Chapter Five
Thomas had to bite the insides of his mouth to stop himself crying out as the effects of the potion took hold. Like the previous times it had happened it was pure agony and he had to grab hold of the walls of the cubicle to steady himself. He was dimly aware that somewhere in the background the Innkeeper and his friend were still talking as they left the toilets together.
"I'll send Alice to look for her, she's probably gossiping somewhere, you know what wives are like...'
As their voices faded down the corridor Thomas was finally free to let out a loud gasp as the pain intensified. It felt like every single one of his nerve endings was on fire as his organs swelled and went into overdrive, struggling to produce and process the vast amounts of hormones flooding his system. He could already feel it burning in his muscles as cells went crazy, dividing and multiplying.
"Please" he begged Hannah, "Make me cum, I need to cum really badly".
Hannah responded with a grin, mistaking his reaction as relief at not getting caught and the effects of the hand-job she'd been giving him. She clasped his cock more firmly and no longer needing to remain silent started to jack him off seriously, her hand quickly becoming a blur along the long shaft. Thomas threw back his head and groaned as she squeezed down really hard, but it still wasn't enough.
"Harder, I need it harder" he grunted, and something in his tone seemed to make her realise that it was more than just lust driving his desperation. She watched incredulously as his already rock hard cock started to expand in her hand, growing larger and thicker before her eyes. Her fingers and thumb which had previously just managed to touch were pushed apart as his girth inflated. Veins that had hitherto been near invisible bulged outwards and the skin stretched to accommodate its immense new bulk. In less that a minute it had gone from just under ten inches to nearer fifteen and counting. It looked like it belonged on a mountain troll or Orc rather than a skinny apprentice like Thomas.
He saw her mutter under her breath, but couldn't catch the words as she quickly knelt before him and began to frantically masturbate his enormous dick. He was now so big she had to use both hands to fully encircle it, and even then barely managed it. Bending forward she fixed her lips over as much of the bloated head as she could. It was far too large for her to fit it all in her mouth so she just sucked on it like a sweet treat, her tongue lashing its sensitive surface and covering it with her saliva. His vision start to blur and he knew that he was seconds away from passing the point of no return and the full transformation it would entail.
Luckily his orgasm arrived first. His entire body went rigid and he thrust forward his hips desperate for relief from the animal urge pounding in his groin. If Hannah had been expecting less cum after his first go then she was in for a surprise. If anything, thanks to her administrations and coming so close to full growth, he'd produced even more sperm than ever before as his gigantic balls struggled to pump out their contents.
The first burst caught her off guard and he saw her cheeks bulge as she struggled to swallow it all. The second burst quickly followed and this time she didn't succeed. Pulling her head back to avoid choking on it cum spilled out of her mouth as the remaining blasts hit her straight in the face. Each shot was followed by another and another and she was left coughing and gasping for air as he continued to douse her with cum.
He focused on her heaving breasts trying to find the still point of calm the way Aurora had taught him. He fought the beast within him and won, dragging himself back from the edge he'd been about to fall off and his body began to relax. Hannah still remained kneeling at his feet looking up at him in a stupor. Her face was almost completely glazed with his cum and if he didn't know better he'd have assumed that several dozen men had deposited their loads on to her. Mercifully she'd managed to shut her eyes just in time so was still able to see.
His cock, slowly returning to its normal size, drooped downwards and came to rest against her face. He noted with exhausted satisfaction that it easily stretched the full length from her chin to beyond her forehead so the sperm still seeping from it dripped down onto the back of her head.
