The Au Pair Society

Sweetheart Video has its Mother Lovers Society series and Girlfriends Films its Mother/Daughter Exchange Club, so Missa X turns a page and instead of swapping daughters poses stepmoms lending out their stepsons.

Initial gambit has the great MILF Ryan Keely sort of prepping for incest with her own kid by arranging for a society member to send over her college kid Nathan Bronson.

He's not very good at role-playing but tries to pretend he's Ryan's son, and they both cooperate at sex, with Keely enjoying being submissive. It's a strong sex scene and benefits from the novelty of the situation.
