You should try the other works of the Author (SAMK) they all have that good tension & chemistry:

Still updating but here is a list for sexual tension I like I hope you find some good stuff!

I’m obsessed with it too, like sex by itself doesn’t appeal to me that’s why I find it hard to enjoy any Yaoi lately, I don’t really feel the chemistry or the passion, here’s a few I think have this type of tropes
Love or hate
Behind the scenes ( side couple)
Fate makes no mistake ( side couple)
Addiction (side couple)
Caste heaven ( very toxic)
Obedient heritage
Fuck buddy
For now that’s all I can remember, and don’t get your expectations too high because I feel like payback is just unmatched

I went and red December! The plot seemed a bit awkwardly written, idk if it’s just the translation or how it’s written overall but it kinda gave me brain cramps I still pulled through though for the sexual tension and omg their chemistry and smut scenes are so good! Definitely see the author from payback in it and it gets easier to read after a while. Also like the character so it makes up for the weird writing XD I can read almost anything as long as the tension and chemistry between the main couple is good

Just red half of me until the latest chapter and I love it!! This author really know how to create good chemistry and tension. This one is way more focused on the interesting plot aside from the romance compared to December and it’s well written too. I’ve noticed that this author tends to write more tough and feisty ukes which makes for a great tension and I’m a sucker for hate to love so this one is definitely my cup of tea! Thanks for the great recommendations (☆▽☆)
I’m absolutely obsessed with “payback” and I want to find similar yaois . The tension between the two is immaculate which makes the spicy scenes extremely erotic even if they don’t do much. I’m a sucker for tension and chemistry tied with good smut scenes that don’t feel repetitive (a bonus would be degradation talk). Anyone got recommendations? (Other yaoi with good tension that I like are mad dog and checkmate)
