OTouch Inscup 4 Intelligent Suction & Contraction Masturbator

The INSCUP 4 Gen 2 Suction Tech Premium Male Masturbator is built for those who want a deeper, more responsive experience than a traditional sleeve. Powered by second-generation suction technology, it combines automatic clamping, rhythmic suction and 7 adjustable vibration modes to create a more immersive, glans-focused sensation.

Visually, the INSCUP 4 looks polished, masculine and discreet. Its smooth black silicone-style exterior, metallic silver cap and minimalist OTouch branding make it feel more like premium tech than a standard male sex toy. The design is refined enough for travel and storage, while the magnetic privacy lock helps keep everything discreet between sessions.

Inside, the removable TPE sleeve is soft, textured and designed to wrap the shaft in a more lifelike sensation. The automatic suction and contraction-style grip work together to create a rhythmic pulsing feel, while manual and automatic control options let you adjust pressure and pace to suit your mood.

The INSCUP 4 male masturbator also stands out for its practical hygiene design. The sleeve can be removed for deeper cleaning, helping keep your toy fresher, easier to maintain and ready for your next session. With a usage time of more than 60 minutes on a full charge and a quiet operating level under 60 dB, this automatic suction masturbator is made for private, powerful pleasure without unnecessary fuss.
