My Wife's Surprise

A man has a fight with his wife.  When he leaves the house she decides that she can get even with him by making him her cuckold.  She calls a man that she knows and asks him to come over for some fun and games.  To her surprise, he brings three other men with him.  One of them suggests that she be tied up and she agrees.
When the man comes home he is surprised to find his wife, in the entryway, still bound with chains and locks and with a hood over her head.  Having no idea what has happened he tries to get some information from her but since she also has a gag under the hood she is unable to converse with him.
