Be careful your past my catch up

I've been fucking Japanese couples for a long time, and never thought much about it till today. I received a letter that had a picture and note in it. The picture was off three lady's
one my age one mid twenty's one one year old. The note said mother,daughter,grand daughter/daughter. Yes that's right the young couple that came out a couple years a go was my daughter and no one said a word, till now. I don't know what to feel Dam never thought.
