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 :-)
Not fully understood what the stepmother was talking to him in the beginning, but judging by the further development of events, obviously complaining about his hard feminine lot - large breasts, in her case, which is difficult to wear without constant massage. And the massage of her breasts, as well as of her whole body. And that's what his dark-skinned girlfriend was talking about, before she went to bed with them, I understood at once - she sympathized with her stepmother and offered her help! That's how it was, wasn't it?
