"If you keep going like this...I'm going to cum..." The guard's relentless physical examination
"You're so wet... are you feeling it during the test?" Even though I don't want to cum, I'm made to cum over and over again, and my body... is going crazy... --Hina is imprisoned for a crime she did not commit. What awaited her there was sexual domination by the ruthless guard, Aki Myojin... Delicate fingering, an obscene tongue, and toys that mercilessly give pleasure.... During the physical examination, in prison, and even during a visit with her lover... Her body is being trained to become more and more lewd. "Help me, I don't want to cum anymore...!"
