Katsuki was frozen in shock at what his boyfriend just asked him.
"K-Kacchan? Do you- not want me to?" Izuku asked innocently.
"Um... I mean- fuck..." Katsuki couldn't say what he meant.
"Oh hey it's okay, just forget about it! It's no problem!" Izuku giggled nervously as he waved his hands in front of Katsuki's face, but for a moment he was a bit let down. He had thought about doing something like this for awhile, but he was worried that Katsuki wouldn't allow him to, or for a better way of putting it, he was worried that Katsuki wouldn't submit to him. Izuku laid down and closed his eyes, embarrassed for even asking to please Katsuki. The blonde laid next to him on his side to face him, playing with his hair.
"Izuku... I want you to..." He said softly, making the greenette's eyes shoot open.
"Woah are you sure? If you're not ready I don't have to-"
"Didn't we just go through this with you, you fucking nerd? Yes, I'm sure!" Katsuki chuckled. "I was just surprised at first when you asked. I didn't fucking think you would wanna do something like that..." Katsuki growled as he turned onto his back to look up at the lights.
"If it's with you, then of course I wanna do it!" Izuku whined softly as he turned his head towards Katsuki, with the latter doing the same to Izuku. Katsuki turned his whole body to the side to face his boyfriend, cupping his cheek lovingly. He moved his body closer and leaned forward to kiss his boyfriend, just once.
"Well any day now you fuck." Katsuki growled teasingly, making Izuku giggle as he sat up and pushed the blonde onto his back.
The greenette straddled his boyfriend with both hands on his cheeks, kissing him lovingly and passionately as Katsuki put his hands on Izuku's bare thighs. The blonde squeezed the greenette's thighs as they kissed with their tongues, Izuku threading his fingers through Katsuki's hair lovingly. Izuku had close to no idea where to start here, but he took notes from Katsuki and went down to his neck. He trailed kisses down, lightly sucking here and there to try and find his sweet spot.
"Do something unique, Deku." Katsuki smirked. Izuku quickly searched his brain for an answer as he kissed Katsuki's neck, and then quickly found an answer. Katsuki always pushes himself in training and never lets pain bother him, maybe he likes it. He decided to start out by licking his neck gently, which made Katsuki raise his eyebrow. Then Izuku's tongue hit a spot that made Katsuki gasp, meaning he found his sweet spot. Izuku smiled and went to suck on it first, then he bit down- hard. Katsuki's eyes widened as he breathed a little heavier, confused at the new sensation. Izuku bit down a little harder, making Katsuki hiss at the pain, but not protest it.
"Do you- like pain, Kacchan?" Izuku teased.
"Shut the fuck up and keep going." Katsuki growled. He was seriously screwed if his boyfriend could figure out his weaknesses. Katsuki liked the idea of pleasure, but sometimes it overwhelmed him and he would get scared of it. But he couldn't risk getting scared now, as this was such an intimate moment with his boy.
Izuku then moved down further towards Katsuki's groin, starting to hesitate. He was really nervous to do this kind of thing with a guy, and he wanted to do it right. Especially with that guy being Katsuki, he had to make sure his boyfriend felt an intense amount of pleasure like he just did moments ago. He rubbed his hand on Katsuki's package, feeling everything he had to offer inside. Katsuki was starting to sink into the pillows he was laying on, feeling tiny jolts of pleasure here and there. He had touched himself before, but it's so different when someone else does it. It almost didn't even matter that he had the experience of touching himself before, considering he was still so incredibly sensitive to Izuku's touch. Izuku unbuttoned and unzipped his boyfriend's black jeans, sliding them off of his legs with a bit of help from Katsuki. He threw his jeans outside of the fort as Katsuki sat up a bit and took off his shirt, throwing it past Izuku outside of the fort as well. Izuku just realized, Katsuki was about to be totally naked for him.
Izuku got low near his groin and rubbed his hands softly along his inner thighs, guiding his legs to spread open but not by too much. He suddenly flushed a deep shade of red as he suddenly became conscious of what he was doing and got embarrassed, but pushed through for his boy. He rubbed his hand over Katsuki's hardened member, as big as it was. He softly teased his balls by brushing his fingers lightly over his boxers. Katsuki huffed as it was almost ticklish, but sexually. Izuku decided it was time, as he slipped his fingers into the waistband of his boyfriend's boxers and slipped them down off of Katsuki's legs and off to the side. His large member laid before him beautifully. Izuku almost wanted to cry at the full sight of his gorgeous boyfriend. Izuku looked up at Katsuki with wonder in his eyes as the former smiled proudly, reaching his hand into the greenette's hair.
"Do you like it?" Katsuki asked while smirking devilishly. Izuku bit his lip and nodded silently, looking back down at Katsuki's manhood. He reached forward and wrapped his scarred hand around his boyfriend's shaft, squeezing it semi-tightly but endearingly. It was so warm in Izuku's grip, Katsuki gasped softly at the feeling. He kept his hand on Izuku's head, ruffling his hair gently. The greenette started to lick up Katsuki's shaft, making the blonde breathe heavier with pleasure. He wanted to watch his boyfriend do his thing, so he grabbed a small pillow with his other hand and stuck it behind his head to prop himself up a bit. Once Izuku reached the sweet spot just below the tip, he gently sucked on it which made Katsuki moan proudly. Izuku had a lot of saliva ready in his mouth, so he finally took in Katsuki's member. Katsuki gasped and widened his eyes at the feeling of his dick inside Izuku's mouth, the warmth surrounding him. What surprised him the most is how good Izuku was at sucking up and down, dancing his tongue around the tip and giving love to his sweet spot as he bobbed up.
Katsuki was panting heavily as he started to grip Izuku's hair tightly in his fingers. He started to close his eyes partially as the pleasure overtook him. Izuku moved his other hand to his boyfriend's hip, scratching his nails downward. Katsuki hissed as he throbbed in Izuku's mouth, loving the pain. Izuku sped up his bobbing, his jaw a little tired but he wasn't about to stop. He used his hand to pump up and down at the same time, making Katsuki grip the pillows next to him with his free hand. He curled forward a little bit away from the pillow he was leaning on as the pressure kept building inside of his member. He moaned loudly as he felt himself nearing his release.
"Izuku- out- I'm gonna- I'm gonna cum-" Katsuki huffed out as Izuku quickly popped his boyfriend's member out of his mouth. Katsuki immediately released his load all over Izuku's face and in his hair, with the greenette just squinting to prevent anything from getting in his eyes. Katsuki's eyes widened at the sight of his love all over Izuku, instantly feeling terrible.
"K-Kacchan... a lot came out, huh?" Izuku chuckled a bit while wiping some off of his eyebrow.
"Oh my god, towel- we need a towel!" Katsuki yelled as he was just about to sit up. Izuku bent down a bit and licked up the tiny bit of cum still leaking out from Katsuki's member, making the latter flinch as the feeling was almost too much to handle.
"You're right- that is bitter..." Izuku giggled as he kept his left eye closed. Katsuki chuckled as he grabbed his boxers and scooted out of the fort. He led Izuku to his bathroom where he wet a wash cloth and helped him clean up his face.
"I'm so fucking sorry, I didn't mean to get it all over your face!" Katsuki hissed.
"It's alright, really! Did you like it?" Izuku giggled as the wash cloth brushed over his left cheek.
"Like it? Are you kidding? It was fucking amazing! I didn't realize you'd be that good at it." Katsuki praised his boy.
"I can't believe we just did that!" Izuku giggled happily as Katsuki wet the wash cloth again and brushed it over the little parts of Izuku's hair that still had cum in it.
"Heh, yea me neither." Katsuki gave Izuku a small loving kiss. "I love you so much, Izuku."
"I love you more, Katsuki."

"Oh my god?"
"So I take it the pillow fort was a success?"
The two boys sat nervously across from their best friends in a booth, blushing deep shades of red as they told them the news.
"Wow, Izuku. Hearing that you went that far- it's just so-" Eijiro hesitated.
"I know what you mean!" Izuku giggled.
"That's so manly!" Eijiro whimpered as tears started welling in his eyes.
"Aren't you being a little dramatic, Eijiro?" Shoto added in monotone.
"Thanks guys for helping with that the other day, I owe you..." Katsuki grumbled.
"Did Katsuki just thank us?" Eijiro teased, making Shoto smile softly at the joke.
"ALRIGHT SHUT UP FUCK YOU TOO, SHITTY HAIR!"
"Aaand there's angry Katsuki!" Eijiro teased.
"YOU WANNA FIGHT? FIGHT ME THEN!"
Izuku started laughing cutely at the two boys, making even Shoto crack a small chuckle. As the boys finished up their barbecue lunch, they started to listen to the last of their best friends' stories of summer. The boyfriends had the best summer vacation of their lives this year and they couldn't wait to have more summers together.
