Is it normal to shoot?

I'm lying down in my bed masturbating away merrily while my ex- is watching TV in the other room. I'm pounding away and I come so, so close to climax...

Just as I climax, my ex- bursts through the door to the bedroom. "There are some guys outside on the porch and they tapped on the front window when they saw me!" My eyes shoot open and I stand up with a start. Stream after stream of c*m shoots out of my c*ck, most of it landing on the floor in front of my ex-.

We stare at each other. She has a look of horror from both the home invader and the unexpected semen discharge, I have a look of horror and shame. Finally, I grab a pillow to cover my crotch and run out into the living room after my ex-.

The two guys are there still, standing on the porch, but they look a bit alarmed. My ex- having run off startled them a bit, and when they saw us coming back I think they presumed that we were bringing a gun. Well, in fact, I was bringing a gun, but it wasn't loaded anymore-- still cocked though.

I figured we had the element of surprise and terror to one-up them so I dropped the pillow, my still erect phallus swinging in their direction, and started to unlock the door. I started screaming "GONNA F*CK YOUR SH*T" at the top of my lungs over and over again. Both guys looked at each other and went completely pale. One of them was holding some sort of weapon I think but he screamed like a little girl and ran just as quickly as the other. I didn't even need to finish unlocking the door.
