Bobby saw that Kaitlin had gotten up and gone to the mirror in the bathroom. He smiled and wondered from the night before. Clothes and shoes were tossed around... Mark and his girlfriend were somewhere in the house Bobby figured, remembering how they had all staggered back home together from the bars.
Initially, Bobby had planned to use the ring as a wish granting device, but then either he or Mark (he couldn't remember who) thought up the idea to have the power transmitted by their dicks as well. He hadn't thought it would work, but they decided to try it anyways.
He remembered that he and Mark had both aged their girls, he just couldn't remember how or by how much!
What happens next:
-Bobby explores Kaitlin's new age.
-Bobby and Mark take the weekend to screw and wish Kaitlin and Jenny into (extreme?) old age.
-Instead of swapping years with other women, Mark and Bobby absorb Kaitlin and Jenny's life force and become stronger, more masculine and irresistible to women.
-At the end of the weekend, they pick up Amanda from her friends and, in between bouts of play, drain her to partially restore Kaitlin and Jenny.
