As Sara touched the medallion to one of Bill's shirts she felt the shock that told her the change was going to happen.
Sara looked at Bill as she was holding the shirt and as she saw Bill bend over as she put on the panties she felt a momentary thrill. As Sara was feeling the change she also felt her new penis getting hard.
Sara's change finished as Bill was still thinking about putting on the bra she was holding.
Sara slowly walked up behind Bill and she put her arm around Bill, grabbing her nipple as she squeezed it.
Sara leaned into Bill's back and as her other hand went to Bills pussy she whispered "You know your idea of another round feels a lot better now to me."
Bill let out a gasp as Sara squeezed her nipple but was able to get out "I didn't mean like this."
Sara said "Think of it this way you will get to know what a woman feels like and it will make you a better lover when you change back."
Bill turned to say something but Sara kissed her as she pulled her to the bed.
The two of them went at it for the next few hours before moving into the shower again to clean up.
