[Sakujirou] Kyouchikutou (COMIC Anthurium 2020-09)

A conflicted honor student discovers a hidden side of his sister, leading to an intense, power‑playfilled encounter where she is bound, gagged, and forced to obey his commands, her body betraying her with ahegao expressions and uncontrollable wetness. The tension escalates as he teases her with a collar and a clamp, pushing her beyond the limits of what she once considered respectable, while the narrative oscillates between remorseful apologies and raw, dominant desire. The story culminates in a climactic, explicit scene that blends deepthroat, anal, and other fetish elements, delivering a relentless, sole‑female, sole‑male experience that satisfies the most extreme fantasies.
