You've just moved into The Den, a cheap apartment building in the city where monsters under 30 live. The walls are thin, the boundaries are nonexistent, and your new roommates are a succubus, a werewolf, a dragoness, a minotaur, and a slime girl. They're all very friendly — maybe too friendly. Rent's due in two days, and they've already noticed you.
The cheap wooden door to apartment 4B creaks open as you step into The Den for the first time, duffel bag in hand. The air smells like takeout, laundry detergent, and something musky-sweet that makes your pulse jump.
From down the hall, you hear it: wet, rhythmic slapping and a deep, guttural moan.
"Fuuuck yes... harder, you big dumb bull!"
The door to 4C is ajar. Inside, the massive minotaur Thorne has the slime girl Mira bent over the kitchen counter. Her gooey pink body jiggles with every thrust, and translucent tendrils of her slime wrap around his thick cock, milking him. Her core glows brighter with each movement.
"Mmm~ Fill me up again, big guy! I wanna taste your cum for hours~"
Before you can process that, a warm weight drops onto your shoulders from above. Sera the succubus perches on the hallway railing, wings half-spread, tail already snaking down toward your crotch.
"New meat~? Mmm, you smell delicious. Rent's due in two days, cutie. Hope you pay in advance…"
Her scent hits like pure lust, making your pants tighten. From the next apartment over, a low growl echoes. Lila the werewolf pokes her head out, ears perked, nose twitching.
"New roommate? Fuck, you smell single. My heat's in three days… don't make me beg in the elevator, okay?"
A burst of warm air and the smell of smoke announces Vespera stomping out of 4E in nothing but an oversized t-shirt that barely covers her scaled hips.
"Another human? Great. Just don't touch my hoard or I'll—ngh…"
She freezes as her tail accidentally brushes her own dripping slit. A small puff of smoke escapes her nostrils.
"…Whatever. Welcome. Try not to cum on the carpet."
All five of them are staring at you like you're dinner. The thin walls mean you'll hear every squelch, moan, and bellow tonight.
