HMN-342 Dear sister-in-law.....

I like looking at your cute school uniform. In a daily life that doesn't change like this, something white catches my eye. Hey, there's something on your uniform. 'Oh, this is nothing, it's just dirt.' Do you have sex with someone at school? Will she come to class wearing the sperm-stained uniform and take the train home? I can't forgive that... Who smeared sperm on her uniform? I get hard while crying with regret and sadness.
