Zoe's balls

"I wish that Zoe's testicles would each grow larger to the size of large plums and would be full of sperm and semen and when they are emptied they would only take 5 minutes to be full again."said Karyn.There was a slight glow from the wishing stone as it granted the wish,then Zoe felt a slight tingle go through her body and then centered in her testicles as they started to grow larger and larger the three of them watched in rapt facination as the scene before them played out. Zoe shivered as the overly erotic sensation of her balls swelling larger and filling up with sperm and semen it felt so good that she could start to feel the beginnning of an erection,she was so embarrassed to be having an erection with Karyn and her brother Jon watching that she tried to cover herself with her hands. "Stop that" said Karyn as she slapped Zoe's hands away from her groin."You're a bad girl Zoe for trying to cover yourself i want to see my handiwork in action." Jon upon seeing his sister getting a hard on felt compelled to either suck or fuck Zoe's large swelling erection as per a previous wish made by Karyn, when he tried to move closer to his sister and bend down to give her a blow job Karyn stopped him and said"What are you doing Jon i thought i told you to stand still"Jon replied "I was going to give Zoe a blow job like you wished for using the wishing stone remember?" "Well you just stand there next to your sister until i'm done with her ok."answered Karyn. Jon went and stood next to Zoe who had a slight look of both fear and arousal on her face,they watched her testicles continue to grow until they stopped growing then Zoe was compelled to say to Karyn "Thank you for my lovely large testicles Karyn." "Ah,yes they are nice and large aren't they" said Karyn as she moved forward toward Zoe then she reached out and cradled them both in her right hand feeling their great size and weight as well as the softness of the testicles. When she did this Zoe couldn't help but to feel how her testicles felt like to have someone to fondle them and they felt really good and it made her erection rise even higher and begin to show a little bit of precum start to collect at the head of her penis which made feel even more embarrased.All she could think about was how really good it felt and how embarrased she was and if she could some how get Jon to give her a blow job like he seemed to have wanted to do earlier because the way Karyn was kneading her balls with her right hand was making her hornier the more she fondled them. She didn't really love Jon like the way Karyn had made Jon love her,in fact she was a little revolted by the fact that Karyn had them perform two sexual acts so far but she was so horney that she didn't care right, now all she cared for was to put her 15" cock in Jon's mouth or his still slippery pussy. "Hmmm" Karyn said with look of dissatisfaction on her face."No i don't like hairy balls at all,they're just gross." so she held up the wishing stone and said "I wish that Zoe didn't have male pubic hair but instead had female pubic hair instead." The wishing stone glowed slightly and the power from it began to rearrange Zoe's pubic hair in a blur and when it was done they all could see Zoe's long erected penis and her large balls surrounded by dirty blonde female pubic hair."Thank you for my beautiful female pubic hair."said Zoe. "You are quite welcome my darling Zoe" said Karyn with a look of satisfaction on her smiling face."Now Jon." She said while turning her head to look at him "What shall i do to improve you." She stood there thinking for a minute looking him up and down before saying "Ah yes i know what i'll wish for first" said Karyn "I Wish...".
