Brothers (Smut)

Incest warning- smut warning- @isasofia07 requested top Barry bottom Oliver and @roei090 requested smut and @jupitersummers requested them being brothers and I've combined it into one.

"Boys! Let's go" their mom called upstairs. "Barry's not even done packing" Oliver called. "Oh shut up," Barry said rushing to finish. "Oliver help your brother" their father called. Oliver groaned and help Barry finish packing. They managed to get Barry packed and his bags in the car. They all got in the car Barry and Oliver in the back and their parents in front of their father driving. Barry and Oliver stayed quiet. They were normally pretty close so this was odd behavior. "Everything okay boys? You guys are quiet" their mom said. "Mhm," Oliver mumbled. "We're fine," Barry said. Their mom didn't buy it but didn't push it.

The car ride to the airport was short but the flight was long but soon they were on their Hawaiian vacation. "Alright boys this is your room your gonna have to share the bed," their dad said. "But dad it's a twin," Barry said. "So what you to cuddle all the time anyway your brothers it's fine," he said. They both sighed but knew arguing was pointless so they just unpacked.

It was late so once they unpacked and had dinner they went to bed. The boys laid down both as far away as they could be without falling off the bed. Their parents were asleep in the other room. "Hey, Ollie" Barry mumbled. "What" he mumbled. "I miss you" he mumbled back. "What are you talking about?" He asked. "We used to be close and now you jump back when out shoulders brush... it was an accident," he said. "We're brother Barry it's weird either way," he said. "I tripped Oliver and as you caught me our lips brushed it happens it was an accident," he said. Oliver sighed but moved over wrapping an arm around barry. "Does that mean you forgive me?" He asked. Oliver nodded, "I was never mad at you," he said. "So why are you acting like this?" he asked. "You know why," he said. Barry sighed because he did know why. He knew what they both felt in that kiss and he knew it was wrong. "How do we stop this" he mumbled. "Ignore it," Oliver said. "Easy for you to say you know I'm not built like that" he mumbled. "Yeah I know" he mumbled kissing Barry's head. "Get some rest," he said. "I don't want rest" he mumbled. "What do you want?" Oliver asked knowing the answer. "You" he mumbled. "We can't" he mumbled. Barry rolled over facing Oliver, "why?" He asked. "We're brothers," Oliver said. "I don't care and no one has to know," he said. "It's wrong bear" he mumbled. "Then why do we both feel the same way?" He asked. "Just shut up and kiss me" Oliver mumbled. Barry eagerly leaned up kissing him Oliver kissed back. Barry crawled up onto Oliver straddling him and immediately deepening the kiss. Oliver kissed back his hands wrapping around Barry's neck pulling him close. Barry dominated the kiss and Oliver didn't protest they both knew Oliver was a bottom even if he didn't act like it. Barry's hands ran under Oliver's shirt but Oliver broke the kiss. "Wait we can't," Oliver said. "We already talked about this your the one who said to kiss-" Barry's started but was cut off "no I mean we can do this right now mom and dad are just in the other room," he said. Barry sighed but he knew Oliver was right he groaned and rolled off of Oliver. "They'll be gone for date night tomorrow though," he said. Barry smirked happily "can't wait," he said. Oliver chuckled and wrapped his arms around barry who cuddled into him.

The next day went by slow for the boys as they anticipated the events that would take place after their parents left. At around 6 that's exactly what happened and the second the boys were sure they left they were all over each other. Barry had Oliver pressed against the wall his leg between Oliver's as they made out deeply. Eventually, Barry pulled Oliver off the wall and into their room. He pushed him down on the bed taking this opportunity to pull off his shirt before reconnecting their lips. Barry's hands ran under Oliver's shirt and he broke the kiss to pull it off, discarding it on the floor. Barry kissed down Oliver's neck nipping and sucking softly leaving multiple hickeys. "I can't hide those," He panted softly. Barry chuckled softly as his hands went down to the hem of Oliver's sweatpants and he broke the kiss for a moment to pull them off, immediately reconnecting them and pulling his own off as well. Barry palmed Oliver's hard cock gently making the older boy moan softly against Barry's lips. After a moment Barry pulled away and ruffled through the nightstand until he found the lube they'd bought. Oliver watched him as he pulled off Oliver's boxers, sat between his legs and lubed up his fingers. Barry pushed one in and Oliver moaned quietly, gripping the sheets as Barry stretched him open. Slowly one fingered turned to three Barry was gentle but not to slow and fingers found all the right places. Oliver was already panting heavily his head thrown back. Barry pulled his fingers out causing Oliver to whine softly. Barry chuckled "patients," he said. Oliver rolled his eyes but Barry was just as desperate and wasted no time in pulling his own boxers off and lining himself up and slowly pushing in. Oliver groaned his hands going up and gripping Barry's back tightly. Barry moaned quickly as he bottomed out giving Oliver a moment to adjust. After a moment Oliver nodded and Barry slowly started to thrust. His trust started slow and even but as time when on, they became fast and sloppy. Barry was panting heavily as he thrusted deeply into Oliver who was a moaning mess gripping and calming at the youngest back. "Fuck bear I'm c-close" Oliver panting. "Me t-to" Barry painted his thrusts getting faster and harder until Oliver come undone underneath him, cumming hard across their chests with a moan of "bear". This caused barry to release inside Oliver muffling his moan in Oliver's neck as his motions slowed. They both laid their panting heavily. At some point, Barry pulled out and laid next to Oliver as he caught his breath. Once his breathing was relatively normal he got up and went into the bathroom, he came back out a moment later cleaned up with a rag. He cleaned Oliver up and tossed it in the bin so their parents wouldn't see it. "Softie" Oliver mumbled as he watched him tiredly. Barry chuckled and rolled his eyes and tossed a pair of boxers at Oliver. Oliver chuckled and pulled them on while barry pulled his on along with one of Oliver's shirts. Oliver smiled fondly at him as he came over and cuddled up to him. Oliver smiled and wrapped his arms around Barry. The two went to sleep.
