Jenny looked to her side of the bed and found Sam still sleeping. She also had a morning wood. The horse cocked girl decided, driven by lust and the emptiness of the act in her dream that was interrupted when she woke up, to use the still sleeping girl to relieve herself.
Jenny moved Sam carefully so as not to wake her, making her lie down with her hard cock pointing up. She then stood on top of the girl and bent down, sitting on her cock and pressing have her pussy penetrated. She then goes up and down the member to ensure her sex with the sleeping futa.
After a few minutes Sam had some spasms, moaned and came. Jenny came too, shooting her the fuck away.
Sam ended up waking up during her orgasm, but he couldn't do anything while he came. When her orgasm was over she looked at Jenny sitting on top of her recovering from her own orgasm and said "What did you do?"
"I just woke up and saw that we both had a morning wood so I decided to make a little surprise for you." Jenny said
"Oh no, you screwed up. You shouldn't have done this." Sam said
"Why not?" Jenny asked
"It's because... I should have told you before, but since you hadn't asked me to fuck your vagina I ended up forgetting. Turns out I have Itch too." Sam said
"No problem, I also have Itch so I don't think anything will happen to me." Jenny said
"I'm not so sure. When I found out I had Itch, I researched about cases of relationship between futas who had the condition, but I only found relationships between those in which all had already transformed someone on their horse cocks, and no relationship between those who that hadn't or that only one had done it to confirm if they could have any immunity." Sam said
"You're not serious are you? I will not become..." Jenny said and tried to get off Sam, but it was too late and her new friend's cock had already fused with her pussy. "Now I screwed up. I've already started to become your dick." she said. She felt her legs go numb and soon after they merged into a misshapen mass that became a ballsack as she, who was facing Sam, was forcibly turned to face her back.
"I'm sorry I should have told you before." Sam said
"Do not blame yourself. If anyone is responsible for this, I'm the one who advanced on you while you were sleeping without thinking about the possibility that you had Itch." Jenny said
From this point on, the transformation took an unexpected turn, moving towards a result that neither of them had seen during their research. Just above Jenny's ballshack changed legs was another ballsack, which was her horse's cock, which was still intact, and even with the progression of the transformation it didn't change at all. Her arms were absorbed by her sides, her breasts were also fully absorbed, her face slowly disappeared along with her bones that dissolved, making her a shapeless pillar of flesh. Her skin split open at the tip and retracted all the way, leaving her new horse cock form exposed, forming her new sheath and officially making her Sam's cock.
"What do I do now? I didn't want Jenny to be my dick. But what is this? Why do I have two dicks?" Sam said wondering about the strangeness of the final result of the transformation. She now had two horse cocks between her legs, one three feet long, which was Jenny, and the other two feet long below, which was the dick Janet had become. Farther down were two ballsacks one in front of the other, the one behind, which Jenny's legs had become, was bigger than the ones in front.
Sam then took the dick that was Jenny and felt it, feeling its entire length. It was a lot more sensitive than her old dick. Then she repeated the process with the other dick, but she didn't feel anything, as if it wasn't part of her body.
"But, why can't I feel anything on this cock? It's between my legs and yet I can't feel it." Sam said as she continued groping her smaller cock until she heard a moan in a familiar voice.
"Mmmmm... Yes, it's going really well, keep it up." said the voice that clearly belonged to Jenny
"Jenny? Are you there? Are you still alive and aware?" Sam asked, totally surprised
"I am. I also thought it would be the end for me when I became your dick, but for some reason I still have my conscience intact. I can see and hear through your eyes and ears and, well, I can't even explain how I'm managing to speak." Jenny said
"That's weird. And you said it feels very good as I touch it, but I don't feel anything." Sam said
"But I feel. Strange, it seems that even though I am your dick now, I still have my own dick." Jenny said
