Too small hallway with Ravenbutt

>Shenanigans involving a poorly timed growth spell and a too narrow hallway happen and you find yourself between a wall and a soft place
>More specifically your face pinned between a wall and the plump, grey ass of a very unamused Raven
>On the upside at least, she doesn't seem to blame you for this, your muffled shouts seemed to have gotten the point across that you were just in the wrong place at the wrong time at least
>Not that it changes your situation much, neither of you has any real room to move, and after your first few attempts to do so only resulted in a number of grunts, groans, pushes, shoves and two near suffocation on your end, you two somehow ended up wedged in there even tighter
>At least you have some room to breath now, even if having your head nestled between her buns leaves every breath smelling, and tasting, distinctly of her
>Still, it'll be a long two hours to wait for the spell to wear off, especially with her wiggling her hips every now and then, testing just how much give there is and inadvertently grinding herself against your face
>You're pretty sure it's just your imagination that she's doing it more and more often as time goes on

>"Nhg, this isn't working" she groans out, voice oddly husky after several minutes of grinding and wiggling, "Try, ...I don't know, are your hands free? Give me a shove"
>With nothing else to do, and growing increasingly lightheaded from the heady scent of her body, you manage to slide your hands between her asscheeks and the wall and push
>Only to have them sink into the soft, pliant flesh, her rear not budging an inch despite your best efforts
>Not wanting to give up yet you reposition them and try again, and again, and again
>Roving your hands up and down her cheeks, grabbing great handfuls of her buns and thighs each time, looking for the one place to shove, only to have that ass stubbornly refuse to move
>At least until she suddenly pushes back, snapping out a "I said shove, not grope!" and holds you there for a minute, grumbling to herself about how you're just making things worse
>Lightening up the pressure to something less than smothering, she continues a bit calmer this time, but still obviously frustrated, "Okay... new plan, squeeze in as close as you can", she orders, adding a "Just do it!" when she detects your hesitation
>Taking a deep breath, you dive under, wrapping your arms around her thighs and pressing your face in, letting her ass completely engulf your head and then some as you try to press yourself against her as tightly as possible

>You don't realize just how deep you've gotten until you feel her tensing, pinning you between her powerful glutes, and pressing your face up against the thin strip of cloth separating your face from her hole
>You feel more than hear her breath hitch, but the low cry that follows is audible, if muffled, still she manages to compose herself pretty quickly, and to your surprised actually manages to shimmy over a bit before you have to come up for air
>...about half an inch to be more precise
>"Well ....that's not going to work" she breathlessly informs you, taking note of just how long the hallway is, "But...keep doing that though, I'm almost there"
