That is a group game. The description mentions multiple players. However, like Alicia suggest, you could make it a 2 player game. I doubt that game will go over very excitingly as a two player game though. Lemme see what games I can find for you. Gimme a sec. Some good 2-player only games.
101 Nights of Great Sex (Decent. Very focused on sex.)
Sex Casino (Never played it, but I've been told it has a lot of variety. 2 Player)
Bondage 101 (If you are interested in bondage, this one is fun.)
Fetish! (Exploring the world of fetishes while playing with your lover. Not a half-bad game.)
Those are the best out of the "Love games" section in my opinion. If you have questions about 101 of Great Sex or Fetish!, I've played them both and can answer them.
If you and your lover are looking for a more romantic-type game, Discover Your Lover (EF doesn't sell it) is the most highly rated game I can recommend. It brought the boyfriend and I really close together for some really passion, loving sex. It was more about the relationship and romance than the sex. We loved it. It's our favorite one.
(I'm totally a board game nerd. Ask if you have questions!
