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.
As Sarah Jones walked up the front path to Matt's house she knew that tonight would be risky and dangerous for her. But she was so excited. Already her pussy lips were swollen and slick in anticipation of what might happen. She was glad she had an extra pair of panties in her briefcase.
Matt answered the door and as usual, his parents were on the way out to dance class for the evening. Matt politely made her a cup of coffee and they retired to the study.
"OK, Matt. We have looked at human sexual organs, the workings of the male and the female parts."
Sarah opened the text book to some cross section diagrams.
"We looked at male arousal, where sperm production takes place and how it mixes with fluids from the prostate to be released in the ejaculate during climax."
Sarah pointed to the male diagram but Matt's mind drifted back to being wanked off by his late 20's study tutor a couple of weeks back.
"Tonight, we will examine how that sperm and the female's egg are brought together during intercourse."
Sarah went on to explain that male sperm production was continuous but the egg was only released once every month at ovulation.
"As I told you, I take the contraceptive pill which suppresses ovulation but what would happen is the egg gets released from here." Sarah pointed to her belly.
"And it moves down the fallopian tube to meet the sperm released inside the woman's body during intercourse." Her finger moved down as she spoke.
Sarah suggested they went upstairs to examine that process. Matt swallowed hard but nodded.
"Shall we go to the guest bedroom?" Sarah asked.
