Mother's best friend

My mother's best friend, Rena, came to visit us. Apparently, he'll be drinking at home today. In place of her mother, who is preparing for the party, she ends up talking to Rena. I have no immunity to women, so I was nervous, but I managed to talk hard...and while looking at Rena, who is so beautiful that she couldn't believe she was her mother's friend, I ended up fantasizing about not being able to go wrong...
