Yu was sincerely congratulating her happy daughter who had a boyfriend. Therefore, I often invited my boyfriend to serve meals and warmly watched over the two young mothers. However, on the other hand, I also felt loneliness. I am not satisfied with the couple's life, which is decreasing as opposed to my daughter who is becoming feminine. Yu forgets that her daughter and boyfriend are in the next room and indulges in masturbation. And so much that he is absorbed in pleasure, he provokes his daughter's boyfriend with bold fingering without noticing that his daughter's boyfriend is peeking in with excitement.
