Jennifer leaned forward awkwardly as her udder was impeding her movement and yelled at Susan "Transform or dare!".
As Susan turned round to Jennifer, Jennifer picked up her udder in her hands like a shotput and jumped onto Susan pining her down this time. She them dropped her udder onto Susan's face completely obscuring her mouth.
By the time Susan managed to claw it off Jennifer said "Times up, now you get both. Hmm what to do with you, I know I can get you back, shrink my udder and make sure you wont be going anywhere all at once".
A look of fear passed over Susan as Jennifer grinned at her.
"I dare you" she said "To drink from my udder until it is completely empty of milk. And I will transform you so that as soon as you ingest my milk you will gain weight. Lots of it, so much in fact that you will have extreme difficulty in walking."
"How do you like that?" She gloated.
