During the drive to school Jen noticed little things strange with her boyfriend. The changes were subtle but they were slowly adding up. The most noticeable changes were to his face. His features were gradually softening and rounding. His skin was getting clearer and not even a trace of stubble was visible. Occassionally he brushed aside a bang, his hair having grown a few inches since the trip had begun.
Jen didn't realize exactly how far the transformation had gone until they pulled into the parking lot and Jim started making out with her. Jen felt strange kissing him, running her hands through his now long black hair. It was when she went to caress his chest expecting to feel hard pecs did she realize why she had been feeling strange. Instead of feeling hard muscle she felt soft flesh pressing against her hand. She jiggled it to make sure she was actually touching a breast and Jim practically purred with pleasure.
