[Hijiri Tsukasa] Jerk-Off Assistant! CH4 Masturbation Assistant Big Sister Mom (ONA-ASHI! ~Ero Mangaka no Onanie o Tetsudau Shigoto~)

A stressed manga artist receives a comforting meal from his big‑sister‑type assistant, who promptly offers to relieve his tension with intimate, clothed paizuri and other sexual favors. She teases him, pulls down her top to reveal her ample breasts, and invites him to join her, leading to a series of playful, erotic exchanges that culminate in a satisfying climax. The story ends the next morning as she wishes him good luck and he returns to finishing his manuscript.
