Sucker For Pain (OC STORY)

Experiment 62-6 was a useless experiment to see if two animals would survive...connected to each other. Both of them were confirmed to be males to see if the same gender of animals would ruin the experiment. it didn't. In fact, they both fell in love....with each other.
This led them to both want to be free and killed a number of scientist just for their freedom, and it worked.

But what happened before that?
Did they secretly know each other before they were sewn together?
Did they even have names?

All will be said in this shitty story :v
