[Miley]

Watermelon juice breakfast
insisted on a day at the beach
with your love.

Unpacking wet towels, the zebra mussel cut Had to google "zebra mussel cut" and then this stanza became incredibly clearer for me. Otherwise I would never associate zebra with the beach ha. though some how zebra resonates with sunburn, not only because a sunburnt zebra is a popular joke punchline, but because of the shape of "peels" relative to the zebra stripes. Also something between the zebra stripes and the watermelon stripes. Zebra is just a strange word, and such an exotic looking animal.
shifts your weight to the left foot
as sunburn peels your neck.

When she walks in the room,
headache corkscrews the wine  I see a sort of symmetry here wherein each stanza the inanimate thing gets like... anthropomorphized (not the right word but hopefully you know what i mean) via its verb, breakfast insisted, cut shifts, headache corkscrews. This last one is my favorite but also the one that took my the longest to wrap my head around, as in I had to read it twice!
and you pour a glass alone.

My impression on this poem is of a beach day amongst 2 "lovers" perhaps a holiday. The last line reveals that there is trouble at paradise, though the middle stanza hints at it. Sometimes on holidays there are all these small inconveniences/irritants in this case that can make a sour mood soure, The fact that your supposed to be having fun makes the miserable day even worst!
Sorry I dont have much critical to add. I guess my inclination would be to switch it from "your" to "my" but that's just my intuition on it. Maybe  "insisted" in the first line works better in present tense as "insist"  

The line "with your love" is maybe a little flat comparatively but then it comes across as more of a workhorse line..
