[490] Sensory Deprivation Portal Ring (voiceroid) [Complete]

A determined yukari yuzuki confronts the relentless 'Portal Ring O2' that forces her into a sensory‑deprivation loop, counting each climax as the device toggles between active and off states. The stark black‑and‑white panels track her escalating count from a solitary attempt to a staggering 100, showcasing intense autofellatio, squirting, and the raw emotionless sex that defines the futanari experience. With each surge the narrative builds a tense, repetitive rhythm that culminates in a final, overwhelming climax, leaving the viewer immersed in the stark, repetitive world of the sensory deprivation portal.
