Go into the boy's locker room
From Create Your Own Story
One of your male students was in the shower, his hands held his average sized dick in his hands as he mastubated roughly. His eyes were closed and his lips began to moan your name. This made your underwear begin to feel wet to your suprise. You watched as the teenage boy blows his load onto the shower floor, water instantly washed it down the drain. You licked your lips and spoke. "You should keep that under control"
The teen turned around quickly, embarrassment showing on his now reddened face. "Uh mrs...uh" he studdered uncontrollably.
You quickly looked around the locker rooms, making sure it was completely empty of any other students. Then you stepped toward into the shower that the student still stood in. He stared as your shirt got soaked from the spraying water of the shower. "Not this dream again..." he groaned.
While shaking your head you smiled and said. "But this isn't a dream"
His lips made an O shape as your hands grasped his now re-hardened cock.
