Mattress Mambo 2 - Free

Mattress Mambo 2 - Free is a sexy game for couples.
Relationships are a dance--and as you get more comfortable in the relationship, you might want some more complicated steps.
Spice up your love life with a little foreplay. If you're stuck in a rut or just need to add something new to the bedroom, then this game is for you.
Included are predefined activities that ramp up as the game continues. Skip the ones you want, maybe laugh at some others, and have fun playing a game meant for the bedroom (and maybe a few other locations around the house).

Specify names, items on hand, gender, amount of clothes, and what you're up for. Then take turns taking direction for the allotted time.

This sequel adds a ton of new activities as well as the the ability to add your own.
The free version is limited in the number of activities that are available as well as the number of custom ones that can be added.
