No problem with the category, it covers a lot of possibilities, but you ended too soon, should have got to the 3-way.

The moral turpitude exhibited does not attract me, but the story itself is worth reading.
Much better than the other comments might lead you to believe.
First of all, the female lead was playing submissive. The male lead, and the secondary female in the story, are playing dominate. The male lead is preempting the domination game of the secondary female, to what success is not evident in the story, but it looks good for him so far. The female lead is being tasked to "conquer" the secondary female using her wiles - which is either dominate or very submissive, depending on how it plays out.
The secondary female may or may not be primarily lesbian - assuming she is does not bode well for any subsequent analysis of the story by such an observer...
As for the category, it is just fine - " Married extra-marital fun: swinging, sharing & more" is all over this story. BDSM is the other obvious one, but seems to be too obvious this early in the story.
Lots more could be made of the narrative, of course but that may be for another day.

Story has some potential to go in a few directions !
Good start !
Not my type caught me thought cheating and punishment etc
Hope he handles it well when the lesbian laughs at his offer. She will have no interest in his y-chromo body and attitude. There are other well toned ladies in the class who won't insist on a threesome with a penis but will be more than willing to leave their sports bras at home.
