I said that I was looking forward to your game a month ago when I saw the sneak peek on Reddit. I'm impressed with it, but I do have some complaints about it that hopefully can get fixed to make the game even greater. 

1. First, I feel like the game needs a bit more explanation to it because it has so little that it becomes confusing; things just happen too fast with little to no explanation, like with the coach's pregnancy. Then who spread the rumor of the MC's dick? Because we are led to believe he is a virgin, and then the first time it is mentioned is with Kimmy, which just so happens to be his first sexual interaction. The story just seems to be going by too fast and doesn't let anything just sit, which can be good to make sure things don't drag, but in this case it's just too short.
2. Secondly, I don't think having to choose between Ms. D and Elise is a good idea; I feel you could have just had both happen, especially because they both were kind of being built up, and then you could have had the coach show up. 

Now onto the good about the game, I like pregnancy stuff and impregnation, so it's awesome to have here. I also like the character models, and I love the animation and bits of jiggle physics in them. I like that it is only the MC having sex with all the girls.

Just make sure to never add NTR to the game, please. Also, even though the game is straightforward, maybe having a guide/ walkthrough would be nice, like to make some scenes and the secret images in the gallery easier to get. This seems like it will be a harem game, so don't make the mistake of having one or two girls more important than the rest; have all the girls end up feeling special if you want the game to be great. 

All in all, I had fun with your game and look forward to more from you. Also, you don't have to listen to what I say because, at the end of the day, this is your game and you should make it exactly how you want.
