"They're blue this time!"

Rob's legs were shaking as he stood in front of a widely female class of 18 year old girls knowing something demeaning was going to happen to him again.

"Good day my senior class," Ms. Doyle addressed her students. "today we have an unusual exam. Now I say unusual because unlike most tests. This one is going to be a lot of fun! Please be sure to thank Mr. Jenkins for making it so by the end of class. Oh! And let's not forget Carol, our school secretary, who not only made this possible but she will be standing in on today's class helping Mr. Jenkins for this exam."

There was as short round of applause around the room as Carol joyfully dipped for a bow. Apparently Ms. Doyle liked to encourage young impressionable women to pursue a fulfilling career as doctors or scientists if they showed an interest in her class. As a result, she decided to help these girls' endeavors by providing get-together's with informative exams for her senior students. The situation Rob found himself in now was to test how well the girls could identify a muscle just by looking at it on a human body. That body of course, was going to be Rob's.

"Alright now let us begin," Ms. Doyle situated herself among her students propping up a camera in the front row between two desks facing Rob. "Ms. Carol will point to a muscle on Mr. Jenkins body, one of you just has to raise their hand and call it out. Remember, for those of you going into the field of surgery it is within your benefit to recognize these muscles on sight as best you can. Now Mr. Jenkins could you raise your right arm please?" Rob obeyed easily. This actually didn't seem too bad. Carol pointed to an area on Rob's arm and a familiar looking girl raised her hand from the middle row of desks. "Yes, Shay? What is your answer?"

"I can't give you an answer Ms. Doyle. You see, how can we identify which muscle is which if we can fully see it?" Rob began to realize he has seen this 'Shay' before.

"Of course, you are right Shay. Mr Jenkins, kindly remove your shirt please."

Rob froze for a moment of panic. Was Ms. Doyle going to have him strip in front of these girls?

"Mr. Jenkins! Get the lead out!" Carol shouted. Her voice reminded Rob that he was in no position to object. Rob shrugged out of his blazer and loosened his tie. Carol collected these discarded articles and placed them on the seat behind the instructor's desk. Rob proceeded to unbutton his shirt. As soon as he unhinged the last clasp, Carol yanked the material right off Rob's body leaving him bare-chested in front of an admiring crowd. One of the girls from the back row let out a sharp wolf-whistle that was answered by a small set of giggles from her neighbors and a light blush on Rob's face.

"Wonderful Mr. Jenkins! Now put your arm back up so Shay can answer the question." Ms. Doyle snapped a photo of Rob from behind her digital camera as she spoke. Why was she taking pictures of this? Rob thought. Carol, having no patience for Rob, hoisted his right arm up and positioned him into flexing as she pointed.

"Oh! That muscle would be the biceps brachii." Shay announced. Rob suddenly remembered where he has seen this girl before. She was at the Crack 'n' Sack! She saw him naked! She was one of the girls who grabbed his cock! The one he didn't know before.

"Correct, Shay. Though I suppose that was an easy one." Ms. Doyle smiled affectionately towards her student.

"Indeed Ms. Doyle, though there is no denying that her response was much quicker once Mr. Jenkins undressed for us." Carol gestured towards Rob. "Perhaps we should try mixing things up a bit by pointing out a muscle in a completely different area of the body."

"Agreed, I would very much like to delve into Mr. Jenkins lower half...his muscles that is!" Ms. Doyle flustered.

"Way ahead of you. Rob! Drop your pants immediately!" Carol yelled, meaning there was no room for negotiation. With shaky hands, Rob unbuckled his belt and unzipped his fly. Rob toed out of his shoes and socks as his eyes worriedly darted around the room taking in the eager expressions of his voyeurs. Rob took a deep breath right before he dropped his pants to the floor. The giggling from the back now spread to the front row as Rob stood before them in nothing but his underwear.

As Ms. Doyle snapped another photo, Carol quickly scooped up Rob's shoes and pants putting them with the rest of his clothing. "Oooh! they're blue this time." Carol was eyeing Rob's royal blue briefs with an amused expression thinking about the video she had of him chasing after his tighty-whiteys. "You know you are totally useless Rob, but I will say this about you," Carol reached out and grabbed Rob by the crotch "I do appreciate your taste in underwear. The thing about briefs, is that they put so much emphasis on a man's...package!" Carol rubbed her palm against Rob's front until he was nice and hard, forming an embarrassing tent in his briefs. Rob's pinked cheeks turned into a darker shade of red.
