Months had passed since Izuku's encounter with Katsuki in the locker room, Izuku had moved on since then, training with All Might. All Might promised Izuku that he would pass down his quik as long as Izuku trained so his body could handle it. Izuku wasn't just a fanboy to All Might, he had the biggest crush on him, wanking to the thought of him plowing into him. When All Might's clothes are torn after a battle really turns Izuku on, seeing the giant covered in sweat really gets his gears going. All Might has been training him, getting him stronger by getting him to remove the rubbish from the beach.

All Might turned up early on the morning of the exam to see the progress and finally pass on his power. As he arrived he saw Izuku upon a pile of tires, he then continued to look around to see that he had passed on his expectations with a few minutes to spare. Izuku saw All Might and climbed down the pile of tires, meeting him on the edge of the sand. All Might gave him a speech on how he has done what he expected, then more.
"The only way to pass on my power is... By consuming some of my DNA." All Might was still in his weak form as he said this. Izuku looked at him.
"How am I going to eat some of your DNA?" He asked curiously. All Might started rubbing his crotch through his clothes, Izuku watched as a tent started to appear. All Might's muscles bulged up as his height increased, his chiseled sculpture of a body appeared as his hair stood up and his jaw grew sharp corners whilst he smiled down at the green haired boy. Izuku gulped, wanting All Might's DNA now. All might took off his coat to reveal he was wearing nothing underneath. All might had the biggest cock Izuku had ever seen. His balls looked heavy and hung low with a nice amount of hair on them, his long, fat cock pointed straight towards him as the tip of his foreskin was stretched back a little, showing off the pink head below. All Might had hairy legs and a huge mass of blonde pubes at the base of his dick, the pubes left a trail, leading up over his belly button and continued before dispersing across his large pecs and surrounded his pink nipples.
"The only way for me to give you my power is if you drink my sperm..." All Might said, knowing it wasn't the only way but he knew Izuku would suck him off and he was incredibly horny. Izuku was shocked at how big the dick was infront of him, the hero that he worshiped was right in front of him, offering him his cock. Izuku's mouth started watering as he wanted to get All Might's spunk in his mouth. All Might's hand came down and started to rub his length, his balls bouncing as he did so.
"Little help here?" All Might said, inviting Izuku to touch his naked body. Izuku's hands came forward and started stroking the hairy nut sack infront of him, rubbing over the wiry hairs that rested there. All Might's balls were huge, just one of them hardly his into Izuku's small hand. Izuku watched as they bounced in his hands. He was mesmerized by the head of the cock, showing the pink head before hiding behind All Might's foreskin. Izuke's hands caressed the low hanging, hairy balls whilst his mouth watered. He could see All Might was enjoying his hands exploring his body so he took it a step further, he moved forward and leaned under All Might, taking the large orbs into his mouth. He sucked and licked the huge hairy balls. All Might started moaning as he started playing with his own nipples with one hand and still wanking with the other, whilst Izuku sucked on his balls.
"Help me with this." All Might said, slowing his pace on his dick to make room for Izuku. Izuku's hand came up and held onto the huge cock above him, still latched onto the heroes nuts. Izuku started wanking All Might fast, the sounds of All Might's moans and foreskin filled Izuku's ears. He started humming whilst his mouth was filled, tasting all of the swear All Might managed to gather whilst on his way to the beach.
"Use your other hand and reach behind me." All Might demanded. Izuku moved his left hand off All Might's hips and reached under his nuts that he was still attached to and started groping the two hard mounds behind. He explored both ass cheeks before parting them and digging his finger through the trail of hair that hid All Might's ass hole, pressing his fingers against the tight rectum. Eventually he pressed hard enough to bury his finger in the hole.
"Yeah... Now suck this young Midoriya." Izuku dropped the now slick balls out his mouth and stuck his tongue out, licking the exposed head of All Might's dick. He then opened his mouth more and placed the cock in there, he sucked the tip for a few minutes whilst wanking him off and fingering him at the same time. All Might started pushing Izuku down, burying more of his dick into the green haired teens mouth. His large hands covered the back of Izuku's head until he started to stretch his mouth. Izuku could only go about three quarters of the way down before coming back up. He took his mouth off the cock.
"You need to force me down, I want to taste all of it!" He said enthusiastically. Hearing this turned all might on more. Izuku put his mouth back over the dick and started lowering himself more and more until he could do it any more. All Might could feel his balls stiring as he placed his hands back on Izuku's head.
"Here I go kid!" He said as he started pushing his future student down his humongous cock. There was only soo far he could push him down before he got the idea to start thrusting. He started moving his hips backwards and forwards, making his balls swing as he started, eventually he picked up his pace. Now, the teens nose was buried in All Might's wiry blonde pubes as the large nuts slapped against his chin. Izuku was gagging as the head of the dick buried its way down his throat.
"Your'e soo fucking good at this!" All Might said, Izuku could feel the balls getting tighter as they slapped his chin. Izuku started moving his finger that was in All Might's ass faster, adding another finger to the mix, he also started stroking All Might's balls with there being no room on his dick to stroke. All Might was aggressively thrusting into the boys mouth.
"Oh Fuck! Here it comes!" All Might screamed as his balls tightened for the last time, unleashing an ocean of cum in Izuku's mouth. Izuku swallowed as much as he could before he had to come up for air, spilling some of All Might's seed onto the sand below. As he took his head off the massive cock, All Might was still cumming. Sending blasts of hot jizz onto Izuku's face, covering it in a salty blanket. Izuku reached up and put as much as he could into his mouth, trying to get more of All Might's power, he then leaned over to clean the tip of All Might's dick, giving it one last stroke in the process. All might looked down to see that Izuku had came in his pants whilst blowing him, he took out a small cloth from his coat pocket and wiped the excess cum off Izuku's face. He then reached into his other pocket and pulled out a new pair of pants, knowing that Izuku would cum in his pants. He then looked at the clock, seeing there was only an hour left before the exam. All Might covered himself with his coat again before returning to his weak state.
