400. Another hundred completed.

To her new boyfriend's dark bedroom hollow,
Down the hallway a maiden did follow.
While sucking his dick
Thought, "When he shoots his slick
Stuff should I spit it out or just swallow?"

That one was inspired by the joke
Q: What's the difference between love, true love, and just showin' off?
A: It depends on whether your girlfriend spits, swallows, or gargles!"
