[PLEIADES☆FORTUNE (Kaniyama Yuusuke)] I LOVE YOU, Onii-Chan!! But We’re Not Related! [Shiro Translation]

Hazuki-chan arrives to apologize to her beloved Onii-chan only to find the tall, possessive beauty who lives with him waiting instead, instantly jealous over whether Hazuki has already gotten pervy with Sakagami-kun. Teasing about her small, sensitive breasts turns to relentless fondling, and soon the flustered girl is wet, trembling and losing strength as slick fingers and hungry cunnilingus overwhelm her protests with naughty, melting pleasure. Caught between her earnest devotion to Onii-chan and a dominant woman determined to steal her first time for herself, she is coaxed toward a betrayal that feels impossibly good to resist.
