"Too late Jen, you get both." Kyle said.
"Do your worst you fucking cock." Jen screamed down the phone.
"Ha ha, OK I will, first off, everyone know how much you enjoy cocks you, and your boyfriend are always bunking off school, and well the whole school know what you're up to, so for your transformation for every cum you receive directly into any of your holes, pussy, mouth or even your asshole, you will shrink the cock by the same volume until it becomes a clit like." Kyle explained.
"Ha ha, like that is ever going to happen!" Jen laughed.
"Oh it will, and to make it more fun, every cock you shrink off, you will grow the same size yourself! The only one way to get rid of your cock is to cum in others hole directly, and pass the cock grow on the one you cum with the same volume of the cum. Beware, every cock you touched can be easily cum much more, and recover fast.
As for your dare, you will first forget this conversation and also you will become more cock hungry than usual, and you will enjoy any sized cock even if it is only an inch long! and you will start enjoying fucking women and even men with your new cock. And people will willing to have sex with you." Kyle continued.
"Yeah yeah, like that's ever going to happen." Jen said.
Kyle hung up the phone laughing at his evil plan, meanwhile Jen set about getting ready for school, already getting wet from the idea of riding her boyfriends huge 14" monster cock after first lesson.
Jen picked her smallest skirt she could get and her cute panties.
After first lesson, Jen met her boyfriend Chris in the janitors closet.
Quickly they stripped off and Jen was really eager to get that monster 14" cock in her pussy, as soon as she had him hard, she dived her dripping wet pussy onto his cock.
Not knowing the chaos she was about to unleash.
She rode him like a wild beast, and after almost half an hour, Jen had stolen 2 inches from him, they both came three times rather than usual once, they quickly put their clothes on, and rushed to their next lessons.
Not noticing that Jen had now grown a 2 inch cock and that her boyfriend had now only lost a small amount of his large cock.
Jen ran off to drama her second lesson with her pussy and cock, now drooling for more.
