Sorry it took so long but here are the recs for you! The majority of them are Eunhae and/or Kyumin with a very few exceptiions.

These first ones are shorter ones, like one-shots and stuff that are mostly just the hehe:

1.Sweat – Kyumin – one-shot by my favourite author Adriatic where Sungmin is a musical actor and Kyuhyun is his fanboy who lusts after him.

2.Lock your windows – Eunhae (with mentions of Kyumin) – again a one-shot by Adriatic.

3.The Lifeguard – Eunhae – Hyuk is the hot lifeguard at the local pool.

4.City Pool – Eunhae (sequel to the lifeguard)

5.Roadblock – Eunhae – Hae’s still in the closet and he meet’s Hyuk when his car breaks down and he’s determined to help pull him out of the closet.

6.Lust Or Love – Eunhae – Hyuk’s new to the neighbourhood and he meets a very attractive older man at the bus stop, slight pedo-hae. 

The following ones are longer, at least a few chapters long and contain a lot more actual plot (but still with good quality haha)

1.Caught On Tape – Eunhae – omg I love this one! (mostly because I think it’s still possible lol shh!) So it’s a few years since SJ ended/disbanded and Donghae comes up with an idea to regain popularity, by Eunhae releasing a tape.

2.When Destiny Calls – Eunhae – Hyukjae absentmindedly picks up a call one day and hears a stranger moan down the phone, it turns out that Donghae had misdialled the hotline. But the older (in this case Hae) keeps calling the younger afterwards even though Hyuk calls him a ert hehe and I love how their relationship develops.   

3.Wrong Number – Eunhae – inspired by NutellaCookie’s When Destiny Calls, but this time they’re the same age and Hyuk’s the one who misdials the phone hotline. This one’s shorter and has less angst, more in comparison to When Destiny Calls, but both are awesome in their own ways.

4.The Pull – Eunhae – everyone has a soulmate with whom they feel a “pull” towards when they meet and Hyukjae can’t wait until the day he meets his. But Donghae doesn’t think much of the whole concept of “the pull”. So both of their expectations of what happens when they meet their soulmates is challenged when the two meet in the flower shop Hyukjae works at.

5.Call Center – Kyumin (and later Eunhae too) – mostly story/plot but there’re some chapters and they’re really good. Sungmin is a telemarketer and Kyuhyun’s bored, they first meet and develop a budding relationship on the phone.

6.Admit it, you lust me – Kyuwook – the two have very different views on love and lust but are still together in a friends with benefits kind of way in secret, I can’t wait to see how this story’ll develop.

7.Obsessive, compulsive, impulsive – Kyumin – I don’t know if you read genderswitch but if you do or want to give it a try, this is a really good Kyumin one.

8.Taming of the Monkey – Eunhae (and later KyuChul) – one of the first fics I ever read and I still love it. Does get a little angsty but it’s nothing major. Hae is a teacher and Hyuk is his student who lusts after him. This fic made me realise KyuChul lol.

9.Five Night Stand – KyuHae – Kyuhyun is curious and this basically leads to ty hehe

10.The Hook Up – Kyumin – title says it all really XD This one's quite short but I put it with the longer since it has a longer sequel.

11.Hooked On You – Kyumin – (sequel to The Hook Up) This and The Hook Up has really good (and lots of it) but later on the story also develops more too.

12.Time On Call – Eunhae (and 2woon) – Hyukjae and Jongwoon work as phone operators.

13.My .(y) Babysitter – Eunhae – this one’s quite short but I put it with the longer ones because it has a longer sequel. One day Hyukjae’s mum leaves him at home with a babysitter (much to Hyukjae’s dismay who insists he’s too old for one, especially as his babysitter turns out to be a hot guy who’s actually a few months younger than him).

14.Hunting my .(y) Babysitter – Eunhae (with some Kyumin) – (sequel to My .(y) Babysitter). 

So that's all I can think of right now but there're probably more. If you want you can also check out my general Fic Recommendation List here, which I need to majorly update too: My fic recs
