That 'psycho bitch girl' looks like she could be a sweetheart, but has such a vicious attitude. Great contrast. The nude swimming area scene is amusing. I can imagine the chaste husband crouching in a clump of bushes while watching the other guy enjoy his adulterous wife.
The psycho girl looks like she's done well at 'learning on the job'. And I do rather like nude swimming areas ... a chastity victim can't keep his 'secret' from anyone there!
