Help me to find a story

Hello everyone, some time ago I read a story that I liked and I wanted to read it again but I can’t find it.

The story was about a young man who wanted to fuck his friend’s father and for that what the young man did was ask him for help with his science project, the young man asked him for a semen sample to analyze in class, the man initially refused but since the project involved his son’s qualification, he decided to do it, this story has no mc but there comes a time when the man decides that he wants to be dominated by the young man, there is even a chapter where the man is shaved, I don’t know if someone can help me find it I would really appreciate it.

I know what you are talking about, it was on Nifty but it might have been deleted by the author.

Thanks for replying, it’s a shame, the story was good and had what I like in a story “big sub small top” is my favorite topic

I think the name of the sorry is “how it all begun”
