On some level, Brendon understood that he was addicted. He had Monica up against a wall, her legs resting atop his massive thighs, his oversized dick rammed in as far as it would go. Still, he tried to ram it in even further, pushing up into her, using his powerful legs and butt to thrust upwards, even as his head was bent down, down to the breasts that Monica held up for him. He sucked fiercely on her succulent nipples, desperate for every drop of milk within her swollen breasts. That wonderful, size-altering milk, pinkish in color, that kept him growing. That kept feeding his hungry mouth, his hungry body.
Monica groaned in appreciation. The potion and Brendon's cum had made her tough enough to withstand having his monstrous tubesteak stuffed into her cunt so completely. When it grew and swelled in response to the growth of his body, her pleasure only increased. Her breasts had swollen to proportions only seen in porn - they were easily equivalent to nicely-sized watermelons. As they had grown in size, they had become sensitive as well. Between Brendon's sucking and fucking, she had achieved constant orgasm.
Brendon wanted – no, needed – more. Much more. He had an idea. Reluctantly, he stopped sucking on Monica’s glorious breasts, and lifted her off of his monstrous, rock-hard dick. He lowered her to the floor, and with a contented sigh, she collapsed into a heap. The sight of her athletic body and gloriously round, ripe breasts made Brendan want to start fucking her again, right then and there. Instead, he lowered his large hands to his own dick, and grasped firmly. The heft and girth of his fuckrod surprised him – he was surprised that it could even stand up, given its size and the power of gravity. He ran his hands along the tapering shaft, still slick with cum and Monica’s juices. He reached the head, and squeezed it, feeling the electric sensations that traveled the length of his cock and reached his brain. His hands worked their way down again, and then up, several times. Each time, the pleasure increased, until he felt something build up in his balls. He brought his hands forward just in time to catch a large wad of cum, which his oversized manmeat happily expelled. He brought his hands up, and inhaled the aroma of the sticky pink substance filled them, and then slurped it all up. It was bitter and tangy, and slid down his throat easily. He licked his hands clean, even as he felt a tingle spread throughout his body.
Brendon threw back his head, and roared with ecstatic rage. He could feel his muscles swelling with size and power – no, he could see them swell with size and power! His hands flew to his dick, and he jacked himself off furiously, watching his growing reflection in the mirror. “Oh yeah…” he managed to moan, “fuck yeah…”
More cum shot from Brendon’s dick. He brought it to his mouth, and drank deeply. The tingle of growth became stronger. And his hands reached for his cock, eager to coax out more.
