The BIGBANG Masturbation Training Cup Series showcases every thrust in full detail through its transparent body visual pleasure that hits straight between your legs. Paired with exquisite cosmic gradient illustrations, the designs of Planet, Star, Galaxy, and Black Hole wrap your desire in a vast universe of lust. The see-through structure makes every stroke vividly visible, igniting both visual and physical arousal from the very first glance.
Peel off the AIRHOLE sticker on top and lightly touch the opening with your fingertip to control the suction precisely. The moment you cover the hole, the interior grips you with a living, explosive sucking force, tightly swallowing every inch. The airflow rhythm blends with the friction of the inner textures, giving you deep suction, tight wrapping, and that irresistible “locked-in, can’t pull out” intensity.
Planet and Star are designed for beginners, offering soft enveloping stimulation with bouncy elasticity. Inside are unique particles, bumps, and spiral textures that gently yet accurately tease every sensitive spot.
Galaxy and Black Hole are advanced levels tighter, more complex, and made for deep training thrills. Each of the four channels has a completely different internal design, making every penetration feel like exploring an unknown universe where every centimeter hides a new surprise.
Galaxy and Black Hole come with Red Soft Beads, unlocking an entirely new cosmic-level sensation. These ultra-soft beads slide, scrape, and press along the inner wall, repeatedly hitting the sensitive rim of the glans. You’ll feel the beads moving like living creatures inside, colliding and rubbing against you, sending electric sparks of pleasure that spiral out of control like being pulled into a black hole of climax.
Crafted with premium elasticity-enhancing material, the cups are soft, silky, and resilient stretch or bend them however you like, and they instantly return to shape. The interior is smooth and lubricated-feeling, creating a moist, swallowing sensation that keeps every thrust unbelievably fluid. Even after repeated use, it stays looking and feeling like new. With the transparent body showing you being fully enveloped every time, the sight alone reignites raw, uncontrollable desire as intense as the very first time. |
