Yoshikawa-san no Junan

Yoshikawa is a quiet girl who responds to an invitation for a part time job. However, she is put to sleep with a drug.

During her sleep she is raped by a large number of men, who ejaculate into her mouth and onto her face until she is drenched in semen...

This is an original short story about gang banging a sleeping girl.
