Karyn finished the call with her mother and hung up. She looked around at her now huge surroundings and did a little exploring on the desk. Jon was able to sense when she was trying to move and moved his hand in the right direction. For Karyn it felt odd, in her mind she was doing to action of walking but in her current state she had no legs to move and she didn't feel the ground under her feet, she was just sort of gliding to her destination.
When she approached what she was heading for she stopped and stared at it. Before the change she had placed her rings in a cup on Jon's desk. Now she reached into that huge cup and with some effort was able to lift one up. She marveled that what was once a tiny thing that fit on her finger was now something she could wear as a belt. It was too heavy for to lift over her head though so she called up to Jon,
"Could you help me with this?"
Jon took the ring from her tiny hands and as she held her arms over her head, carefully slid it down around her miniature body, where it rested at the base of his new finger.
"How do I look?" Karyn asked, doing a twirl which due to her attachment to Jon's hand was more of a half twirl.
Jon looked down at the gorgeous girl attached to his left hand, all kinds of thoughts running through his head, thanks to the stone he remembered when they made the decision to do this and almost jumped for joy when he recalled the part where Karyn said she would be up for all kinds of stuff when she was his finger. He felt an immediate tightening in his pants and replied,
"Y-you look great!"
One of the effects of the joining was that Karyn was aware of her host body's feelings and right now she felt a surge of arousal. She made Jon raise her to his face, a feeling that slightly disoriented her with the speed of ascent, and said to him,
"I was going to suggest you get me my clothes but I can tell you have... other plans", Jon blushed and she went on, "Well, what are you waiting for? Let's do it!" as she began her descent toward his crotch.
