For one month, Mana Sakura lives under special conditions involving strict masturbation prohibition and constant orgasm denial through handjob. Throughout her daily routine—between work and gravure shoots—she is repeatedly brought to the brink of climax, only to be stopped just before orgasm. In this extreme state, her arousal builds to the point where even the slightest touch of the penis to her vagina causes her body to tremble uncontrollably. After finally being allowed penetration and reaching climax, she experiences non-stop orgasms with ten dicks, culminating in an overwhelming, massive climax.
