Shooting Cum and Cumming Twice

There are two ways I like to use to get myself off. The only real difference is one is in the shower, if I'm planning on showering soon, and the other is in the office (if home alone), or the bathroom.

The first thing I do if I'm jacking off anywhere, except the shower, is to get a box of tissues. Then I'll read some stories, my favorites being the female-female and sibling stories (not sure why, they just seem to do the trick) or look at some porn online. If no one is home I also like using some sex books my parents have.

Once I get fairly hard, I pull down my shorts and boxers and start stroking my dick till it reaches it's full seven and a half inches. Then, I start fantasizing about girls I know, or if I'm on the computer still start an online porn clip. As I keep going I play with my balls to add to the pleasure.

When I feel like I'm gonna cum, if I'm not in a time crunch I like to ease up and elongate my jack-off session, which also makes my final orgasm stronger. When I'm finally ready, I go hard and fast, and shoot my load. Lately my load has been landing on my arms and legs when I'm sitting and my stomach when laying in the shower. Sometimes I'll taste my cum, but not that often.

One kind of unusual thing that happens somewhat often is that my dick stays hard, and on a rare occasion it feels like it's getting harder after I come. When it does I normally manage to cum again, and if it doesn't I can sometimes get it up again and then continue to a second orgasm.

Have any of you guys had something like this happen?
