Firstly this is a work of fiction and I don't endorse or encourage any form of incest IRL. If you get offended by that kind of stuff you shouldn't read any further. Secondly I haven't decided what's going to happen yet and I am open to input about the storyline :) I'm not that great a writer so I apologise in advance.

'I'm sorry I didn't tell you earlier,' Trick said raising his eyebrows and closing the ancient dusty book in front of him.

'Holy Macaroni!' Kenzi exclaimed 'So you're saying Bo has a sister from another mister?'

Trick looked forlorn.

'Yes,' he replied heaving the book back onto the shelf.

Kenzi poured herself another shot of tequila as Bo leaned forward over the bar, looking at Trick with a serious expression.

'Who is it?' She pressed.

Trick looked at Bo and then at Kenzi, he gave a heavy sigh before looking back at Bo straight in the eye.

'Bo,' he said in a low voice 'it's Tamsin.'

Kenzi nearly choked on her tequila and Bo's jaw fell ajar.

'Tell me this is a joke,' Bo said at once.

'I'm afraid not,' Trick returned.

'Does she know?' Bo asked, leaning in further so passers-by wouldn't listen in.

'No,' Trick replied 'I haven't told her yet.'

At that moment Bo felt a hand on her shoulder and she turned around quickly only to be faced with Dyson.

'Woah there!' Dyson said 'are you okay; you look like you've seen a ghost?'

'I'm fine,' Bo said, looking past him and trying to get her thoughts straight.

Dyson looked slightly hurt before he regained his normal composure, Kenzi gave Bo a concerned look.

'I need some air,' Bo said at once before pushing her way past Dyson and out of the bar.

As soon as she was outside she slammed her fist against the brick wall in frustration. Tamsin was her half-sister; an array of emotions swelled up inside of her ranging from fear to confusion; Tamsin had kissed her, more than once and searching her feelings she knew deep down that she had liked it. How could things have become so messed up in such a short amount of time? She had to tell Tamsin the truth and she had to cut off whatever was between them; maybe they could even laugh about it, it wasn't like they'd done anything more than kiss and one time it had been necessary to restore Bo's strength. Bo knew she had wanted to do much more than kiss Tamsin though, she had thought about it every night since they'd first locked lips… At that very moment she felt her phone vibrate in her pocket; she picked it up and answered it.

'Hey Succubus…'

'Tamsin?'

'Who else? Listen you need to come back to yours now, I have something for you,'

'Tamsin, we need to talk.'

'I agree, so make sure you come along; give Kenzi twenty dollars and tell her to buy herself a new beer jacket.'

Tamsin hung up and Bo was left staring at her phone. Suddenly, Bo felt nervous; she really didn't want to go home and tell Tamsin that they were related so it was no longer appropriate for them to suck face. She took a deep breath and made her way back to the house, running away was out of the question. She text Kenzi to tell her to stay at the bar until further notice, not that Kenzi would have made plans to leave the bar anytime soon.

Bo arrived outside her own front door and tried to calm herself down; it would be fine, she'd just say it and it would be out in the open, if Tamsin had a problem with it, it would be her problem. She unlocked the front door and stepped inside.

'Hello?' she called out.

There was no reply. She took a few steps further inside and nearly did a double-take; Tamsin was sprawled out on the sofa in nothing but a black laced bra and underpants. Her blonde hair swung as she waved to Bo from where she sat.

'What's a tall dark succubus like you, doing in a place like this?' Tamsin joked, as her bright eyes locked with Bo's troubled dark ones.

'Tamsin,' Bo said taking a step closer.

'Aren't you going to come and sit down?' Tamsin asked, rubbing the seat next to her.

Bo bit her lip and sat down on the far end of the sofa. Tamsin immediately straddled her causing Bo to look at the ceiling; anywhere apart from the barely contained bosom in front of her.

'Tamsin, listen,' Bo said as Tamsin started to kiss her neck 'I have something serious to tell you… stop…'

Tamsin bit down on Bo's neck causing her succubus instincts to rise inside of her; she struggled with trying to contain the hormones rushing through her body and found herself sliding her fingertips alongside Tamsin's exposed back. Tell her her brain scolded her as she felt her fae needs take a hold of her. Suddenly Bo grabbed Tamsin by the arms and looked into her eyes.

'Tamsin…'
