Open mind stepmother helps her stepson boner

This hot mom always gets lots of free clothes because she leaves reviews with multiple photos on the website where she gets the clothes. It's a way the brand has to thank for the positive review, and also to do marketing. This time, she received a sexy lingerie and asked her stepson to take the photos for her, because her phone had the camera broken and he wouldn't simply give her his phone. She tells him they should go to the woods to take some pictures. When he sees her wearing that sexy lingerie, his dick started growing. She notices and starts messing with him. She's so open mind and easy going that, she tells him to take his penis out of his tight underwear so it can properly breathe. He put his dick out while taking photos of her. His dick keeps getting harder. She tells him: that's not good for you, it's not healthy... you really need to ejaculate. You should masturbate.
