Here is a challenge for couples (M/F).

The things that you will need for this challenge: chastity cage for him, bed restraints, rope, 2 vibrators, blindfold.

So the women will be tied on the bed using the bed restraints laying with her back on the bed. She must be completely naked and will be blindfolded as well. The guy will tie on one of the vibrators on the inside on her leg with rope, putting the vibrator on her clit.

The guy must be in chastity and will lay next to her on the bed. The guy is only allowed to watch his gf/wife, so no other porn or other stimulation. The guy will be using the other vibrator on his cage and balls to make himself cum while watching her squirm on the vibrator.

Only after the guy will cum whilst being in chastity, he's allowed to untie her and stop the vibrator. So she is in wait and maybe forced to orgasm multiple times until he "saves" her.

I'm curious what you think about this challenge!
