To say anticipation is a great BDSM state of mind is understating it really. Here's another little scenario over the years where I have used that state of mind with my sub.
In the early days of Yahoo, I'd made friends with a sub online and after a couple of months and having talked on the phone we decided to meet up at a hotel near her. I booked a room, and go to the hotel an hour or so before were to meet.
It was a first time meet. We had talked online for a while. We sat and chatted in the bar for a while so she was comfortable, and said she would like to go further. I gave her a key to the room and said there was a note for her on the bed.
She was obviously nervous when I got up to the room. She had done what I had asked, stripped, then put cuffs on wrists and ankles and blindfolded herself with the items I had left on the bed with the note. I had told he to sit at the end of the bed for me. But she was shivering with pure anticipation (it wasn't cold as it was mid-summer). She later told me some of the wonderful things that had bene going through her mind as she prepared herself for me and while she sat there waiting.
We had a very nice afternoon which I won't go into detail about here. Sadly though, she lived in Nottingham and it was far too distant for me to meet regularly. We chatted for quite a while on line but never got together again.
