[F28] I’ve recently developed a cheating kink

I want ti say this out loud, I’ve been afraid to say this for a while. It’s uncomfortable, confusing, and not something I’m proud of but I can’t help it. My biggest kink isn’t tied to a specific act or fantasy—it’s the idea of cheating on my boyfriend.
What excites me isn’t hurting him or ending our relationship. I love him with all my heart. The fantasy comes from the secrecy, the risk, the feeling of crossing a line I know I shouldn’t cross. It’s the tension between what’s expected of me and the temptation to do something forbidden.
Even just writing this confession out gives me butterflies, the thought of him reading this and not knowing that it’s written by the girl who sleeps next to him every night drives me wild.
I’ve got a much higher sex drive than him and Increasingly often when I’m alone what finally pushes me over the edge is the thought of someone slowly seducing me until I can’t pretend I don’t want it any longer.
