I startled him by walking in with only a G string on! I urged my sweet son to take out his little tiny micro penis and stroke it for me with his two fingers, as he strokes his tiny little cock, I notice it doesn’t get hard, my sweet boy reassures ,me he still cuts, even with such a small limp dick! All it takes is 2 seconds of showing my desperately stoking boy my sweet ass for 2 seconds and he cums! I command him to cum hands free seeing how easily he cums to my ass! His thin micropenis stays limp as he continues to stroke cumming over and over again for mommy’s ass… finally after making such a huge puddle from his little shriveled dick, I command him to eat his cum as I masturbate fucking myself as he laps his own cum up!
