Hot Mint.
Levi and Eren are showering together, as they often do. While Levi is rinsing off shampoo, Eren snaps open a new shower gel and pours a generous anount into his palms, waiting.
Levi: Mm. What flavour?
Eren: Mint.
Levi: Huh.
Eren: (Rubbing the gel into Levi's back) Is it good?
Levi: (blissful) S'not bad. (Pouring gel on Eren's shoulders)
Eren: Ooh, it tingles!
Levi: This could be fun.
They work the minty gel into each other's bodies. Levi gasps when the cool mint drips over a nipple. Eren melts under the intoxicating sensation of Levi rubbing circles into his shoulders, hips.
...
Levi: (grimacing in pain) Holy fuck!
Eren: Huh? (the gel reaches his groin) Urghhh. It burns!
Levi: No shit.
Eren: (discarding the showerhead) How is water making this worse?
Levi: Dunno, but we're getting the hell outta here.
...
A good few minutes later.
Eren: I'll throw the gel.
Levi: No.
Eren: Don't tell me that you enjoyed having your balls on fire?
Levi: No. But we'll save your bottle of minty hell. For houseguests.
