It was a couple of months ago, just before the school summer holidays started.

Mum was doing something in the kitchen. She had her working head on, so we were trying to keep out of her way. The washing machine was spinning at full speed, so Mum was shouting. You could hear her all down the street, although she couldn't hear herself.

"They can help look after the babies" she bawled. "It will be a little holiday for you, both of you, even though you won't be going away anywhere. And it will only be for three weeks, when the school summer holidays start. "

I went into the kitchen and yelled at her. "But they're a couple of spoilt, snotty-nosed brats, you know they are. "

"They're thirteen now. You last saw them when they were about eight. They'll be grown-up little ladies now, you'll see! Anyway, there's no point in arguing. They've got to come, their mother and father have had a bust-up. They're coming and that's final. "

"That's ALL we need", groaned Tanya when I told her the big news. "Cindy and Mindy, the Horror Twins from Hell. "

"Cindy and Melanie", I corrected her, mechanically. "Mum says they're thirteen now, so they'll be all grown up. "

"Kids like that never grow up", she said grimly, with all the assurance of a great big grown-up fourteen-year-old. She laid Suzanne down for her afternoon rest and straightened up with an effort, her mammoth boobs bouncing for several seconds. I watched as the huge mounds of flesh rippled and rebounded against each other under her thin cotton shirt. "And another thing, has anyone thought to tell them we already have three little kids in the house? And who the mothers are?"

"I imagine so", I said, imagining no such thing. "But they'll find out soon enough when they arrive. They'll be here in the morning. "

"Oh, shit! Tomorrow?" Tanya's shoulders slumped. When you have an 80-inch bust and you let your shoulders slump, they stay slumped. Mine is only 61 inches but I know how she feels.


The twins' father delivered them at 10. 30 the next morning. He was away up the lane in a shower of dust and gravel before anyone could change their mind. Off to see his lover, or to patch things up with his wife? Whatever. Mum welcomed the twins, who walked up the path with permanent expressions of distaste on their faces and large bags in their hands.

As soon as I saw them, I remembered all that there was to remember about these two horrid little girls. Then I realised there was something I didn't remember about them. They had grown up a little. At five feet three tall, they were nearly as tall as me. And as well as growing up, they had grown out. Not a little, a lot! A whole lot!

They had matching hair-styles. Their medium-brown hair was tied in matching pony tails with matching pink ribbons. They wore wearing matching jeans, running shoes and T-shirts. And although I couldn't see through their matching T-shirts, I guessed they also wore matching DD-cup bras! These two were seriously stacked. If it hadn't been for having Tanya about the place, I would have thought the twins were two of the biggest-busted thirteen-year-olds I had ever seen.

They came into the house, looking sniffily around as if to say, 'that's something else I hate about this place, we will have to get *that* changed'. Mum saw me watching from the bottom of the stairs and told them, "There's your big cousin, she'll show you the way to your room", and disappeared gratefully into the kitchen.

So I took them upstairs, and opened the door of what would be their bedroom for the next three weeks, and they went in. There was a shriek, or rather twin shrieks. These two really did do everything the same! They probably had their periods in sync. Losing their virginity was going to be a bit of a challenge, but they would probably manage it.

Then I realised the cause of the shrieks. They had just met their cousin Tanya.

Tanya was lying on the bed, feeding Suzanne.

A word of explanation. Tanya was so big, she couldn't easily sit with Suzanne in her lap and feed her, because her nipples were so far in front of her, if the child was able to reach the nipple, Tanya couldn't reach the child. It was what our Daddy referred to as a major design problem. It's not all that major, I sometimes think, when Tanya likes to, such as in the supermarket or at the football match, she can manage perfectly well. But at home, when she wants to be comfortable, she has worked out another method for herself.
