## Emma's take

Real-feel FLEXSKIN meets eight vibration modes for both partners.

I've been curious about this one since it landed — the FLEXSKIN silicone feels genuinely lifelike in a way that surprised me. Eight vibration modes with a boost function mean both partners feel the buzz, and the wireless remote lets you hand over control or keep it yourself. The 2+ inch length gain is confidence-building without being overwhelming, and that real-feel texture makes the difference. Perfect if you want to explore size play with serious attention to sensation for everyone involved.

## Frequently asked questions

## How much length and girth does this add?

The Model F adds 2+ inches of length and moderate girth enhancement. The internal sleeve accommodates most sizes comfortably while providing noticeable fullness for your partner.

## Do both partners feel the vibrations?

Yes — the vibrations travel through the FLEXSKIN material so both the wearer and receiver feel the sensation. The boost function intensifies this for peak moments.

## What's the best way to clean the FLEXSKIN material?

Use antibacterial toy cleaner and warm water. The FLEXSKIN is fully waterproof, so you can rinse thoroughly. Always dry completely before storing.

## How does the wireless remote work?

The waterproof remote controls all 8 vibration modes plus the boost function. It's rechargeable via USB and maintains connection during use. Range is good for bedroom play.

## What lubricant should I use with this?

Water-based lubricant only. Silicone-based lubes can break down the FLEXSKIN material over time. Apply generously inside the sleeve and on your partner for best comfort.
