Seikatsu Shuukan The Animation

Shuntarou is a textbook high school pornography enthusiast. He experiences intense sexual attraction towards his younger sisters, whom he really adores in a manner that is inappropriate for an older brother. Even to the extent of pilfering their undergarments and indulging in it, a behavior that elicits profound contempt from them. His sole desire is to have a compassionate and benevolent elder sister who would be the radical antithesis of his ill-tempered siblings.Following one session involving the genitals of young women, Shuntarou discovers an enigmatic new video game on his computer. Despite his lack of memory of ever downloading it, the term “Older Sister Week-Long Experience” is too enticing to resist. However, despite the game appearing to be inactive, the following day he is reduced to the dimensions of an 11-year-old.Upon being found by his sisters, he promptly reveals himself as Koharu, Shuntarou’s online acquaintance, and the girls immediately get captivated by his charming and naive countenance. Koharu deftly exploits the circumstance and willingly exposes himself to the gentle nurturing of his unaware, now more mature sisters.
