Why I feel pity for those kindergarteners from what they saw about sex in the public and forced them to see it till end??? Its like you are trying to emphasize them to do it even though they are still innocent but it will leave bad stigma for them doing that too while still very young.
I know this is H manga, but at least dont be like that too, voyeurism or exhibitionist is fine, but at least do it on night or secluded place where almost nobody going that place too.
