Doug is allowed to take his time and give Fiona the best blow job he can.

Doug, in his apprehension, underestimated the thickness of Fiona's aching penis. His mouth, not open nearly wide enough to accommodate her girth, only allowed the bulbous head passed his pursed lips where he pressed them together to give the dripping tip a wet and sloppy kiss.

The giant girl moaned her pleasure, her head tilting back, her long hair cascading over her shoulders like a soft river. Beneath the back of her dress, she clenched the bubble cheeks of her butt hard, fighting back the rising wave of euphoria that she knew would soon explode. **** to prolong the ecstasy, not wanting to end all of this to quickly, she squeezed back her excitement and let out a long sigh as she felt the smaller boy's nimble tongue dip gently into her slit.

"Duh ... Doug! MMM!"

Encouraged to go further, thinking about what he knew would make him feel good, Doug took a deep breath to steady his hands. He swallowed, tasting the salty sweetness of Fiona's precum on his palette, and felt large hands begin to curl around his neck. Fingers wrapped themselves into his hair, clenching a firm grip, and slowly, steadily, Doug felt the building pressure of her cock as the girl began to push her wide hips forward.

She was strong, big and powerful, and he knew that demanding rod of steel hard flesh would not be denied. His own fear beginning to rise again, Doug felt weak and almost helpless as her shadow seemed to stretch over him, blocking out the light filtering through the open windows. The pressure was building on his face, her grip tightening across his neck and shoulders, and he did the only thing his nervousness would allow, he opened his lips slightly.

The effect was immediate, with a jerk of her hips, Fiona felt her thick penis press up against the hard surface of his teeth. She grunted, clenching her ass cheeks again and letting the wave of pleasure pass through her to sink down through her groin. Jerking again, another thrust of her hips, and the giant girl felt the barrier resist her once more.

"Please ... puh ... PLEASE!" Doug felt those long fingers leave his shoulder and slowly slide their way across his cheek. They blazed a hot trail, tickling his ear inadvertently, before moving down to his lips where Fiona began to **** her thumb inside. At first she just tugged on his teeth, but slowly began to push harder and harder as she worked to **** his jaw apart. "I ... I won't hurt ... you..."

The smaller boy complied, unable to resist any longer, and slowly opened his mouth wider. Fiona's head tilted back in her loudest moan yet; it filled the house with the rattling sound, as her demanding cock sank into the warm, wet confines of Doug's mouth. The fat head scraped across his teeth, contracting slightly like a swollen sponge, before ballooning back its full size once the curved rim of that massive tip cleared the barrier. His cheeks bulged with her size, the thick rod pushing his tongue down and out of the way, before pressing up against the back of his throat where it almost made him gag.

"YES! Fuh ... fuck, yes..." Fiona's meat quivered, a surge of pleasure causing it buck, and a fresh spurt of precum to spill forth. It filled every last bit of space, more in volume than Doug could produce in a full session, and he struggled to swallow it down. His tummy felt warm with it and more would soon follow as Fiona stood tall, the small boy between her long legs. "I knew this would feel ... AMAZING!"

Doug's neck gently snapped back as the giant girl began to pump. Even though her hips only gave small thrusts, it was enough to cause his head to jerk back and forth as Fiona began to use his mouth to pleasure her hot flesh. All he could do was grunt softly around her girth, struggling to breath through his nose, and hold on. Both of his hands, unable to encompass the width on their own, worked together to wrap around the root of that monster. Doug could feel her heart throbbing through it, pulsing the thick veins to push at his palms with every beat, as he massaged and rubbed the base of Fiona's cock.

One hand broke free, sliding across the trim hips of the thin but incredibly tall girl, across the top of a slender thigh, and down to cup the smooth sack of her bulging testicles. Doug's eyes went wide, amazed at how just one of those swollen globes filled his entire palm. There was a solid weight to it, a heat with thin slickening of lightly salty sweat. It dripped down his fingers as he gently massaged, rolling each of her balls back and forth. He felt them contract and rise as Fiona moaned, squeezing her ass with greater frequency as she struggled to hold back her eruption.

And Doug continued to suck.

Rolling his tongue lavishly over her head, it worked to **** its way around with the cramped confines of his mouth. He realized he loved having Fiona's size filling him. Her cock was big, stiff, and in control of him completely. It was hot and alive and inside him. He wanted it there as long as it could be. And, as gently pressed it up against the roof of his mouth to squeeze it lovingly, he realized it was slowly getting bigger after it ballooned back to its full and epic size. His jaw was aching, struggling to open his mouth wider and wider. Doug's cheeks had billowed outward to contain its load. As Fiona shifted back and forth on her large feet, the tip bulged its way from side to side. And she was continuing to moan louder and louder.

"Doug! DOUG!"

Her thrusts were getting more and more forceful, her balls slapping against his chin so hard he though they would bruise him, and she was beginning to **** more and more of her length into down his throat. Doug had to lean forward slightly, grant the fat tip safe passage, and ease the pain that was building as it pushed its way passed his tonsils. The smaller boy's neck bulged, his eyes red and watery, and he struggled to breath as he got up on his knees. He had to stop this, his gags unable to dislodge the massive intruder that was slowly, but surely, penetrating deeper into his tender and fragile body. Squeezing her shaft only encouraged her, the giant girl loving every stroke and tug on her sensitive flesh. And she was too tall for Doug to wave and get her attention; especially with the haze of euphoria in her eyes and the tilt of her head as she lost herself to the building lust in her groin. ****, out of options, he did the only thing he could think to do.

Dropping Fiona's heavy balls, allowing the slick, sweaty sack to drop from his tired fingers, Doug moved passed them to find the excited and swollen folds of Fiona's tender pussy. Her clit was stiff, protruding strongly from its hood just passed the valley between her smooth scrotum, and the giant girl screamed as his fingers slipped across it before dipping them into the parted lips deep inside. She clenched again, squeezing Doug's fingers, and the sensation finally pushed her over the edge.

"YES! YES! FUCK!"

And Fiona's massive penis began to buck.

It shook Doug's whole body with the **** of it, her whole shaft trying to rise, and the entire girth of it swelled within the tight confines of his throat. He felt the mushroom tip bulge, grow inside him, and then the first volley spurted forth. Immediately Doug felt full, the splatter of Fiona's cum pouring into his stomach and her big penis continued to buck, not nearly finished with her orgasm. She was lost in the joy of it, her love gushing forth in waves into the small boy she had adored for months. Her fingers clenched hard into his hair, hips pushing forward to bury as deep herself as far as she could, and trickles of her pleasure was starting trail out from the tight seal around her cock and even a small line out of his nose.

It felt like it was going on forever. The pressure was too much for him to bear and Doug was finally able to lean back, pull himself off of her incredibly massive tool where he coughed up a huge gout of her ejaculate. One hand still held onto the giant girl's penis as the gushes started to come in smaller and smaller bursts, until the whole of it just throbbed and flexed in impotent pumping. His face was covered, his shirt soaked in the remnants of her pleasure, and Fiona fell back onto her rump with one final moan. The floor shook with the **** of her giant body as it impacted, and she sat there with legs spread. Her big feet stretched to either side of the smaller boy and her thick erection towered up, rising from her crotch like the boom of a crane, but slowly deflating as it began to sink to its rest across the thin toned muscle of her thigh.

Her breathing was heavy, the front of her dress damp with her sweat, and Fiona gazed lovingly at the used boy in front of her. So small and cute, she thought he was perfect, even soaked in the flood of her cum. Her smile was warm and genuine, and she grunted one last time as her cock throbbed, pouring a final spurt of her cum out of her aching slit.

"Thank ... you..."

Doug **** a weak grin, his lips dripping. His throat was sore and he coughed up a glob of her spunk that he struggled to swallow back down. He didn't want to hurt her feelings, realizing his own feelings for her. But she was so tall and big, the knowledge that she was likely to grow even bigger still weighed heavily on his mind. Yet, her face was so beautiful and he had always thought she was pretty.

Swallowing once more, wincing at the pain he found in his neck, he opened his mouth and in a course voice he said...
