ALT Blake, once a normal blonde-haired college student, is now a hulking 6-storey tall giant with huge muscles and a car-sized cock, with tanned skin glistening with sweat under the afternoon sky. His stepdad, Matt, black hair, mustache, stubble, Very handsome; has now grown so large that he barely fits in the mansion's courtyard as he lounges back, leaning against the ruins of his mansion that he had burst out of in his previous growth spurt. As his literally tower-sized cock equipped with boulder-sized balls leans aside and drips cum that slowly floods the estate, he beckons at Blake. Blake, who had been stunned by Matt's new size and appearance, his cock involuntarily splurting cum, seem to have been snapped back into horny reality by Matt's word, thinking to himself, "Oh god. I wanna feel his body against mine!!". He quickly crawls between Matt's leg and towering cock, and up to his stepdad's torso, much to Matt's pleasure. "That's it. Come to daddy!"

ALT Blake is now straddling Matt's upper abs, holding on to Matt's huge, sweaty, hairy, boulder pecs, and pecfucking him. As he feels Matt's body right against his, he thinks, "fuck, I can feel him growing still..." Matt puts his hand together and flexes his pecs, squeezing Blake's dick between them, saying, "Come on, boy. Give your daddy another load!" Unable to hold any longer, Blake humps furiously at his stepdad's pecs, and finally yells out "Fffuuuck!!" as he cums right into Matt's mouth. Matt looks more than eager to accept his stepson's seed, praising his son, "Atta boy," catching as much cum as he can in his mouth, as he himself shoots another load up into the air.

ALT Matt takes a big hearty gulp of Blake's seed, licking his lips as some of the cum inevitably drips down the sides of his mouth into the nook between his pecs. Meanwhile Blake, having spent his load, falls onto Matt's chest, caressing his hairy pecs as he mumbles, "D-dad... I lo..." But before he could fall asleep, Matt grabs him with one hand like an action figure, and places him onto his still-erect cock as he stands up, saying "Don't fall asleep on me now, son. Hold on tight!!" And as Blake wonders what's going on, Matt breaks into a full sprint.

ALT Blake is holding on for dear life on Matt's cock as it swings side to side while Matt runs across a winding road, causing the earth around him to rumble with each step. "Matt--!! Where are we going?!" Blake asks, panicked. "The city, son! Daddy's gonna get even bigger!" Matt says as he runs past one of the many large mansions in this area; each one only reaching up to Matt's shin in height with how much Matt has grown now. "Bigger?! But, why the city?" Blake asks again. "Don't worry, daddy's got a plan. I'm gonna be the biggest thing known to man, and you're gonna help me." Answers matt as he runs towards the city in the distance, leaving giant foot-shaped craters and a trail of thick, giant cum behind him.
