Have the Slime absorb Preta

You have the Slime pin the Preta down.

"Absorb the Preta into your body." you say.

The Slime completely drains the Preta, absorbing his Magnetite. Once Preta was been absorbed, the Slime's body starts to change. It looks slightly more humanoid with arms and legs but no fingers or toes or ears or hair.

"Is there anyone I can absorb? I need Magnetite." she asks in a girl's voice.

"Where we get more magnetite? Do we have to fight more demons?" you ask.

"If you can have sex with me, I get Magnetite." she says. She slimes over to your dick. She undoes the zip. You get erect.

You feel her fingerless hands fondling over to your crotch, massaging it. She puts it inside her mouth and gives you a blowjob. After two pictures of them treatment you cum inside her mouth.

The Slime falls off you and begins to transform further.

It now human skin with short green hair and red eyes. It is a naked androgynous figure that is completely flat chested with no genital parts. It quickly covers itself.

"My boobs will become bigger and I will have a vagina if I absorb more Magnetite." it says.

You look round the corner to see a girl with long brown hair fighting more Pretas. You recognise her as Sarah Brighton from your class.

She blasts the Pretas with light.

"Hey you! Who are you and what are you doing here?" she shouts at you.

"Hey Sarah it's me Adam from school. What is happening here?" you shout at her.

"Don't worry, Adam, I will save you. Just try to stay away from these demons," she says.

A Preta sneaks behind you but the Slime smacks it away. You run over to fight Sarah is fighting the Pretas.

"Ah... I mean I seem to have gotten this Demon Summoning Program. I summoned this slime girl who helped kill one of them," you say, trying to catch your breath.

"Wait? You summoned a demon? There is a "program" that summons demons?" she asks you.

"Well I got my email from a guy named Steven who sent me this Demon Summoning Program. I thought it was a video game so I downloaded it to my phone. Then I found one of them Preta demons in this mall while getting my mother coffee and summoned this slime girl. She started off as a green blob but as she absorbed one of the demons and then my cum she changed into this form. She'll completely immune to their attacks." you explain.

While you and Sarah are talking a Preta tears Sarah's pants off.

The Slime girl grabs one Preta after another, absorbing them into her body. {law_hero} blasts more Pretas with light. The Preta rip off Sarah's jacket and shirt and bra. The brown haired girl has majestic tits that are now exposed to your view. Slime Girl is jealous. The amount of Magnetite she absorbed from the Pretas has barely given her any boobs and still no vagina.

Sarah still blasts away at the Pretas wearing only her panties and shoes. It looks like an erotic parody of Shin Devil Busters. Eventually the Pretas are all dead or absorbed into Slime Girl.

"I have to go home or my mom will worry, can we talk about this later?" you ask.

"Just be careful and try not to get attacked by demons," Sarah says.
