Buffy's eyes widened when she heard her sister's question. How the hell did she find out? Should she deny it? That wouldn't help, Buffy and Faith were terrible at lying to each other and she would see right through it if she denied it. Faith crossed her arms over her chest after a couple beats of silence.

"I'm taking that as a yes" Faith said, shaking her head. "How did this happen? When did this happen?"

"Faith, you can't tell ANYONE, okay? Swear" Buffy demanded.

"You know me better than that, B. You know I'm not gonna say a damn thing." Buffy sighed with relief and sat on her bed, burring her head in her hands. She had hoped they could go on with their arrangement without anyone ever finding out. "You didn't answer my questions."

Buffy looked at her sister after a moment and sighed.

"It started a few months back" she told her. Faith sat on the bed next to Buffy.

"How did this happen?" Faith asked. Buffy blushed a little.

"Do you really want the details?"

"Not the kinky ones, I just wanna know how you two went from being friends to being fuck buddies" Faith told her and Buffy looked at her, mortified.

"Faith!"

"What? Too direct for you, princess?" Faith joked and Buffy rolled her eyes.

"Do you want the story or not?" Faith nodded, shutting up to let Buffy speak. Buffy sighed, thinking if she should tell Faith about how her and Spike's sexual relationship began. After a moment she decided to continue.

"Okay…"

* Buffy's Memory *

Buffy was sitting in Spike's room, both of them bored out of their minds. Spike was at his computer desk on the internet and Buffy was on Spike's bed, just looking up at the ceiling.

"I feel like I might die from boredom" she told him and he chuckled, turning his chair to face her.

"Wanna play a drinking game?" Spike asked her. Buffy raised her head to look at him with a raise of an eyebrow.

"What kinda drinking game?" she asked, intrigued.

"Never have I ever?" he asked. Buffy smiled a bit and sat up. "Have you ever played?"

"I've played the game, just not with alcohol" Buffy told him. "Okay, sounds fun, let's do it." Spike nodded and went into his closet and retrieved a bottle of Jack Daniels and two shot glasses and joined Buffy on his bed.

"Okay, you start, luv" he told her.

"Okay…" Buffy thought. "Never have I ever…skinny dipped" Spike smirked a bit and poured himself a shot, taking it right down. "Seriously? When?"

"Wouldn't you like to know, Goldilocks" he smirked at her and she rolled her eyes at him. "Okay, my turn. Never have I ever…broken a bone." Buffy took the Jack bottle and poured a shot into her glass and took it down, making a face.

"Ugh, okay, my turn" Buffy said. "Never have I ever…had sex" Spike rolled his eyes and took the jack bottle from her, pouring himself another shot. Buffy smirked a bit, she knew he'd have to drink for that one. "I should make you drink for every girl you've banged, you whore" Buffy joked, pushing him in the arm.

"Yeah, yeah" he told her. "Okay, my turn…"

A half an hour later they were both drunk.

"Never have I ever…" Buffy said, her speech was slurring by now. "Uh….what was I saying?" they both laughed.

"I don't know" Spike said, leaning back on his bed. Buffy leaned back as well.

"Do…do you think it's lame I'm still a virgin?" Buffy asked him. He looked at her, still very drunk, but surprised.

"Course not, luv" he said. "You'll find the right guy one day." There were a couple beats of silence before she turned to him, propping herself up on her elbow.

"What if I want you to be that guy?" she asked, he lifted his head a bit to look at her, in total shock.

"What did you say?" he asked.

"What if I want you to be my first?" she repeated her statement in different words. He sat up and she followed.

"Uh…th—that's not a very good idea, pet" he said, feeling a little uncomfortable. He couldn't believe what she was suggesting.

"I get it, I'm not as attractive as those other girls you were with" Buffy said, feeling a little self-conscious at this time.

"God, no, that's not it at all, Buffy" he assured her. "We're friends, I—I don't want anything we might do to ruin that."

"Well…what if it didn't ruin anything between us? I mean, I think that we're both old enough to be mature about this."

"You're serious aren't you?" he asked, astonished as he got up and faced her. He couldn't believe she was actually suggesting they have sex.

"You want me to be?" she asked in a seductive one as she got up and walked over to him. Their faces were inches apart as she took his hand in his. Before he could answer he felt her lips on his. His first instinct was to pull away, but his hormones got the better of him as he felt her tongue creep into his mouth. He slowly deepened the kiss, gently pulling her against him. He couldn't believe this was happening. He could feel her backing them up to his bed and broke the kiss.

"A—are you sure about his, luv? I don't want you to regret this and resent me" he said. After all, this was her first time and they were both drunk.

"I'm sure, are you?" she asked him. The look in her eyes told him she wanted this, badly. Without saying another word, he crashed his lips on to hers again, their tongues meeting once more. He laid her down on his bed, slowly crawling on top of her, kissing her neck. She closed her eyes in pleasure as she worked his way down her neck to her chest and back up to her mouth.

Buffy lifted her arms as Spike pulled her shirt over her head to reveal the lacey bra she had on underneath. His hands roamed her body, rubbing her stomach and pulling at her jeans. Buffy arched her back so that he could remove her pants. Once she was in her underwear, he removed his shirt as well, removing his black jeans right after.

"I'm gonna ask you one more time, are you su—" he began to double check, but was cut off by her lips crashing on to his yet again. She wanted this more than he knew and he wanted it to. He removed her underwear and bra, leaving her naked next to him. She became a little self-conscious at this point and crawled under the sheet on his bed.

"Hey, no, don't" he said softly, uncovering her. "You don't have to hide from me, I think you're amazing." She gave him a small smile and he took off his boxers, revealing himself to her. She had never seen the male form before. He looked incredible. He was hard by this point and, though she was very much turned on, she didn't really know what to do. He gave her another soft kiss before reaching into his drawer and pulling out a condom.

"I want you" she whispered in his ear as he rolled the condom on to his member.

"God, I want you too" he whispered back, kissing her neck and earlobe. He gently parted her legs, rubbing up them to her inner thighs. She shivered with anticipation as he positioned himself in the right place. "Relax" he told her sweetly.

Buffy took a deep breath as she felt him enter her slowly. She gasped, she didn't expect it to hurt like this.

"Are you okay, luv?" he asked, seeing the look on her face. She nodded without saying anything. "Does it hurt?"

"Just a little, don't stop" she lied. It hurt more than 'just a little', but she didn't want to stop.

"It'll get better, I promise" he whispered to her, moving in and out of her as gently and slowly as he could until she got used to it.

After a couple minutes he could feel Buffy start to relax. She had started to moan now and it got a little louder the more he pushed into her.

"How's that, pet?" he asked. He could feel her fingernails digging into his flesh.

"Harder" he was surprised to hear him say, but obeyed as he pushed into her with a little more force and speed. Her legs tightened around his waist as she continued her moaning. "Oh my god, Spike."

He was turned on by the sound of his name from her and went a little harder, still careful not to be too rough with her.

"Please don't stop, I think…think I'm gonna…" she tried to say, but the pleasure was too great. She let out a scream as he felt her tighten around him. He knew she had arrived when he felt her pulsate and quiver around his member and he wasn't far behind. He collapsed on top of her as he felt himself climax.

They laid there, him on top of her, for a minute until he felt her quit pulsing. He slid out of her, collapsing on the bed next to her, both of them panting heavily. He looked over at him and she smiled weakly at him, as if she didn't know what was supposed to happen now.

"You okay, luv?" he asked.

"Yeah" she said simply and he stretched his arm out.

"Come here." She scooted over, laying her head on his chest and snuggling into him. "Was it okay? Being your first time?"

She smiled bigger at him. He had been so sweet and caring with her. "It was amazing" she told him and he smiled as well, happy that it wasn't a disappointment for her.

"I'm glad, luv" he told her. She looked up at him.

"Was it okay for you? I know I didn't know what I was doing and I really just laid there, but—" he cut her off with a soft kiss to her lips.

"It was incredible; YOU were incredible" he told her. She smiled again, laying her head back on his chest. Before long, both of them were sound asleep.

* End of Buffy's memory *

Faith looked at her twin sister, in total shock. She couldn't believe that Buffy had been the instigator in all of this, she was sure Spike would have been.

"Holy crap" Faith said after Buffy finished her story. "And you two have just been banging ever since?"

"Pretty much."

"Are you in love with him?" Faith asked. Buffy shook her head.

"We're not in love, we're just…friends with benefits I guess" Buffy told her. She could tell Faith was having trouble getting her head around all of this. "How did you know, Fai? I mean, I was sure we were being so careful that no one knew."

Faith looked at her twin, as if she was afraid to speak.

"What?" Buffy asked.

"Okay, don't be pissed at me, I swear this was an accident" Faith told her and Buffy crossed her arms over her chest.

"What did you do?" she asked with a sigh.

"Your laptop was open, and I may have…seen your journal entry" Faith said and Buffy's eyes went wide. "I didn't mean to; it was just there."

"Oh, so you had to read the whole entry?" Buffy asked, a little angry.

"Come on, B, you know I don't do that. I couldn't help it, it just happened" Faith told her. Buffy felt anger at first, then sighed.

"Did you read any others?"

"No, of course not" Faith told her. Buffy shrugged.

"Okay, you're forgiven" she told Faith. Faith was still trying to get her head around the fact that her twin sister had been having a secret sexual relationship with one of their friends.

"I just still can't believe this, B. And no one else knows?"

"No one, so you'd better not say anything to anyone or I'll kill you" Buffy warned her and Faith nodded.

"I swear; you know you can trust me" Faith said. "This is so crazy. How am I gonna look at Spike the same way now?"

"Well you'd better figure it out until I tell him you know" Buffy told her.

"Wait, you were just plannin on keeping this up without ever telling me? I'm your twin sister and your best friend" Faith said, a little hurt.

Buffy sighed. "I'm sorry, Fai, I really am. I hated keeping a secret like this from you, but Spike and I both just agreed it'd be easier and better if no one knew."

"Could you imagine if mom ever found out?" Faith laughed.

"Yeah, I hope It'd be a funny aneurism" Buffy added with a chuckle. She couldn't even think about her mom finding out about her and Spike. As far as Joyce knew, all her daughters were still virgins. Well, at least she still had 1 out of 3. "Now that you know, just keep it cool, okay?"

"You got nothing to worry about, B, I promise" Faith assured her and Buffy sighed, still unsure about even Faith knowing her secret.
