Sounds a little like sexie time XD
No, seriously. It sounds like you have been through a committed relationship and then either one of you ends up rubbish in bed and you don't want to be with each other anymore...
That's my portrayal of it anyway, haha
It is effective because it means they sopke so beautifully to each other it was like the music from a string instrument, a harp maybe, or a guitar. To speak to each other like this shows love and a trusting in each other.
