OMG I *love* this! So teasing, and I love the banter between Sirius and Lily. I don't often really click with Sirius, but this totally worked for me. Boy, did it work. And, hilariously, when I was a student, my boyfriend's best friend DID have a motorbike and he DID occasionally take me for a ride and claim he was warming me up, LOL. There was something slightly wrong with it so that if he didn't keep tightening a certain nut or something, the vibrations were really terrible ;)

Lovely, playful stuff!
