Not wishing to be roasted by Capitan -
A pregnant Snape is a bitch, Far worse than an up-the-duff witch, But young Harry knows If he sucks on Snape's toes, The git will just whimper and twitch.
Then move up to nuzzle his prick, Give it a slurp and a lick. Snape comes in a trice, And plays fairly nice - At least till the babe starts to kick.
