[Arima Zin] Meshia Girl (COMIC SIGMA 2016-11) [Nisor]

A busty short-haired traveler strolls into a small hot spring inn, only to find her young attendant wielding a shockingly well-endowed guest who is audibly pleasuring himself. Her curiosity and indignation war with one another as she confronts the brazen boy, who shamelessly continues even as she scolds him. She soon shifts from outrage to fascination, offering to "teach him a thing or two" before the situation escalates into a steamy, one-sided encounter where she ends up servicing his absurd anatomy while he delightedly directs her every move.
