The top-tier poster, Mr. I, who has gone to great lengths of evil, finally begins to move towards his long-desired "Harem Plan"! Blindfolding himself, he lies motionless on the bed like a massive tuna meat, not even twitching. On the fat of this giant fish, two young girls, like a demonic ritual, ceaselessly caress with their lips, tongues, hands, and wombs. The ultimate lazy play. Before reaching this point, there are numerous chaotic events, like overturning a toy box, including a man being used as a toilet and deceitful plays. This time, the chosen sacrifices are Ayaka, an unconscious system nympho little devil who hides a devilish sensitivity behind her clear appearance, and Kotori, a clever system big-breasted loli who would deceive even friends and lick the assholes of the obese for her purpose. These two, boasting natural sexual skills even among recent victims, relentlessly torment just an ordinary obese person!
