Rachel watched the young boy with the face of her friend roll over onto her... his?... back, and call out to her, "Rachel, something... I can feel it happening... again..."
The voice was close to what Cassie's sounded like, but different, explaining why it sounded like Cassie had a cold or something over the phone. Rachel's eyes widened in shock and awe at the sight before her, as the boy let out a long, loud moan, back arching slightly as Cassie began to get an erection. Rachel couldn't look away, watching as the boy's little penis began to grow, throbbing with each moan, thickening and lengthening, and just when she thought it might stop, it just kept growing.
She had seen a lot of dicks on the internet, and knew that this one was quickly reaching porn star levels of size. When she thought that it might just get too big and pop like a balloon, it finally stopped, throbbing and partially blocking her view of her friend's red, horny face.
Rachel nervously took another step closer, to get a better look at Cassie's now boyish face, "Cassie? Are... are you alright there? You're looking a little... worked up?"
Still panting, a few, little moans slipping from their lips, Cassie blinked, "Ya think? This thing keeps getting bigger... each time I... I... I get horny..." Cassie looked on the verge of tears, even though still looking very much horny, "It started out so small... and manageable... but now... I've orgasmed five times... or was it seven... I can't remember, but anyway... now it's... it's... it's the size of my arms now... I'm a little boy with a huge... throbbing cock!"
Rachel looked at her regressed and gender-bent friend, and the giant, throbbing cock that was demanding everyone's attention, finding it hard to think or look her friend in the eyes. She swallowed and held up a hand, trying to block the cock from her vision so she could actually concentrate and communicate, "Cassie, how did this happen? This doesn't make sense... you can't just... turn into a huge cocked shota out of the blue!"
"I... I got a call, there was no caller id... I didn't even think and I answered it... I didn't get a name or anything, just someone asking me something... I don't remember... then when I didn't answer them, they just laughed and said that I'd now become a young, horny boy whose cock would grow and grow until someone else takes care of it for me... I hung up thinking it was some kind of weird prank, but then... then... this started happening..."
"Holy shit... that's... I'm seeing this and I still don't believe it! Wait... did you say, someone else has to take care of it for you? You don't mean... me?!" Rachel stepped back and dropped her hand, her eyes locking onto the huge porn star cock jutting up from her friend's crotch once more.
"Please Rachel... please, I... it can't grow any bigger... please help me! I've already ruined the clothes I was wearing..." Cassie begged, pointing over to a pile of soaked clothes in the corner of the room, a cute pair of panties lay shredded on the top.
