The next day Jessie arrived with a girl a little younger than her. The girl came to us looked all over our conjoined body.
"It's just like you said big sister, this is amazing." the girl said
"She is Erika, Jessie's younger sister." Sarah said
"Sorry about that. She caught me jacking off last night and made me tell her how I got this dick. Today she insisted to come along with me." Jessie said
"Of course I had to come, I couldn't let you have the fun just for you." Erika said
"I mean you want to be transformed somehow, don't you?" I asked
"That's right, and I've already decided what I want." Erika said
"So just say that we will make the necessary wishes." Sarah said
"First I want you to make me a hermaphrodite just like my sister." Erika said
Sarah and I liked the idea and said at the same time "We wish Erika to be hermaphrodite just like her sister." Quickly a large bulge formed in Erika's pants, which opened the zipper leaving her new member exposed. Jessie sure was excited about it, as she was stroking her hard cock through her clothes.
Erika, seeing her sister playing with her own cock said "I see you're liking big sister, but we're not done yet."
"You want more?" Jessie asked
"Exactly." Erika answered her sister and then told us "I want to be conjoined with my sister just like you two."
"Jessie, what do you think about that?" I asked
"I liked it, you can make the wish." Jessie said
So Sarah and I said "We wish Jessie and Erika were conjoined just like us." Soon their clothes disappeared and they were forced to stand side by side, and ended up like Sarah and me, with Jessie on the left and Erika on the right.
Once joined, the sisters led us to Sarah's room and placed us face down on her bed. Then they penetrated our anus with their hard dicks. I could feel both asses being fucked by the conjoined sisters, the two different since only one had a prostate, until they came inside our asses.
After the orgasm, the sisters centered beside us with their sticks still hard. They took their balls out of the way, offering their pussies and saying "Now it is your turn."
Understanding what they wanted I said "I wish Sarah has a dick and balls." and Sarah said "I wish I had a dick and balls." Sarah's new cock has already grown hard and so we started fucking Jessie and Erika's pussies.
With each thrust we gave the sisters hard cocks hit their bellies, but they were loving it. Quickly Sarah and I came inside of them, which also came, and their cum flew right into their faces.
