The next morning, waking up felt quite surreal. I remembered the events of last night, smiling to myself. I looked to the other side of the bed, but Molly wasn't there. He then focused on the noise coming from the bathroom. The shower running was a comforting noise to him, and he always enjoyed showering together with Molly. Today, he figured he'd surprise her. With a smirk he got up, not needing to undress, since we'd gone to sleep nude. I gently opened the already ajar bathroom door, hearing Molly's beautiful voice. She always was so good at singing, and her humming could put me to sleep with it's serenity. I sighed a happy, infatuated sigh, as I stepped into the shower with her. She had her back turned to me, so I let my hands trail down her spine from her neck. She shivered, turning around and attacking me with kisses. I loved her and she loved me. As we broke from our flurry of kissing, she smiled at me. "Hey you... Thanks for last night." She said seductively. I smirked back, kissing my way down her neck, and around her chest. "Mm... How about you let me show you how thankful I am" I said back, kissing each of her nipples. She moaned softly, running her hands up her body, and cupping the sides of my face. She guided my head downward, to between her legs, and let out a satisfied gasp when I started pleasuring her. I came back up only when her breath was heavy and ragged, her body tense from her orgasm. I smiled at her, as we embraced once more. Breaking the kiss, I asked. "How did you sleep?" She smiled, looking away with a shade of red coloring her cheeks. "I slept really well... thanks to you. I wasn't in as much pain last night." I nodded. "So you... changed more?" I asked. She nodded in response, seeming quite calm about it. "Yes, I did... My tail is a lot longer... and, thicker... now." As she said so, I felt something grazing my leg. I looked down, seeing Molly's tail sticking out from between her legs, caressing my thigh. My eyes widened. "How long is it now..?" I asked, as I kept staring at it. Molly looked down at it and shrugged. "I don't know... maybe 30 centimeters? It's also as thick as my arm" She said, a hint of pride in her voice. "I've been trying to get more control over it this morning. How do you like it?" She said, gently grabbing my chin and bringing my face to face hers. I swallow hard. "It's... nice, actually." I said, my heart beating a little faster than normal. My girlfriend has a tail for crying out loud! Her eyes light up as she remembered something. "Oh yeah! Another thing happened during the night!" She said, holding out her hands. I take them, examining them. At first everything seems normal, but as I look closer I notice what's happened. In between Molly's fingers, blue-tinted, semi-transparent webbing had started to grow. It was about halfway to the middle knuckle, and as she spread her fingers wide, the webbing stretched with them. "I'm growing webbed hands." She says, matter-of-factly. "And here, look" She says, pointing down to the floor. I look, and she spreads her toes wide, enough for me to see thin, translucent blue-tinted webbing had grown halfway to the tips of her toes. "My feet too." She says, looking at me. I'm in shock, and when I meet her eyes, I'm almost disturbed by how calm she is. "Aaron, do you understand..? My hands and feet are becoming webbed." She says, grabbing my shoulders and shaking them slightly. I nod, looking her in the eyes. "We're gonna have to explore your body more then.." I said, managing a flirtatious smirk. "How do you feel about this?" I ask her. She sighs and looks down. "I don't know... I don't know..." She says, putting her hands on his chest, burying her face in it. "I'm... a freak...!" She says, starting to sob. I embrace her, comforting my Molly. "Baby... you're gonna be alright. You're gonna get through this, and I'm going to be by your side the entire time. I promise you that".
During the day, we spend our time doing things we like together. We play videogames, board games.. we paint, cook, and talk. It feels like any normal day if I disregard the tail that's attached to Molly. By the time we've gotten to bed, it's late. Molly stands in front of me, as we're both naked once more... She spins for me, showing off her body, her tail... everything. She cups her hands on the sides of my face, bringing me in for a kiss as we lose ourselves in passion once more. Unbeknownst to both me and Molly in our devil's tango, a small caudal fin sprouts at the end of Molly's tail. It grows slightly bigger in a rush of change as she orgasms for the second time today.
