Kyle began to panic and thought fast. He then blurted it out.
"I pick dare!"
Jen cleared her throat... only for something unexpected to come out.
"I dare you to say transform or dare to me. I will pick transform and you'll make it so there's nothing left of my normal head but giant slimy tentacles like my body. Since I won't have a mouth, I want to have telepathic speech... also I want to feed off of sexual energy. Whenever I fuck someone with my tentacles I want to get full. Maybe have it taste... like pizza or something... maybe vanilla? Oh no, let each person have a different tasting energy! Oh also, I want to be bigger. Thicker tentacles and such." She said, content about her choice.
Kyle was speechless as he stared at her. Though his mouth was compelled to speak.
"T-Transform or dare!" He blurted out against his will.
"Transform." She said flatly
"F-For your transformation, you will only be tentacles... around a ball. Your tentacles will grow larger and thicker. Since you won't have a mouth, you'll feed off of sexual energy with each energy tasting... different." Kyle said, trying to think of some way to get back at her while he repeated... though once he finished, he added a bit of a curve ball.
"Also instead of your pristine pussy, you'll gain a giant disgusting and hairy cock with fat hirsute balls. Just really nasty and unlovable but you cum easily from it!" He said with a snicker as he watched Jen gasp... before her head was changing.
"You motherfucker!" He beard her shout in her head as her tentacles slowly swelled and grew longer. Her torso began to shrink with her head into a large sort of core to her tentacles. The large tentacle mass writhed uncomfortably until Kyle got a slight glimpse of her slimy pussy as it slowly pushed out. A ton of lose skin on the new growth as her clit pushed out into a cock. It grew and grew... reaching around 2-3 feet long flaccid. The core of the beast growing hairy despite all the slime. The rest of her pussy sealing as it pushed out into a huge swolen and hairy sack. The balls were too heavily engorged, instantly blue balled. Jen was freaking out. Not because she was a freak... but because she was now a he! Kyle took his chance and began to book it as Jen worried about his new cock.
