Stacy 'rocks' Billy's world

"Urghh..."

A sad, muffled cry escaped Billy's lips as Stacy's punch connected right below his cheekbone, as if a piston plunging satisfyingly inside a groove.

She froze for a moment as she felt Billy's dick twitch against her ass.

"Damn Billy...you sick bastard...", she hissed shakily under her breath. Her fingers trembled as she tugged at the strap of her glove.

A cold sensation swept across her now free hand as she took hold of his dick, the other hand still clenched in a fist, locked on his face.

She felt his dick come to life in her grasp, the veins on its shaft throbbing against her sticky palm.

"Sta...cy...please...I beg..."

Before he could complete, another punch rearranged his words to an incoherent grunt.

"Sta...cy...brghh..."

Another punch, this time followed by a crack, which was painful to hear.

While her gloved hand was busy pounding his head, the other was desperately trying to hold on to his ever growing dick.

"No...not ag...again..."

Stacy didn't realise what Billy meant and assumed it to be yet another plea of mercy.

But what she did realise was his cock had at atleast doubled in girth since his 'punishment' had begun. Like a child feeling her Christmas present through the wrappers, Stacy was trying to measure his dick without taking a peek.

Ever so slowly, she loosened her grip on his thick cock and begun extending her thumb and index finger, tracing the outline of his shaft.

When the combined length of her two digits wasn't enough for her assessment, it dawned on her what monstrosity she was dealing with.

Stacy couldn't help but peer over her shoulder, only to gasp in shock. It was the largest dick she had seen in her life.

And she had seen a lot.

The hypnotic trance of Billy's dick on her was only broken by his wailing cry.

"Phwease...le...me...go..."

"No I won't...", Stacy said matter of factly, as she whipped her head back, "...and stop with the pretence...I get it...you want your roleplay as convincing as possible..."

Billy was too dazed to understand that he had dug his grave too deep. And Stacy was going to bury him, and humiliate him in his epitaph.

"...I know you're just pretending...and I know this is making you hard...and yes... I want you very hard..."

Her last statement was nothing short of an ultimatum.

"St...Stacy..."

Billy mustered his remaining strength to lift his chest up on his forearms, albeit struggling.

"...I...not...pwetending..."

"Aww Billy...", she poked her finger on the ridge between his pecs, pushing him back on the cold floor.

"...I get it...you are 'not' pretending..."

As if to make sure he got his own point across, she punched him again, with the same exaggerated twirl she gave to her hips Billy had taught the moms outside.

"Grghh..."

Stacy kept on increasing the intensity of her punches, as much as her arm could allow. She would quickly glance at his meaty appendage after each hit. This was akin to a ring-the-bell carnival game, where the contestant would strike the mallet to propel the weight up.

The difference being the only thing 'propelling' up was Billy's dick.

Stacy continued to pummel him while salivating over her prize which was getting bigger by the second. Her final punch almost grazed his weak chin.

"Nn...no...not the...there..."

A puzzled look swept over Stacy's face. Billy had been receiving blows on every inch of his face, but the chin was where he was drawing the line?

Billy's wit had been completely mangled under Stacy's fists. He could never get out of this situation with just clever words. A tiny flicker of self preservation had taken over his otherwise broken mind...

..and did what it would to safeguard itself.

Tell the truth.

"That's...my weak spot..."

Stacy stopped her fist mid-air, as if being presented by a fateful truth. She knew what he meant, but still wanted him to validate her suspicion.

Billy, hoping she would spare him if he disclosed his secret, continued spilling.

"My chin...it's dam...damaged...and your gloves...they are...loaded"

Stacy did not understand what gloves being loaded meant, but Billy, the local champ, admitting he had a career threatening weakness was a shocking revelation.

She moved her free digit in a slow yet deliberate manner, and placed it on Billy's chin.

"Is...is this your weak spot?..."

Stacy didn't need an answer as Billy's wince made it apparent.

"Oh my god..."

A fleeting smirk flickered across Stacy's lips. Billy at this point couldn't even keep his eyes open as they were heavy with sleep, and thus was unable to catch her devious reaction.

"...why would you give away such an important secret...something so private...unless..."

Stacy was aroused, her nipples visibly protruding from her gym bra.

"...unless you want me to know this...Jesus fucking christ...the ultimate humiliation..."

She was speaking to herself while Billy kept staring at her like a person under influence.

"I can...I can ruin your life..."

Billy, after all this time, finally realized the web he was entangled in. Stacy felt his dick twitch again, but didn't bother to look back.

"You want this, don't you?...and I want your dick..."

"Stacy...no...", Billy whimpered.

"...as...hard...as...possible...", Stacy declared, each word a menace.

As if her fist had a mind of its own, it dashed towards Billy's chin and connected, a painful echo of a past confrontation.

A darkness swept over Billy's eyes, reminiscent of his foreseeable future.
