There is something you need to know...

"... and I know it is a weird time and place to do this... And I know you probably won't believe me at first... But I need to tell you this."

And you do. You tell her about the Rulebook and its miraculous power and how you found it and how the world was before you did; you tell her what you felt in your old life and what you did to address those feelings. You see your girlfriend making an effort to keep her expression neutral. Frankly, you are happy enough to treat the fact she did not run out of the room screaming for help as success in itself. When you have said all you wanted to say you take the Rulebook out. "I know it all sounds crazy", you say. "But tell me just one thing you can see that you want changed and you'll see what I mean."

Wordlessly Diana crosses the room and steps out onto the balcony. Unsure, you join her, still holding the Rulebook, hoping that she is actually looking for something to change rather than thinking of ways to escape you. Although you have other pressing concerns just now, you notice how perfectly your room is placed; you are on the second floor but the beach feels to be practically right under you, with the pool and the terrace to the side. Neither of you really registers the fact that you both are still fully nude; although most likely any observer will assume you are being punished, if anyone bothers to check your exposure will land you in a world of trouble. Fortunately the adjacent balconies are empty right now. You are watching your girlfriend out of the corner of her eye so when she moves you face her readily.

"This is a lot to take in", she says. "Sorry if I got you worried. I know you well enough to know you believe what you are saying and if somehow all this is actually happening you should know I would not judge anything you did or will do for a moment". She grins, presumably sensing the relief you are emitting in a near-visible spectrum. "Also, much as I hate being spanked, the system works, whoever put it there. We do not get punished without having done something wrong. Maybe we should fine-tune it, but that can wait. So let's write something new and fun in that book and if all of this happens not just in our heads we can then decide together what to do next". You grin back at your girlfriend. "Sure", you say. "But I've had my turn. Today you write what you want to."

Diana does not fight this point and takes the Rulebook happily enough. She initially tries to balance it on the balustrade but decides against it and puts it down onto the coffee table instead. You left a pencil between the pages, which Diana starts to write with after only the slightest hesitation. You feel the by now almost-familiar sensation of something changes moments later. Involuntarily you blink.

When you open your eyes, the change is not too major, but nonetheless immediately noticeable from where you stand. Every man on the beach is now stark naked. Any item of swimwear your eyes can find is covering a female body. Or at least meant to be - you see bikini bottoms discarded on a sunbed. On the same sunbed their owner is on all fours, sticking her bare bottom out. A fully nude man is whipping her with a belt; his semi-erect cock swings each time he delivers a stroke. Although you are not the one who wrote the rule, one of the very first rules you made is still very much in **** and tells you what exactly happened. To be fair, you could have worked it out yourself as the change is not overly complex. Compulsory nudity for adult males is now the long-established expectation, but limited to only beaches and pools - even in a pool-side cafe everyone is dressed as expected.

Diana steps up to your side. Her self-control has always been amazing, but you can see the shock of confirmation on her face. Still, she gets herself together faster than you would have expected. Certainly faster than you managed when you first came to realise the power in your hands. "Well, that was part one of the plan", your girlfriend says. "Are you sure you want me to do something on my own without even checking with you now?"

"Yes", you answer simply with a nod.
