Hormones

'Cat babe, can you grab me some ice-cream, peanut butter and a pickle please while you're up?' Sara is sitting on the sofa watching TV while Catherine is fiddling around in the kitchen. Lindsey and Luke are round Catherine's sisters' house, coming home in a few minutes. Catherine comes into the lounge with said items in her hand.

'I can't believe you are even thinking of eating this!' Catherine said with a shudder handing the food to her lover.

'Hey! I'm pregnant I have an excuse. I don't say anything when you eat gherkins, do I?'

'Yeah but still…' Catherine shudders again as she takes her place next to Sara on the sofa, her hand protectively resting straight on Sara's stomach.

Sara is pregnant with their second child: Catherine's third. They decided to do the same as they did with Luke, using an anonymous donor as they didn't want anyone to play Dad in their kid's life, just a lot of uncle's.

'When are the kids going to be home?' Sara asks before stuffing peanut butter with ice-cream in her mouth.

Catherine takes a look at her watch, 'In about twenty minutes.' Catherine looks at Sara who has her eyebrows raised. Sara leans forward next to Cath's ear.

'Well why don't we make the most of this alone time?' Sara says in the huskiest voice she can muster up. Catherine pulls back.

'You know normally I would babe but I don't really want to kiss you after you have eaten that. You'll have to clean your teeth before you can kiss me again.' Sara lets out a groan as she takes a bite of her pickle.

About half an hour later, Luke and Lindsey burst through the front door. Sara is in the toilet while Catherine is still on the sofa. She looks up to see them running towards her and she engulfs them both in a big hug. Even though she's 13, Lindsey still likes her hugs.

'Hey kids, how was school?' Catherine asks while placing a kiss on each of their foreheads.

'Alright,' Lindsey replies, in her typical attitude. Luke looks at his Mom with his big blue eyes.

'Mommy, Steven was talking about babies to day in school and I know Mom is having a baby but how does the baby get in there?' Catherine looks at Lindsey then back at Luke who has taken a seat on her lap.

'Luke baby, why don't we wait till Mom gets back and she'll explain it to you?' Luke gives a nod; Lindsey tries to stifle back a giggle when Sara walks in to the lounge taking her place next to Catherine. Almost immediately, Luke is looking at her intensively.

'Mom, where do babies come from?' Sara takes a look at Catherine who has her hands up in mock surrender.

'Why do you ask that Luke?'

'Well Steven was talking about babies at school because his Mom and Dad are having one, I was just wondering,' Luke explains giving a shrug of the shoulders.

'Well there is a little egg inside me, and when your Mommy kisses me, fluid goes into my stomach and attaches to the egg making a baby. It's what happens when two people love each other like your Mommy and I.' Sara looks at Catherine who has a big grin on her face and watches Lindsey running out the room laughing. Luke looks at her with a serious face.

'Well I don't want a baby, so I won't be doing any kissing.' Catherine lets out a little giggle. Sara just smiles at him.

'That's good to hear baby. You might feel differently in a few years time.'

'I doubt it. I'm going to my room.' As he leaves he places a kiss on Sara's stomach before going up the stairs. Once he's gone Sara bursts into tears.

'Baby, what's wrong?' Catherine moves over and pulls her lover into her.

'It's just that they're growing up, Luke won't be this cute for much longer. In 3 months he'll be 7!' Sara manages to say through sobs.

'I know, but we have another on the way.' Catherine says rubbing Sara's stomach.

'I know, I know. I'm just being emotional. Blame the hormones!'
