Nao works at a so-called "black" company. (A business which exploits its employees.) Day in, day out, she works unpaid overtime... and her heart and body are nearing their limits.

Why are his hands touching there!? Before she knew it, he was feeling her body up and down... Unable to resist, she is rubbed, groped, plucked and... gushing wet. Truth be told, these two have harbored feelings for one another for quite some time... but have been unable to express their feelings and confess. While their bodies are honest... their feelings are not...
