We should split up. Send Kirsty upstairs

"We should split up. I'll stay here, you go upstairs. Let's see what these letters say."

"You just want to see what's in the box before the rest of us do," Kirsty replied. I wasn't sure if she was teasing or genuinely accusing me.

"I promise I won't look in there until we're all together again," I said, earnestly.

"Well, ok. But I warn you: I'm very horny and our son now has a magnificent cock."

"I know, and he's not afraid to use it!" I replied with a smile.

"Anywhere!" added Kirsty, patting herself on the arse as she left the room with her envelope.

I sat on the sofa again and opened my envelope. Inside was a smartphone and a letter from Dr Baxter. I started to read.

Dear Billy,

Welcome home! I'm so glad you've received this box of goodies. I suspect you've figured out that some operatives from the Club needed to let themselves in so they could deliver it. More on that subject a little later.

Firstly, though, I need to urge you to ensure Lucy and James read their letters from me as soon as possible. No doubt their interest had been aroused - it might not be the only thing that has been aroused! - and it's important that they understand all the benefits and responsibilities of being a member of our club.

At this point my reading was interrupted by a joyful shout from James upstairs. My own letter continued:

Attached to this letter are the details you'll need for accessing the club's online facilities. Needless to say your account details are unique to you and must not be shared with anybody - not me, nor any other club members, including members of your family. As head of the family, there are certain privileges that you have that are not available to Kirsty, Lucy and James.

I hope you don't mind that when our operatives delivered this box, they made one or two enhancements at the same time. These include a new set top box for your television with access to some rather special channels, a new internet router that's also connected directly to the club's private network and hidden cameras all around the house. Don't worry, you are in full control of these - this is one of your head-of-the-family privileges. You can activate the cameras via your new mobile phone, which I have enclosed. Naturally there are numerous other clever functions to your new device, which I'm sure you'll discover at your leisure.

I heard the sound of floorboards creaking upstairs, and muffled voices. I continued reading:

There are also some other gifts around the house - some new clothes, toys and other bits and pieces - which I'm sure you'll all enjoy discovering.

With that, I shall leave you to it. I look forward to catching up with you soon and making my acquaintance with James and Lucy.

My fondest regards,

Dr Baxter, Club President.

PS For obvious reasons please destroy this letter after you've read it and learnt your login details.

There was a rhythmic creaking from upstairs now. I took care to memorise my login details for my new phone and access to the club network, and headed to our study to shred them before deciding how to investigate what was going on upstairs?
