He Decides When She Finishes
Intensity level: Adventurous
He controls all stimulation, stopping and starting, until he decides to let her over the edge. She surrenders the timing to him.
How to try this
He takes full control of all stimulation, hand, mouth, toy, whatever he's using, and starts bringing her to the edge. When she gets close, he slows down or stops. He repeats this until he decides she's ready, then lets her go. She gives up control of the timing entirely.
Why couples love this
Surrendering the timing of your own orgasm requires real trust, and that vulnerability is what makes this so charged. When he finally decides to let her finish, the release carries the weight of everything he made her wait through, and it hits differently because of it.
