Exploring Taboos with My Partner

My partner and I have always had a strong connection, but lately, I've been feeling a pull towards something more taboo. Last night, we decided to explore our fantasies in ways neither of us had before. It started innocently enough with some playful teasing and role-play, but it quickly escalated into something much more intense. As I took on the persona of an authoritative figure while she played the part of a student who was eager to learn, there was an undeniable charge between us. The tension built as I tied her hands gently above her head and whispered instructions in her ear that made her shiver with anticipation. We both knew the line we shouldn't cross, but it felt exhilaratingly close. As we delved deeper into our fantasy, every touch and word sent pulses of pleasure coursing through me. The sensation of her body responding to mine was intoxicating, and I found myself pushing further than ever before. Despite the physical release that followed, a part of me can't help but wonder if there's something unhealthy about this newfound exploration. Is it normal for an adult relationship to include such intense role-play? Am I overthinking it, or should we reconsider where these boundaries lie?
