I had a thought earlier. Imagine two switches fucking with one on top absolutely plowing into the other in a mating press and the other is in absolute bliss and is barely able to form any coherent thoughts.
But with what coherent thoughts they can form they have a mischievous idea, and so they pull the dominant one into a kiss so their faces are closer, and when they both pull away the submissive one whisper's the other's trigger word to make them cum instantly. Sending them from a 6 to a 10 in seconds. The submissive one laughs about it and the dominant one gets a bit flustered but keeps fucking them, even rougher now to prove a point even though they're a bit sensitive from just cumming.
Then, once the dominant one regains composure, the submissive one does it again. It turns into a repeated cycle until the dominant one isn't feeling so dominant anymore and is whimpering and bordering on crying from how overstimulated they are. They finally try to pull out only for the other to wrap their legs around them and smirk. Telling them they aren't done yet, making them keep fucking them and telling them exactly how to do it.
Continuing to overstimulate them as they fuck, abusing the cum trigger until the one on top can barely move. And when that happens the other just pins them down and rides them instead, still abusing that cum trigger until the once dominant one is the one who can't form a coherent thought.
