YN has been dating Mark for a few months, and everything seems perfect. Mark introduces her to the Guardians, and the team is welcoming, until Rex shows up. His comment about Mark’s ex, Eve, stirs up feelings of jealousy and insecurity in YN.
Obsessed with Eve, YN finds herself digging deeper into her social media, but the more she learns, the more conflicted she becomes. The more Mark mentions her, the harder it is for YN to shake the unease.
When a moment with Mark leaves her confused and hurt, YN unexpectedly turns to Rex, the one person she never thought she’d lean on. But this time, Rex isn’t mocking her. He stays by her side, offering comfort when she needs it most.

Summary
Rex has always been Y/N’s best friend; he’s the one she gets into trouble with, definitely not acting like the hero she should when she’s with him.
Mark, on the other hand, is the sweetest, slightly anxious superhero boyfriend who’s never even thought about touching a joint in his life. So, when Y/N convinces both her boys to join her for one innocent little smoke session, things are bound to get... interesting.
What starts as a chill, stoned night of teasing and light tension quickly turns into something much hotter, as Rex and Mark find themselves competing for her attention. When the high kicks in, so do the desires, and what was supposed to be a smoke rotation between friends turns into a steamy power play for Y/N’s pleasure, with both boys eager to prove who can make her feel more than just lit.
Weed, two boys, and stoned YN who’s not getting enough from either of them.
This isn’t the typical rotation of Puff, Puff, Pass. This is a Puff, Puff... Smash.(TO CELEBRATE 420!! Happy 420 Y’ALL)
