Oh yes it does

A soft giggle could be heard as Karen groaned in discomfort. How dare they laugh at her?! Was this there doing? Someone was gonna pay!

As Karen bent over to stand up, she became very aware of the unwanted house guest lodged between her ass cheeks. The pointy end angled towards her inner walls, making it much worse.

Blushing like crazy, as she walked awkwardly towards the bedroom door. What was even more bizarre was that her asshole seemed to be more sensitive than before. Every time she took a step the plug slightly moved, almost like a gentle feather was teasing her.

Karen swung open the door to the guilty faces of Mandy (sis) and Lara (mom). The laughter caught in there throats. A red face filled with anger but also a little arousal stared down at them.

“ what do you two think your doing? You woke me up and I’m not in the mood. Now i expect you both to get on with catering to my needs today. At least do that much for being such gossiping dorks. Can you understand? Or do you need it broken down?”

Mandy took the string of insults with some glee, eager to see the results of the spell in person. Lara on the other hand watched on with some concern, wondering about the spells limitations. Both knew what would happen next after this new act of misbehaviour.

“And another thing! Why are you both so…… so…… um….. I feel….”

Suddenly a pressure could be felt against her tight rear opening. Her eyes widened and she began squirm left and right, but it was too late. The spell was already enacting it’s punishment. The smooth metallic plug, began to grow once again, sliding deeper into her ass as it pulled apart her asshole.

“Something wrong Karen? You look a little uncomfortable?” Mandy said in a mocking tone

“Ffffffuuuuuck yooooouuu!” cried Karen. Pulling both of of her ass cheeks apart to lessen the pain as she grabbed them, she tried to wriggle away to the bathroom. Unfortunately the waves of intense pleasure and pain made it difficult to walk. Panting, Karen was left holding the wall for support, as she suppressed her whimpering.

“Karen please, if you keep swearing it’ll get worse….. don’t be such a pain in the ass like some kind of plu…. Er… I mean there’s still a way to reduce it….”

All Lara’s pleas fell on **** ears, as the helpless twitching and shuddering form of Karen finally made it to the bathroom door.

The plug finally began to stop growing, and the last thing they both saw of Karen was the outline of a round object barely emerging between the valley of Karens buttocks. Her shorts just about disguising her plight.

As the door closed Mandy was seen grinning ear to ear in satisfaction, loving how Karen’s face had twisted. What a perfect punishment for such a bitch. Maybe she could make it grow even bigger!

Lara looked at Mandy with disapproval; hopefully Karen could live with her new ‘friend’ with some grace. She was gonna be stuck with it for a long time.
