A body popping orgasm

"Oh you will be getting that multiple orgasm any second." You say with a grin. Not wanting your step sister to become pregnant from either Justin or you, you use your new power to turn both of your cum into popcorn kernels that pop at body temperature. Her body now secrets butter from her mouth, pussy, ass, and breasts.

As each kernel pops it gives her a mini orgasm. Each by themselves would not be noticed but with millions of kernels Gwen is soon ridding an orgasm wave she won't soon forget. She gasps and moans with delight as the number of popcorn popping increases. Soon her moans are muffled by all the popcorn popping out of her mouth. Her hips buck and quiver as even more popcorn pops out of her pussy.

Justin reaches down and eats some of the popcorn from her pussy.

"Hmmm. Well buttered I hope we can do this again soon." Justin says stuffing his mouth with one hand and jerking off with the other.

"I don't think she will be in any condition to have sex with us again tonight. After all it will take her that long to pop out all that cum. Though I don't think she will want to miss the next melted butter movie night. After all its the only night she can have sex and know she won't get pregnant and have the most orgasms she will ever have in her life." You say as you pick up some popcorn from her mouth and dip it on her dripping nipples before popping it into your mouth.

"Besides we will never be short on popcorn again. So want to watch Gwen, the movie or see what other fun we can have?" Justin asks as her cums on Gwen's stomach. The two of you watch as his cum turns into popcorn right before your eyes.
