S&M Enchanted Bed Bound Restraints

Wasn't sure the under-mattress strap would actually hold, but it doesn't budge even when things get vigorous. The adjustable cuffs fit both of us comfortably, which is rare. Setup really did take seconds.

Slid the connector strap under our mattress in about ten seconds and it hasn't budged since. The dual wrist and ankle cuffs adjust easily enough that we can both get a comfortable fit without fiddling.

Wasn't sure these would stay put, but the strap under the mattress hasn't budged once. The cuffs adjust tight enough to feel secure without pinching, and cleanup is quick since everything wipes down easy.
