Bashed and swollen

Finding clothes to hide this…… thing had been difficult and had left Karen with little options. In the end she settled on a mid thigh skirt, rather than a pair of jeans that would cause bulging.

Making her way down to the kitchen for breakfast, Karen could only groan in annoyance at seeing her sister Mandy loitering. Eating a bowl of cereal, with a jug of milk sitting to the side.

“What are you still doing here? I’ve told you before I like my breakfasts alone?” Looking down her nose at her ‘lesser’ sister.

Rather than scurry away like she usually did Mandy surprised her by growing a spine.

“I don’t think I will Karen. I would behave if I were you, your gonna need help really soon” the mocking, teasing tone was not lost on Karen.

“Listen here you little brat! I’m in charge in this house. Certainly not you, so you better kiss my ass or else”

Karen glared at the sitting sister, who wasn’t bothered in the slightest by all the threats. Angry by the lack of response Karen she took a step forward to show her who was boss.

Which was when Karen slipped on a smooth piece of flooring, shaking the nearby table from the impact. Groaning as she lay on the floor, she opened her eyes just as the milk fell off the table.

Straight into the waiting crotch that happened to be underneath at the time.

Karen went cross eyed, as she felt her balls distort from the impact. She swore she could feel her nuts slam into the ground. Yet a large shudder of pleasure was accompanied with the pain. Her small cock grew hard and began to shoot out streaks of cum as though it was being **** out of her balls by ****. Tears ran down her cheeks as she held them in her hands. Already they were swelling in size, throbbing purple from the hit they just took. Feeling oddly empty.

A few minutes of crying and whining on the floor went by. Her skirt covered in white sticky sperm staining it. No one was around to ease her pain or clean her up.

Karen got up slowly, her stomach bunched up, her legs slightly apart and bent. Feeling the stickyness cling to her legs. Any anger or confidence she had was now erased, as Mandy stared at her with a smirk plastered on her face.

“That looked like it hurt hahaha, guess the spell was real….. “

Wincing Karen looked at her confused “spell? Magic isn’t real you idiot….”

Mandy rolled her eyes “suuuuure…. Look try and behave or those balls are gonna get totalled……. Or worse bigger”

Her eyes widened in understanding “My….. ooooh…..balls?….. so….. ow….you know about it?!”

Mandy just winked as she finished her breakfast and skipped past her bunched up sister.

She could do nothing to stop her walking past in her current state.

Damn it.

What did she mean by worse and bigger?
