Steven stopped at the rear entrance his dad's van. As quietly as he could, he turned the handle of the door until it was open enough for him to fit through it. Stevens silently stepped inside to find his dad splayed out on the van floor, asleep. He shut the door behind him, and went to turn on the light. As he pressed the button to turn on the light Greg snored incredibly loud, scaring Steven into almost falling down. Once he recovered and made sure his dad was still asleep, Steven got on his knees beside his dad and began his mission.

First, he untied his dad's sweatpants, to make sure they would come off easily. As quietly, and stealthily as possible, Steven got up and stood over his dad, with his feet placed on either side of him. He reached down and grabbed the waistband of his sweatpants with a hand one each side and slowly pulled them down, and eventually off of his dad. When Steven sat back down beside his dad, he noticed that there was a huge bulge in his boxers, but his dad's penis hadn't even gotten big yet! Steven had to make sure that he didn't have a bulge that big too, so he unbuttoned, unzipped, and slid his jeans down his legs and kicked them off. He looked down at his own boxers, and found only a small bump in the front of his underwear, it was tiny compared to his dad's bulging package. But now Steven wanted to know how big it really was. Steven grabbed the waistband of his dad's gray boxers and pulled them down slowly, first revealing his dad's huge amount of pubic hair compared to his own, and as he continued to pull, Steven saw how thick his dad's manhood was at the base, and it continued down the length of it. "It must be like seven inches around!" Steven thought. Finally he revealed the tip of his dad's penis. "That looks twice the size of mine when it's small!" Steven thought to himself. He also noticed that it was a bit different from his, missing the bit of skin that covered his own tip. Steven finished pulling his dad's boxers off and threw them over with his dad's and his own pants. Steven sat back down by his dad's side, and thought to himself "It's so big now, but how big does it get when it grows?" So he made that Phase 2 of his mission.

Steven reached forward and grabbed his dad's thick, floppy penis, and started to stroke it up and down hoping to make it grow. After a minute or so of stroking, not much was changing, and stroking his dad while he was soft was kinda hard to do. Steven remembered that he saw a guy in a video licking and putting another guy's penis in his mouth. "Plan B, Here goes nothing!" Steven said to himself quietly. He held his dad's base, leaned over and licked the underside of his dad's tip, then again, and again, then Steven began to circle his tongue around the tip, and in no time Greg's penis grew to it's full size. "Oh my god, it gets that much bigger, wow!" Steven slipped off his own boxers, and now that his dad was at full size, and Steven had gotten there a long time ago, Steven compared their size. He stood over his dad once again, and held his own boyhood next to his dad's sizeable manhood. "Wow, almost 3 inches bigger than mine!" Steven thought. "Mission accomplished, older people do have bigger penises than me!" He confirmed his hypothesis happily. "Hmm, but I probably shouldn't just leave dad like this…" Steven got back down on his knees and leaned over. He took as much of his dad's penis into his mouth as he could, around half of it at first, then he came back up, and went back down, about three quarters of the way to the base, he came up again, took a deep breath, and finally he slammed himself down onto his dad's immense member, nearly choking himself by filling his throat with his father. Greg stirred in his sleep, but Steven was too busy to notice.

Nearly 5 minutes had passed while Steven was masterfully sucking his father, but that thing that happened to Steven where the stuff came out just wouldn't happen. "Jeez dad, whats taking so long?" Steven wanted to ask him. He wondered if there was a faster way to get his dad to spray his stuff. "Hmm…" he thought as he continued to suck "I've tried my mouth, and the only other hole I have is my…" Steven lifted his head off of his dad's huge penis and looked at it, it almost looked bigger than before, but he couldn't be sure. Steven stood over his father once again, and lowered himself slowly. He made sure his dad's penis was sticking straight up, and it stayed there, then Steven spread apart his chubby ass and lined himself up. "Here goes Plan C!" he whispered before he dropped himself onto his dad's manhood. Unable to raise himself back up, Steven impaled himself with the entirety of Greg's penis. He screamed in pain, much to the surprise of Greg, just waking up to see his Son, half naked on top of him. "STEVEN! WHAT ARE YOU- AHHHH!" before he could finish his sentence he blew his seed into his son's no longer virgin asshole.

"Ooooh jeez Steven, what are you doing with my cock in your ass?" He asked, with a strong undertone of pleasure in his voice. "Umm… by cock, do you mean your penis?" Steven asked, wincing at the pain he still felt in his ass. "Yea, cock, dick, penis, they all mean the same thing." Greg said. "Oh, those sound way cooler than plain old 'penis.''" Steven replied. "So, you wanna answer my question now kiddo?" Greg inquired again. "Oh right, umm well you see…" Steven started "I saw these videos online, and the guys had way bigger umm, dicks than I did. The videos made me all tingly so I played with my dick until it sprayed this stuff that tasted sweet. But then I wondered if anyone else had a bigger dick than me, so I umm… Came to see yours." Steven said, blushing a deep red by the end. "Oh jees kiddo, you could have just asked and I could have explained to you that it gets bigger as you age." Greg told him. "Ooooh thats how it works! That makes sense, thanks dad!" Steven said smiling. "So, after you saw that mine was bigger, what led you to take my cock up your ass son?" Greg asked his son. "Oh well umm, I just thought that it would be mean to make your dick all hard and then just leave it like that, so I wanted to make it go small again like mine did after it sprayed the stuff." Steven explained to his dad. Greg laughed "Steven, it will go back to normal on it's own eventually!" Steven looked embarrassed. "Oh…" he said, looking down at the ground. "Well it looks like you've got a little something to take care of yourself still." Greg said pointing at Steven's still hard cock. "Oh yeah, umm-" Steven started. "Here, lets try this." Greg said before reaching out and grabbing Steven's hard cock. "DAAAD!" Steven yelled as he lost control of his body and leaned back, leaving his dick to spray his seed all over his dad's face and shirt. "Hehe…" Steven said panting. "I guess you were right on the edge, eh son?" His dad joked with him. "Yeah I guess so, ha. Sorry about getting my stuff all over you dad." Steven said, apologizing. "Oh you mean your cum? Don't worry Steven, It'll wash off just fine." Greg replied, and they shared a laugh. "So anyways, would you mind… getting off my dick now?" Greg motioned towards his softening dick still inside of his son. "Oh, right sure, yea!" Steven said as he slowly lifted himself up off his dad's thick cock. There was an audible *pop* sound when Greg fully slid out of his son, followed by a stream of cum leaking out of Steven's freshly fucked hole. "Oh, right forgot about that." Greg said. "Don't worry Dad, I liked mine, I'm sure yours is good too!" Steven said as he leaned back over and licked his dad's cum off his shrinking dick, his balls and the rest of his crotch. "Oooh jeez Steven you're better than your mother at that." Greg said without thinking. "Mom did this with you?" Steven asked. "Yeah," Greg replied "But you're more of a natural at it." he said, smiling at his son as he ruffled his hair. "Lets go get washed up kiddo." Greg said, opening up the van's door. He stripped himself of his shirt and ran into the ocean. "Hurry up, the water is great!" he called back. "Oh dad." Steven said to himself as he lifted his shirt over his head, revealing his smooth stomach, and threw his shirt into the van. "Coming!" he yelled back to his waiting father.
