Cock

"I wish I could grow a large cock, at least 9 inches, but I wish it would disappear when I didn't need it." I say thinking of how what it would be like to have a cock to fuck my sister in law with.

"If that is your wish it shall be my pleasure." He plunges his hard cock back into me. Since I'm wet he feels free to fuck me really hard till I feel his hot magic semen in me.

"Wish Granted." He dissipates and I fall asleep next to my new lover. I wake, startled. There is a loud banging on the door. I stand up, stretch, and look around. My sister in law is gone. I feel sad about that but she had to go back to my brother and her family. I see a little note on the bed from her, promising to come back soon. I smile but it fades when I hear the pounding again. I go to the living room and open the door.
