Prompt: "If you can't sleep…we could have sex?"

Rating: Mature

Pairing: Denki Kaminari x Kyoka Jiro

Frustrated…that was how Kyoka was feeling. She had been trying to finish writing a new song for three weeks now and she was getting nowhere. All the tricks she had for getting past her writer's block were not working. So now she was lying in bed next to her boyfriend, wide awake because of a stupid song she wasn't able to finish! With a sigh, she sat up and got out of bed. Grabbing a blanket to wrap around her shoulders, she walked over to her desk and sat down. She clicked on the overhead lamp and picked up her favorite pencil, then just stared at the paper.

"Hey… what's wrong?" Denki yawned. He had woken up when he realized his girlfriend was no longer lying next to him.

"Nothing, I just can't sleep. I've got the idea for this song in my head but I just can't seem to get it onto paper," Kyoka huffed. Denki got out of bed and came over to where she sat. He looped his arms around her shoulders, holding her as he looked at the paper in front of her.

"I've never seen you this stuck before," he said, nuzzling her neck.

"I've never had writer's block this bad before," she replied. "I can't even sleep because it is bugging me so much!"

"Well…If you can't sleep…we could have sex?" Denki grinned, kissing the side of her neck.

Kyoka flushed at his blatant proposal. They had been dating for a while and he had recently moved in with her. It wasn't like they hadn't done it before but she found it embarrassing for him to just come out and ask her like that. "Jeez, you could have been a little more subtle about that!" Kyoka scolded, her cheeks burning bright red.

"Sorry, Babe… How would you like me to say it?" he whispered into her ear.

Kyoka shivered. Her boyfriend may have been considered one of the biggest goobers in their group of friends, but when they were alone like this he always seemed to know what to do to turn her on. He continued nuzzling her and placed a kiss behind her ear, making her hunch her shoulders at the ticklish sensation. Letting go of her, he spun her chair around; putting his hands on the arm rests as he leaned in with that adorable smile on his face.

Kyoka's heart rate sped up at the look in his eyes and she leaned forward, meeting his lips with her own. Suddenly, Denki scooped her up in his arms, spinning around and dumping her onto the bed before crawling over top of her. He unwrapped the blanket from around her as he leaned in, kissing her softly. She reached up, running her fingers through his hair and pulling him into a deeper kiss. He reached down to lift the hem of her shirt up. His fingers tickled her as he ran his hand up her side, his thumb ghosting over her nipple as he reached her breast. Kyoka broke their kiss, gasping at the light touch but Denki just moved to her neck, trailing kiss down her throat to her collarbone. Then he sat up, straddling her legs as he pulled his shirt off before tossing it onto the floor. He pulled Kyoka into a sitting position and took off her shirt, throwing it to the floor with his own.

He cupped her face and kissed her again as she ran her hands up his abs and over his chest. Denki's hero costume did little to show off his muscles which actually made Kyoka happy. It meant that she got to keep this sight to herself. Her heart raced in her chest and her blood ran hot as their make-out session got steamier. Their hands roamed over each other's bodies like they were trying too imprint every curve and every muscle into their minds. Kyoka moaned as Denki took one of her pert breasts into his mouth while switching between sucking and licking the sensitive peak. He let it go with a pop and started kissing his way down to her waist. The sound of their hearts beating, their labored breathing, and his kisses on her skin sounded like music to Kyoka's ears.

"Oh! Wait!" Kyoka sat up suddenly, pushing Denki back as she scrambled off the bed and over to her desk.

Denki groaned, falling face first into the bed were his girlfriend had just been writhing with pleasure under his hands. He looked up at where his girlfriend was writing feverishly. He loved how passionate she was about her music. It was one thing he had admired about her since high school.

"I love you," he said, crossing his arms under his head and smiling at her.

"I love you too," Kyoka smiled looking up at him. She sat down her pencil and crawled back onto the bed, flipping him over and straddling his hips. He put his hands behind his head and smiled up at her. "I guess I just needed some motivation," Kyoka said as she lay down on top of him.

"I'll be your muse any day, Baby," Denki winked.

Kyoka laughed before moving in to kiss him. Denki wrapped his arms around her and rolled them both over, eager to finish what they had started.
