Caitlin was actually hot, feeling her core warm to the point of fire. Barry was touching and kissing her in a way she had only ever dreamed of. And trust me, after having had Savitar so deep inside her so very many times, her body craved Barry so very badly. She wanted to be dominated, used, loved and desired. She wanted to be treated like the goddess she was. From the feel of Barry's sex through their clothes, he was more than ready to make her his.
Quickly her hands went to his pants, fingers undoing his jeans easily. Cool fingers slipped past his boxers to grip his manhood, his skin so hot and silky. Damn she needed him drilling her deep. His body jerked, breaking the moment long enough for him to pull back and ask,
"Are you sure?"
"If you don't make love to me right now Barry Allen, I will freeze you and I guarantee there will be no recovery, even with your speed healing." For emphasis, she slid her hand down and cupped his balls, tickling the underside of his dick. That spurred him into action. In a blink they were naked and Barry was easing her back onto her bed.
Eagerly Caitlin opened her legs, and she was not disappointed. Barry swooped down, licking her eagerly. His hum of approval vibrated her button, and she cried out in pleasure. His hands came up and pressed her legs further apart, burrowing his nose and tongue deep. He licked her like she was an ice cream, making her squirm and massage her own breasts. He kept lapping at her, shooting her higher and higher until she exploded.
Mind in a fog, Caitlin felt Killer Frost drift forward.
"Damn, that was so good. Think you're up to more?"
"More?"
"Savitar would take me a dozen times or more a night. Trust me, if Barry is the same way, you're about to have your body fucked in a way you'll crave for the rest of your life."
As Caitlin and Frost conversed, Barry crawled up her body to hover over her on the bed, self satisfied smirk on his lips. She returned his smirk, reaching up and pulling him down to her, kissing him gently. Their kiss warmed his lips back up. Kissing and touching, they lost themselves in each other again. The fire between them blazed higher and higher, the air between them humming with electricity.
"Ready?" Barry breathed, eyes lit up with lightning, body finely vibrating.
"God yes!" Caitlin bucked her hips, moaning in joy when he pressed into her, stretching her pleasurably. Barry's eyes rolled into the back of his head, hips sinking into hers. This was home, Caitlin thought. Here, now, in Barry's arms and holding his body inside hers. This was what she was made for, to love her speedster.
"More." Caitlin begged softly, body craving more.
"Hang on." Barry whispered before becoming a blur. He was super speeding his body against and inside hers. A scream of pleasure ripped from her throat, white light blooming behind her eyelids. She would have imagined that her body wouldn't be able to take the punishment of being ridden at the speed of light, but it made her crave him more.
Faster and faster they climbed, reaching for that ultimate goal. Caitlin lost track of time and all of Barry she could see were his bright green eyes burning into hers. More time passed; it could have been seconds, it could have been hours, all she knew is that her body craved release. Something deep inside clicked, freezing them both in place, crying out as they reached their peak.
Slowly, so very slowly they came down from their high. Caitlin felt completely limp as Barry crashed to the bed beside her, breathing heavy and covered in sweat. His body temperature was alarmingly high, so Caitlin activated her powers, bringing her body temperature down. Cool mist rose off her body as his heat subsided, settling over Barry, cooling him off.
"Now that was a ride." Frost murmured happily before drifting back, settling down for the night.
"I love you Caitlin Snow." Barry whispered, barely awake.
"I love you too Barry Allen." Caitlin pressed a kiss to his temple, reaching down to pull the blankets up over them. Her heart was happy and her body sated. Now all she wanted to do was sleep next to her love and let the world drift away.
Back across town, a young girl sat on the bed she slept in, reading her journal. Her journal with the special language of the Time Glyphs in it. Nora smiled as she watched her body become translucent. As much as she was sacred to be erased from the timeline, she knew that her consciousness would be assimilated into the Speed Force. She knew that her father had finally found the path he needed to take to prevent reality from being erased. Sacrificing her life to save countless others was a price she was willing to pay.
"I love you mom and dad." Nora whispered into their universe before she faded away completely. It was almost as if she had never been there in the first place.
In the end Barry and Caitlin, along with Cisco, did manage to save the universe, just not the multiverse. All realities were compressed into one universe, one timeline. Earth-38 joined their reality along with Earth-2. Kara, Clark, Harry and Jessie were now in the same universe as Team Flash. There were other villains and bad guys that would come around over time, but every time they would be beaten back by the Flash and the other heros on Earth.
