He cheats on his sister on Valentine's Day so he can fuck her

Valentine has arrived and it is the perfect time for this uncle to take advantage and penetrate his sister as he has been wanting to do for so long. What she does is cheat her and tell her that she has received a lot of romantic postcards and even chocolates while she has not received anything. Then he puts his cock inside the box of chocolates and tricks her into sucking her so he can fuck her later. When he has already penetrated her by being sad and heartbroken, what he does is to confess that the postcards and chocolates had not given them to him, but that they were really for her.
