F2S DOUBLE SONIC RED

LELO F2S™ Double Sonic Dual Sonic Masturbator

Slide your member into the soft channel and begin slowly. With every movement, pulses act on both sides, traveling along the member like a wave — and when you change your pace, the device can change with you. You can control everything yourself or let the technology shake up the rhythm a little. The LELO F2S Double Sonic is a dual sonic stimulation masturbator that combines hand movement with sonic waves, adaptive stimulation, and app control.

For whom? If a classic sleeve is no longer enough for you and you want something that not only wraps around the member but works actively with you during movement. The F2S is used solo, where you set the pace yourself, but you can also hand over control to your partner via LoveBridge and see how long you can last before taking it back. If you are looking for a simple model without electronics or an app, choose a classic manual masturbator.

What sets the F2S Double Sonic apart

Here, the movement of the hand is just the beginning. Motors placed on both sides of the channel create waves that meet on the member, while additional modes can deliberately break the regularity or respond to the way you move the device.

• Dual-side sonic stimulation — pulses travel across the entire channel rather than focusing on a single point
• Humanize feature — introduces slight variations in rhythm and power for pulses that don't run in a perfectly programmed loop
• AI mode — the built-in sensor reads your movements and adjusts the stimulation character accordingly
• SmoothRise — power rises and falls smoothly, without abrupt jumps between levels
• LoveBridge — you can hand over control to your partner remotely
• LELO App — gives you access to other ways to use the device and increased control over what happens

Instructions for use

1. Charge the F2S Double Sonic and, if you wish to take advantage of all its capabilities, connect it to the LELO app via Bluetooth.
2. Apply a generous amount of water-based lubricant to the member and inside the channel.
3. Turn on the device and slowly slide your member inside. The sensor will recognize your presence.
4. Start with slow movements. Change the rhythm, intensity, and modes until you find the combination that makes it really difficult to keep your cool.
5. When solo, try the Humanize or AI mode. In a duo, activate LoveBridge and hand over control of what happens to the other person.
6. After use, wash the device thoroughly. Only use water-based lubricants on the silicone surface.
