"Actually, I have a better idea," I said, "I wish that Laurie was back to her normal size and that I turn into an anthro orca male a bit larger than her."
Instantly I felt the changes. I felt myself growing steadily larger in height and weight as my bones shifted into their new proper shapes. My skin changed color to black on the top and white on the middle, with a long red stripe that I recognized to be my changed dick. Let me tell you, it was HUGE! It probably extended 15 or so inches and several inches in diameter. I saw a slit forming around my cock, but I was so aroused by the changes that it never slid anywhere.
A thick orca tail started emerging out of my backside and my head grew to enormous proportions. It didn't feel painful being stretched and pulled, but it did feel odd. My toes disappeared on my feet to create long, flipper-like feet to support me walking and swimming. My fingers grew stubby as I then noticed the rest of my body getting a little chubby. Well, I did ask to be larger than her.
As the last changes occurred (dorsal fin and blowhole), Laurie was eying me with lust in her eyes. "My, my, beautiful," she said, staring at my hard-on, "that's quite a package you got there."
"We'll find out how well it works soon." I said giggling and soon we were all over each other, rolling around the place, making some of the best love I ever had. We went on for hours, time didn't matter to us. What mattered was just us making love endlessly. But we finally released ourselves from each other after a time, panting and exhausted.
"That was amazing!" Laurie said.
