Mike's heart skipped a beat and a shock of erotic pleasure coursed through his entire body when he heard Jimmy call him "son". His long cock twitched and started spewing pre-cum in a steady stream.
Mike had never told anyone that he was sexually attracted to his own father. His dad was a very muscular, handsome man. Mike never knew his mother, but clearly he had inherited most of his physical attributes from her because Mike barely looked anything like his dad. They both had the same facial features, but where they looked sharp and rugged on his dad's thick and muscular body, they looked out of place and plain on Mike's soft and flabby body.
Mike stared in shock and awe at Jimmy as the transformation began. The blond hairs on Jimmy's legs darkened and grew thicker. The dark hair spread up Jimmy's torso, looking exceptionally dark against Jimmy's pale skin.
"Oh fuck, yeah" Jimmy said as he ran his hands through the hair spreading across his tight chest. "I always wanted to have a really hairy body!"
Next, Mike saw Jimmy's feet start expanding, filling out his dad's sandals. Mike's dad had really big feet (size 14) and since Jimmy's feet were just size 10, they increased dramatically in size.
Both Jimmy and Mike were on the short size, both coming in under 6 feet. Mike's dad was just a bit over 6'4" so Jimmy had some growing to do. The socks appeared to be rapidly shrinking, but they were being stretched out over Jimmy's growing feet and his legs were clearly stretching to a new length.
Jimmy quickly grew to become the same height as Mike's dad, but he looked absolutely bizzare. His slender muscles hadn't yet changed, so he looked like someone had stretched him out like he is as made out of putty.
Jimmy grunted loudly as his very skinny frame started to fill in. His entire body slowly expanded outwards, his muscles tensing and bulging as they grew bigger and bigger.
"Oh fuck, Mike" Jimmy said breathlessly, "you didn't tell me this was going to feel so fucking hot!"
After another few moments, Jimmy's body now matched Mike's dad's in almost every way. His muscles were huge and very defined. Jimmy was grinning wildly as he was running his hands across his arms, chest and abs. "These muscles are so amazing, Mike!"
Jimmy turned around and gave Mike a view of his dad's bubble butt, lightly smacking it and rubbing a hand across his cheeks. Mike's dad had played hockey most of his life, so his legs and ass were huge while still being very muscular.
Mike saw that Jimmy's skin seemed to be darkening. Mike's dad had been wearing those sandals at the end of the summer, so his tan was at its darkest. Jimmy's pale skin darkened until it was the same incredible golden colour dad usually sported by the end of a summer. Mike was pleasantly surprised to see that even Jimmy's bathing suit area was dark. Mike's dad must have done a lot of nude sunbathing, something Mike didn't know about his dad.
Next Jimmy's hair shrank into his head, leaving nothing but stubble. At the same time the smooth complextion of Jimmy's face became dar and rough as heavy stubble grew across his face. Mike's dad had lost most of his hair in his twenties, so he always kept his head almost completely shaved. But he made up for it with a very neatly groomed beard that enhanced his handsome features. Jimmy ran his hands along his face and head, his smile remaining as bright and wide as it was before he lost his hair.
"I think your dad's shaved head is really sexy," he said as he gave his head a rough rubbing, "especially that fucking sexy beard he's always got going on."
Jimmy's facial features shifted: his nose flattened out a bit and grew larger, his lips puffed it a bit, his eyes widened and changed from green to crystal blue, and a few wrinkles appeared at the edges of his eyes and his mouth. Jimmy's teeth even grew a big bigger, his canines growing a bit longer and sharper. Mike's dad had always joked that he was part vampire.
Jimmy transformation into Mike's dad was almost complete. The only parts left to change were his cock and balls. "Oh yeah," Jimmy said as he stared at his crotch, "here comes the best part!"
Jimmy's large cock was already hard with excitement. His balls were a pretty average size, but slowly inflated to become much larger. They went from golf balls to tennis balls and stretched out so that they hung heavy and low. Next, Jimmy's cock stretched out from 8 inches hard to a massive 12 inches. It looked very strange at first, as Jimmy's cock was long but a bit on the slim side. But his cock started to thicken until it was as wide around as a soda can.
Even before Mike had seen his dad naked, he knew that his dad had a humongous cock. Dad's hockey buddies called him "The Bulge". Every time dad's friends would hang out at the gym, they would end up getting drunk and picking on his dad for having such a massive cock. They told stories about it swinging around wildly in the locker rooms after every game.
Jimmy grabbed his new massive tool and gave it a few pumps. He closed his eyes and moaned sensually. "It's so fuckin' big," he said quietly in his new voice, the same voice Mike had heard every day for his entire life.
The transformation was now complete. Standing in front of Mike was his hot, muscular, naked dad. His eyes were closed as he enjoyed his massive erection, which he was slowly pumping up and down. Mike felt like he was having an out of body experience. The fact that Mike was currently in Jimmy's muscular body was adding to the strangeness of the situation.
The two of them remained where they were for several minutes, not saying a word. Jimmy kept his eyes shut as one hand slowly jerked his huge tool, while the other roamed across his chest, stomach and sometimes back to his ass. Mike was now jerking his own cock, smearing the copious amounts of pre-cum flowing out of his cock up and down his shaft.
Eventually, Jimmy took in a deep breath and slowly opened his eyes. He looked at Mike, a smile spread across his face.
"Fuck yeah," Jimmy said as he struck a muscular pose, his entire upper body flexed and bulging. "Your dad is so fucking hot, this feels amazing!"
Jimmy continued to take different muscular poses, grunting and moaning in pleasure. His massive cock was flopping around wildly, making loud slapping noises and leaving smears of pre-cum all across his torso.
Mike sat on the edge of the bed jerking his cock, amazed at watching his father act in such a overtly sexual way. Jimmy now looked just like Mike's dad, who had never acted this way in front of Mike before.
Jimmy stopped flexing and grabbed Mike by the hand, pulling him off the bed and up against his naked body. Mike shivered with pleasure as he felt his new body rubbing up against his naked father's body. He could feel the massive organ pressing up against his own cock, hot and throbbing.
Mike was breathing heavily. With each breath, he could smell his father's scent. He smelled like the beach, like sun Tan lotion and sand. He smelled a bit musky, like he had gone for a run and didn't shower. Mike just kept breathing in deeply to take in the scent as much as possible. He rocked his hips back and forth, rubbing his own throbbing erection against his dad's.
"You're moaning like a bitch in heat," Jimmy said sensually, brushing his lips up against Mike's.
"Well, it is your body," Mike said, "you would know how much of a slut I feel like right now."
Jimmy smiled. He reached down with both arms, grabbed Mike by the waist and hoisted him up in the air. Jimmy grabbed Mike by the back of his legs, pulling them forward so that Mike's legs were wrapped around Jimmy's waist.
Mike clasped his legs tight around Jimmy's waist. They were still face to face, but Mike could now feel Jimmy's hard cock pressing up against his hole. Mike rocked back and forth a not only rubbing his cock between Jimmy's pecs but rubbing his boypussy across the head of Jimmy's dick.
Both men moaned from the erotic sensations. Mike was practically gasping from pleasure. Jimmy reached down with one hand and started fingering Mike's hole. Mike gasped as Jimmy easily slid three fingers up inside him.
"I don't know if you figured this out or not," Jimmy said as he probed Mike's hole, "but I was a total fucking slut at camp. Every guy there had a chance to fuck me, so I know just how ready your hole is right now."
Mike had only tried to play with his own ass once, but found it to be painful and unpleasurable. Now that he had Jimmy's body, the feeling of three fat digits probing his insides was the most amazing feeling he had ever experienced.
"The boys at camp all learned pretty quickly that I was a moaner. They had to clamp their hands down over my mouth to keep me from moaning too loudly at night." Jimmy laughed loudly, but Mike only heard his father's laugh.
Mike let out a loud moan as he felt Jimmy push deeper into his ass. "That's why they called me Clamp."
"Not that it mattered," he said, "the camp counselors were all fucking me too, so they would have probably been happy to join in if they heard me."
Mike was unable to speak. Not only was he feeling pleasure like he had never felt before, but he had his legs wrapped around his muscular dad's waist while his fingers were probing his ass. Mike had spent many nights in his bed, fantasizing about his dad coming into his room and taking advantage of him. And now it was all happening, for real.
Jimmy leaned forward, his lips brushing up against his ear. "Wanna know the other reason they called me Clamp?" he whispered.
Mike nodded his head and felt Jimmy push deeper into his ass. Suddenly, Mike felt Jimmy's fingers rub up against something deep inside him that caused him to yell out as waves of pleasure radiated throughout his body.
"Fuck, yeah" Jimmy said loudly as he continued to rub his fingers against Mike's sensitive prostrate. True to Jimmy's nickname, Mike felt the muscles in his ass involuntarily clamp down on Jimmy's fingers ass tightly as possible.
"You're so fucking tight," Jimmy said with a laugh, "I can't wait to fuck you with your dad's massive cock."
Jimmy pulled his fingers out of Mike's ass swiftly, eliciting another moan from Mike's lips.
Jimmy tossed Mike onto the bed like a rag doll. He climbed up onto the bed, lifted Mike's legs over his shoulders and pressed his huge dick up against Mike's ass. He leaned in close to Mike, his crystal blue eyes staring deeply into his own.
"Do you want my cock inside you?" Jimmy asked softly. For a brief moment, Mike felt like it really was his dad asking. He felt the love for his father swell in his heart, so powerfully that he leaned forward and kissed Jimmy passionately.
"Fuck me, daddy" Mike said quietly.
Jimmy plunged his cock into Mike's ass. Mike moaned loudly as he was filled with his father's cock. Jimmy pushed hard until Mike felt his dad's balls slap up against his ass.
Both men remained frozen in place. Mikes whole body was tingling at the sensation of being impaled on his father's dick. Deep in Jimmy's eyes, Mike could see that he was also feeling an equalling incredible sensation of filling his young, muscular self with a massive dick.
Jimmy pulled back his cock until it was almost completely out of Mike's ass, then drove it back in as far as it could go.
Jimmy began to fuck Mike with long, slow thrusts. Mike was seeing stars with each thrust. He his hands into Jimmy's muscular back, pulling him forward as hard as he could. Jimmy was grunting with each thrust. Mike could feel the head of Jimmy's cock flaring as Jimmy tensed and untensed his cock.
After several minutes of fucking, Mike pushed Jimmy to the side and onto his back. Jimmy's dick was still inside Mike's ass, but now Jimmy was on his back and Mike was riding his dad's cock.
Jimmy pushed back, letting Jimmy's cock press deeper into his ass. Just as Mike felt his ass hit Jimmy's crotch, he felt the tip of Jimmy's cock press up against his prostrate. Jimmy and Mike both moaned in pleasure.
Mike looked down at Jimmy. Even though he knew that Jimmy wasn't really his dad, that it was just the magic of the socks, Mike couldn't help but smile as he saw his dad's naked body beneath him. Mike traced his finger along Jimmy's abs, feeling the deep crevices between each of the powerful muscles. He ran his hands up to Jimmy's massive pecs, squeezing them roughly and pinching his nipples, all the while rocking slowly up and down on his cock.
Mike could see the pleasure in his father's face. Mike could tell that Jimmy was really enjoying this. Jimmy's hands were firmly gripped on Mike's bubble butt, massaging the cheeks and spreading them apart to let more of Jimmy's cock into Mike's ass.
Mike felt a warm, fuzzy happiness spread outward from his chest across he entire body as he watched his father's face fill with pleasure. Mike gazed deeply into his father's crystal blue eyes as he bounced up and down on his cock faster and faster. Jimmy grabbed Mike's cock with his father's big, strong hands and started to jerk Mike's cock fast and hard. Mike could feel Jimmy using his powerful thighs to fuck his ass faster and faster.
Jimmy and Mike were both gasping and swearing in pleasure.
"Fuck my hole!"
"Oh shit, your ass feels so amazing."
"Yeah, squeeze my tits. Yeah. Pinch my nipples hard!"
Mike could feel an orgasm building and he could tell from Jimmy's rapidly increasing moans that his own orgasm was nearing.
Mike leaned in, his hands on his father's face, and kissed him passionately. He leaned back just as he felt his orgasm about to blow, looked into his father's eyes and whispered, "cum in my ass...daddy."
Jimmy's eyes grew wide and he roared as he shot his load deep into Mike's ass. Mike could feel his dad's hot load, feeling each shot splatter his insides. Mike was now moaning loadly as he felt his own load shooting out of his cock, splattering against his muscular chest and falling down onto his father's muscular torso.
Mike continued to rock up and down on Jeremey, relishing the orgasmic bliss. Mike was astonished by the sheer size of both of their loads. Mike's cum was pooling on Jeremy's stomach after four or five massive spurts from his cock. Mike could feel his ass filling up with his dad's load, which must have been over ten spurts now.
After a full minute of the best orgasm both of them had ever experienced, Mike collapsed into Jeremy's arms. Both of them were sweating, coated in cum and heaving from the exertion. Mike took long, deep breaths, filling his lungs with his father's scent. A smile was plastered to his face, and he felt a sense of happiness and satisfaction that he had never experienced before.
Mike pushed himself up and pulled himself off his father's cock. It made a loud, sloppy pop as it slipped out of his ass. Mike blushed as he felt his dad's load leaking out of his pussy.
Jeremy laughed and sounded just like Mike's dad. He slapped Mike's ass, grabbed him by the waist and flipped him onto his back. Mike felt the weight of his father pressing down against him like a warm blanket, his still hard cock pressing into his leg.
Jeremy kissed him hard, pressing his tongue deep into Mike's mouth. He pulled back and said,
"That's my boy."
