This time the target is Ruka Ishikawa. "The hardest thing I can do is Deep Throating," says Ruka. She insists that she can do things she doesn't know, so she experiences real deep throating so that she can think that the deep throat she's had so far is 'just like a blow job.' Waiting for her is hospitalization, or... Such an outrageous real document that gives a complete public toilet training to the back of the throat of a pure girl who made her debut as a virgin. Ruka Ishikawa's complete training is not strange, but this work is pretty bad.
