Think about the love of your life, sweet innocent and beautiful who is also into you but you dont know that yet. Now think of the worst type of MAN you can think of and he manages to seduces and charms your girl. Now put those 2 together in the bed. You still have yet to confess to her and then one day you find her and that man you thought of going crazy in the bedroom behind your back. The image of her innocence just cracks seeing her doing obscene positions with a man that ISNT you. And the next day acts like she didnt just do 83 positions of the hidden leaf on her bed while you on the other hand feel betrayed and broken.
That's NTR
(In my opinion at least)
Damn... even im starting to feel sad for this imaginary guy i used to describe a scenario...
