I like the setting (your teacher inviting you to her place)
I adore the teacher's model. Face as well as the body. Really turning on.(big natural meaty ass with a minimal of celulite would be welcome)
The graphics quality is also excellent imho.
Actually I think this is one of the best pre-settings for what can become one of the best games if done right.
This just needs further quality and slow, realistic !!! (near babysitter level) storytelling like after several weeks the main character slowly engaging both with the daughter but even more with the teacher which ultimatly dominates and uses him as her fuck boy and tries to hide him from the outter world/others. Before that of course in a long story prelude the student should pick up works in/around the house, studying, exploring, overthinking and generally following the teachers quests/orders while also slowly being attracted to her. Again, it should be difficult to go further and further as both know the consequences of this being exposed. Throw in a naughty and dirty co-teacher which has latent but intensive lesbian realtion to the teacher (nobody noticing when they r doing it) and later visits them every so days for threesomes in the basement (after she noticed what is going on between the student and teacher and is introduced by the teacher) as well as occasional search warrants for the student where he gets the option to distance himself/take steps to leave the house (but ultimatly doesn't) and afterwards does everything to prevent others from taking him away from the teatchers place.
GIve it a monetary element which continuesly follows the story like the student getting money from the teacher (later for sometimes pleasing her) and being able to buy groceries/everyday stuff and later stuff to prevent going home as well as alcohol, light drugs, sex toys/clothings (oversized dildos,vibrators, penis pumps, anal beads, lubricant, you know the stuff).
I think the idea of the teatcher dominating him should be accompanied by her sexual desire to be heavily used (a bit of bondage and hurting her)
As for atmospherics I like the concept of this house being a bit isolated ( towards a mountain) and therefore being exposed to darker nights and thunderstorms. Perfect for a bit harder sexual stuff. It should definitly have some mystic atmosphere (electricity black outs, fog, warm fires/candles while) being alternated by sober modern soothing scenes.
Well, I could go on and on but this should be the vage narative/concept of this game as far as I think. I hope many will agree
