A/N: I feel incredibly ridiculous calling it 'chi'.

Ok, so there are two versions of this chapter, the tamer one which I've posted here and the more explicit one which I will eventually post as a one shot. Yes this is an M rated fic but technically the other version would be MA if FFN allowed it. The reason for the M rating on this was more because of the subject matter and I know that some people don't want to read smut so I've separated them.

Also I don't particularly appreciate being told that I 'need' to do something differently. I realise that some of you would prefer that Lauren be turned into something other than a succubus (an issue which I intentionally haven't directly addressed) but I can't reconcile the fact that, that would not make any sense whatsoever as it is succubus cells which are in her body as is... Similar, it doesn't make sense for the baby to be anything else, as there isn't another type of Fae in the mix, but I am planning on having the child be different due to popular request...

When Lauren woke with a start it took her mind a few seconds to process why: she was hungry. No, more like ravenous, she thought. But it wasn't food which her body sought, at least, not food in the traditional sense. She was hungry for chi, which didn't make sense. Bo had just 'fed' her, to the point where she had felt like she was going to burst. She shouldn't be this hungry, almost painfully so, this soon.

Once her mind had processed this she began to notice something else. There was a funny feeling in her body, almost like pins and needles, but more wide spread. There was also a dull pounding in her head, starting just behind her eyes and resonating out. It wasn't exactly painful, just strange and uncomfortable.

Unsure what was happening, and needing Bo to once again 'feed' her, she reached out and gently shook Bo's shoulder. "Bo?" Receiving little more than a moan, Lauren tried again slightly harder this time.

"Bo? Wake up," she tried again. "Please Bo."

"Lauren? What's wrong?" Bo muttered blearily, half turning to face Lauren and trying to force her eyes open, but not succeeding. Truth be told, sustaining Lauren and the baby was starting to take its toll on her, as Trick had mentioned, and she was tired.

"I'm… hungry," Lauren told her, voice breaking slightly, still not entirely comfortable with calling it that.

At Lauren's response Bo's eyes flashed open, concerned by the note of desperation in her words. What she saw when she looked at Lauren shocked her still somewhat foggy brain for a second before her thought processes caught up. Trick said this would happen.

Lauren's eyes were blue. A bright, crystal clear blue. The same colour her own eyes turned whenever she embraced her Fae heritage.

"Bo?" Lauren asked, the note of desperation growing. Her need to feed was quickly passing from uncomfortable to painful.

"Ok," Bo reassured her. "Just hold on," she said, rolling over more fully.

Lauren whimpered as Bo finally faced her.

"Feed from me," Bo told her, leaning forward to kiss her.

"I can't," Lauren gasped just before their lips met.

"Try," Bo answered against her mouth. If Lauren's body was changing, and her eyes said it was, it meant she should be able to feed.

As soon as their lips touched Lauren grabbed Bo and pulled her closer. Bo could feel a slight tugging sensation, but it was not nearly strong enough. Letting her try for a few more seconds, Bo held off helping her in the hopes that Lauren's instincts would take over.

10 more seconds passed and still nothing happened before Lauren began whimpering earnestly, now in pain. "Bo," she begged.

"I know," Bo said, breaking the kiss slightly she took over, breathing chi into Lauren as fast as she could.

Almost immediately Lauren's whimpers of pain eased to sighs of relief. Still Bo continued, not holding back, until Lauren's grip relaxed and she pulled back slightly.

"Better?" Bo asked, brushing her hair back as she felt her whole body relax into the bed.

Lauren nodded, "Much, thank you." No longer hungry, she was once again sleepy, her body demanding rest.

"You don't need to thank me. That's our baby you're growing in there," Bo said, her hand going down to caress her stomach softly. "This is the least I can do to help you." Lauren's hand moved instinctively to join Bo's, so that they were both covering their baby.

Seeing Lauren was struggling to keep her eyes open, Bo leaned forward and kissed her softly. "Go back to sleep," Bo told her, placing another kiss on her forehead as Lauren's eyes closed and she gave in to her body's needs.

Once she was sure that Lauren was asleep and not about to wake up again, Bo climbed out of the bed as softly as she could, grabbing her phone as she did.

Making sure to be quiet Bo headed for the stairs, her footsteps padding softly on the wooden floor. She didn't want Lauren to wake up and find her like this. Feeding her a second time had taken everything she had and now Bo was the one who needed to feed. She was grateful they were at her place, neutral territory, or else what she was about to do wouldn't be an option.

Sinking to the floor at the bottom of the stairs she hit the speed dial number.

"Bo? What's wrong?" he picked up on the second ring, despite the early hour.

"Dyson," she managed to say weakly.

"You need to feed?" He asked. The question was rhetorical, he was already pulling clothes on haphazardly, but her mumbled agreement confirmed it regardless. "I'll be there in 10 minutes, ok?"

She muttered something in reply and hung up the phone.

When Dyson arrived at the loft he found Bo passed out at the bottom of the stairs. Rushing to her side, he leaned down, pressing his lips to hers and nudging her lips open.

Barely a second passed before he felt the pull as her body's reflexes took over. She regained consciousness quickly, her eyes fluttering open. He didn't stop her feeding, rather he waited for her to pull back. It took longer than normal, but she stopped.

"You ok?" Bo checked when they pulled apart.

"Yeah, little tired, but otherwise fine," Dyson replied standing up.

Nodding slowly she accepted his proffered arm, allowing him to pull her to her feet.

"Thank you," she told him.

"Anytime," he replied, nodding his head toward the stairs, "go join your girl."

Smiling slightly, Bo turned and headed up.

Dyson watched her until she disappeared from his line of sight before leaving the loft.

A/N: I never understood why she had to have sex to feed from others when she and Lauren were together – in the past we've seen her do it just by kissing them. Even if she did need the sex, she has Lauren for that so it should be enough for her to feed without the sex off other Fae. I think this solution would also be easier for Lauren to accept.
