The upside for you is that your husband will be very obedient and Do almost anything for you to make you happy. All that in hope for a reward( release)
You can use a vibrator on his cage… he will basically have a ruined orgasm… so give him a couple of minutes and do it again… and again until he is empty - he will still be horny since he hasn’t had a proper cum…. But you’ve emptied him!! Haha!!
