This game is off to a good start as the sex scenes are very well done in my opinion.
But i have a few problems with the dialogs...
1. You should scrap some lines of dialog like (i'm paraphrasing here): i don't need my phone anymore, i'm putting it in my pocket.
Nobody i know speaks like that. It feels like what a robot or an alien would say.
You don't need to be overly descriptive with such mundane actions.
2. More of a nitpick here but it seems you're using "No doubt" a lot. I'ts okay if one or two people use it , like the MC and his roommate for ex, as it can be seen as a quirk but other people should use other turn of phrases like you're right, of course,for sure.
It could help differentiate the characters.
Anyways , good luck to you and your game
