The last bump I give here, heres another writeup I did just to demonstrate the "theme" of what I'm going for:
<another hot scene: Imagine a new Corps member's first impregnation with Self Genesis.
She's a particularly weak willed younger one that kneels to the tentacles after simply SEEING some girls get fucked.
She snuck into the nest and beheld the breeding but instead of trying to save the girls she just started masturbating, getting herself caught. After birthing tentacles once and getting her power, Vital Bond, stolen she coos at the tentacles constantly. Begging them for sex and for them to grow her a futa cock.
>"Maaaaster. Pleeeease grow me a cock~ I want Kuon-chan and Ayase-chan to bear my cute tenty babies so bad~"
>"Master let me goooo~ I won't run~ I want to ride B-chan's cock~ *pouts* Pretty please?"
Tentaman has many powers and is very intelligent by this point. He is greatly amused by this new girl and decides to debut Self Genesis here after incorporating Vital Bond. He sets the whole swarm on new girl and fucks her wildly. As the tentacle fucking her cums the whole swarm melts into into semen, drives itself into her womb, compressing as into goes so her belly barely bulges, and combines all its power into a single sperm.
And new girl can SENSE this sperm's power.
>"Uooooooooh it's so maaaaaaanly~! The sheer masculinity in my pussy, oh god~ I can feel it swimming, I can sense it's power~ I-I'm cumming! I'm cumming from his very presence!"
She starts masturbating furiously, shivering intensely.
>"Yes yes yes yes. Please master impregnate my egg! Quite teeeeeasing me~ I want to birth you so fucking bad~"
She rubs herself against the girls. Tentaman the starts psychically sweet talking her:
>"Good girl, now go take in more of my semen from the others. I wish to do battle with their seed first."
The girls all grow cocks at his command. She rides them all and consumes their magical girl boosted tenta-semen. As she does this she senses him do battle with and consume the other spermatazoids.
>"OOOOOH it's a bloodbath in there! I can feel him conquering all the other sperm! He's so powerful, oh god I'm gonna come again~"
As she last orgasms on Kuon's cock he finally impregnates her egg, which then gives her a x3 orgasm. She then falls asleep in Kuon's arms, suckling her breast.
She spends the next day masturbating at the power in her belly. After waking up himself after a pleasant sleep, Tentaman uses Accel from inside her belly to rapidly advance the pregnancy, much to New girl's delight.
After she births him in his very long tentacle body he reveals his Ikemen form before her eyes. He then rewards her with some lovey dovey handhold sex.
After cumming a healthy amount of compressed cum into her womb he grows her a futa cock and invites her to DP the others with him, which she excitedly accepts.
He then wipes all their memories with Hypnosis and sends them all back to the Corps, unknowingly pregnant. Save his new Secretary whom he sends back as a spy.
