Becoming a man.
Little Daniel had been the latest of the Branson family to turn 18.
And just all of his 10 brothers before him, his 18 birthday had been mostly filled with moaning and puffing as his tiny little frame suddenly swelled with muscle and testosterone.
It had been a stressful day for him, he had woken up frail and weak and with a body that would be put to shame by most 12 year olds, and by the time he blew out the candles on his birthday cake his clothes were bursting and was he growing a beard. “Just is the Branson way, lil Danny” His uncle would rumble while shoving cake down his extraordinarily muscled neck. “Why do puberty over 6 years when you can do it all at once.” His bodybuilder sized farther would chime in.
But in between all his older brothers and nephews wanting to compare cock sizes and some distant uncle trying to tell him about the birds and the bees in the most erotic way possible Daniel just couldn’t wait for this day to end. So he had sneaked out, and had been quietly growing in the backyard against the wall for the last thirty minutes. Well, as quietly as you can call whimpering every time his muscles swelled bigger.
Daniel’s peaceful growth was suddenly disturbed.
“Is that you? Danny, my god you’ve grown!” To Danny’s horror he saw his hot MILF of a neighbor in nothing but a bikini peeking over the fence. “OH, hi miss Clarence.” He meekly called out, his voice alternating between his boyish voice and manly tremor. “Oh I’ve got to come take a closer look at my birthday boy.” She quickly jumped over the fence, her tits juggling wildly as she did so. “I’m very naked!” Daniel called out as a helpless final warning. “A little nudity has never killed anyone. Let me seen how tall you’ve grown!”
It was taking every ounce of willpower within Daniel to not grow hard as his neighbor slowly jogged towards him. In the Baywatch sort of way, where ever hot part of a woman is in full display. “My, my, aren’t you a big birthday boy!” Miss Clarence apologetically eyed every piece of the shy hunk standing in front of her. She bit hardly on her lip and felt pleasure move throughout every part of her body. “So big…” A whimper escaped her lips. “So strong…” She gently caressed his bicep.
Miss Clarence continued her soft caressing, stroking through the new hairs that were sprouting every second throughout Daniel’s body. New shock waves of growth spread through his body, slowly pushing him past 6′4.
“Oh please tell me you got wonderfully spoiled for this big day.” Miss Clarence managed to murmur while her bikini was getting increasingly wet. “My parent’s gave me… gave me this wonderful… wonderful set of…” Daniel interrupted himself. “Aw fuck yeah.” Was all he could say as his biceps grew past 18 inches. He put a hand behind his head, flexing the newly grown muscle and deeply lost in pleasure as his neighbor managed to find new crevices with her fingertips.. “…Gave me this wonderful set of.. of.. of XXXL condoms.”
His cock jumped alive, and even though he was standing in a puddle of his own cum already his cannon or his balls seemed no worse for wear.
As miss Clarence circled his very plump nipples, his pecs growing in the process she slowly saw the last of her shy neighbor drain out of the incredible piece of meat standing in front of her. His unsure moans were traded for grunts, the last remnants of his squeaky voice erased as his tremor took over and he drew short breaths.
“But my favorite birthday gift came from you, Miss Clarence”
“Oh.” She managed to wimper, while Daniel’s thick digits removed the remnants of her soaked bikini.
“Yeah, something tells me this fuck is going to be the gift of a lifetime.”
Danny effortlessly raised her petit form, and smashed her down on his 10-inch cock.
