"Yes, of course!"

You excitedly lean forward. Christmas and the presents you have yet to receive is all but forgotten as you hang on every word your Grandfather says.

"Ok, when I was in school, I was very interested in mathematics, in electronics, and engineering. These interests lead me into the field of computing and I worked with IBM for a short while, and was really heavily involved in the launch of the personal computer. That's where I made the majority of my money, and while the work was rewarding. It wasn't really what I wanted to be doing. My other hobby was inventing things, although like many people at the time, I struggled to invent something of any real use. More often than not, any idea that I had already appeared as I tried to hurriedly put together a prototype. During this time, I met and married your Grandma. Our life was a passionate one, and she was the one that put me on the path that has eventually led me here."
"You see... I always wanted to do something that brought the world joy, happiness and pleasure. And so my beloved wife asked me, why don't I invent a new... sex toy..."

He looks at you a little sheepishly, as if expecting you to be suddenly outraged and storm off. It's obviously something that he's both passionate about, and embarrassed about.

You smile reassuringly at him. "Grandpa, that's awesome. Please, carry on."

He lets out a sigh of relief and continues his story.

"Where was I? Oh yes, so by this time, there were all sorts of machines and vibrators out there. But there seemed to be a niche for portable, home use sex machines. So I ran a company that sold these machines in a variety of sizes and shapes for both men and women, and they were very popular and I became reasonably wealthy. But it still wasn't quite right, I have to admit I was looking for a bit of fame. I dreamt of revolutionising both technology and sex toy industries with some amazing invention. It wasn't to be though. As you know, my Wife passed away when your Aunty was born, and I struggled to raise her and your Mother and stay involved in the company. Your Mother and her Sister of course won that little battle, so while I stayed as a shareholder, I stepped down as CEO to raise my Daughters properly. Even when they were both grown up, I never stepped back into the business."
"But that's not to say I stopped inventing. I continued to work on my machines as a hobby, whenever I had spare time. Occasionally I would sell a design to my old company, or they would request something special for a client and I would work on it whenever I could. It wasn't until very recently that I made a break-through on a design I've been working on and off my entire life. I've spent a lot of my money, time and effort into this one idea and earlier this year it became ready for testing."

He stands, his old body groaning and complaining about the sudden movements. You smile lightly at his grumblings as you quickly finish your tea and follow him up the stairs. He has one of those chair lifts installed, however it always amused you how modified he'd made it. He buckled his seatbelt and shot up the stairs at five times the speed of the default setting.

You hurry after him, as the chair continues to take him up another flight of stairs up to the attic. A nervous tremble ripples through your body as you head up the staircase that has previously been forbidden to you. The attic has always been off limits but your Grandfather had always said it was because it was dangerous up there, and he didn't put anything up there anyway. Of course you realise now that this was a lie, as you watch your Grandfather unbuckle on the tiny landing and unlock the old wooden door with a key from his pocket.
