know, limited amount of time to protect motors from overheating), it allowed me to finish every time I used it. Why? Well, the Cup does not only vibrates, but the textured sleeve allows you to use it as a typical stroker. Basically, you can use the Cup as a stationary vibrator, a manual stroker, or as a manual vibrating stroker – and each mode gives you totally different sensations!

I placed the Cup between the legs of one of my dolls and used it as a stationary vibrator. Just placing my little friend inside the Cup and cycling through the patterns until finding one which I liked for the session and then relaxing my body while holding my “sex robot” allowed me to have interesting sessions. I kind of melted just relaxing and allowing the toy to massage my little friend for a couple of minutes was enough for me to get diamond cutting erections – something that is becoming more and more difficult as I reach the big five-o…

When I shut off the vibrator to avoid over heating, I would start short movements inside the sleeve… Oh. My. Good! The texture hit me with everything it had – and it was plenty! As expected, the mound stimulated my frenulum, giving intense pleasure while the other wavy structures surrounding my penis just caressed and massaged the rest of it. Hitting the sleeve as deeply as it allowed me to go, I hit the bumps with the glans of my penis and after a couple of strokes I had to stop moving to avoid cumming before I wanted to do it.

Of course, I wanted to experience the sleeve with the vibrations, so as soon I felt the toy was ready, I turned the vibrations back. Moving slowly inside the toy, orgasm was inevitable after a couple of minutes.

One of the things that helped the Cup taking me over the edge was the dynamic response bulb. Remember the bubbles I mentioned earlier? When you press them, the Cup increases the strength of the vibrations while you keep it pressed. It is like one of those “turbo” modes in some vibrators. Whenever the Cup had me on the edge, I pressed the bulb and the increased vibrations (with a couple of strokes inside the sleeve) worked with the textures and took me over, making me cum – sometimes so strongly that all my muscles tensed.

As said before, the Cup gave me completely different experiences depending the way I used it. With just the vibrations on, the Cup is perfect for long sessions by just inserting the penis and allowing the patterns to engulf you. Orgasms build up slowly, but when they hit, they hit hard. With the vibrations and just the slightest movements, you can have shorter sessions, but the orgasm build up is quicker and the orgasms are earth-shaking. Used only as a stroker – no vibrations – , the orgasm build up is intense, but it will depend on the stroking speed. With you on total control, the Cup will take you to orgasm as quickly as you desire.

Cleaning the Cup is extremely easy. You just remove the sleeve and clean with running water. Turning the sleeve inside out is easy to do for better cleaning. You can either pat dry with a towel or allow it to air dry.


The 4D Automatic Stroker Vibrating Male Masturbating Cup (the Cup) is an interesting and versatile sex toy. It can provide totally different experiences with its 12 vibrating modes or by using it as a basic stroker. If you are looking for an unique toy that can provide intense orgasms, check out this toy from Bestvibe.
