Cuckold knows what promises she makes.
She had risen early this morning and left your hotel room without even saying good morning. You went to find her down on the beach and after looking for over an hour you found her with him naked together on the shoreline.
It is clear to you that he has penetrated your Wife with his cock and she is enjoying the feel of him inside her. Oblivious to you standing just a few yards away she and him orgasm heavily together while you have to stand and watch, saying nothing, as another man empties his seed into her.
Emptying his seed inside your Wife.
If you had any doubt before, you now know that you are a cuckold. But the question is; how do you react to this?
