Monster Science Experiment

This is your lovely day each day, talking to and watching monsters. You are tasked with studying them and watching them as they are in your lab. But since you love to fuck and monsters seem to love fucking as well, you slide it deep into the ass of several of the subjects you were sent to take care of. Nice! You also get to see how many more monsters you can get if you are a good care taker which means more monster pussy to fuck.
