You are my sweet dear son and since the divorce from your father… you have secretly been taking SUCH great care of your mother. And I can’t get enough of this big beautiful cock! You have become such a beautiful boy… and taking care of your mother in this way….. its just all too much for me to resist! We are having some amazing quality time together as mommy sucks and fucks you, worshipping your big dick, slobbering all over you, gagging on your cock. Its just really so much COCK for mommy but… its exactly what I need. And you know just how to use it, don’t you son? You know how to make your mother happy. I suck you, ride you cowgirl and reverse, and just as you’re making mommy explode, we seem to have some visitors in the window! This sends me absolutely over the edge and I start to REALLY cum on your cock!!! But… then your sister bursts in the room just as I’m coming too! I guess we can’t keep this a secret for too long anymore, son. Sister is shocked and surprised but even MORE surprisingly, she wants some of your big dick too! Mommy understands. I encourage you to fuck your sister as I help to bounce her ass on your big thick cock and we encourage you to cum inside her… maybe its time for us to grow our naughty family now that deadbeat dad is gone? All I have to say is… Son! You are REALLY filling in for Dad!
