Vanilla(ish) Cheating Recommendations

Hello,

Wondering if anyone knows any cheating hentai that have vanilla-like atmospheres. Doesn't need to have both the cheating and vanilla tags (since I've already done a multi-tag search and have read all the results). Here is an example of something that falls in this category:

• Leave It to Twilight by Esuke.

I'll also take hentai in which one of the characters cheats with someone who is a better person than their current partner and seemingly loves them more than their current partner. Here is an example of something that falls into this category:

• Craving by Hard-boiled Yoshiko.

Thanks!
(I'd also like to nominate a "Vanilla Chocolate Swirl" Tag for those hentai that fall into the first category or are tagged as Vanilla + Cheating lol.)

Imperfect Family (and its no longer cheating sequel Perfect Family) (book chapters)
My Neighbor Yamashita-san (book chapter)
Studio of Thorns (and book version with epilogue)
