He isn't finished with Larvae research.

Dr. Anderson opened a large clear glass jar and lifted the contents carefully sitting it on the stone floor below the helpless Kim. Kim's lungs filled with the gas and she found herself hazy and gyrating her hips rhythmically. She couldn't tell what the doctor was up to between her spread chained legs but she didn't care. The gas just begged her to find something to fill her empty pussy with.

The doctor watched as the 2' tall egg shaped creature began opening up its top. He had seen this process before and studied its every action. Folds lifted back and spread revealing a soft and slimy interior. Soon one large appendage flopped out and began squirming on the floor. The tube was tipped with a wide, almost mouth like end that seemed to open and close feeling it's way around.

It didn't take the tentacle long to find the bound ankle of Kim. This creature had experience with these types of mammals and it expertly worked its way sucking and licking up Kim's left leg. It stopped as it felt and smelled the female in heat above it. It opened up its mouth slightly before moving in and covering Kim's pussy mound between her spread legs.

Kim felt the wide lips lock on her between her spread legs. The sensation made her arc her back off the wall almost offering her pussy for the taking. She came as she could feel something wet and wide from inside the mouth begin to probe at her pussy lips. A smaller tendril found and began licking at sucking at her clit as the thick member began pushing inside. She moaned as she pushed her hips downward to greet the invading cock like member. The creature began slowly working its way back and forth inside her as it teased her ripe and supple body.

The doctor documented every angle of the mating process. He'd seen it before but still needed more data to draw his conclusions. Video and photographs captured every moan and pleasure filled groan of a helpless Kim. The doctor watched as the tentacle began moving faster and faster inside of her. He knew what was coming next.
