Tails cringed, a sharp pain arcing thorough his body. He stumbled, bracing himself against a desk. Amy stepped forward to help, only for a warmth to overwhelm her, flowing into her chest. Tails' namesakes flicked with excitement, his, or rather her body starting to shift. Her legs lengthened and filled out with subtle curvature, her hips widening. Her waist thinned, and her hair grew out, down to her shoulders. Her butt rounded out, small but perky, and her breasts rose, nipples poking out, erect. She let out little gasps as her body changed, her voice raising in pitch with every noise. Meanwhile, Amy's chest swelled out, pressing against her shirt. Both of their eyes shone pink and heart-shaped as their transformations took place, only fading when they were done, leaving both to fall to the ground, heaving for breath.
Amy came to first, touching her breasts as if to see if they had really grown. She gasped, at the touch, her tits still tender and sensitive from the growth. She felt little twitches of arousal, but managed to come to her senses upon seeing Tails. She rushed over, helping the vixen to her feet.
"Tails! Are you alright???"
Tails looked up, eyes flashing pink for a moment before fading back to a sparkling blue. Her face seemed to flush a little at the sight of Amy. She felt a sudden, strange desire for her friend. She put her arms over Amy's shoulders, drawing her face closer. Her lips looked so soft...
Tails blinked, realizing what she was doing and flushing.
"Uh, y-yeah! I'm..." She stopped, recognizing her own voice. Looking down, she gasped at the sight of her body, her blush growing even deeper. "I'm a girl!? I'm naked!!!"
Panicking, she pushed past Amy and stumbled into the bathroom, locking the door behind her. She looked in the mirror, gazing into her face. Her eyes were larger and cuter, with longer eyelashes. Her hair was slightly longer, framing her face in a cute little bob, and her lips looked slightly larger and softer. She blushed yet again, realizing that her face was just as pretty, if not prettier than Fiona's.
Her musings were interrupted as Amy knocked on her door.
"Tails? I'm sorry. I think the hammer I borrowed from you did this. The... 'Love Hammer?'"
"What!? That was a prototype!"
"I know, I'm sorry!" Amy said, "I have a spare dress I'm leaving in front of the door, it's not perfect but it's better than nothing..."
Amy walked away, waiting on the couch, until she heard Tails walking up. Looking back, she blushed. The dress fit her perfectly, the crimson dress standing out against her golden fur in a way that looked extremely pretty. Tails kept the brim of the dress held down as she walked, having no underwear to cover her privates.
"Um, h-how do I look?"
"So cute!" Amy smiled, rushing in for a hug, "You look absolutely adorable!"
Tails froze, feeling Amy's larger, softer breasts rubbing against her own tits in Amy's tight embrace. Her tails waved around excitedly.
"I-I don't have any underwear." Tails blurted out, pushing Amy away, before realizing what she'd just said. She blushed. "I mean- I- Uh,"
"Oh no, you're right!" Amy said, "Wait right here, I'll go get some! I need to pick up a new bra anyway..." Amy smiled, squeezing her B-cup breasts, "Say, do you think Sonic will like these...? Right, this isn't the time! I'll be right back!"
Amy rushed off, leaving Tails feeling a pang of rejection. She knew that Amy only had eyes for Sonic. So why did she feel this way...?
