First off, don't answer any questions, not even when the police show up. Their only job is to build a case against you. Then get a lawyer, and hope you get a light sentace for statitory rape. Also, don't forget you will now be registered as a sex offender.
Secondly, Diddy Kong Racing was trash for a racing game, no wonder she is crying. And N64 is 2 generations ago. Give her your DS with Mario Kart and Nintendogs. That should make her happy, maybe she will drop charges.
