Private Annelid looked in the eyes of his sergeant in disbelief.
"You... want to mate with me?" it exclaimed.
His superior changed his stern gaze to a more compassionate one "Yes. We may have not long left in this world and I want to leave something unique and beautiful before you go". As the private was trying to object, it added "Plus, I've noticed how you've been looking at me since the first day of boot camp".
Annelid blushed, a silent admittance of its longtime longing for the strong wormy body of the sarge then it removed its little helmet and laid on the floor. A thought passed his simple worm mind... could love bloom on the battlefield?
The sergeant approached it and started rubbing their bodies together, squirming and moaning, overlapping their front eggs and exchanging sperm and eggs.
Being hermaphrodites they were at that point both pregnant, they exchanged a long passionate kiss and waited for the mortar shots to finally reach their trench, ending their little lives.
Little they did know that in the morning, just as the miracle of life was developing inside of them, another miracle occurred.
The HQ had ordered a cease fire.
Anatomically impossible tears of joy were flowing down the private's cheeks, but his lover wiped them away with its lower body, using it as a limb. "Don't cry, my dear... we did it" he said.
"They're tears of joy, my love" the rookie replied.
A month after they were as far away from the battlefield as possible, in a nice, pleasant garden with many worm neighbors, growing old together and watching their little wormlings grow up.
