Maximized Intimacy with My Wife

For the past five years of our marriage, my wife and I have embraced a unique dynamic that goes beyond traditional roles. We recently introduced a new element to our intimate life: she likes to bind herself during sex, restricting her movement entirely while I take full control. The act begins when we both prepare, with me securing her wrists and ankles to the bed frame using soft but firm ties, ensuring she is completely immobilized yet comfortable. Her breasts are left exposed, pressing against the mattress as her legs spread wide. She gives a subtle nod indicating readiness, and then I proceed with deliberate movements, focusing on her pleasure points meticulously. As we engage in this act, there's a distinct sense of heightened intimacy; it's not just physical but emotional too. The feeling is both liberating for her, she’s fully trusting me, and empowering for me as the active participant. We explore different angles and intensities without hesitation or inhibition. Afterward, the experience leaves us in a state of contented exhaustion, yet invigorated. I’m curious if anyone has experienced something similar within their relationship and would be willing to share how they manage this kind of intimacy while maintaining mutual respect and trust. Is it common for couples to delve into such detailed control dynamics?
