The water level seems to start rising. Noticing this, you both inch your way out of the water. As you continue pleasing your girlfriend, it seemed as if your manhood decided to suddenly abandon his post.
“Why’d you stop?” Lisa asks.
“I didn’t mean to.” you say in an oddly feminine voice.
“Your voice!” Lisa shouts. “It sounds like a girl’s.”
In surprise you leap up and cover your mouth with your hands, finding that they are a somewhat daintier; like Lisa’s. Your face is also much smoother and more rounded. Only then do you finally start feeling the changes to your body as they move from your already feminine extremities inward. Your hips spread and your shoulders narrow. Your waist caves in as breasts bud from your chest, swelling to a respectable B-cup.
“What’s happening to me? Lisa…” You call out toward Lisa, only to see her somewhat entranced and wrapped in a pink glow hovering above the ground. You didn’t have much time to observe what was happening to her before you were caught in your own trance and rising from the ground.
Your ears stretch to a significant length; and you feel something push its way out of your back at four points. Muscles in your back rearranged themselves to accommodate the ever-growing new limbs as they spread long and thin.
Once your trance breaks and you set back down, you look at Lisa to see large, insect-like wings adorning her back. Between the look on her face and the sensation on your back, you just know that you have them, too.
At once you both shout; “Holy crap; we’re fairies!”
