"Mom?... Mamma?... Mo-eeeeeuuuuwwwww!" Emma walked into the living room looking for one of her mothers', only to find them half naked on the sofa in the middle of the afternoon. "What is wrong with you two? You're old and that's just... gross!" Emma shivered and screwed her face up in disgust being very much the typical teenager.

Addison and Teddy quickly jumped off one another, putting their shirts back on as their cheeks burned with embarrassment.

"We're not old" Addison cleared her throat, buttoning up her casual checkered shirt.

"You're over thirty. Sex over thirty is gross... Ugh!" Emma shivered in disgust again, feeling sick and wanting nothing more than to just run away and gauge her eyes out with a spoon, but she really needed to talk to her mothers.

"It's not 'gross', it's perfectly natural" Addison raised her eyebrow. "And besides, you should be thankful that even now, all these years later, you still have parents who want to have sex-"

"-what do you want, Em?" Teddy cut in with an embarrassed smile.

"I really need to talk to you guys about something important... Which is why I'm not spooning my eyes out and bathing my brain in acid to try and rid that image out of my head!"

"What is it, Em?" Addison asked, worried about what her daughter could be wanting to speak to them about.

"It's just... It's... I mean..." Emma started to look nervous now, picking the imaginary lint on her lap, her eyes no longer looking at her mothers face's, instead just staring down at her lap.

"Emma, are you okay?" Teddy asked seriously, taking her daughters hand in her own and rubbing reassuring circles on her backhand.

"It's just, awkward... Luke and I we're just... I mean... Well we we're talking the other day and stuff, and we know that you guys are our parents and stuff... And we don't want to hurt your feelings or anything, okay? That's the last thing we want to do... But, I don't know, I guess we're just curious?"

"Curious about what, Em?" Addison asked, although both of them had a pretty good idea where this conversation was going.

"She just wants... Well, we just want to, I don't know, know who our Dad is?" Luke said as he walked into the living room having stood outside eavesdropping on the conversation, not being able to listen to his sister butcher the topic -especially after being more or less bullied into being the one to bring it up-.

Addison and Teddy, although almost knowing it was coming and had been expecting it ever since finding out they were pregnant, still felt like they had the wind knocked out of them.

"We don't want to do anything with it, we're just curious" Emma tried to reassure her mothers, her heart almost breaking at the sight of them.

"We're not saying you've done a crap job at raising us or anything... Because you haven't. You're the most amazing mom's in the world, I just... It sounds weird but... I want to know if the reason I can't role my tongue or the fact that I snore or the fact that I'm athletic is from the sperm donor or not... I don't want a relationship with him or anything, and I know that this doesn't make any sense to you... I just need to know. I don't know if I'd even do anything with knowing who he is, I just... I don't know" Luke rambled with a sigh, putting his head in his hands and rubbing his temples. "... And if you guys are mad, be mad at me, not Em. She doesn't really want to know, I just bullied her into asking"

"Lukey, we're not mad!" Addison stroked her son's cheek, smiling at him.

"You're not?" Luke asked.

"No!" Teddy smiled at him. "We've been expecting this question for 16 years, obviously its hard to hear but we're not mad. We know it must have been hard for you, growing up and having Mark as the only real male influence in your life, so obviously you're gonna be curious... We're not saying this just because we don't want you to know... But we honestly don't know who he is"

"We didn't get a name for the guy, we just got a number and his characteristics, likes and dislikes and genetics and stuff on a form. We didn't even get a picture of what he looked like" Addison added. "It was a private sperm bank, but if you guys really want to know, I'm sure there's a way. I mean, you can hire PI's for that kind of stuff can't you?"

"Jeez mom, I'm not that desperate to know!" Luke smiled. "I was just curious and I couldn't just let that chance pass me by. You've taught us that. I'm perfectly happy with the family I've got. We've got two mother's who love us... And apparently still love each other -a lot- and that's a whole lot more than most kids have"

"And anyway" Emma started. "At least this way we can still imagine you chose like an astronaut's stuff or something and we can't be let down by finding out that he's actually a douche"

"Hey! Look at you guys!" Teddy smirked. "We clearly picked awesome sperm!"

"In my mind our love overcame all odds and we both magically conceived you guys" Addison shrugged.

"I like that idea too!" Luke flashed a dimply smile. "I love you guys" Luke wrapped his arms around his sister and mothers.

"We love you too" Teddy smiled.

"I just have one more thing to say" Emma twisted her face as the family embrace ended.

"Go on" Addison smiled encouragingly.

"Please, for the love of God, my sight and my sanity, please stop doing it on the sofa that I'm going to bleach the crap out later in the middle of the afternoon!"

"We can't promise anything!" Addison smiled cheekily, revelling in watching both her daughter and her son squirm at the thought of their parents doing it.
