"Are you feeling a change in any particular part of your body? My skin started itching all over and my legs went weak."
"My stomach itches and...uh...I can't think of a better way to say this, but...my crotch feels weird."
Unable to hold back any longer, Bobby began scratching under his shirt and rubbing his crotch.
Emma pulled off Bobby's shirt to reveal a gray color similar to her own working its way up Bobby's stomach. The color spread to his ribs and stopped. Similar coloration was reaching down Bobby's legs almost to his knees, but also seemed to stop there. But now he was rubbing his crotch with both hands.
"Oh god it feels like I'm shrinking..."
Bobby pulled down his pants to reveal the gray dolphin-like skin covering his waist area and crotch, and his penis was indeed gone. Bobby felt himself and found a slit where it used to be.
"Did the curse turn me female?"
Not believing what had just happened, Emma felt her boyfriend's crotch. Now Bobby squirmed for a different reason.
"I think dolphin's just tuck their equipment away until they need it" said Emma. Then she grinned mischievously. "Want to find out for sure?"
Emma ran her hand over Bobby's crotch again and felt strangely turned on. She remembered hearing dolphins were frisky animals, up there with humans and rabbits. Hell, sex might be a good way to relieve the tension. She was curious if her own parts were affected by her change; she hadn't taken her biking off since transforming.
