Okay so admission time, that's not really why we broke up. The cadence of the story was just better that way.

In reality, we "broke up" (reduced the number of dates we had) because we were in a poly relationship and things were becoming more serious (as in, thinking about children and getting married) with her primary, which I fully support.

The books were after her recommendation, by the way, they did unlock a few new kinks (and reinforced plenty existing ones), and the sentence "I can barely recognise you (in bed)" was indeed muttered a few times, so I was mostly truthful, but you can see why the cadence came out better in the original comment.
