Mama Katsu: Midareru Mama-tachi no Himitsu, Episode 4

Imamoto Yoshiya is a man with great talent in awakening the maternal instincts of women and, therefore, does not have a particularly difficult time getting them. Spoiled as a child by his older sister Kyoko, he developed complexes for women similar to her and has continued to improve his sexual techniques over the years. His prey patterns are usually middle-aged ladies. Since he can no longer resist the beauty of Kyoko, he now tries to conquer her as well. He wants to take advantage of the opportunity that arises when her husband goes on a business trip. ママ喝っ, Mama Katsu, 妈妈活, 마마 카츠
