European Tire Change
An European Tire Change is when you are fisting a partner (anal or vaginal) and have to swap hands due to fatigue. The key is not to ruin the flow by abruptly removing a hand, instead you insert the second hand while the first hand is still engaged, removing the initial hand ONLY after the second is in position (making it a perfect pit stop).
