[Penicillin XI] Mom's Slight Fever Symptoms (Yokujousuru Karada) [Amoskandy]

A feverish mother asks her young son Atsushi to nurse her back to health, but her simple request for a thermometer takes a turn when he decides to check her temperature somewhere far more intimate. What begins as innocent caretaking escalates as she spreads herself open and invites him to push the thermometer deep inside, moving it in and out until her overheated pussy demands something bigger and harder. By the final page, mommy's pussy is always feverish—and neither of them has any intention of finding a cure.
