Those are the same ending.
If you lose your virginity to the dark goddess in the cultist encounter and then go to the Temple on the second map, the dark goddess will be there in the form of the hooded woman with the giant dick that pounds you on the altar... then it says something about you giving birth to the shadows and fulfilling your purpose, and you get the game over.
There isn't another scene with the demonic red version of the dark goddess that you see when you're trapped in the pig though, if that's what you're thinking.
From the script:
"CULTIST-TEMPLE-END": [
{
"sound": "CUM",
"text": "As soon as it touches down, your skin feels hot... your face looks anxious, but your heart feels full. You know you can never take back what's been done... and right now, you don't want to."},
{"text": "The dim light of the candles is gone, replaced by darkness. At first, you think they blew out as the ritual completed... but you no longer feel the cold marble on your hands and knees, or the thick cock in your bowels, or the smell of the wine and sweat..."},
{"text": "You feel as if you're in dark void, stretching out infinitely in all directions... and, with your heart sinking, you realize that's exactly where you are."},
{"text": "Rather than summoning the dark goddess to your world... you've been summoned into hers. And you don't have any idea how to leave."},
{"text": "She appears before you... no longer separated by a golden pig, you see her in her full splendor... and she smiles silently and darkly at you."},
{"text": "The dark goddess spreads your cheeks, and places her dark implement to your tiny human hole... and you feel yourself surrendering to her, mind, body, and soul."},
{"text": "The pain that you feel from being spread obscenely by her tremendous goddess cock is sublimated by a feeling of greater purpose... this was what you were meant to be..."},
{"text": "Her sex is brutal, deep, and unyielding... you feel more like a toy than a lover. Your body is limp, and your cock is ignored. You grab onto her and summon your strength... to declare your love for her."},
{"text": "\"Cum in me! Cum in me, goddess!\" you cry, and you mean it... you want nothing else but to feel her deific seed planting a tree deep in the pit of your stomach. You don't care that it will make you a slave to her cock forever."},
{
"sound": "CUM",
"sex": {"creampies":4, "other": "DARK_GODDESS"},
"text": "She fills you with it, unrelentingly, and you feel yourself drowning in her essence. A symbol of dark fertility appears spontaneously on your abdomen, where your womb would be... proof that you're her vessel, and you touch it in anticipation and awe, knowing that you're destined to be belly-bred and forced to birth her dark spawn."},
{"text": "..."},
{"text": ".."},
{"text": "."},
{"text": "Endlessly taking her demon cock into your ass and mouth quickly leaves you a hollow shell, unable to think of much of anything beyond your dark goddess' pulsing shaft and hot, demonic semen."},
{"text": "There, in that dark, forbidden realm, you prematurely ejaculate without shame, knowing that She has no use for pathetic mortal sperm. As soon as she penetrates you, it spits into the void, never to know warmth or light again."},
{
"sound": "CUM",
"text": "Again, she inseminates you, impregnates you... defiles you. You take it all, and give her back daughters by the hundreds... in the realm where day and night hold no meaning."},
{"text": "Repeatedly, she impregnates you, and your birth her shadow demons in the world beyond... an army of them sired by their dark mother - that is, you - for the sole purpose of spreading the dark goddess' terror to the world of man."},
{"text": "Birthing more shadows, you lay on your back, covered in sweat, the symbol on your abdomen glowing faintly... and from the darkness, you see emerge your goddesses' throbbing, dripping totem. You lick your lips in anticipation, knowing that it will bring with it a new litter of shadows... and a new litany of bottom orgasms."}

Even after having the cultist encounter be my character's only other sexual encounter, I am still unable to get this part of the script to be shown.
