Invisible to his sisters on his arm.

Matt took a deep breath and unlocked the door. He jumped back as the door flew open and his sister’s rushed in. He watched as the twin’s looked around the room not noticing him. He thought he was home free until Becca looked his way and sniffed the air. He saw her eyes look toward his waist and grow wide. Looking down he realized she was looking at the pen in his hand and cursed himself for being an idiot. He did not have time to react as his sister lunged at him.

Becca seeing the pen had realized something strange was going on. She new from the smell that her brother was in the room and using instinct she lunged where she felt he was. She felt her body contact something soft and she wrapped her arms and legs around it.

Ann had been shocked by her sister’s sudden movement and even more so when she floated in midair.

“Grab the pen.” Becca yelled as she held on to her now invisible brother.

Matt was trying to shake his sister off when the pen got pulled out of his hand. He tried to grab it back when Becca squeezed tighter and losing his balance he fell to the floor. He felt the point of something touch his back and looked behind him to see Ann wright something on him.

Not knowing what her brother did with the pen to become invisible Ann decided to be simplistic about it. Putting the tip against his invisible body she just wrote not invisible on his skin. Suddenly she could see him again.

Seeing the look on his sister’s face Matt realized she had figured the pen out and he tried to grab it from her.
