Super Cum

With your cock lodge deep in your sister's throat, your mind wanders back to when you first entered this place. There was something you remember about a horse. Something about concentrating on your fantasies or something. Anyway, you can't quite remember exactly, but all you can think about is how much you want to cum all over Rachel and Amy. All over them. You think hard about cumming gallons and gallons of jizz. You want to plaster them from head to toe in your cum. As you concentrate, which is quite a task for you given the situation, you can feel your balls actually start to expand. Your normal sized balls slowly grow to the size of tennis balls, then to the size of small grapefruits!

You pull yourself out of Rachel's throat and look down at your low hanging, hairy balls. They're enormous and ready to burst!

"Well, this should be fun!"

Rachel notices your huge nuts, "Oh shit, that can't be good."

You step back up and fuck into Amy's mouth one last time. Your balls completely cover her nose and eyes now. You push into her throat one last time and grind yourself into her face. Then you swap to Rachel, working the last bit of yourself to orgasm in your little sister's throat.

"Fuck yeah, here it comes girls!"

Your first blast goes right down Rachel's throat and she is **** to swallow most of it. Then you pull back and fire one into her mouth, instantly overflowing it. You pull out of her mouth and fire two blasts into her face, covering her in your spunk. Then you quickly push your cock back towards Amy. You fire two huge blasts into her mouth. She tries to swallow, but it is way too much for her. With your cock still shooting our jizz like a cannon, you cover Amy's face with three more blasts. You aim your cock back and forth at their faces, firing rope after rope of thick cum all over them. You are still firing as each of their faces becomes completely covered in cum, dripping down onto the floor. You tilt your cock up and fire even more blasts onto their tits. Your cock continues to machine gun fire spunk for the next minute, soaking both of their tits, necks, faces, and Rachel's bed and the floor beneath with a thick coating of sperm.

"Holy fucking shit!"

Both girls are **** on your cum, trying to spit or swallow it so they can properly breath. It's in their mouths, on their breasts, up their nose, covering their eyes, in their hair. There is literally jizz everywhere. It looks like the ending of a 50 man bukkake film and it all came from just your balls - which, luckily, have shrunk down to their original size.

"Haha, that was fucking awesome."

You take a few steps back to admire your work. Rachel and Amy slowly roll off the bed and onto the floor, trying to compose themselves and wiping your cum from their glazed faces and bodies.

"Holy hell, David, that was like 4 gallons of fucking cum!" Rachel screams, "You fucking destroyed my bed! Look at this shit, there's no way I can clean this shit up!"

You laugh to yourself, "Well, not my problem, but thanks for the blowjobs."

Amy wipes enough cum from her face to finally open her eyes and looks at you. "That was incredible! You can do that to me again anytime you want!"

You smile back at her. "Oh, I plan on it." You dick softens and you slowly back out of Rachel's room thoroughly satisfied. That was a nice diversion, and you learned that if you think about something hard enough, it comes true. Interesting, you think. "I will definitely need to use that more often." You make your way back down the hallway to the living room and plop down on the couch, planning your next adventure in blowjob universe.
