"That was... interesting..." John thought to himself as he sat on his bed, checking to make sure his junk was all there. "How did that even happen? Well, easy to find out."
"I wish I knew why my wish was granted." The information flooded his mind. Some guy had been given this wishing ring by an old lady, lost it, and then John had found it. A smile came to his lips.
"Awesome, I can wish for anything! I should probably be careful though. First of all, I wish no one could take this ring off my finger but me!" Nothing seemed to happen. "Did it work? I guess I'll find out when someone tries to take it from me", he shrugged.
"Now it's time to have some fun..." John got up and looked himself over in the mirror. "I'll start with something simple. I wish I had C-cup breasts." His nipples started to tingle as he felt a warmth under his shirt. He could see them standing at attention. Reaching inside to feel himself up, he could feel the flesh puff into his fingers, growing larger and larger until it settled into a pair of C-cup breasts.
"Sweet!" John exclaimed, groping himself. "Mmmm... I'm going to have a lot of fun with this."
