Split the difference

It felt a little different sliding your way into Zoe's slick channel this time. Entire body seemed to squeak as you slip between her thighs. It's not quite the same, it feels a lot more raw but it also brings home just how much the magic ray gun has changed your sister. When she's like this she isn't really your sister she is just the thing that you use for your own amusement.

You grip her squeaky breasts pounding her harder

Imagining what kind of sensation it must feel to have the life breath literally fucked out of you.

After what feels like an eternity you finally feel the tell-tale twitch spraying more seed into her plastic womb before pulling out the gun and shooting her back to her old self.

Or at least you thought she'd be her old self did you really have all the dials set the right way?
