Hi Clouds
Thank you, I am always looking for feedback like this. The negotiation is the heart of this whole thing, so it means a lot that it's where you want more depth.
You're right that the boundaries can go further. More chapters are coming. There's a first pass already (how far the first time, the condom rule, and a broken rule that pays off later), but the granular stuff you're describing, specific acts, raw, creampies, birth control, the choice to let nature take its course, is exactly where the negotiation layer is built to grow. Of course a story cannot accomodate all aspects of the experience (without being very lenghty), but there is room for more.
And I appreciate the distinction you drew: the risk as the turn-on, not the pregnancy itself. That's a sharp line, and it lands harder negotiated up front than assumed. Thanks for taking the time to be this specific.
