Several hours later, Penny looked at me with a broad grin on her face.
“What a monster,” she said, licking her lips suggestively. “Wait here,” she told me, crawling out of bed, “I’ll be back in a minute.”
Sitting up on the edge of the bed, I waited for Penny to finish going to the bathroom, examining my enlarged cock in amazement. While I was waiting, I tried pulling the ring off again, though to no more effect than the first time. It was like the damn thing was superglued to my finger or something.
Just then I became aware of my body suddenly changing again. Penny, I thought to myself. I could feel it in my whole body. It was like I was stretching, and when I looked at my arms, I could see my muscles getting bigger yet again. I could feel them swelling larger and larger, and me getting stronger and stronger. In just moments it had stopped and I started examining my body in amazement. I was huge.
Then I heard Penny’s voice asking, “Ready for some more lover boy?”
I looked up and saw her standing at the door to her bedroom, a broad grin on her face and the necklace in her hand.
“You’d better believe it,” I said grinning back. Within seconds she’d dropped the necklace and jumped at me in bed, eager for more action.

The next morning we used the necklace to change me back to normal size. Or at least my muscles. It would have attracted a little too much attention for me to have suddenly gained 50 lbs of muscles overnight, so they had to go. The other change however I wanted to keep.
“The damn thing still won’t budge,” I complained to Penny as I struggled uselessly with the ring.
“Maybe this will help,” she suggested, going to her kitchen and coming back with her dish soap.
After trying that, and just about everything else we could think of to loosen it, I finally had to give up or I’d miss my class.
“We can try again later,” Penny suggested hopefully, looking a little disappointed.
I guessed that she still wanted to try it herself. Knowing that I’d have to stop by my dorm room for my books before class, I told Penny goodbye and that I’d see her later. She just grinned back mischievously and I suddenly noticed that she had the necklace in her hand. As soon as I felt the shifting sensation in my groin, I quickly pulled down my pants, wincing as I saw my cock. It was no longer the 10 inch monster it had been, but was instead only an inch long.
“I look like a fuckin kid!” I exclaimed, obviously not very happy about this.
Penny giggled, then said, “I just wanted to make sure you didn’t get to use that monster on anyone else.”
“Aw come on,” I begged, but to no effect as she just giggled again and slipped the necklace over her head, giving me a smug look as she did so.
“Besides,” she continued with a grin, “now you have to come back here after your classes. Bye bye.”
She waved at me. Groaning, I left her apartment, telling myself that it would only be for the day and that I’d keep the necklace to myself once I got it back. Still I couldn’t help feeling sorry for my little buddy.
