She wants to do it again

Zoe lets out another loud sigh of relief. You see her hands go back to her cock and start stroking it yet again.

"That was so good... I have to do it again." Your sister got this dopey look on her face.

"Idiot." You say while cleaning some cum off your lips. "You can't get hard again that fast. I did what you told me to, now change me back." You hate how bratty your voice sounds. It's like having to hear a Justin Bieber fan everytime you spoke up.

Zoe gives a dissatisfied look at your statement. She then seems to remember the gun she is holding and a deviant smile creeps up on her face.

"Can't I?"
