Harry's mind locked.
For a very long time.
This was great use of imagery, I can imagine feeling the same way. Someone as incredible as Hermione wanting to not only share her secret feelings (something I can sort of see as a quid pro quot), but actively wanting to test them out with him. A week previous he would have freaked out far more, his best friend, a girl he was embarresed to be attracted to because of a precieved taboo, wanted to be actively sexual with him, plain old Harry. That would lock up anyone, even with a week of sex under their belt.
Personally really hoping herm becomes his wife, but enjoying the story thourally in any case.
