The clue!

Rob stopped running for a moment as he noticed a big white arrow pointing down at the side of the building. Rob had never noticed this before since he had his head down the first time he ran the track and no one in his party had thought to look in the direction that they came from. The answer was in front of them the whole time! That arrow must point to the next clue! I get it now. You had to run the track so you could turn at an angle to see it. Rob figured this was also a way to trick the students into exercising as well. But how did Rachel see it? Poor Rob still hadn't caught on that his student was just messing around with him to keep seeing him run naked. He merely found this clue by coincidence but Rob didn't think too deeply about it. For now, he sincerely believed his student led him in the right path.

He turned to the two girls on the other end of the track, he was not close enough to see their enamored expressions at the sight of Rob's nudity. "Hey, girls! Look behind you!" Rob was trying to turn their attention to the arrow on the side of the building, they were so close to the clue. Unfortunately, the girls were too far away to hear Rob, he wondered if he could gesture them over to the next clue. "Look at the arrow! Behind you, on the side of the school!" Rob began jumping up and down while waving his arms about to get their attention. He thought that the girls couldn't see him properly but the truth was they could see him all too well. The girls just stood there and giggled at the sight of Rob jumping, waving, and pointing while totally naked. He looked adorable. Neither of the girls wanted to look away from their naked teacher completely embarrassing himself.

Not seeing the girls react to him pointing towards the building, Rob saw no other option but to sprint up to Rachel and Lisa to tell them to their faces about the clue. Rob continued to pump his arms right up until he nearly passed out before them; he gave his fans quite a show. Rob was exhausted, covered in sweat, and nearly out of breath as he used the last of his energy to approach them. He bent over putting his hands on his knees as he panted for air. The girls took in the sight of him, finding Rob to look pretty sexy in a sheen of sweat that made his naked body glisten in the sun. "I found...the next clue..." Rob panted. He pointed to the building. The two girls reluctantly turned away from Rob to look at the school. They were astonished the moment they saw the arrow.

"Oh my gosh! How did we miss that? We just came from that direction!" Lisa was mentally kicking herself.

"Well, you just gotta keep your head up is all." Rachel was still covering for the fact that she didn't know anything. She was just as surprised as her friend and teacher at the appearance of this new clue.

"You were...you were right Rachel..." Rob kept panting. His hands still on his knees as he tried to catch his breath, giving his students the full monty. He was too focused on the clue to think about his current modesty. "Now... be a good girl...and fetch that clue...while I..." Rob's knees caved in as he fell forward softly on the grass face first flat on the ground.

Lisa let out a short laugh, "You did well Mr. Jenkins," she knelt beside him on the grass and ruffled his hair as she looked up to her friend "Rachel, can you go over there and see what that arrow is pointing at? I will stay here with Mr. Jenkins to make sure he's alright."

"How come you get to stay here with Mr. Jenkins? I helped him figure it out." Rachel pouted.

"Oh yeah, how did you know he would see it by running the track again?" Lisa already knew that Rachel was bullshitting Rob with that lucky guess and she knew she didn't want Rob to know she was just playing with him.

"I'll go check it out." Rachel walked away dismissively. Rob was too tired to follow the conversation so he just shot Rachel a quick thumbs up with his face still buried in the grass.

As Rachel walked off Lisa started stroking the muscles on Rob's back. Once she got her fill of that, her hand went down a little lower and she patted him on the butt. Rob would have normally stood up or batted her away but he just didn't have the energy for either after running the track twice. Man, I have to build up some more stamina. Rob thought.

As Lisa began stroking Rob's bare bottom Rachel came back carrying a note and an piece of Rob's wardrobe looking chipper. "Hey, I know where the next clue is!" Rachel whispered into Lisa's ear so she wouldn't alert Rob. "and I have an idea."
