The unfortunate coincidence is simply hilarious. Since the choice of image is completely random, some players have gotten an image of fried shrimp in Hanako's route, after she shows Hisao her severely burned body.
Once the sex starts, the game flashes to a random, unrelated image, and then cuts to after the sex ends. Disabling adult content can lead to a complete mood whiplash because of the way that sex scenes are censored.
