If a girl has agreed to work as a maid, she is well aware that sooner or later she will have to face her master's cock. To have a good relationship with the client, in her profession, is extremely important. After all, she doesn't turn down money herself. So in her mouth she took rightly, and he pulled her rightfully. And he feels good and she's kind of a stranger. And you do not have to tell the mistress of the house about it - now she is already well provided with tips for additional services :-)
The guy doesn't seem to be satisfying his girlfriend. If he did while he was in the pool, she'd be resting, but she had to keep masturbating herself. Nice color on her skin, her sphincter hole looks really good against that.
