She's so short! And it's not a midget, it's just a girl with such a short stature. You look at the bald jock and the blond girl, and it's kind of scary for her at first. Fortunately, the bald man treated her gently and lovingly, and the girl was genuinely happy about what was happening.
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?
Why would you fuck her in your underpants?
