Zorrita forced to fuck without knowing it with her own uncle

If this fox wants to enter the fraternity of the university, she has to pass a test imposed by the group leaders. They cover her eyes and take her to a room where she is forced to fuck a stranger: an old man who also has his eyes covered. They do not tell anyone that they are fucking a person in their family, since the old man is the uncle of the girl. When the grandfather runs into the niece's pussy, they remove the blindfolds and then discover that they have done incest, something that leaves them shocked.
