[GSUS] Oshi No Ko BEHIND THE STAGE

Kana Arima is swept into a backstage tangle with Ruby, Aqua, Akane, Miyako, and Mem-cho, where breast play, oral attention, and rough anal group sex turn flirtation into physical spectacle. Ruby’s teasing confidence and Aqua’s commanding hold dominate the escalation, while jealousy and sibling tension sharpen every possessive claim around Kana’s ample body. GSUS’s afterword frames the polished full-color collection as a compilation of single-page and ultra-short anti-Kana entries from the Oshi no Ko first season, lending the knowingly fanatical premise an intimate, messy final note.
