Here the wheel is set for three people. Every task says who does what, so nobody is left just watching. In settings you can switch between FMF and MFM and choose the heat level. It helps at the start, when nobody knows how to begin.
From our own experience, with three people the mood matters even more, because it helps everyone relax. Soft light or candles, music, a blindfold for whoever’s turn it is. Tasks can be changed on the go: if you know what one of you likes, add it. Most important, start during the day. A group chat with hints about the evening, and all three of you will be waiting for it.
