I have yet to play this avn,i have heard from others that this one is awesome and I'm definitely gonna love it,but some comments made me a bit concerned,like it's kinetic,not big fan of seating on back seat rather than driving my car,and then some old crush or li dating Bully of mc and not being in any relationship with a girl whom mc met 5 years ago and try to be intimate a bit.And then their is sharing content (just with females).
You said this isn't an avn with NTR,i won't judge you for your kinks,it's your avn,but are you sure about that? Since all this aspects looks like a perfect blender story for sharing/swinging/cuckholdry avn and nothing like romance, wholesome,i mean what could change when mc couldn't get a girl to date him even after being with her for 5 years,even a loser can score a nerdy chick if they would be friends for 5 years,then mc bully is dating his crush or whatever she is.
And then it will not even have harem in future,i mean this all is definitely heading towards the three forbidden letter.
It's your avn to make it like the way you want,but the plot and theme is completely different from what you are trying to create,it's complex but still i will try it to see how you will pull this wierd completely different plot off.
