FOUND! specific fic, wincest time-swap where current Dean and younger Dean switch places for a day

[candlejill]

Originally a one shot and then a sequel. I can't remember what the first fic was and what the second was but I'm looking for two specific fics where S/D are already in an established relationship. They fall asleep at a motel but when Dean wakes up he finds that he traveled back in time to a younger Sam. It's before Sam ever told Dean he liked him but he talks to older/current Dean about it. It's younger Sam's first time with Dean.

In the other fic younger Dean (17?) is swapped to the current time. Sam finds him at a bar and brings him back to the motel (I think it's a little BDSM, some spanking). This fic is younger Dean's first time with Sam.

So, overall, one fic tells current Dean's experience of the time swap and the other fic is about older Sam's experience with younger Dean.

I think it's on someone's tumblr and I don't know if it was ever posted anywhere else. It's driving me crazy. I tried searching the tags and googling and nothing comes up. Any help would be greatly appreciated!
