My opinion on Leslie is that by this last update, she's ready. Breadman is fully entitled to write the game how he wants, but I'm simply critiquing based on that writing. Leslie's emotional and mental headspace has her unapologetically seeing her relationship with Jon as a woman first and a mother second. There's no justifications, excuses or rationalizations now for her sexual attraction, she enthusiastically fellates him and eagerly drinks his cum. She grinds on his cock until she orgasms. She fondles him and lets him fondle her. They talk and flirt like a sexually active couple, sleep together and shower together.The question of crossing that line is mostly framed for her in a romantic way rather than a taboo way. She's so far into it that she's come around to realizing she should be polyamorous with every other woman. Lilith got her to flat out say she wanted to have sex with Jon, that it'd be good, and it would be emotionally fulfilling.
At this point, her withholding until v0.10 feels artificial, unfortunately, like it's being dragged out when there's no real reason to. There needs to be some narrative obstacle introduced to further justify her reservations. Which, I'd be fine with, tbh. I like a slow burn if it makes sense. Maybe Jon's father finds out, where he calls her out on the situation being strange from an outsider perspective would be a big enough bit of friction to slow it down logically, and she has to come around to going after what she wants, damn the consequences. But otherwise, this is in the danger zone of being dragged out, and I really don't want that.
