Melanie can be teased

June smiled coquettishly at her sister, her eyes wandering up and down the street as she wrapped her arms around Melanie's neck.

"Today's going to be a really fun day little sis" she whispered kissing her ear and playfully pressing her breasts against the other girl's back.

Melanie blushed and crossed her arms. As far as she was concerned this was normal behaviour.

"June can you..." She remarked starting the sentence before the wild magic of June's snap affected her.

"Can I what?" Asked the wannabe godling, momentarily unaware of what was about to happen. Her deep in wild fantasies had assumed that Melanie was an innocent.

She was wrong.

In a moment Melanie had turned around grasping her older sister's body and pressing her into a deep and passionate kiss. June felt her eyes fly open, blushing as she realised her mistake. She made Melanie attracted to her when she was still John that meant that Melanie was just as susceptible to her magic.

She moaned into Melanie's mouth feeling the younger girl slipped her hand between June's legs with a sudden eagerness. She hadn't expected this, but now she could think of little else. The sisters groaned rubbing against one another Melanie becoming more and more possessed by her new perverse desires.

The power of the snap was just as effective on Melanie as it was on any boy. And that meant that she was going to impregnate her older sister.

June gasped as she felt something new her sister was growing larger and more feral with every moment. Her eyes going wide as she realised that Melanie was going to need a change in hardware in order to impregnate her.

She struggled trying to snap her fingers, but it was already too late. She felt something large rubbing against her crotch and looked down just in time to see Melanie's skirt tent under the rising equine erection.

The wild magic was already affecting her, she'd already warped her own desires so she was all too happy to let her sister burst from her clothing. She felt the flared head of her sisters titanic horse cock pushing against her lower folds. She gasped wrapping her legs around Melanie's waist being pulled into the sudden insanity of the transformation.

Melanie was sniffing the air, her face was stretching out and her nostrils growing larger. With every move the changes were becoming more pronounced. It was alarming but Melanie was already to arouse to stop. She wrapped her fingers between her sister's. She was Groaning and gasping as she began to thrust. Back and forth up and down, right there in the middle of the street she pinned her sister to the ground. They kept on going. Pumping back and forth, both losing themselves in the complete depravity of their pairing. It was quick it was dirty and with a sudden cry of absolute ecstasy Melanie pushed herself as deep as she could spraying her new seed as her ovaries dropped from her vagina transforming into testes just in time to fertilise June.

June lay there panting, her legs spread wide as her new anthro shemale sister finally pulled out of her.

"This was not how I planned it," gasped June
