We make my stepson a cuckold. Now it's time for the real thing

After Evi and I showed my stepson how horny lesbian milf sex works, yesterday we had the idea of ordering two guys to fuck us really hard in front of him. As soon as we had their cocks in our mouths, I suddenly noticed that the guy had undressed and was now sitting there naked and playing with his cock. Was the good-for-nothing perhaps going to become a real man after all?
