Nice work on the raccoon residue identification, Chai. That is one angle that never occurred to me. I was skeptical at first about your findings and asked some of the other members about your credibility in the semen identification field and they all assured me you were unrivaled.
So, I went over to Bella's and watched the house. I saw Bella let the dog out and then I could see her at the kitchen sink, whistling a tune, apparently oblivious to the scene which was unfolding before my eyes.
Not more than three seconds after she closed the door, the raccoon had materialized from a woodpile in the corner and went about its business...
The raccoon must have heard Bella letting the water out of the sink, because all of a sudden he increased his thrusting with a speed never before witnessed in the animal kingdom. He tossed his masked head back as he climaxed and let out a raccoon roar of approval.
Bella's dog just sat there, impassive, and stared at the fence.
Seconds before Bella opened the door the raccoon had scampered back to his hiding spot in the wood pile, presumably to wait for another opportunity at the penetration of the impassive dog.
I haven't told Bella yet of my findings because the shock may be to great for her system.
