I agree with you. Me, I locked up my husband's 4-inch cock permanently. However, twice a year (for his birthday and his party), I do as on the video, I release him, I wank him a little and I put him back in his cage when I decide even if he has not squirted . He is very frustrated and I laugh. But he thanks me anyway and I love it. I have a lover who makes me come. lol
If you ever bore of his hardon and want to get rid of whatever hardness is left, just add cold. Ice, water, frozen water bottle and it will shrink up. He will fit better afterwards and it will also calm him down for you.
I enjoyed my marriage so much more when we had this type of relationship. She has since gone 100% vanilla and used my previous kinks against me. Has threatened to put me to her family etc. and not in an erotic way at all.
