im sorry fam but to be honest...
you do NTR/cuckolding.
you do it like, most of the time actually.
here? well, solid voyeurism but wouldnt be crazy to think the characters had some chemistry so i would say Ntr.
Not coming home: clearly NTR, like im 100% shes a wife
Dont ride alone: solid voyeurism with a 30% of ntr, depending of how you felt as a viewer with all of it, it makes it or not ntr (because ntr plays more with both couples, not couples and basically as long as you feel bad and jelous or something like that, it enters the category)
nanako is no good: clearly NTR-like thumbnail plus even though there is no expressed relation betwen the heroine and the viewer, the start is also ntr-like, that kind when they send the mc proofs of the ntr so, This one is a Maybe NTR-cuckolding.
life line headshot: solid voyeurism barely 10% chance of ntr
the elevator: i think its a solid not Ntr.
Sealing the deal: atleast a double to triple NTR. the heroine to the minion, the minion to his wife, and if we take the heroine's word on other way then from the minion's wife to him. also, one cuckolding to the minion because the heroine had a thing with other person and sent him spicy photos.
Last minute apology: 100% NTR
Madame thunder shock: 100% NTR
she sent me milk: its difficult... but i would say, it is a 50/50
so, atp youre an NTR gore artist. youre more near to ratatatat than to maplestar if you get it
