The first story is about an affair between stepmom and her minor stepson, the second is about a girl and a beastman, and so on.

beside the two that is already translated, later there would be a pair of step-sibling, alien-human (and they're probably the most graphic one on the s*x scenes, but not graphic like smut; it's just described a few more sentences, in clear words, than simply hinting they done the deed from back pain. But honestly, the alien are still humanoid). And you shall not worry, the beastman part, IIRC, glossed over the bed action. That makes the "icky" CP a total of four. There is one pair that falls into a grey area since the female lead was rebirth-ed to the present time after she died, to a child body, and her spouse was basically waiting for her new body to grew up before they remarry; and their setting is ancient chinese, so you can imagine at what age.

the son the FL adopted slowly have feelings for her and even thought of f*cking her, judging from the other reviews, I can see that they would end up together, so I just dropped it there. It's a bit too nauseating for me to read, would've been better if she adopted him as her brother rather than son, then it wouldn't be so weird.

In the first arc, the son is the Ml. I kinda saw it coming since this is a romance novel and the FL didn't spend time with essentially anyone other than him and her family. The age gap is 12 yrs, still a lot, but I've seen worse. What irks me is that everyone treated them as a parent-child duo, even the FL. To have feelings for your guardian in such an environment is a bit... I know that she was his only 'family' and as an orphan he's supposed to have mommy issues, but still. For once, I would love to read a novel where the age gap of the guardian and the child is less and yet, they still don't have s*xual tension between them. But oh well, how would something like that catch the reader's attention?
