Im looking for a NTR game (i don't actually remember if the whole game is NTR or if it's avoidable) where the main character ends up in prison, while some criminals (i think they're criminals, could also be just people blackmailing him) send him videos and picture of them having fun with his Girlfriend. I think he got in prison to pay up a debt, and the condition was to spend time in prison while they could do stuff to his GF then send it to him.
