MIAA-293 The virgin younger brother, taking his sister's provocation seriously, doesn't notice he's climaxing and keeps pounding away. Eimi Fukuda

Eimi jokingly teased her younger brother for not being popular with girls. Her virgin brother mistook the joke as a genuine invitation and immediately penetrated Eimi right after their parents left. Although Eimi climaxed from the sudden intensity, her inexperienced brother didn't notice and continued to thrust wildly. Despite reaching orgasm multiple times due to the ongoing sensation of his thrusts, Eimi couldn't resist and was made to climax repeatedly until just before their parents returned home.
