Well I highly doubt they had an actual animal crawl up someone’s ass but a raccoon is a common animal that everyone knows what it looks like and how big it is so that’s probably why they used it as an example. In science they sometimes use weird examples but it helps give us a better visual and understanding for comparison.
For those who are wondering ‘how in the world did that dick even fit?’ here’s some interesting knowledge about the human anus...
A raccoon can fit into spaces 10cm (4inches) wide and our anus can take up to 12cm (5in) - roughy 7(18cm) to 8(20cm) inches wide. With that knowledge you can fit a grown raccoon up your ass.
Now I say roughly 7-8 in because some places say 7 while others say 8, either way that’s a big fcking number. And of course this is yaoi so things are exaggerated some. As for length well the biggest average dick length is 9inches so it’s not impossible for people to take something that large.
Could I be over analyzing something probably no one cares about? Yes, but I love storing useless info in my brain to give to others! Hope this was helpful to someone.
