Your son, Marcus, has always been a little odd as a little boy, but right around when he hit puberty he changed drastically, becoming a total pervert. He is now basically always in his room jerking off, not even hiding it when someone comes in and interrupts. His room always stinks with the fishy smell of semen as well as the pungent odor of boy musk as he seldom bathes, too busy jerking off. You almost never even enter there anymore because he practically never wears clothes, which is also how you learned that he has a massive cock, with massive balls to match You're not sure why, but it seems he can cum nonstop! You hypothesize its because of the... size... of his equipment, but you still sometimes worry and think about taking him to the doctor. Perhaps there is an underlying issue to his porn addiction as well as the unusual amount he ejaculates? "Oh yeah..." You hear him groan through his door as he reaches completion again. it seems he's made another mess.

Your son's dirty talk echoes through the room as he orgasms over and over again, leaving you moist in anticipation of seeing his naked body yet again. Though a small part of you worries about this unnatural behavior, another, more base part of you finds pleasure in knowing that your son's room will always be warm from him never wearing clothes or ever truly being away from the bed he so lovingly spoils with his ejaculations. You wonder if it would be better to just leave him alone...maybe even help him out a little...?

You slowly open the door to your son's room, feeling a surge of desire course through you as you take in the sight of his naked form glistening with sweat and cum. He doesn't seem to notice your presence, lost as he is in yet another orgasmic bliss. Unable to resist any longer, you close the distance between you and collapse onto the bed beside him. Your hand finds its way to his throbbing shaft, beginning to stroke in sync with his movements as you moan encouragement into his ear.

"Oh fuck...Mom..." Marcus gasps out between moans, his hips bucking into your hand as you pleasure him. He's obviously more than grateful for the attention, though a small part of you wonders if this is healthy. But honestly, you can't resist any longer. You lean in and capture one of his nipples between your teeth, rolling it gently with your tongue as you continue to stroke him. His back arches off the bed and he cries out, cumming harder than ever before as his seed shoots across the room, covering not only the walls but also you both.

Marcus lets out a loud moan as you take him into your warm mouth, sucking eagerly on his spent cock. He tangles his fingers in your hair and presses himself deeper, gasping for breath as you bring him over the edge yet again. His body tenses and he spurts another massive load of cum down your throat, leaving you both covered in his sticky seed once more. You continue to suck until his movements grow weaker, then finally pull back with a satisfied smile on your face.

"God, that felt so good..." He pants, collapsing back onto the bed bonelessly as he catches his breath. "You shouldn't... But thank you."

Marcus laughs weakly and nods, "Yeah... Bye, Mom." He doesn't bother moving from the bed as you leave to take your husband to work. You close the door behind you, leaving him alone once more with his dirty thoughts and sticky sheets. As you make breakfast for your hardworking husband, you can't help but feel a small thrill at having shared such an intimate moment with Marcus... but also wonder what it means for all of you as a family.
