Jo was really turned on by watching the twins, and she began to masturbate as she watched. Thanks to Sharon's earlier wish, she knew what to do, and soon, she felt a wave of pleasure from her orgasm. She lay back, staring at the ceiling. Who knew being a girl would feel so good?
Then she felt weight on the bed, and saw a pair of innocent looking young girls crawling towards her, identical smiles on their faces. They began to kiss her body all over, and one climbed up to straddle her chest before leaning forward to kiss Jo, her small hands on Jo's breasts.
The other girl lay between Jo's legs, softly kissing her tummy and the area around her pussy, then began to sofly nibble her soft skin.

Sharra made a face. "Ok, how about, if she wants to use the ring to change us, she has to make love to us first."
Sherri smiled. "I like that...oh damn you, Jo...I wish that if Jo wants to use her ring to change either myself or Sharra in any way, she has to make love to both of us first." It wasn't perfect, but at least some effort would be required. And the results would be pleasurable.
"Should we have Jo make more of us?" Sharra suggested.
