At the Gay Sex Positions Guide, we define group gay sex positions by the activities—anal intercourse, blowjobs, or rimjobs—performed by three participants, which we'll refer to as participants A, B, and C.
In the rim train position, participant A gives a rimjob to participant B who gives a rimjob to participant C.
This position may involve more than three participants. The defining characteristic of the rim train position is that every participant, except for one, gives a rimjob; alternatively, every participant, except for one, receives a rimjob.
