Run Back To You

One

Sana was shaking.

She rested on her knees, ass in the air and face buried in dark pillows. She wore nothing but her matching red bra and panties. A thin layer of sweat glistened on her skin and a noticeable wet spot in between her legs. Her ass cheeks glowing red. Her thighs trembled and her breathing unsteady.

A pair of dark brown eyes stared down at her from behind. Tzuyu's attire was a really short tight fitted boxers, deep blue, almost black. Her hand stung, her lips swollen, her own panties drenched. Her eyes sat low as she took in the sight of Sana. She loved Sana like this, shaking and begging, completely at her mercy. The power she felt from it made her tremble and she brought her hand up to slap Sana's ass once more.

The moan that left Sana's lips at the impact had her clenching, she bit her lip to stop the groan from coming out. She rubbed the flaming skin before reaching between her legs to stroke through the soaked lace. Sana gasped and her hips dropped down, trying to rock against her hand.

"Please." Sana's voice was shaky, her fist balled up tight into the sheets by her head. Tzuyu liked working Sana up until she was ready to explode. He liked it when Sana would come for her with just one touch of her fingers on her clit. One time she had made Sana come with just spanking alone.

Sana liked the pain. She got off on it and Tzuyu loved to give it. It was something Tzuyu always wanted to try with Taehyung but he was always too uncomfortable with the idea. It was something she never thought she'd find in Sana of all people. Sana liked to be spanked, she liked to be choked and she liked her hair pulled. She liked it almost rougher than Tzuyu liked to give. She took everything that Tzuyu dished out at her with a positive outcome. Sana was everything Tzuyu was looking for in bed. She met all of Tzuyu's standards and it amazed her how this all came about by accident. It had started almost a year ago.

*FLASHBACK STARTS*

They had been hanging out after one of Tzuyu's fights with Taehyung. They piled up the junk food and watched a bunch of movies in Sana's bedroom and Tzuyu had let her pick because well, she was Sana.

One of the movies had been Along Came Polly. It had all started with the scene where the two main characters were making out on the bed and the man had given her a small spanking.

"I tried to get Taehyung to spank me once." Tzuyu said with a shake of her head as she kept her eyes on the movie and dipped her hand into the popcorn bowl. They both lay on their stomachs, side by side on Sana's small twin size bed. She heard Sana laugh next to her and looked over to find chocolate brown eyes staring back at her.

"Really?"

"Yes really. You see to me Sex and Pain is like Batman and Robin. They're just so good together." She had watched the way that Sana's eyes widened at her words. Her pupils dilated but she paid it no attention at the time. Sana bit her lower lip and her cheeks flushed slightly.

"What did he say?" she asked almost shyly. Tzuyu raised an eyebrow. All of her focus now on Sana instead of the stupid comedy in front of her. She was showing a lot more interest in the subject than Tzuyu had thought she would. It was one of those things that Sana just doesn't like talking about out of embarrassment.

"He looked at me like I was crazy and didn't have sex with me for two weeks. I guess he was afraid I'd ask again. Which I would have. Is it so wrong for me to want him to slap my ass every once in a while when we're doing it?" she asked and watched as Sana slowly shook her head. "Right that's what I thought but he's a fucking prude." She shook her head before a smirk came to her lips. "What about you? Ever let one of your boy toys slap that Japanese ass?" she asked while throwing a glance back at Sana's jean covered ass.
