Your son, seemingly in his sleep, moves a little closer and pushes half of his shaft into your pussy. But, perhaps to your disappointment, he simply leaves his body and cock at rest there, within face between your bosom. He also wraps his lips around one of your nipples and begins sucking milk from your tit. Was he really fucking and sucking in his sleep?
Unless you entice him further, it looks like he's done moving around and will rest like this for the remainder of the night.
