Considering that the stepfather and stepdaughter are almost the same age, I don't see anything shameful or surprising about that. Sooner or later, when the wife should have left, the stepdaughter herself would have insisted on this action. Which is actually evident in the course of the video. The stepdaughter immediately exposed her breasts without thinking. Liked her intimate hairstyle - in times of fashion for naked pubes, such exhibits cause additional desire!
Chicks, when they bathe, are always groping themselves. Their whole body is an erogenous zone. But how could such a beauty neglect their breasts or, for example, pussy? No way! So she got right into it with a vibrator. Only hubby decided all his own way - let her suck bitch and his bolt to please. And she didn't mind - she immediately grabbed it in her mouth and stood up. I'd have worked that asshole full, too. I'd have her screaming and begging for more! I love such frank chicks who have a weak front.
