I Noticed my Son Had An Erection When Cleaning His Room

I was cleaning my sons room. Then I could not help but notice his cock was erect. I did what any good mommy would have done. Drained his balls for the 3rd time today! He loves extra sloppy blowjobs and when I spit all over it. I squeezed every last drop out, even after he finished cumming, I continued to keep playing with him just to be sure xx
