'Hello, my soon-to-be personal cushions,' Kevin mused in his mind as he observed his mother's large, soft buttocks emerging from their confinement. It wasn't as if he hadn't seen them before; he'd witnessed them grind against his penis at night when she did so naked.
However, now, in the daylight and with her permission, he had the opportunity to see them fully, which excited him. They were still covered by her black panties, nothing too fancy, just her usual undergarments, as Kevin had seen too, before.
As he started to pull them down, she stopped him, saying, "Hey, why do you have to take them down? Can't you apply the cream with them on?"
