Baptismal pool of cum

Walking through the door Supergirl looks around curiously, they are in a cavernous room of dark stone with the center piece a large baptismal pool filled to the brim with an off-white viscous liquid.
'Oh Rao, the smell... that's... that's all cum... and the pipe it's still dribbling from goes up there and... yeah, of course it is connected to the pipe I saw going from the door and into the club... shoot, does that mean the XXX shots I had was sperm?'

"Impressive isn't it? I don't pretend to understand the magic, but these rooms are in an in-between realm, between National City where we came from and the outskirts of hell. The pool is filled from many rather fucked up rivers going through hell... which is straight through there" One of the cultists waves towards where the pipe vanishes through a doorway with a red glow coming through it.

"Now, for the final stage of the initiation, please follow me" She does something to the robe, and it drops to the floor before she steps naked down into the pool.

The other cultists have moved into two lines along the pool, all of them removing their robes and all as naked underneath.
While they have many different body types and amounts of body hair, they all seem to have flawless skin except for a circular tattoo of some arcane symbol on their pubis right above their genitals.

'The heck... I could've sworn they were all women, but half of them have penises... like... really nice sized dicks... I've got a really bad feeling about this, but I'm not sure if I could get back through the door if I tried to run away... and I've come this far, I'll just put a stop to it if they go too far'

Trying to ignore the weird tingling from her lips (both upper and nether) as she looks at the naked women, Supergirl removes her stolen robe and starts walking toward the pool.

"Not that I have anything against toasters, but I'm pretty sure your instructions earlier today was to wear nothing at all under the robe." The leader down in the pool looks up at her with a slightly exasperated look, bordering on a frown.

"Oh sorry, I... yeah, sorry I'm no good at reading instructions" Supergirl chuckles awkwardly before she starts to pull down her boxers, trying to ignore the string of wetness momentarily stretching between the boxers and her pussy as she pushes them down.
'Ok, I'm about to go skinny dipping in a cum-pool, my life is so weird. Damn it must be cold in here, it's got my nipples hardening up like crazy' she almost manages to convince herself, only ruined by the fact that the room is hot as, well, hell.

Taking a deep breath Supergirl walks down the steps into the pool and over to the naked leader already standing there.
'Oh man, how can it all still be body temperature, well, human body temperature anyway, not quite mine... eww, it's like walking through jelly or slime... or I guess cum.'

The leader puts one hand behind her back and pushes Kara's shoulder gently with the other until she's got her floating and being held up by the leaders arm.
Three other cultists step into the pool with small bowls filled with yet more cum.

Grabbing one of the bowls and looking down at her, the leader taps the bowl against Supergirl's lips, and as she opens her mouth feeds her half of the bowls content.
She then waits until she sees Supergirl swallowing it all before emptying the rest over her half submerged head "With the seeds of Onan, you will incite sexual thoughts in all who see you"

She then takes the second bowl and repeats the feeding and baptism, again waiting until she sees the initiate swallowing "With the seeds of Narcissus, you will think of yourself in sexual ways"

Taking the final bowl, the leader reverently feeds Supergirl the sperms smiling as she watches them be swallowed, she then empties the rest over Supergirl's head "With the seeds of the succubus Blaze, you will act out her will!"

"Now partake in the seed from the river of legion, open yourself to Blaze and be reborn!" while the baptism had been ongoing, the rest of the cultists had entered the pool, surrounding their leader and the super-initiate, at the leaders command they all reach cum-slick hands out and start running them over Supergirl's body, caressing and covering her before starting to push her under.

'This is so messed up, do they want me to drink this whole pool, or do I need to drown to be reborn? Oh sweet Rao, do they have no shame, they are touching me everywhere... ooh hands... hands in new places! I guess they were literal about opening up for Blaze'

While Supergirl doesn't need to breath as much as a human, the myriad hands caressing and masturbating her have their effect.
Cum fills her up as one cultist's fingers invade her ass and another fingers her cunt, letting the pool fill her every crevice.
As the feelings start to get too much a gasp leads her to swallow large amounts down her windpipe.

'They are... they are trying to drown me, and make me cum and Rao it feels divine... wait how am I still breathing?
I'm so fucking horny... I want to cum, I want cum... I want!
This tastes so good... I... I need more...
Oh Blaze I'm cumming!'

As she cums the last of her air escapes her body.
Seeing the red glow near their initiates pubis the cultists lift the still shuddering Supergirl out of the pool.

"Congratulations, you are now marked as a Disciple of Blaze, your initiation is finished" so saying, the leader gently lays her hand on the brand tattooed onto Kara's pubis.
