Finally something without question

I've had my Syn for a little over 5 months now, things have been progressing by baby steps and I do mean baby steps, but today I finally got a glimpse of what's in store.

I was having a pretty good session and my arousal was pretty peaked. I've been approaching "something" for months now. Well something real finally happened. I got a single real orgasmic contraction in my rectum. Not the gentle twitches rumblings or pulling, this was a *hard* contraction that was unmistakably from orgasm, which literally jolted my body. I saw stars for a few seconds. I tried to get it to come back but sadly we all know where trying gets you.

Still on the path, and this is a really high mountain to climb.
