Archie was worried.

If anyone had asked, Archie would've said that of course, Clio wouldn't be expecting anything to happen that night, the night that they finished their project and studied until the wee hours of the morning for their exam and had Joyce and Zeke sleeping in the next room, the night they were exhausted and had no privacy to boot.

No one in their right mind would expect activities of any kind to happen, let alone new sexual ground to broken in a relationship on such a night, right?

Right?

But now that bedtime had come, Archie wasn't sure at all that Clio would know that. She was a mighty determined girl, he'd learned over the past few months; once she set her heart and mind on something, she didn't give up until she got it.

He looked at her, lying on top of the bed, smiling at him. She looked like a sleepy, sexy, mischievous sprite. Archie thanked the mythical gods that they were sleeping in their clothes, and that they were both wearing jeans.

Archie stretched and yawned ostentatiously, making an audible sound of exhaustion. "I'm knackered," he said on the tail end of his yawn. "All that revising for the exam has just done my head in, honestly."

"Yeah, me too," Clio said, rolling on her side to face Archie's side of the bed. 

In that position, Archie could see the deep sweep of her waist to her hip, how it curved sweetly to her thigh and down to her pretty long leg.

He got in bed while ruthlessly yanking his eyes away and turning off the lamp. He leaned forward and pecked her forehead in a chaste goodnight kiss. "See you in the morning, then, Clio," he murmured. "Good night." And he rolled over to face the other way. "Sleep well," he said over his shoulder.

Clio immediately scooted over to spoon Archie, draping her arm over his torso and breathing soft, warm breaths on the back of his neck, making the hairs there stand up.

"Good night, Archie," she whispered. She kissed the skin just below his hairline before cuddling in even closer, tucking her knees behind his. Archie was surrounded by the scent of Clio, the lovely, clean, floral fragrance of her hair and her skin, and he felt as though he were going to float away on it, a virtual bower of flowers lifting him up and sailing him away to dreamland.

How, how in the world was he supposed to sleep with her glorious softness pressed up against him like this? 

Archie resolutely thought about his nieces, their darling, pudgy hands and feet, and tried to fall asleep, and he was so exhausted that he might actually have succeeded. Just when he was on the edge of slumber, however, Clio lifted his shirt and slid her hand under it, letting her palm come to rest on the sensitive flesh of his belly, demolishing his defenses in one go.

Shit.

Sleep fled, leaving in its place an acute awareness of Clio's hand and where it rested on his body, the pressure points of the pads of her beautiful, long, graceful fingers and where they skimmed his skin. It took all of Archie's self control not to grab her hand and press it into his body, or push it lower, over the top of his jeans and what was under them. 

He could now feel her breasts and how they pressed into his back with every breath she took. He even imagined that he could feel her nipples, like hot bullets, and he had to resist the urge to push back into her with every breath he took, Jesus.

Next, Clio moved her legs, just a little, but enough so Archie could feel, and the image of what was happening, of just knowing that her smooth, denim clad thighs were sliding along his in rhythm with her warm breaths, made Archie draw in sharp, deep breaths and grasp the wooden bars of his headboard in an attempt not to turn around and reach for her. She had to know, she must surely feel his excitement.

"Clio, for Christ's sweet sake," Archie murmured, his eyes closed, chin down in his chest, "we can't, they're right in the next room."

"We aren't doing anything," Clio whispered back, moving her hand to the V of his jeans, making him draw in a hissing breath. "I just want to touch you, Archie. I've never touched a boy before, and I'm curious, that's all. You want me to stop, really?"

Fuck it.

Archie put his hand on top of hers and squeezed, so she could feel his erection through his jeans.

"Oh my god," she moaned, pressing on it as she lifted her knees to apply pressure from below. After a few seconds, she unbuttoned and unzipped his pants, pushing the fabric impatiently out of the way as she tried to get Archie to turn around in the bed.

"Hold on, hold on, darling--" Archie leaned over and messed around with his phone, which was in the charger on the side table, for a few seconds. Soft music filled the room.

"Maybe we can keep from wrecking poor Zeke's life tonight," he whispered to Clio with a little smile as he settled back on the bed, facing her this time.

In response, Clio leaned over and kissed him. "Thank you," she whispered. 

Then, to his surprise, she sat up, grasped her sweater at the hem, and pulled it over her head, shaking her hair out after, looking so beautiful in the near darkness it took his breath away. He thought they were going to continue with Clio in her bra, but she reached behind and unhooked it, sliding it off so her breasts were right at his eye level, pert and perfect.

She lay back down and grasped him, making him tip his head back and close his eyes. She put his hand on top of hers and said, "Show me what to do, okay? I want to do it just how you like it."

Archie opened his eyes and looked at Clio. "But what about you? What about what you like?"

"We'll do me some other time, because I have a feeling I'm going to be noisy, and I don't want to worry about having to be quiet," Clio said with a grin.

Archie stared at her, his eyes wide. "Okay," he finally said.

She leaned in and kissed him, pressing their chests together as she gave him a little squeeze, causing him to gasp at the pressure. "Christ, that feels good," he whispered against her mouth. "Mm, yeah, just like that, along the whole length at first, nice and steady, okay? Yeah."

After a few minutes of this, and a lot of kissing, Archie asked her to speed up. "Today won't take long, I'm really excited."

"What about lubrication?"

"Don't need any today, I'm really turned on, like I said."

"Okay."

"Now just the tip, yeah?"

Archie tipped Clio's body back so he could kiss her breasts, but Clio caught her breath, nearly crying out, and shook her head, so Archie stopped, moving back to her mouth so he could kiss her some more.

Then, not even five minutes after they'd started, "Going to come, Clio, sorry."

"Okay, okay, here's your shirt." 

"Oh god, oh god, going to come so hard, fuck--"

Archie gasped, curling his body up and leaning into Clio as he spasmed, over and over. When he was finally finished, he kissed her, over and over, smiling in between.

She was smiling, too, happy that it seemed to have gone so well.

"What are you so happy about?" Archie asked as he cleaned up and got clean shirts for both of them to sleep in.

"I was afraid I'd fuck it up or, you know, it wouldn't go right and I'd have to tell Francie that I did it wrong," Clio admitted. "So now I can tell her that I got it right my first time around."

"You guys really tell each other all this stuff?" Archie asked as they settled back in the bed. He took her in his arms as they cuddled in the bed.

"Of course," she responded. "We're sisters, we tell each other everything."

Archie nodded. 

"Plus, I'll tell my mom," Clio added.

Archie nearly choked in the darkness.

"What?"

"My mom. I have to tell my mom."

"But, won't she tell your, erm, dad?"

"Well, yeah."

Archie was nonplussed.

"Don't you see a problem with that?"

"No, not really. I mean, he's not in love with the idea of me doing these things, but he knows it's bound to happen, and he's glad I waited this long, and that I waited until I met someone I had feelings for. He knows it's part of growing up, it's part of life. It's normale, you know?"

"Normale?" Archie did a pretty fair imitation of an Italian accent.

"Si." Clio was laughing as she answered him.

"So he's not going to come after me with a bull whip or anything for corrupting his daughter?"

"No!" Clio nearly choked on the word as her laughter got louder.

"And you're willing to risk my wellbeing on that?"

"Si."

"Okay, I guess I'll have to just trust you."

"I guess you will," Clio said, her laughter dying down. "Now, let's try to get a little sleep, hm?"

"Okay." Archie kissed the tip of Clio's nose. "I love you, Clio. Good night."

"You do?"

Archie considered. "Yeah, I do."

"Well, I love you, too, Archie."

"Good."

"Good night."
