[Sena Youtarou] Perverted Onei-chan Ch. 1

A bold older sister with a ponytail and glasses returns home with her younger brother, announcing "WE'RE GONNA GO AT IT LIKE RABBITS TODAY, LITTLE BROTHER!!" as she eagerly strips him of his pants. The chapter escalates as she rides him with her well-endowed figure on full display, her expressions shifting between lustful dominance and blissful submission. The finale delivers a teasing coda where she reflects on her newfound "masochistic nature" while her exhausted brother scrambles to set a "thrusting half of those" for next time.
