INSCUP 4 is built for users who want more than basic vibration — combining controlled suction with adjustable manual clamping so you can fine-tune both pressure and fit during use. The tighter, more focused sensation comes from OTOUCH's second-generation suction technology, which works with the clamping system to create a deeper, more natural rhythm that feels noticeably more immersive than single-function devices.
Two controls. One experience. 4 suction modes handle the rhythm. Manual clamping adjustment handles the fit. Run them together or independently — the combination gives you a level of personalization most masturbators don't offer.
7 Vibration Modes Layer vibration on top of suction and clamping, or use it on its own. Seven patterns mean you're not locked into one setting.
Built for Repeated Use The smooth silicone exterior stays comfortable during extended sessions. The removable TPE inner sleeve pulls out cleanly for rinsing — no awkward cleaning workarounds.
Discreet by Design The magnetic privacy lock with key access means the device stays sealed until you open it. Ideal for shared living spaces or travel.
Care Instructions The main unit is not waterproof — do not rinse or submerge the outer body. Remove the TPE inner sleeve, rinse thoroughly, and allow all parts to dry completely before reassembly. Use water-based lubricant only.
1) How to choose the right toy
Start with your goal: gentle relaxation, stronger intensity, targeted stimulation, or hands-free use.
Beginner-friendly picks: smaller/medium size, multiple intensity levels, and a simple shape (easy to control).
Couples: look for quiet, remote/app control (optional), and designs that don’t get in the way.
2) Materials that feel better (and are safer)
- Body-safe silicone (smooth, soft, easy to clean) is the most popular.
- Avoid mystery materials. If you’re sensitive, choose non-porous materials (silicone, stainless steel, glass) and always clean before/after use.
- If you have allergies/skin sensitivity, patch-test by touching the material to your skin first.
3) Power, noise, and waterproofing
- USB rechargeable = convenient and usually stronger than battery-only.
- If you need privacy, choose low-noise models and check reviews/specs.
- Water resistance vs waterproof: waterproof is easier for cleaning and shower use but always follow the rating (e.g., IPX6 is strong water resistance, not full submersion).
4) Lube compatibility (important!)
- Water-based lube works with almost everything and is the safest choice for silicone toys.
- Silicone-based lube can damage some silicone toys over time (unless the brand says it’s compatible).
- Use more lube if there’s any friction—comfort first.
5) Cleaning, storage, and sharing
- Wash before and after: warm water + mild soap or toy cleaner, then dry fully.
- Don’t share without protection: if sharing, use a fresh condom on the toy and change it between partners/uses.
- Store in a clean pouch/box, away from dust and away from other toys (some materials can react when touching).
6) Safety basics
- Start on low intensity, go slow, and stop if there’s pain, numbness, or irritation.
- For any toy designed for deeper insertion, make sure it has a wide/flared base (this is a key safety feature).
- If you’re pregnant, have a medical condition, or experience persistent pain, check with a clinician.

What Is the Second-Generation Suction Technology?
At OTOUCH, "second-generation suction" is not about simply increasing suction power—it represents a fundamental rethinking of how suction should feel.
From Passive Suction to Active Clamping
Traditional suction-based male masturbators rely on negative pressure within a sealed chamber to create sensation. However, under vacuum, the soft inner sleeve tends to expand—particularly near the base—making it difficult to maintain a close, consistent fit around highly sensitive areas such as the glans and coronal ridge.
The result is a common limitation: strong pulling force, but insufficient precision and tightness where stimulation matters most.
OTOUCH addresses this with a redesigned system that combines suction with an active airbag compression structure. As suction is applied, the integrated airbag contracts in sync, exerting controlled inward pressure on the inner sleeve. This creates a dynamic tightening effect, especially around key sensitive zones, ensuring a more enveloping and responsive fit.
Key Advantages
1. More Natural Pressure Distribution
Instead of concentrating stimulation in a single direction, the coordinated action of suction and compression distributes pressure more evenly. This produces a sensation that more closely mimics natural physiological contact.
2. Synchronized Depth and Tightness
Suction depth and contraction intensity are directly linked—the deeper the suction, the tighter the fit. This clear feedback relationship enhances user perception, allowing for a more engaging and interactive experience.
3. Greater Stability and Comfort
By balancing suction with controlled compression, the system avoids the abruptness and fatigue often caused by excessive suction alone. The result is smoother, more sustainable stimulation.
A More Advanced Sensory Experience
The true value of second-generation suction lies in its ability to deliver layered, adaptive, and realistic stimulation. Rather than relying on sheer intensity, it creates a nuanced experience that remains comfortable and satisfying over extended use.
