This is absolutely terrible. I am not mocking anyone's fetish here, but it's so obvious that someone took 'base images' and drew upon them with hardly any skill. There is also some very terrible cutting and pasting going on there. The bases are also very inconsistent.
That said, seeing that awkwardly added bulge and the fact the girl says she feels something poking her, I think that the other girl is actually futa, so I added the tag. (Kinda new to this, but I did read all the guidelines... But if I still did something wrong, tell me or just correct me.)
