Onii-chan, Asa made Zutto Gyutte Shite! – Episode 1 (RAW)

In the Onami family, big brother lives with his four cute sisters: Sora, Akane, Kohaku, and Sumi. A severe childhood asthma led to the habit of sleeping beside one sister each night for comfort. One day, their scientist parents order an experiment—daily pre-bed hugs to improve immunity through affection. The rules are clear: hug a sister every day, for at least 10 seconds, sniff properly, restart if separated, and do it with genuine love. The sisters enthusiastically frame these "Onami Family Hug Rules" in the living room. Hesitant at first, brother begins practice with Sora, the eldest. As she gently leans her soft, warm body against him, the hug lasts longer than planned. Her scent, closeness, and trusting weight make his heart race unexpectedly. What started as a medical routine stirs forbidden excitement and deeper bonds. With more sisters waiting their turn, these nightly sessions promise escalating intimacy, playful teasing, and emotional growth under the guise of "health benefits." This first installment focuses on Sora's affectionate, slightly bold personality, setting the stage for a series of loving, hug-filled nights that blur sibling lines.
