That is weird since the sister was willing to take clothes off in front of Bill but somehow the teacher finds it too difficult to give the papers. Another game dev bullied into cringe.
Although, the game is great and don't take my criticism too strongly. MC can not double penetrate all by his lone self, which is why those scenes are rare in these games. My sadness is simply because this means there would be no double penetration content in this game either, which is such a shame since the art is really well done and you would have done a great job at making a scene like that.
Best of luck with the game, and I recommend trying to get it to steam as well if you can. Despite what I have said above, I give this game at least 4 stars, and that too only because I do not like that MC is retarded. He can have all the girls, but he is still retarded. If he wasn't I would give it 5 stars.
