"I always wanted a horse cock" Jennifer admitted as she heard her options listed "they where always so massive and I loved how big they where."
Kyle smiles and says "Oh so you like big horse cocks then I'll give you a massive one! You will grow a huge 6ft soft horse cock that gets erect and grows another foot every time your name is said. But you will grow this cock from your mouth not your crotch. Have fun!" and he hung up the phone.
Jennifer turned to look at herself in the mirror as she felt her tongue start to thicken in her mouth then watched in fascinated horror as a horse cock pushed out of her mouth and grew and grew and grew. It eventually rested on the floor as it was longer than she was tall and it was soft! She dreaded going to school and even touching her new massive edition but almost couldn't resist as this was what she wanted if anything she wanted more cock just not from her mouth!
"Jennifer you need to get up and get ready for school sweetie" Her mom called up the stairs. Jen looked in horror as her cock started to fill up getting longer and hard as her name was called. It suck strait out of her face and reached 14ft in front of her then it jerked and grew to 15ft. Her breasts also swelled reaching F cups as they swelled with cum and she couldn't help but start to jerk her cock in hopes she could cum quickly and go soft so she could get ready for school. Just as she started to stroke her massive cock her younger sister burst into her room the 9 year old brat had so sense of privacy worse she came called Jen's name. "Hey Jen do you...? What the fuck is that Jen!" Jennifer groaned as her cock surged at each mention of her name reaching 17ft and drooling pre. Jen looked at her sister and dove for her ripping her pants off and shoving her huge cock into her little sis even as it grew more and her sister screamed "Get of me Jen! Get away! Don't shove that thing into me Jen! JEEEEEN!" She screamed as the massive cock bulged her stomach and traveled deep into her. Jen watched as she grew another three feet reaching 20ft and was confused as she saw the bulge from her cock enter her sister's throat. Her cock had connected her sister's pussy to her throat so she could fuck her sister all the way through since she was so long. Jen shoved more of her cock into her sister's pussy and was highly aroused to see 5ft of cock push out of her little sis's mouth. She fucked her in earnest and came shortly afterward bathing herself her sis and her room in gallon after gallon of cum cumming for several minutes before she finally finished. As her cock softened she looked at Mary and and remembered how hot she looked with over 12ft of cock coming out of her mouth and asked "Mary transform or dare?"
