At first, Jen was completely baffled by what she just heard, but then she felt as of she had lost all strength in her body and slumped downwards until her face was only about a foot off of the ground. She was stuck starting down at her massive boobs, unable to move too much outside of a small wiggle. Her massive boobs lay completely on the ground as well. Her face was stuck tilted fully back too, which normally would have been very uncomfortable, but now felt like its natural position.
Her balls then started to "walk" without her direction, confirming for her that everything Kyle just said was both the truth, and her new reality. Jen was now just the human shaped cock of her cock. As her cock walked around, her boobs rubbed against the grass and started turning her on. When this happened, Jen felt herself raise up, as her back straightened out, until she was facing forwards. Her jaw was also stuck open, with her lips creating a narrow, oval shaped, vertical opening that resembled her pussy exactly. She couldn't open or close them anymore, but still could manage to speak through them somehow. She looked around and saw others in identical situations as herself. Several massive cocks were moving around, some carrying purses, others wearing shirts, and all of them had girls either bent over or pointing forwards depending on their various states of arousal.
She then saw Beth still down by the river, her face was actually underneath the cum's surface, almost like she was drinking or eating. Then Jen noticed how her breasts were blue colored and her cock body quickly walked over to Beth. Her Cock tapped Beth's cock on her shoulders and the next thing Jen knows is that she is being slowly inserted into Beth's mouth. To both of their surprises, Jen slowly begins sliding inside of Beth, causing Beth's mouth and Jaw to widen in order to make enough room for Jen's head and torso.
Jen was pushed deeper and deeper into Beth, and no longer could see anything besides darkness. Oddly enough though, she was feeling amazing. Every inch of her torso and head tingles in tiny burst of pleasure with each and every movement, down to the smallest twitch. Jen was quickly getting lost in the world of pleasure, as she was now starting to be pushed and pulled in and out of Beth's throat, as her Cock began using her to fuck Beth's Cock.
Jen's mind was quickly shifting from thoughts of how to undo this all, towards direct requests to her Cock to go faster, and some instructions on how to better use her human cock self to pleasure Beth's human cock self and her Cock body. It wasn't long after that that Jen suddenly felt the urge to vomit and puked out a huge cum load into Beth, and then did so about 5 more times, each right after the the other, as she pumped Beth's balls full of cum. Jen felt like she would go insane from the pleasure she was feeling, but never quite managed to cross that line.
Jen was then pulled out of Beth's pussy mouth and flopped down onto her boobswhich once again were resting on the ground due to their size. She was feeling the pleasant afterglow of having the most intense orgasm she has ever experienced in her life, when she began to lift up once again. Just in time to watch Beth vomit out all of the cum Jen just pumped her balls full with. Her own Cock began stroking her right side, making Jen shiver in pleasure as she felt her former hands start to use her to masturbate. After a few minutes, Jen yet again vomits another wonderful fountain of cum directly into the river. "Oh my god being my Cock's cock feels so good!" She exclaims, falling flaccid again, but only for just a few moments. This reality still has everyone forced to have permanent errections afterall. Meaning that Jen, as well as every other woman in existence, are all now said errections.
Jen would definitly try and figure out how to fix all this, but just maybe after testing out the new waters a bit more. It isn't everyday that she gets to be the cock of a giant cock after all, well, until now at least.
