He cheats on his sister on Valentine's Day so he can have sex with her

Valentine has arrived and it is the perfect time for this uncle to take advantage and penetrate his sister, as he has wanted to do for so long. What she does is fool her into saying that she has received many romantic postcards and even chocolates while receiving nothing. Then he puts his cock inside the box of chocolates and tricks her into sucking her so he can have sex with her later. When he has already penetrated her because she is sad and heartbroken, what he does is confess that the postcards and chocolates had not given them to him, but were really for her.
