So to continue about where I left off in part 1, I went home that night and left my friend hanging. It turned out to be good practice for what we did next.
In the intervening time we texted and flirted. The possibility of sex came up, I was honest with him and told him I wasn't ready to have sex with him and I don't want to have sex with someone without being in a relationship with them. He said he was alright with that and didn't want to do anything I wasn't comfortable with. It was about then that he brought up playing around with a little bit of bondage. We had first discussed it a couple months back and had joked about it in the intervening time. I didn't expect it to ever be seriously discussed though. I told him I was down for it but I wanted to do some research on it first. When I do something, I do it right. We set a date for when to give it a go. About three days before I asked him if he had any rope. He did not. So I sent him to the hardware store for at least 40 feet of nylon rope which he was to divide into 4 sections, about 10 feet long each. He quite obediently did. The next few days passed very slowly. I spent it reading up on things to do once I had him tied and practicing tying different knots.
