When I Crossed the Line with My Partner's Consent Boundaries

I met Jane when we were both in our early twenties. She was my first and only partner back then, a beautiful woman who always had her guard up but slowly opened up to me. We dated for three years before moving in together. Her one non-negotiable rule has always been about respecting her consent boundaries: if she says no, it means no. I've mostly respected those rules, though I've pushed them a bit sometimes by teasing or suggesting things we both know aren't on the table. But recently, while at a sex toy store together, I convinced Jane to try out something new and sexy that looked like fun. We brought home this fancy vibrating harness with multiple settings for every kind of pleasure. That night, after a lot of talk about trying it, I was really amped up. The energy in the air felt electric as we got undressed and started to play around with the toy. But soon enough, the moment turned heated, and I began pushing Jane's boundaries by suggesting things that she had previously firmly said no to, like being restrained or blindfolded. The way her body tensed up told me she wasn't into it, but I kept going, pressing my advantage. Despite her clear discomfort and saying 'no', I didn't stop because I felt the thrill of crossing that line was too intense for me to resist. I put on the harness anyway and started to thrust into her. Her body responded in ways I've never seen before, wildly erratic movements, gasps of shock intermixed with pleasure. I kept going until we both climaxed, but afterwards, Jane seemed shaken and distant. She didn't talk about what happened for days afterward, and when she finally did bring it up, the tension between us was palpable. I feel awful now for not respecting her limits that night, but the allure of pushing them just felt too strong to ignore in the moment.
