When a girl must play and listen to music while masturbating with a dildo or vibrator. Usually to muffle the sounds of her agonizing pleasure but may simply be for her love of music.
Can’t wait to get home today and enjoy a little dilharmonic.

What is up with your sister? Always playing that music in the wee hours of the morning. She is enjoying the dilharmonic.
