I would like to share a teasing game with you.
very simple:
the sub is lying on the bed, face down. on his back, where he cannot reach with his hands, you put a glass full of water, so if he moves he drops it.
then you start teasing him. punishments for spilling water and/or dropping the glass are up to you.
I once did it to my gf. she lasted about 1 minute :)))
if you want to push it further, do it on her parents' bed, where she has a good incentive not to leave the bed wet.
and for the kinky ones: use boiling oil instead of water
