Seeking advice: teasing methods without unlocking

This might be a bit unusual, so let me clarify. As I noted in my Hello World post back then, it was actually my suggestion to formalize our FLR (which we were already somewhat doing) and bring in male chastity/orgasm denial. My partner—now officially the keyholder—and I always strive for open communication. However, she wasn’t entirely clear on why this mattered so much to me or how beneficial it would be for our already solid relationship. I did my best to explain from all angles (her perspective, mine, and ours), and she agreed that the FLR wouldn’t disrupt too many of our existing dynamics. When it came to male chastity and her “ownership” over my genitals, she wanted a trial run first. We set aside one month to test the concept. Over those weeks, she really grew fond of it, and by month’s end, she was eager to keep going. How everything went so smoothly is a tale for another time… But there was a stipulation if we were to continue with male chastity/orgasm denial. She clarified that she finds the idea very appealing: removing my penis from the sexual equation entirely while still keeping our sex life healthy and mutually satisfying for both of us. She also promised that I wouldn’t be cut off from all orgasms right away; instead, it would be a gradual shift over time—perhaps through the rest of this year or so. If long-term results aren’t great, we can always revert to “normal” MC / OD. At first, I felt some hesitation but also arousal just thinking about it, and I accepted her condition. With that lengthy background out of the way, I hope my question is clear. Knowing how playful and creative she is, I’m confident she’s already brainstorming fun games and teases to help achieve this goal while enjoying herself in the process. Still, I’d love ideas and suggestions I can bring to her table. Has anyone here done or tried something similar? How did you manage it? What are some effective teases that don’t directly involve the penis? Any other thoughts on this? Thanks.

Staying locked while giving oral satisfaction suits me quite well.
