Now set your timer to 40 minutes.
You cannot leave this position until the timer has run out. 40 minutes is more than enough for an anal orgasm.
You can ride your toy at any speed you like. Try to keep a rhythm. If you think a metronome would help then you may use www.webmetronome.com
I would suggest starting at a slow 20 bpm with a gradual increase towards 140 by the end of the 40 minutes. Don't try a speed you are uncomfortable with.
It is important that pressure is being exerted on your prostate gland, about two to three inches inside your anus.
You can watch any videos you want from this channel http://www.pornhub.com/channels/blacked
If you have never had an anal orgasm before then I suggest you use your mobile phone and film yourself for the rest of this tease.
When the time is up you must press continue.
