Last Night's Experiment with My Husband

I've always been fascinated by the technical aspects of sex, so last night my husband and I decided to explore a new kink we read about online. We set up a camera on our bed before we began, aiming for full coverage of what was happening between us. To start, he blindfolded me, then tied my wrists together behind my back with silk rope, securing it to the headboard. He then proceeded to lubricate himself and entered me from behind, his penis slowly penetrating my vagina as I tried to gauge where exactly his movements were from by feeling for his body heat and muscle tension. We kept a steady rhythm for several minutes until he began alternating between thrusting quickly and pausing long pauses, forcing me to anticipate when the next motion would come. After what felt like an hour of this intense play, my husband untied me and we switched positions, him blindfolded while I had control over his body with commands and direction. This time, I took a strap-on and wore it for him, the dildo being slightly longer than average. As I thrust into him, he squirmed beneath me, trying to anticipate where I'd move next in his darkened state. The raw sensations were overwhelming, my husband's muscles clenching as pleasure coursed through them; the slickness between us growing with every motion. We explored this dynamic for another hour or so before concluding our experiment satisfied but wanting more.
