A risky blowjob

Don't do this irl, please.

You estimate that you have enough time left.

You turn to your mother and see that her huge dick has crept its way halfway down her left pant leg, stretching out the suit's thin silk fabric with its immense girth. A large and prominent vein on its side pulses softly and hypnotically, visible even through the cloth. Lisa is focused on the traffic, but you can tell that the arousal is starting to get to her as well, because she is breathing heavier than normal and subconsciously squeezes and readjusts her fat bulge every couple of seconds.

"Mom!"

"Hmm? What is it, sweetie?"

"Get that cock out of your pants, I need to **** on it right now! Your slutty son demands your massive bitch breaker in his throat, and then your hot seed in his belly!"

She snaps back out of whatever daydream she had and looks down at her huge bulge, the traffic around her, and then at your hungry gaze as you stare directly into her eyes. She freezes up for just a second, then slams her right hand on the button for the warning lights, which will alert the other drivers that there's sex happening in the car. Safety first.

In this time, you've already reached over to her pants and opened her belt buckle. You impatiently pull down her fly, and Lisa helps you by lifting her butt off the seat a bit, which allows you to yank her pants down to her knees in one go. A wave of intoxicating deliciousness hits your nose as her meat stick comes into view. You lean down to press your nose directly against her pulsing member, snorting in a deep whiff of her musky aroma. The smell fills your entire body with a heat rush, and your anus starts to clench and unclench on its own, desperately awaiting a cock to obliterate it.

"Snnnnnnnnnnnnnrthhhh!"

"Go on then, you needy little nympho slut! You want to **** on it? Go ahead! But you'll finish what you've started, young man, and if you let even just a drop of my cum spill on my pants, there will be hell to pay!"

You only register this in the back of your head, as you lovingly lick her rapidly stiffening cock from base to head in a single go, leaving a trail of saliva behind. Your right hand grasps her engorged cock head, the thumb massaging her glans again and again.

In no time at all, her cock starts to raise by itself from between her thighs, and your work begins in earnest. While it's not fully hard yet, you pull it over to get a better angle, and are again looking directly down her massive cockhead. Her urethra winks at you in sync with her heartbeat, and you dive in to plant a wet and sloppy kiss on her huge cockhead.

"Hnnngh! You... slutty... wonderful... little... biaaaaaahhhngh!"

She grips the steering wheel with her left hand, puts her right one at the back of your head, and unceremoniously pushes you down her cock. You manage to open your jaw wide and relax your throat just in time as her hot flesh rod spears deep into your throat. By now, your own cock is as hard as your mother's, straining against the red hotpants you're still wearing.

With an unrestrained loud moan that turns several heads on the sidewalk, she continues to push your head all the way down to her fat balls, which are squished between her thighs to appear even bigger and fuller than they probably are. Your tongue continues to lick and slurp her huge cock the entire time, and your throat milks her shaft on its own, trying to coax it into releasing its rich cum directly into your belly.

Lisa moans and bucks throughout the entire blowjob, but does a solid job of driving, considering her state. You've lost track of where exactly you are, but you reckon you're fairly close to the school. Lisa starts to breathe in short gasps, her moans grow increasingly high-pitched and you can feel her dick expand the slightest bit more, and you can tell that her orgasm is close.

Now on the home stretch, a wave of vigor surges through you and you redouble your efforts, applying every trick you know to get your mother's sweet nectar out of her swollen balls.

She screams in ecstasy and your throat registers the pulses of her hot cum traveling up her cock and then shooting directly into your stomach. You can immediately feel her delicious and nutritious cum fill your belly, and you moan in satisfaction around her trembling dick. She bucks and stiffs and slams the gas pedal all the way down, as the orgasm rocks her body.

"Fuuuuuuuuuuck! Oh fuck!"

She releases her grasp on your head and yanks the steering wheel to the side, causing the car to turn sharply, which in turn causes your body to press your head even deeper into her groin with considerable ****, spearing the last half-inch of her still shooting cock past your wide-stretched lips.

"Gnnnnnghnnnnnngaaah!"

The car makes three complete circles in what you realize is the big roundabout in front of the school, with your mother locked in orgasm, and you down her spewing cock. After the third, the car plows over a sidewalk onto the school's grounds, wipes out a 'Stender - Industrial Strength Viagra for the entire family!' commercial sign, and comes to rest on a grass patch just a few meters within the school's boundary.

You slowly pull up, your jaw straining a bit from the rough treatment, and the two of you take in your surroundings while catching your breaths.

After a couple of seconds, the driver's door opens and Mrs. North, the school's principal, leans in and grins at the two of you.

"Oh, to be young again."
