One day, "Karin," who ignited the flames of jealousy at Sanada returning home with the scent of a woman, had her love and lust run wild... The jealous female cat is in heat 24 hours a day! She squeezes out her owner's semen until her libido is exhausted. "I love you so much, please make me carry your child" Even the owner's reason collapses with the relentless mating of the tireless female cat!!
