Talk to the girls.

Lisa blew Rob a kiss as he trotted over to the window still cupping his junk. Thankfully the girls could only see him from the waist up once he was close enough to open the window to talk to them.

"H-Hey guys," Rob was nervous. He thought he would diffuse the situation with small talk "lovely weather we are having today."

"Hello Mr. Jenkins, always a pleasure to see you." Lisa's cheeks turned slightly pink as she held a conversation with the naked teacher she had a crush on.

"As lovely as the weather is, shouldn't you at least have some pants on Mr. Jenkins?" Rachel added.

"Look, girls, its a long story as to how I ended up like this but would you be so kind as to delete those photos? I would be really embarrassed if those were to get out." Rob pleaded.

"Don't worry Mr. Jenkins," Rachel smiled "these are for our viewing pleasure only."

"P-Please..."

"Well, tell you what Mr. Jenkins," Lisa leaned in closer through the window to look Rob straight in the eye. "Tell us the reason why you are naked in the chemistry lab and we will decide what to do from there."

Rob didn't want to stay too long in one place. He had to get back to the scavenger hunt to find his clothes before the other students found them so he gave Rachel and Lisa a brief recounting of today's events; starting with 'volunteering' for Ms. Doyle's class and ending with his role in the scavenger hunt. Both girls were enraptured with Rob's story, especially the part where he ended up naked in the halls. This was a good opportunity for them.

"Poor Mr. Jenkins," Rachel leaned forward and wrapped her arms around Rob's neck for a hug. She nuzzled his cheek "that must have been so humiliating." Lisa also bent forward to wrap her arms around Rob's torso where she rubbed her face against Rob's bare chest.

Rob blushed once again as he patted both girls on the back, "Y-Yes, thank you girls. Your sympathy is appreciated." The girls were actually not as sympathetic as they appeared to be. This close to their favorite teacher they were able to see Rob's penis with just a glance downwards. Both girls exchanged a quick look at each other smiling with satisfaction as they still clung to their naked teacher.

"Tell you what Mr. Jenkins, I think we can help." Lisa rubbed her lips against Rob's nipple. The sensation was giving him goosebumps.

"Yeah, truth be told, we are also part of the scavenger hunt. We already figured out where our next clue leads. You can go there and we can come with you to make sure that you get what you're looking for." Rachel's stray hairs tickled Rob's cheek.

"Really? Thank you!" Rob felt like he finally encountered a silver lining despite fighting off the arousal he was getting from his students. He patted them both on the head, "Where does your clue say you should go?"
