How to use a masturbators and stroker

Begin by fully charging the device using the included USB cable. Apply generous water-based lubricant to your penis and inside the TPE sleeve opening. Insert your penis into the opening to your preferred depth. Press the screen touch button to activate suction mode, starting with lower intensity to acclimate to the sensation. Use manual clamping control to adjust compression tightness around your shaft. Press the button again to activate vibration modes and experiment with different combinations. The automatic thrusting function engages simultaneously with suction for complete stimulation. Modulate between high and low intensity modes throughout your session to build arousal gradually.

For enhanced sensation, combine multiple modes simultaneously—pairing burst suction with continuous vibration creates intense glans stimulation. Manually adjust clamping pressure to vary sensation intensity and prolong arousal. The magnetic sleeve design enables quick removal for position changes or to intensify sensation by reducing opening size. Experiment with different lubricant viscosities; thicker lubes increase friction while thinner formulas provide smoother gliding. For extended sessions, cycle through different mode combinations to discover what works best for your body.

After each use, remove the TPE inner sleeve by releasing the magnetic fixation. Rinse both the sleeve and silicone exterior thoroughly with lukewarm water and toy cleaner. Allow all components to air dry completely before reassembling and storing in the included protective pouch. Use only water-based lubricants to prevent material degradation. Keep the device away from extreme temperatures and direct sunlight. Store in a cool, dry location using the privacy lock for secure, discreet keeping.

Mistress Athena's training notes

By Mistress Athena — professional dominant and kink educator, sole instructor behind BDSM Australia's library of training videos. Read her full bio →

I've incorporated the Shots Toys Inscup 4 Gen 2 Thrusting and Contraction Stroker into my training protocols with exceptional results. The suction technology allows me to control my submissives' pleasure with precision, denying or granting release through mode manipulation. Observing how their bodies respond to the automatic thrusting reveals genuine arousal levels—the involuntary muscle contractions make it impossible to fake compliance during training sessions. Manual clamping control intensifies sensation right before I pull away, teaching patience and obedience through controlled frustration.

The magnetic sleeve design fascinates me because I can remove it mid-session, forcing my submissives to experience heightened sensitivity when reinserted. Combining burst mode with maximum vibration creates overwhelming sensations that break through mental resistance. I watch their breathing patterns change, their legs tremble, and their involuntary responses reveal the depth of their submission. The privacy lock feature reinforces my complete control—only I hold the key, and my submissives know their pleasure exists entirely at my discretion.

The realistic vaginal opening sleeve enhances the psychological aspect of training because my submissives imagine they're pleasing me while I orchestrate every sensation. I've used this stroker to condition reflexive responses, rewarding obedience with specific mode combinations they've learned to crave. Extended battery life allows marathon training sessions where I systematically build and destroy arousal multiple times, teaching my submissives that climax exists only when I permit it.

Advanced techniques leverage this device's unique capabilities for psychological domination. Starting with basic suction modes establishes baseline sensitivity before I gradually introduce vibration and thrusting to overwhelm their senses and increase suggestibility. Manual clamping control serves as a punishment tool—tightening the grip suddenly creates shock sensations that remind them who controls their pleasure. Blindfolded edge training cycles through all four suction modes in rapid succession, bringing my submissives to the brink repeatedly before locking the device in low-intensity mode, denying climax for extended periods.
