Inscup 4 Gen 2 Thrusting and Contraction Masturbator

Inscup 4 Gen 2 Thrusting and Contraction Masturbator is an automatic stroker that combines suction with compression waves and hands-free thrusting. It delivers realistic sensations without manual effort, letting you focus on building intensity through four distinct pleasure modes.

What it is

Inscup 4 Gen 2 Thrusting and Contraction Masturbator is a second-generation automatic stroker engineered to replicate realistic intercourse sensations through synchronized suction and compression. The device pulls you inward with variable suction while 360-degree compression waves massage along your length, all whilst an integral thrusting mechanism adds continuous motion. Unlike basic textured strokers, which rely on texture alone, this combines multiple forms of stimulation in one coordinated sequence.

The silicone body houses a removable TPE sleeve that delivers the sensation, whilst the ABS plastic outer shell contains all the mechanics. Four separate pleasure modes let you switch between patterns automatically, or you can take direct control of compression intensity yourself. Battery life exceeds 60 minutes at full power, making extended sessions realistic without mid-session recharging.

What stands out

• Dual-action stimulation: Suction and compression work together rather than separately, creating rhythmic waves that build and release like natural contractions.
• Automatic thrusting: The built-in mechanism moves you through the sleeve continuously, eliminating the need for manual stroking throughout a session.
• Four distinct modes: Regular, automatic, and burst settings plus manual clamping give you real variety without needing multiple devices.
• Touch-screen controls: A simple interface lets you change modes or intensity mid-session without interruption or fumbling.
• Removable sleeve: The TPE interior slides out for thorough cleaning and drying, making hygiene straightforward and maintenance quick.

Using a masturbators and stroker properly

Start by charging the device fully via the USB port before your first session; a complete charge takes approximately two hours. Apply water-based lubricant generously to the inner sleeve opening and to your penis, as this reduces friction and improves the sensation of the suction and compression. Insert yourself slowly into the sleeve, allowing it to seat properly around your shaft before activating the device.

Begin with the regular mode to familiarise yourself with how the suction and compression feel together, then explore burst or automatic modes once you understand the rhythm. You can pause at any moment by pressing the power button, and manual clamping lets you adjust compression intensity without stopping the thrusting action. After every session, remove the TPE sleeve, rinse it thoroughly under warm water with mild soap, and allow it to air-dry completely before reassembling. Store in a cool, dry place away from direct sunlight; unlike sex dolls, which require larger storage space, this device fits discreetly on a shelf or in a drawer thanks to its compact footprint.

Is this the one for you?

Care and storage

Rinse the removable TPE sleeve under warm running water immediately after use, using mild unscented soap to clean both the interior and exterior thoroughly. Pat dry with a soft cloth, then allow it to air-dry completely before reassembling or storing. Wipe the silicone body and plastic housing with a damp cloth, then dry with a soft towel. Store in a cool, dry cupboard away from direct sunlight and extreme temperatures, using the included magnetic privacy lock to prevent accidental activation. Keep the charging cable in a safe place to avoid damage.

What to expect

Most users notice the difference between this and basic strokers on the very first use. The combination of suction pulling inward whilst compression waves massage outward creates a sensation that manual strokers cannot replicate. Expect a learning curve of one or two sessions as you discover which of the four modes matches your preference; many people find burst mode builds intensity most effectively.

First-time users often underestimate how much lubricant makes a difference to comfort and sensation. The sleeve works best when well-lubricated; too little lubricant creates uncomfortable drag, whilst adequate lubrication allows the suction and compression to work smoothly. The thrusting mechanism is consistent and reliable, never stuttering or losing rhythm during a session.

Battery life holds steady at over 60 minutes even after extended ownership; the device does not lose power rapidly as some rechargeable toys do. Cleaning the TPE sleeve takes less than three minutes, and it dries quickly if you hang it vertically on a hook or stand it upright on a towel. Storage in a cool cupboard keeps the materials from degrading, and the magnetic lock means you do not risk accidental activation in a bag or drawer.

People who enjoy hands-free, automated sensation tend to keep using this long-term, whereas those who strongly prefer direct manual control sometimes find the automatic modes less satisfying than a simple hand-stroking toy. The noise level is moderate—audible in a quiet room but not loud enough to cause concern in most living situations.
