[Shimimaru] Is It True that Libido Increases With Muscle Training (COMIC HOTMILK 2020-06) [AnotsuSagami]

A curious college girl drops into her local SPORTS GYM and fixates on a pudgy, bespectacled salaryman waiting to use the vending machine, teasing him with bold comments about his physique and what a workout might do for his stamina. Oji-san, still sore from a previous session, gets pulled into a one-on-one stretching lesson by the short-haired tomboy, who insists on helping him 'extend one arm lipward'—and soon finds herself lightheaded from his post-gym musk. The lewd premise spirals into a clumsy, sweaty romp as the eager gym rat tackles her much larger partner, breathlessly sniffing, climbing, and clinging to his plush belly until he completely surrenders.
