In this version the lady was very lucky - she met a very temperamental and persistent man - he fucked her long and gentle enough! And quite safely - with a condom. Apparently the man likes such thin women. But the lady didn't have time to show her abilities as a masseuse - neither on a man's body, nor on his cock! Maybe she is not a masseuse, but a lady on call?
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?
If I had a secretary like that, she wouldn't come out from under my desk. She sucks pretty good, you can tell she's great!!! And she's got a great figure. I'd fuck her till the end wore off.
