Jen looked over at Mary, knowing who her next target would be.
"Hey Mary, would you come to the bathroom with me?" Jen asked, and Mary nodded. It wasn't unusual for them to go to the bathroom together, have a little girl time before classes started up. As they walked, Jen tried to think up something good, roaches were hers...what would she bless Mary with? Ants? Wasps? No, no...those thighs are so juicy and thick, she can hold something much larger. Why stop at bugs? The school has plenty of mice...perhaps they would like to nest inside of Mary.

They reached the bathroom and Jen turned to look at Mary. Yes, that thick ass and thighs, and the slight pudge would look great paired with a large, rounded belly filled with mice.
"Mary...transform or dare?" Jen said, but immediately went to cover her mouth. She had plans, beautiful plans. Mary struggled, especially when she saw a roach crawl out of my mouth and down my chest. "Now you get both!" I said gleefully. "Now, you will transform into something just like me, except instead of roaches...all the mice in the nearest mile will crawl up that juicy pussy of yours and nest in your uterus. They'll continue to mate in there, making you bigger and bigger. Your dare, hmm...I dare you to spread this curse around, and treat me like your queen. I made you, I can change you however I want, whenever I want. If I want to be changed, you will transform or dare me and say whatever I tell you."

She looked like she was pregnant with quintuplets by the time they were all in there.
Mary opened her mouth and said...
