"Will you now? Then I may just have to take you up on that. However I have another idea. You will still be my fuck bunny girlfriend of course, but I will add some of my own personal flair to our relationship using that program" says Steph as she picks Lily up and carries her over to the Chronivac. Then she sits down with Lily still riding her cock and goes to work.
Since her back is to the screen, Lily has no idea what Steph is doing either, but she doesn't care anymore. Steph can have it for all she cares. She has gotten her wish and is now looking forward to enjoying living as a fuck bunny for her girlfriend's pleasure.
After several minutes of fucking while typing, Steph stands up and returns to the bed where she lays Lily back down, this time on her stomach though. Steph then begins renewing the frequency of her thrusts as she waits for the changes to begin.
It starts with Lily, who while being fucked doggy style, feels her clit begin to itch and throb. Then with each thrust, it pushes out from her a little bit. She realizes what is happening almost immediately too. "Am I also growing a cock?"
"Why of course you are, however your cock is special. When it gets erect, it bends backwards between your legs." The moment Steph says this, Lily's cock twitches and indeed bends down between her thighs and continues to curl backwards. It keeps going, growing longer amd longer still until it touches something wet. Then enters into it, as lily's black colored cock begins burying itself into Steph's pussy.
"Oh yeah! That's the spot! And I love how your cock kept the color of your uniform too!" Moans Steph as she fedls Lily's cock sliding deeper and deeper into her pussy with every thrust. Now that they both were fucking each other, their pleasure doubled instantly.
Lily could feel her tits flopping wildly beneath her, even though some of their shape was a bit ridgid thanks to the shape of her body acting like a real corset. With each and every thrust, a small bead of milk began to drip out of her nipples. The rate slowly begins increasing until in about a minute, she already is spraying milk out of her nipples as if she has sprung a leak. She is so full that the slightest movement causes her milk to come out. Her cock finally stopped growing, now deeply buried into Steph's pussy. But unlike Steph, she did not grow a pair of testicles, nor is her cock able to actually cum. It basically is a pseudo-penis, in other words, her clitoris is just shaped differently now.
The next change is to Steph. Her nipples begin widening out horizontally, and split into a pair of folds, becoming inverted. However it doesn't just stop there as a tongue quickly grows out of each of them, as the folds finish becoming mouths. No teeth, but fully able to speak, the number of moans doubles as both boob mouths start moaning as well.
Steph flips Lily back over onto her backside once more. Lily's clit-dick luckily is long enough to wrap around Steph's cock so even though they changed positions. Steph then leans down and her new nipple mouths suck up Lily's nipples into them, swallowing her milk as quick as they can.
With every swallow, Steph's own breasts slowly begin to swell, taking all the milk and turning it into more, temporary breast tissue. A feature she came up with so that she couldn't excessively flood her tits and be stuck with them oversized forever. They will always shrink back down to normal size in about 24 hours too.
However at this moment, Lily is being buried underneath Steph's swelling tit flesh as her endless amount of milk is continuously being swallowed.
"So Lily, how's this for sex?" Asks Steph to fuck bunny being pinned to the bed underneath her enormous and still swelling breasts. "So good!" Is all Lily can say. "I agree, this feels incredible. I'm looking forward to changing the world with my adorable fuck bunny and her interesting program."
