Lelo F1s V2 Waterproof Sucking Mens Masturbator uses breakthrough SenSonic technology alongside traditional vibration motors to create sonic waves that penetrate deep into your cock. This Swedish-engineered sex toy targets nerve endings throughout your entire shaft rather than just surface stimulation, building to more intense orgasms than manual stroking can achieve.
SenSonic waves pulse through your cock while the traditional motor adds familiar vibrations around your head and shaft. The flexible silicone sleeve adapts from 129mm to 150mm internal girth, gripping your cock while both motors work simultaneously. Ten built-in sensors monitor how hard you thrust and how your body responds, feeding data back to the Bluetooth app for customized experiences that evolve with your preferences.
Cruise Control technology prevents power drops when you're close to cumming, maintaining consistent intensity exactly when you need it most. Your breathing gets heavier as the sonic waves build pressure throughout your cock, creating fuller sensations that spread beyond just your head. When you finally cum, the dual stimulation makes your orgasm feel deeper and more complete than typical masturbation sessions.
Charge the F1s V2 fully and download the LELO app before your first session. Apply water-based lube generously to your cock and the silicone sleeve. Insert your head into the opening - the sleeve will grip snugly around your shaft. Start with the lowest SenSonic setting to feel how the waves pulse through your cock differently than regular vibration.
Control intensity through the device buttons or smartphone app while thrusting at whatever pace feels right. The sensors track your movements and arousal patterns, adjusting stimulation automatically. Most guys find the combination of sonic waves and vibration brings them to climax faster than expected - the sensations build progressively until you're cumming harder than usual.
Tech-savvy guys who want data-driven masturbation experiences will love the performance tracking and app connectivity. The size works best for average to larger cocks - smaller guys might find the sleeve too loose for optimal contact. If you get bored with regular masturbators or want something that feels genuinely different from your hand, the SenSonic technology delivers sensations no other sex toy can replicate. Skip this if you prefer simple, non-electronic toys.

While not traditional electrical stimulation, the F1s V2's sonic wave technology creates similar deep-tissue sensations that penetrate beyond surface nerves. This represents the premium end of stimulation devices, offering controlled intensity that builds progressively like e-stim without requiring electrode placement or conductive gel preparation.
The F1s V2 stands apart from rotating or stroking masturbators by using sonic technology rather than mechanical movement. Perfect for guys who want automated stimulation but prefer internal sensations over external stroking motions. The app control and sensor feedback make it our most advanced automatic option.

The texture against my skin different the sonic waves felt compared to any vibrating masturbator I'd tried before. Instead of buzzing against my cock's surface, the F1s V2 created this deep, pulsing pressure that seemed to come from inside my shaft. During my first twenty-minute session, I kept switching between sonic-only mode and the dual stimulation to compare - the combination definitely intensified everything. My breathing got noticeably deeper about ten minutes in as the sensations built up in layers rather than just hitting my head. The Cruise Control really works - when I started thrusting harder as I got close to cumming, the power stayed consistent instead of dropping off like other electronic toys. When I finally came, the orgasm felt fuller and lasted longer than usual. The whole experience ran about twenty-five minutes from start to finish, and checking the app data afterward was genuinely interesting - seeing my arousal patterns mapped out added a surprisingly engaging element to solo play.
Order your Lelo F1s V2 Waterproof Sucking Mens Masturbator from the cockringshop today and experience Swedish-engineered sonic wave technology that delivers sensations no other masturbator can match. Your solo sessions will never feel the same once you discover what dual-motor stimulation with real-time performance tracking can do.
