My Secret Engagement Night Surprise

I'm engaged to John and we've been together for four years. We were planning on being open and honest about everything, but last week, I surprised him by bringing a new friend into our relationship, an older woman named Clara who was also my partner's lover before. It felt like a way to share intimacy and experience something fresh with him. On the night of our engagement party, we did it right there in one of the bedrooms, John tied up, while Clara and I took turns pleasing him. The sensation of having another person join us, touching him in ways only I knew he loved, was electrifying. I guided her hands to places that made his body shiver, watching as she explored with confidence. When it came time for me to take over, the way Clara's fingers led the way and how John responded with moans of pleasure... It was more intimate than anything we've ever shared before, but also a bit taboo. I'm so conflicted about what this means for our future, yet can't deny that moment felt incredibly freeing.
