Gabriel looked at his teacher as she reached for a tissue. "What are you doing?"

"Just going to clean up?"

"Why, you know that semen is very good for your skin. If you wipe it off before it sets, it won't do anything."

Miss Long looked at the tissue. She pretended to hit herself in the forehead with her palm. "Well duh! How could I forget?"

"Besides, it's invisible. No one can see it, so you can just leave it there for as long as you'd like," added Gabriel.

"Of course, Miss Long. You're the expert!"
