SSNI-394 Nene Yoshitaka is bound to a fixture and subjected to repeated restraint and sex.

A room with fixtures, and Nene, who doesn't know what will happen, is clung to the fixture by black-masked men without a word. Nene gets angry and trembles with anxiety and fear, and they forcibly insert a cock into her pussy, swinging their waists without stopping. She ascends many times, tied on the verge of fainting with another restraint device, and attacked again in a pleasure hell that lasts forever.
