When she wakes up again, she finds herself deeply penetrated by the man's penis. The man, laughing at Misaki's resistance, ejaculates inside her without hesitation. On the day of ovulation, rape... The despair that enveloped her did not end that day! In the madness of being repeatedly raped until impregnated by a pervert whose purpose was not pleasure but insemination, the insanity of impregnation rape!
