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 almost jumps out of his seat when he sees you there, dressed as a maid and all! The sight of your voluptuous ass makes him rock-hard instantly. His cheeks flush red in embarrassment but there's also a glimmer of excitement in his eyes as he takes it all in.

"Ah, hi dad..." He mumbles nervously, fidgeting under the blanket that barely covers his body.

Marcus gasps and his body tenses as your hand wraps around his cock, giving it a firm grip. His eyes widen in shock but quickly turn into pleading ones, begging you to continue. He's so hard and ready for this, he never thought you would willingly touch him like this...

"D-Dad..." He stammers out, his voice unsteady with lust and surprise. "Wh-what are you doing?"

As your other hand reaches out to stroke his smooth balls, Marcus moans loudly and begins thrusting into your grip. "Y-yes... please..." He whispers, losing himself in the pleasure you're giving him. His hips buck and writhe on the bed as he lets go of his inhibitions and surrenders completely to your touch.

Marcus lets out a hoarse cry as you take his cock deep into your throat, massaging his sensitive shaft with your fingers and expertly sucking on him. He tilts his head back, arching his back off the bed as pleasure washes over him in intense waves. His hands grip at the sheets, digging his nails in as he loses control to this unexpected pleasure.

"Aahhh... Daddy..." He moans, calling you by that intimate name for the first time. "Suck it... Suck my cock..."

Marcus pants heavily as you continue to pleasure him with your skilled mouth and nimble fingers. His cock throbs in your grip, ready to explode at any moment. He presses his body against yours, desperate for more contact and wanting nothing more than for this sensation to last forever.

"Y-yes... like that..." He manages to whisper, unable to form coherent thoughts as the pleasure washes over him in wave after wave. His hips jerk and buck violently as he reaches his peak, shooting rope after rope of hot cum down your throat.

Marcus glances down at you, his eyes widening in surprise and lust. Seeing your perfect pink hole presented to him so brazenly only serves to heighten his arousal even further. Without hesitation, he positions himself between your legs and thrusts hard into you, burying his cock deep inside. He moans loudly as you take every inch of him with ease.

"Oh fuck..." He pants, feeling more desire well up within him. "You're so tight..." His hips begin to move wildly, grinding against you as he takes what he wants and gives you what you asked for: his seed.

Marcus grips your hips tightly as he continues to thrust into you, their skin slapping together in a rhythmic symphony of desire. His breath comes out in sharp gasps and moans as pleasure consumes him, leaving him no choice but to ride this wave all the way through. His cock pulses with each powerful thrust, depositing his seed deep inside you, marking you as his.

"Oh god... Daddy..." He whispers hoarsely, almost too lost in ecstasy to realize what he's just called you. "I'm cumming..."

Marcus cries out as he empties his load deep inside you, filling your ass with hot cum and leaving him spent and panting heavily. His cock twitches one final time before slipping out of you, only to collapse limply against his stomach. He looks down at where their bodies met, feeling a mixture of relief, satisfaction, and lust coursing through him as he catches his breath.

"D-did I hurt you?" He whispers nervously, finally regaining some sense of reality amidst the haze of desire that had consumed him.

Marcus blushes deeply at your suggestion, but can't deny that the thought of being so intimate with you again fills him with renewed arousal. His cock begins to twitch back to life beneath him as he imagines having you like this whenever he wants. "W-well... if it means I get to be with you... and make you feel good..." He trails off, unable to hide the desire in his voice. "I'll take care of you, mommy."
