Darien woke up confused. Usagi was wearing pajamas and standing by his side of the bed. He knew she didn't bother with them unless someone was over. He looked at his clock and it was the middle of the night. Groggily he asked, "Wha-? Serena, what's going on? Is everything okay?"

He watched her fidget and he was even more confused. She hadn't been nervous in their bedroom for a long time now. She said, "I-I know you expect rme to be sleeping in your sister's room, but…." Suddenly he was wide awake and turned on.

He had just finished a big test that day, and he'd been studying a lot for it lately. She had been incredible and so supportive of the time his studies took. He figured now she decided it was time for some fun.

He nodded to her and said, "you know I'm always willing to listen to you when you need something. Is there something you need?"

He watched her feign nerves and said, "I don't know if you'd be willing to help me with… this."

"Why don't you tell me, and we'll see?"

"W-weeeell. Ummm…."

He smirked, she looked so dang innocent it just increased his desire for her. He sat up, letting the sheet fall to his waist. He had been sleeping like he usually did –naked. Darien took her hand and pulled her a step closer to the bed. "Since you're so nervous, can I take a stab at what I hope you need?" He watched her nod.

He kissed the back of her hand and then said, "you notice I watch you when you're here hanging out with my sister."

"You do?!"

He smirked, "so closely."

She smiled and said, "I watch you too. I was wondering if…." She looked into his eyes and said, "can I sleep in here –with you?"

He smirked wide and said, "we'll get to sleeping –eventually. I have other things I'd like to do with you first." He watched her chest heave with panting breaths. She was excited.

"Climb in bed," he instructed as he scooted over to make room for her.

His hand instantly went to her side under her shirt. He locked eyes with her, "you're sure?"

"Completely."

"Finally," he whispered.

She looked at him questioningly, "finally?"

As he moved his hand on her side to her breast, he said, "finally. I've wanted this for a while now." He then pinched her nipple. "I want you, Serena."

She moaned as he roughly grabbed her breast. She whispered, "if I had known that, I would have shown up in your room sooner."

"Now that I have your consent. I'm going to keep going until I hear a 'no' from you."

She scoffed, "you're not wild enough to come up with anything that would get me to say no."

He surged up and pulled her underneath him and then pulled off her sleep shirt. "I'm going to fuck my sister's best friend, and I'm not wild?"

He watched her eyes darken; he knew she loved him to have a dirty mouth during sex. It was the only time he ever swore. He then moved and pulled off her sleep shorts and flicked her clit. "I'm going to have so much fun tonight. And you, my little temptress, you are wet for me." Then thrust two fingers into her pussy. He groaned and said, "and you're so damn tight! Fuck I'm glad you snuck into my room."

He then curled his fingers in her and got a long low moan out of her. His other hand went to her breast and played with her.

He then shifted quickly and thrust into her and roared out in pleasure at the feel of her surrounding his hard cock. As he slowly penetrated her over and over, he locked eyes with her. "You feel so good. I needed this."

She spread her legs even wider and wrapped them around him. "And you're so big!"

He cupped her cheek in his hand as he kept up his slow pace. He then kissed her nose. "Sleepovers change from now on. I want you in my bed at the end of the night. I want to fuck you and wear you out every time. I want to feel your tight pussy and your sexy body. I need this."

He was over being tender by that point. He raised himself up on his hands and did the fucking he threatened. He fucked her hard into the bed. She bounced on his cock and her boobs jiggled. He was rough with taking her in a way that took him a long time to allow himself to do. What won him over to being rough with her was how much she enjoyed it.

She braced her hands against the headboard to keep him from taking her so hard that she scooted up in the bed. "Yes!... So good!... Right there! YES!" She was wild for him, arching her back in pleasure, meeting him thrust for thrust. She was screaming out in satisfaction, and he heard her voice getting raw.

They both orgasmed, and stars burst the edges of his vision. Then he noticed her silver crystal emerging from her chest as she milked him dry. He collapsed next to her and asked. "Did I just fuck the silver crystal out of you?"

She giggled and batted his arm. "Yes." She cupped the crystal in her hand and replaced it back inside of her. "It was a really good orgasm."

He chucked and caressed her cheek. "You're amazing. Thank you for all your support while I was studying. I know it wasn't fun for you."

She rolled her eyes. "Do you know how cool it will be to be a doctor's wife? This is for me too," she teased. Then she added, "this is your dream. How can I not support it? It's become my dream for you too."

He pulled her close and held her in his arms. "I have many dreams. You're by far my favorite."
