Well, I came across this comment and almost died laughing:
The first time I stuck a vibrator in my ass, life was good until I turned the damn thing on, and then I yelped like a violated sheep because "ripped me a new one" couldn't begin to describe what it felt like.
moonflower_rose just pointed out another BRILLIANT line:
ill try taking it without the vibration and i can only get it so far in and the once i turn on the vibration BOOM suddenly the whole thing is sucked up into my ass.
ETA: Y'all have to read this post, too.
