Some of these are fluffy, some are more smutty. Some are dialogue, thus the quotation marks. Ether way, Ship suggestions:
-Kamaniwa

Kinks: Morning after, marks, marathon sex?

-The top is awake, and admiring the marks they left on their sleeping bottom

-"I told you I'd fuck you all night long"

-The bottom trying to get out of bed and immediately falling and the top can't help but laugh

-"We just did it last night! How are you still horny?!"

-One of them waking the other up with a blowjob

-"I can't find my/your panties (or whatever clothing you want) "

-Them about to go for another round before getting interrupted (by a parent/kid/pet or whatever)"

-"Wanna have a repeat performance?"

-The bottom waking up to realize the top has a morning wood which is currently pressed against their ass

-"I can't feel my legs. You're gonna have to carry me."

Sorry for the late update. My little sister got diagnosed with an eating disorder (what kind, I don't know) which is bad cause she already has an immune deficiency. Her heart rate was dangerously low and she was rushed to the er. Now she's under surveillance and were slowly increasing the calories she eats so her heart rate doesn't go too high/stress her body. Needless to say, things have been crazy at home and I've been kinda stressed. I'm gonna try and write stuff still but don't be surprised if it's slow 😅😅😅
