I wouldn't make fun of you! I've read some crack and it can be very bad, very uncomfortable to read. If it's done well, then it can be hilarious and sublime. I've read some of those and they are some of the most memorable fics I know. Yours isn't crack, though. It's very tender and sweet, and true to character. I still think that Severus wouldn't have had a lot of opportunities to kiss anyone, ever.
