My Stepbrother Treated My Insomnia with His Mouth

All characters in this story are 19 years or older. This fictional story is meant for adults only.

Me, Robin, and my stepbrother Isaac had been living together for a few years now. Our parents got together three years ago. At first, we didn’t really talk to each other. We both kept to ourselves—and our rooms—but eventually we started having small talks with each other. From tutoring (he was a year older than me, so he remembered the material from school enough to help me) to playing games.

I grew up as an only child, but I figure that having a biological brother probably wouldn’t be much different.

I just finished high school. I’m planning on going to the same college that he’s going to so that I have someone I know in the big city to help me, but also to help with the loneliness. I’m really glad that guy is in my life.

Something that he can’t help me much with is my insomnia. It’s 4 a.m., and I’m rolling in my sheets like a pig in mud. My eye bags look like someone took charcoal and drew them on. This issue started a few years ago when our father left us for another woman. I never told this to anyone, but I blamed myself for him leaving. I thought that if I was better, he would have had the perfect family and would have stayed. Instead, he went to love another son & wife.

My mother got really depressed, and the guilt and the self-blame spiraled into my inability to fall asleep. I eventually grew up and stopped blaming myself (at least consciously). My mum found my stepdad and happiness, but the insomnia stayed.

I went to countless doctors—therapists, family doctors, psychiatrists, neurologists, sleep specialists… I lost count. My mom had to spend so much money so that I could rest properly for once, but even that was for nothing. The guilt from spending her hard earned money on me made for no results made it worse.

I don’t know what’s up with me. Every time I get under the blankets, I close my eyes, stop thinking, and yet… sleep refuses to come. If I do fall asleep, it’s barely two hours.

I’m so tired. It’s so hard to focus on anything when all you want to do is sleep. It’s the reason my grades were so shit. When Isaac would tutor me, sometimes I’d fall asleep mid-lecture. He never got mad at me though, because he knew what it’s like, even if thankfully he never had to suffer from what I do. His voice was just so deep and smooth, and being around him felt safe in a weird way. Maybe it’s because of his older age of one year and bigger muscular body that my brain figured it’s a safe spot to rest. Funny.

Either way, I look at the digital clock on the nightstand where my Xanax pills are. 4:05. I sighed. I knew that everyone is probably asleep by now, but would it hurt to try to spend time with him in case he’s awake?

I pulled the covers off me. The light of the full moon illuminated my gray T-shirt and black boxers. I stretched and yawned, like I just woke up, even though I never fell asleep, and got up.

I gently opened the door of my room and tiptoed my way to my brother’s room. I lifted my hand to knock, but I figured that’s too loud, so I just pulled the door handle down as quietly as possible.

To my surprise, I was met with his eyes on me, his face illuminated by the light of his laptop. “Hey,” I said, suddenly realizing that I don’t know what to say to him.

“Hey lil bro,” he said, his voice as deep as ever. “Couldn’t fall asleep?”

“Yes, Sherlock.”

He chuckled. “Come in.”

I didn’t want to bother him, but I really didn’t want to be alone with my thoughts. I was already here anyway, so I pushed the door open, closed it behind me, and walked over to him.

He pulled the covers up for me, and I slid under the blankets. I could feel his body heat, but we didn’t touched. The light from his computer blinded me for a split second. “Shit, it’s so bright,” I complained.

He pressed a few times on the brightness button, making it more dim for my sensitive ass.

“Thank you. You’re such a gentleman, you know that?”

“Yeah, I know,” he says. As my eyes adjusted to the light, I realized that he was watching a movie. “So… the pills still aren’t helping?” he asked about a minute later.

“No,” I said, my voice sounding as tired as my eyes looked. I sighed. “I’m so tired, man.” I didn’t want to complain. I hated complaining. I know I hated it when people did it to me, but that’s probably because of how exhausted I am all of the time. I’d love to be able to lend an ear.

“I know you are,” he said as a matter of fact. “When did this all start again?”

I didn’t want to talk about this, but I was too exhausted to care. “After my father left us.”

“Oh… do you think that…” he started, but didn’t want to finish the sentence do you have daddy issues?

“At first, probably yeah,” I replied, not giving him much information to work with.

“Is it… because you miss him?”

I frowned and looked at him. “What? Fuck no,” I said, annoyed, but then I realized that he knows nothing about my biological father. “It’s… fuck, sorry… no. I don’t miss the asshole. I blamed myself for him leaving for the longest time. I… wanted us to be a family. But he was a fucking mess. It just took me a long time to see that. It’s… I can’t even explain it,” I said, trying to gather my thoughts to the best of my ability.

“You… blamed yourself because he left? Why?”

“I… don’t know. I was a kid. I was stupid.” I shrugged, trying to pay attention to the movie. “I’ve never told anyone this actually.”

“Really?”

“Yeah. Really. Not even the doctors I’ve been to.”

“…Why?” he hesitated, then asked.

“Because it’s stupid. It doesn’t matter…” I said as two of the characters on the movie were getting laid. They didn’t hide from showing us her tits. “It’s embarrassing to talk about it,” I said, as my dick twitched in my underwear. Thankfully the covers did well to hide it.

“It’s not stupid and it does matter. You matter,” he said. “I had no idea you went through that. I’m glad you told me.”

“Well, you’re my brother. I trust you,” I said. I couldn’t hold it anymore. I leaned on his shoulder. It was physically hard, but also soft at the same time. “You make the perfect pillow.”

He wrapped his arm around me. “I’ve been told.”

“Oh…?”

“Yeah. You’re welcome.”

“…That doesn’t mean that I’ll be able to fall asleep though.” I kept looking at the screen, my dick still hard from how the girl was moaning even if no penetration was shown. “Shit. It’s been a while since I did that too.”

“What, getting laid?”

“Yeah,” I admitted.

“You’re having trouble scoring? You’re quite handsome.”

I smiled. “Thanks. It’s not that. I just… don’t have the energy to do it. You know, you have to go out and find someone. Partying. Dating apps. All of that takes… effort.”

“But… you’re not like… too tired to do it, right?”

“I mean, if there was someone like… right here that went ahead for it, then yeah. As long as I don’t have to go out of my way to find someone.”

“Oh, I see,” he said, his hand squeezing my arm.

“Yeah. I wish I could do it even if it’s just for one night. You know, just to take the edge off… take my mind off some things for a while…”

“Some things?” he asked.

“Yeah. Like how I… I can’t do anything like this…”

He didn’t respond for a few seconds, like he was thinking. Then he replied, “Okay,” and moved his hand from my arm. I looked at him because of the sudden pull of comfort, and he slid his hand under the blankets, reaching for my dick.

The sex scene on the movie was over, so my dick was now half hard.

“What the fuck?!” I yelled a bit louder than intended. “What are you doing…”

“I…” he said, still holding my dick. “I thought you asked me to…”

“Wha… fuck…” I said, going back to looking at the movie. I didn’t want to make a scene or make things weird between us, so I decided not to react as bad. “I didn’t ask you to give me a handjob or something, you weirdo!” I whispered, but I didn’t move to remove his hand.

“But… you’re hard as fuck.”

“Yeah, from the movie! Not because I was initiating… Fuck, you’re my brother, Isaac.”

“Stepbrother,” he corrected me.

I looked at him. “So? I still see you as my brother.”

“Come on. We’re not blood related,” he said. “And you’re getting hard. Harder.”

“That’s because you’re touching my dick,” I defended myself. His hand was warm and it felt good on my crotch.

“Yeah. And you’re not exactly telling me to stop,” he said, sliding his hand under my underwear. I muttered a quiet “fuck” as his strong masculine hand wrapped itself around my hard cock.

“I-I’m not gay,” I said.

“Neither am I,” he shot back. “This is just… to help you sleep. Just like you said.”

“S-sure,” I said. With his other hand, he tried to pull my underwear down, and I instinctively lifted my hips up. “Shit…”.

“What?”

“N-nothing. Just feels good. It’s been a long time since—”

“Yeah yeah, I know, you told me,” he said. “Just let your big brother take care of you.” He closed the lid of his laptop and handed it to me. I placed it on the nightstand without question before he pulled the covers off, exposing my hard cock. “Damn, it’s even bigger than I thought.”

“Y-yeah,” I said, awkwardly. I felt so exposed and vulnerable, but I didn’t care. His hand around my cock felt great, so brother or not, I wasn’t gonna stop him.

What I wasn’t expecting was him leaning over. “Woah-woah,” I said, but before I could finish, he wrapped his soft lips around my cock. “Agh—”

He moaned around my dick as he licked the tip, and then the slit, before going down on me, pushing my cock into his mouth. His mouth went up and down and my hand immediately went to his head to guide him.

“I didn’t… fuck… I really wasn’t trying to start anything sexual earlier—” I said, still feeling conflicted about this. I didn’t want him to think that I came here so that he can pleasure me because of my sleep disorder.

He moaned around my cock. He grabbed it in his hand and pulled back. “Shhh, it’s okay. It doesn’t matter,” he said, wrapping his lips around the shaft, sliding down his wet and hot tongue to my balls to play and suck them as he stroked me. His hand squeezed my thigh, and it made my toes curl from how good of a cocksucker he is.

He went back to blowing me, taking me deeper and deeper with each thrust. I began to move my hips up and down, at first on accident, but then deliberately, fucking his mouth.

He pulled back. “Just close your eyes and imagine I’m a girl,” he said, and I tried to do that, and he tried to keep quiet for me, but knowing that he was my brother doing this to me was too distracting, so I just watched as my cock slid in and out of his mouth.

“Isaac…” I muttered. Fuck, the way he’d suck harder when his lips were just below the tip drove me crazy. “You’re a really good cocksucker… you know exactly what I like.”

He pulled back for just a second, licked the tip and slit again, and said, “I’ve got one too. Of course I know. By the way, you’re leaking.” He said, licking the slit and tip over and over.

“Oh yeah? You like how it tastes?”

“You’ve got no idea.” Him saying that he liked my pre drove me close to the edge. He went back to sucking my cock and his words kept repeating in my mind over and over again. I grew louder and louder, and I hoped that our parents wouldn’t hear us. I doubt they’d approve of their sons giving each other a blowjob.

The risk only made things so much more intense. “Fuck, Isaac, I can’t last much longer.”

Instead of pulling back and jerking me off until I finish, he only increased the speed of sucking me. He was taking most of my thick cock inside his mouth, and before long I grunted, my toes curling, as I finished inside of my brother’s mouth. He made sure to pull back so that I’d shoot my cum on his tongue as he moaned, tasting me, before swallowing everything.

“Fuck yeah, make sure nothing goes to w-waste—” I stuttered as I emptied my balls in him. When he was done, he pulled back. A string of cum and spit was stuck to the tip, which he licked.

“You tasted good, little brother.”

“Fuck… I can’t believe you just swallowed my cum.”

“Don’t think about it,” he said as he lay on his back. He pulled me into his arms, making me lie my head on his chest. I wrapped my arm around him and felt more tired than I ever have before.

I didn’t say anything. I closed my eyes and soaked in the warmth and safety I felt from being held by him, and let sleep take me for as long as it would.
