My Sister’s Devoted Care #01 – Akari

Synopsis

An overprotective older sister with a soft spot for her younger brother helps him with his studies and personal hygiene. While bathing him, she notices his arousal and decides to help him clean up properly. What starts as innocent washing gradually escalates as the sister’s feelings overwhelm her, leading to increasingly intimate care that progresses from manual stimulation to oral sex and eventually full intercourse in multiple positions.
