You weren't sure what was going on in your head, but honestly you felt like it would be hotter of the situation were different. Instead of your mother, you imagined she was one of your younger twin brothers, each thirteen years old. Or possibly even younger. But you look down, enjoying that hot mouth on your cock, when you notice her changing. Her breasts were shrinking, her torso shortening, getting skinnier. Her ass got plump, and her legs skinny and short. Between her legs sprouted a small pair of balls abd a small cock, and her hair got shorter. Her face became more boyish, and soon your mother had the body of a seven year old boy. You were shocked, but you couldn't help the fresh orgasm that she...no, he had brought you to. The young boy swallowed it up eagerly, panting as he finally pulled off. "I need you in me," he said, turning around and bending over.
