煌きの姉弟妹 ～SEX CRIME～
A brother and his younger sister have lived together for a long time, sharing a close and affectionate bond. As they grow older, the brother begins to develop feelings that go beyond sibling love, struggling to keep his emotions in check. The daily routines and quiet moments they share become charged with an unspoken tension, as he fights against the growing attraction he feels toward her.
Despite his efforts to maintain a normal sibling relationship, the line between familial affection and romantic desire blurs with each passing day. The sister, unaware of his inner turmoil, continues to act naturally, which only deepens his conflict. As the pressure builds, the brother must decide whether to suppress his forbidden feelings or risk everything by revealing the truth, knowing that crossing that boundary could change their lives forever.
