Living up to your name, doesn't get more cultured than all the way through tentacle fucking. Does it count as all the way through if it started in the stomach then went out both ends?
Well, this has to be one of the most hilarious ways I've ever seen someone turned into a tentacle seedbed.
Clearly, INT was that cat-girl's dump stat.
Regardless, hot stuff. The only problem with it is that I wish it was longer and had more detail about what happened to the younger sister along with the two of them getting fucked together.
