There isn't really a game called Interactive Girls. What is usually known under this name is a collection of entertaining programs by the Interactive Girls Club, some of which might qualify as games and most of which use the same engine:

Vida X

A simple seduction story starring Vida Garman, that tiger-eyed, sophisticated yet fun looking woman, as a fan described her. As in Immoral Study, you can make some wrong decisions, but it's mostly quite intuitive.

Teresa: House Guest

A similar adventure, this one starring Teresa May. Some of the decisions are less intuitive here. There is a, probably unofficial, Amiga port (1995) by the Unknown Amigos.

Jo Guest in the Milk Round

This is actually a real game, but you can cheat and jump right to the end. This is the only episode that was put on the index in Germany.

Camera Man

Record and replay a movie consisting of zooming and moving an image larger than the screen.

Erotic Byte

Sort of an electronic magazine featuring Jo Guest and two other girls identified only as Corrina and Tamara. There is no interactivity here, it's sort of like a PowerPoint presentation, but rather well done.

There's not much more to say about Interactive Girls. It's not a game in the strictest sense, though in some episodes there are some decisions that will influence the outcome. It's just a piece of light-hearted entertainment, no need to praise it, no need to sneer at it either.

Jo Guest

The Milk Round and Erotic Bytes were, by the way, are not the only connection Jo Guest has with computer games. Around 1996, she modeled for a few game ads in UK magazines. According to the Jo Guest FAQ, these games include Tetris Plus, Onside Soccer, and Assault Rigs, but the most (in)famous was probably the one for Battlecruiser 3000 AD, incidentally the only one I could dig up as well:

For Jo Guest fans Interactive Girls will be of special interest, for it was done early in her career, before she appeared in Loaded and became the sex symbol of the New Lads. Besides, The Milk Round is about as raunchy as Jo (who, unlike Vida Garman, never did hardcore) ever got.
