Matt was 18 and falling behind with his studies and at risk of not getting onto his University course, so his parents enlisted a tutor for 1 to 1 additional lessons after hours. Miss Jones was late 20s and appreciated the extra income to supplement her junior teaching salary.
Next week Matt had read up on his homework as he had to. He had wanked himself almost every night thinking about labia, clitoris' and vaginal juices.
Sarah came in as usual and they settled themselves into the room and turned to the chapter in the text book.
"Now Matt, are you able to talk me through the female reproductive system as we planned?"
Matt nodded and mumbled "I guess so, yes."
"Good." said Sarah.
She explained that to make things easier, she had worn a skirt and no underwear. Matt gulped and his cock hardened in his pants. Sarah sat on a piano stool and lifted up her skirt right in front of where Matt was sitting.
"Can you start with the external features?" She asked.
"Labia majora?" Matt nervously said.
Sarah reached down and gently parted her outer lips.
"You can see I have shaved away my pubic hair to make things easier to see. And in here we have?"
"The labia minora." Matt replied.
Sarah licked her fingers and touched her wet lips.
"What else?"
"The clitoris?" Matt asked.
Sarah explained the clitoris' role in sexual arousal and as is to demonstrate she idly diddled it with her middle finger as she described how it brought on lubrication of the vagina.
"You might be able to see my lubrication, Matt. Can you?"
"Not yet, miss." he replied.
"Then why don't you have a feel. It feels quite wet in there to me. Go on, touch it."
Matt nervously reached forward with his hand and touched a fingertip onto his tutor's pink vagina. It felt warm and slick. With her encouragement he moved the finger around and at her entrance he felt the juices she had spoken of.
"Put your finger inside my vaginal sphincter, please Matt." Sarah instructed and Matt did as he was told.
Sarah explained how this part of the female anatomy guarded the entrance and could squeeze tightly. She demonstrated around his finger.
"Feel that?" Matt Nodded and his cock throbbed in his pants.
Sarah then guided him through sliding a finger all the way into her vagina. She made him curl a finger up to feel her g-spot and explained the delights it could bring to a woman approaching orgasm.
By now, Matt was firmly sat between his tutor's warm thighs as she guided him through a tour of her sexual parts in Matt's parents' front room.
"Can you put another finger inside me please, Matt?" Sarah asked.
Matt did as he was told and felt Sarah's tight wetness engulf his middle finger too.
"Feels tighter doesn't it?" Sarah asked.
Matt agreed.
