At 10 AM, Yui Amanatsu checks in and exchanges a kiss in front of the door. She's told she won't be allowed to leave the room until she exceeds her limits, and is taken straight to the bed. During an oil massage, fingering makes her whole body burn, and after she squirts heavily, she's brought to orgasm repeatedly with intense thrusting, leaving her completely drained. At 1 PM, after ejaculation, she's carried to another room, but this time even more intense fingering makes her whole body convulse. Even when she says "I can't take it anymore!" the insertion into her pussy doesn't stop, and her legs become so shaky she can't stand on her own. At 3 PM, even in the shower, the stimulation to her pussy doesn't stop, making her scream, and back in the room, her sensitive clit is relentlessly attacked with a vibrator.
