Attempt at story

The moon was out, illuminating the outside.  I was sleeping naked dreaming sweet dreams when a cold came in.  Way too cold.  I got up and put on a loose robe to check.  The windows in my room were closed but at the door it was cold.  I go to open it and check.  As I look, I see a window open in the kitchen.

"Strange I di..."  Then I noticed

A dark unfamiliar.  It moved with great speed knocking me to the ground.

"What the hell wh..." A punch to the gut knocks out my air.

A dam robbery perhaps might be the end here and now, yet it was going to be so much worse.  After the punch my robe came undone, I am flat on the floor with my flaccid cock out and testicles exposed to the cold.  I can barely see anything, but the intruder in a black outfit, impossible to tell who or what they are.  The intruder moves in-between my legs casting my penis aside like some common meat and moves onto my loose ball sac.  They grab at my right squeezing hard.  The pain is felt deep inside me, but I am too still crippled from before and the pain from this is too much now.  I try to scream but a piece is cloth is put in my mouth.  They let go.

The intruder looks again seeing what they desire, my most valuable piece of me.  They want my balls.  They also want to have fun with them first.  They kick me in the nuts, twice, thrice in quick succession.  Bile builds in my throat, oh god it hurts so dam much.  They feel around after, feeling my cords and they pull tight on them trying to rip them off.  But my cock stirs from this getting erect from the handling of my balls and then, a punch to the balls.  

\*WHAM\*

I pass out a bit as I feel a dull but growing ache in my testicles but then I notice something shine.  Oh god a knife.  They have a bander and put my testicles through, one it tight, two no, please no.  It closes denying them their life-giving blood.  My future children dying in my ball sac.  The intruder moves their attention, they see my cock at full mast and...

\*SNAP\*

They.. This beast.. my cock is stomped on hard and snaps in half I am ruined even if someone helps.

The knife the moves down, past my broken dick, right to my babymakers.  This is it.  I try to get up, I get stomped on they are too strong.  They take my balls, my blue dying balls and the cold knife I feel it.  I feel it as it slices.  My scrotum tears away, I want my balls I want to keep screwing, no shit.  I feel my cords the cold it hurts.  My balls and sac fall to the floor.  It over, I will never pump out sperm again.   
 They take my balls, putting it in a clear jar.  I can see something of their face, they..  Smile as they leave.  I am forced to get up as I try not to think what I just lost.
