Chapter Text
Yu had never felt so much dread and anxiety fill his body. He laid in his futon, befuddled as he mulled over his current situation. His entire day had been relaxing and he had woken up feeling as if nothing could drag him down, all being forgotten because of the painful, throbbing, excruciating erection in his sweatpants.
Yu had an agreement with Yosuke after the school had ended to meet him on the roof away from the other members of class to talk privately; yet, not much talking had taken place in their escape. One thing lead to another and the pair had started kissing instead, a drawn out make out that made Yu shake with excitement. He cringed as he remember, his erection throbbing in time with his heartbeat.
The troublesome arousal started from this kiss, and had returned again and again after to the great discomfort of Yu. How he'd wished it would just go away and stay gone! It seemed as if it only went away when convenient, like having dinner with Nanako, only to stir up again before his bath and now before he could slip away into sleep.
Frankly, Yu was just over this feeling but how could he rid himself of it?
He had only experienced this a few times, his first one was when his friends from the city gave him a gay manga as a joke. Even if it was a practical joke, he couldn't tear his eyes away from the buff, hairy men as they kissed and had sex. He spent the whole night with the manga and a irritating arousal between his legs.
He sat up in his futon, moving the blankets away. Yu had to fix this, he would have to find a way. He hunched over on all four limbs, trying to think how. It's not like he could go look for more gay porn to figure out what exactly to do about it.
He groaned, collapsing down on his futon and then immediately regretted it as his erection hit the mattress. He pushed his knees up, beginning to stand again when he stopped. Yu tried the motion again, realizing the friction felt somewhat nice. He did it again, rubbing the boner against the mattress.
"Hmm," He whined to himself, finally finding a bit of relief. This must be a normal way to do it, right? Maybe he would have to go find some gay manga to figure out other ways.
Yu kept up the humping motion, starting to pant as his heartbeat sped up. This was good, the best feeling he had ever felt. He could feel himself slipping away, finding himself addicted to the growing buzz in his groin.
The door to Yu's room creaked open, the light from the hallway flooding in to illuminate his sins.
Yu yelped, quickly turning himself over and pulling the blanket up to cover his erection. Dojima stood in the narrow crack of the door. He quickly grabbed his pillow and hid his crotch away, his shaking hands grabbing the cushion tightly.
"What do you think you're doing kid?" Dojima asked, his gruff voice echoing through the room as the older man crossed his arms.
"U-Uncle, I'm sorry! I didn't mean for you to see that!" Yu's voice trembled and he feared what ever punishment Dojima would give him for the act.
"Jeez, just came up here to make sure you wouldn't stay up all night. I have to work all day, can't you have some decency in my house and at least lock the door? Or do it in the bathroom, at least." The detective shook his head, feeling the need for sleep or a cold beer reeling through him.
"I-I'm sorry, uncle, I didn't know how long it would take, I've never..." His voice trembled, his hands pushing the pillow down and wincing as it brushed his erection.
"Hm, what did you just say?"
"Um, I've never... Um, I haven't ever." The teen floundered as he attempted to find a polite way to explain himself.
"Wait... Don't tell me you've never jacked off before? How old are you again?"
"16?"
Dojima let out a fully belly laughing, bending over with his hands on his knees as he roared with laughter. He wiped away a tear and let out a 'whew'. "Oh man, that's a good one."
Dojima chuckled to himself, but Yu didn't laugh, just blushing and trying to hide away from the older man. He realized the teen was serious, and cleared his throat.
"You're serious? A casanova like you should have been with plenty of girls, I was with tons when I was your age, why haven't you done it sooner?"
"I just," Yu swallowed and he formulated his thought. "I never found the girls in my class very attractive."
"Hm, really..." Dojima rubbed his chin in thought, scratching at his stubble. "Then, what's got you so worked up now?"
"After school today... Well, Yosuke and I kissed before he had to go to his part time job."
The detective hummed, stepping in the room and shutting the door behind him so that their conversation wouldn't wake Nanako. "That Hanamura kid. So what, you two kissed and split? No experimenting at all?"
"We ran out of time, he had to get to Junes. A-And it's not like we're gay!"
Dojima chuckled again. "What, making out with your best friend and popping a boner isn't gay? No need to be ashamed of it kid, that's normal."
Yu felt his face heat up with a blush again, his blood cycling between his cheeks and his still throbbing erection.
"Well, what are you gonna do about that thing?"
"Umm..." Yu shifted in his kneeled position, feeling himself rubbing against the pillow. "I don't know, I don't know how."
"Why don't I show you, hm? Make you feel good for tonight?"
Yu jolted back, falling onto his butt and dropping the pillow. "T-That wouldn't be right! I'm not gay, and you're my uncle!"
"It's not gay, it's normal to teach you about these things. That's what I'm here for, to teach you things." Dojima stepped forward to the middle of the room, Yu could see now the beginning of an erection forming in his uncle's pants. "Come here, I'll teach you how to do it. I know those blue balls you've been dealing with have to be painful if you've been feeling this way since the school day ended."
That must be why his erection felt more painful as time went on. Yu mulled it over before standing stepping closer to Dojima and cringing at the way his erection rubbed his sweatpants. He stopped about a foot in front of him, feeling awkward and nervous.
"Alright, get it out."
With a trembling hand, Yu pulled the waist band of his boxers and sweatpants away from his body and down, revealing his swollen member. Dojima started laughing again as he looked down at the teen.
"Wow, that thing is small! Obviously you didn't get much of my family's genetics. I bet if I..." Dojima reached out wrapping his hands around Yu's penis, his hand fully encasing most of it while just part of the head poked out. "How big is it, huh? 3 inches?"
"3 and a half." Yu lied him, his voice trembling again as he felt his uncle's warm hand ease the ache within him. Really, it was only around 3 inches and a quarter, and that was being generous. Unfortunately, he pulled his hand away before the feeling could fully melt away the discomfort present in his pelvis.
"That's almost cute. Won't be much of a top though... Anyways, you got lotion or anything in here?"
Yu looked around for a moment, spotting a bottle and quickly grabbing it. He brought it over to Dojima.
"Good, put some on your hand."
The teen pumped some out, placing the bottle down on the low table next to them and waiting for the next instruction.
"Lube would probably be better for this, but lotion can work in a pinch. Water is no good, there's too much friction. Now, wrap your hand around the base."
Yu did as he was told, hissing under his breath as he felt the cold lotion seep into the thin skin.
"Move it up and down, start slow."
Dojima kept his eyes focus as he watched, but Yu, in his ignorance, merely glided the palm of his hand on the underside of his penis, rather than gripping and pumping.
"No, no." Yu stopped, looking up at his uncle for clarification. "Here, it'll just be easier if I show you what I mean." Dojima trailed his hands down to his belt, pulling it through the loops and undoing the zipper. He sighed as pressure was relieved on his erection, fishing it out from his boxers.
The teen almost gasped at the size, his eyes as wide as dinner plates.
"Don't stand there gaping like a fish," Dojima chastised, getting a handful of the lotion and spreading it up and down his length. "Now, watch and pay attention."
Yu looked on as he watched his uncle's hand grab the base and start thrusting his hand up and down at a slow drawn out pace.
"See? Like this. Follow what I'm doing."
The younger man copied his movements, slowly moving his fist up and down.
"You can focus on the head too, your foreskin moving up and down should feel really, really good."
Yu abandoned copying him and ran his fingers over the head, his hips bucking as a jolt of pleasure ran up his spine. He whined as a finger ran over his frenulum, quickly covering his mouth with his free hand as the embarrassing noise escaped him.
Dojima chuckled again, slowing his own masturbation down. "Don't be embarrassed, it's normal to make noise. Your partner will like it if you're reactive, then they'll know if they're doing something you like. Here, give me that hand."
He reached up and grabbed his wrist, moving his other hand from his mouth to Dojima's penis.
"U-Uncle?!"
"Shh, not too loud." He checked behind him, listening out to the hallway to make sure Nanako had not woken up. "Try to keep the noises quiet. And keep your hand wrapped around me. Your body will learn its okay to feel aroused with you feel another man's dick, that its okay to moan when you feel it throb in your hand. Now keep going."
Yu, despite feeling embarrassment running through him, resumed his slow thrusting. Dojima rested his now free hands on the teen's waist and felt Yu shiver as pleasure took over once again.
The feeling was starting to feel overwhelming, panting and quietly whining as he bucked his into his hand and began picking up the pace. He could feel mind numbing heat collecting in him, settling down at the bottom of his pelvis.
Yu could feel his balls tightening and suddenly started to feel more pleasure compound into him.
"W-Wait, uncle, something feels wrong." The teen pulled his hand off of his penis, only for Dojima to grab his hand and wrap it around again, overpowering him to let the feeling build in him again. "Wait!"
"Shh, it's okay. Keep going." Dojima continued moving Yu's hand up and down, bringing his other large hand down to grab Yu's balls and rub circles in them with his thumb.
Yu whimpered, everything becoming overwhelming. He could feel Dojima's erection twitch in his hand, his own erection throbbing twice as fast as his heart beat, his balls feeling tighter and tighter.
"Something's wrong! Something's gonna happen-"
"Yes, that's it, keep going." Dojima stepped forward, closer, almost close enough for his penis to touch the head of Yu's. "You're doing good, you're doing it right."
Yu whined again, feeling tears come to his eyes as his whole body shook and thrusted into his and Dojima's hand.
Suddenly, the feeling burst inside of him and something erupted from him. He bit his lip and whined, high and loud as his hips bucked and moved under Dojima's onslaught and electricity shot up his spine, jets of pleasure shooting from his penis. Yu gasped and shook as he started to come down from his high, resting his forehead on his uncle's shoulder and panted.
"There you go, see, not so hard, right?"
Yu started to catch his breathe and stood straight again, looking down at Dojima's torso and gasping at the mess there.
"Oh, uncle! I'm so sorry, I didn't mean to ruin your uniform." The teen had forgotten that part from the manga he read and cringed as he realized the shirt would probably stain.
Dojima chuckled and shook his head. "I knew if I was gonna teach you to cum I'd probably end up with some on me."
The older man ran his hands over his shirt, removing some of the excess lotion and began to tuck himself back into his pants.
"Um, uncle, you didn't finish?"
"Don't worry about it. I'm about to take a bath anyways, I'll finish up in there." Dojima looked up and down at his nephew, nearly salivating as his watched Yu's erection shrink after its long overdue orgasm.
"Now, get to bed. You have school in the morning."
Yu nodded, wishing his uncle goodnight and going back to his futon.
