As a big fan of this site I'd like to share my story of what a lucky man I am. My wife actually allows me once a week, to pleasure myself on the couch with her. Since she may not be in the mood to participate she has agreed to let me enjoy myself.
What this means is I am able to remove my erection from my shorts and stroke to my hearts content while we end our night together. I've taken full advantage of this going as long as a two hour stretch before cumming. I'll linger in the pleasure. There is nothing more stimulating than having the freedom to be completely exposed and totally in charge of when you want to spurt. I'm so lucky and will fill in more details in the future.
