“Now…” Dr. Kelsey said. “We do want to give Arnold as much privacy as possible through this demonstration, so the towel will stay on, but… can anyone tell me what makes a penis unique to a vagina?”
A bunch of the girls raised their hands. “Janet?” Dr. Kelsey called out.
“A penis must be erect before being able to sexually reproduce while a vagina does not,” Janet answered.
“Very good,” Dr. Kelsey said. “And how can someone tell if a penis is a erect?”
“It stands at attention at an angle,” Sally answered.
“Very good,” Dr. Kelsey said. “We’re going to demonstrate that now. Pay close attention to the towel and what happens once Arnold here is fully erect.”
Arnold eyes widened as he felt Dr Kelsey reach under the towel and brush her bare finger against his little penis. His face turned bright red while the others giggled. Dr. Kelsey couldn’t help but snicker.
Arnold could only watch as the towel slowly lifted up as Arnold became fully erect in front of his class. “Now, does anyone notice a difference?”
Hands shot up immediately.
