Tails didn't dare make a sound, just watching the two girls giggle and bounce their newly grown assets around like they were playthings. This was something out of a dream, or an erotic movie of some kind...not that he would know, of course...there was only one erotic thing he'd ever watched before. The thought of that something gave him his voice back as he cleared his throat and got their attention. "Well, ladies, now that I've fulfilled my end of the bargain, I think it's time you do the same."
Blaze stopped moving, her breasts doing the same a few moments later due to their bounciness, and she smiled and nodded at the fox boy. "You're right Tails, thank you. You've made both our dreams come true." She grinned deviously. "In fact...Amy, I think he deserves a little extra reward, don't you think?"
Amy smirked deviously. "You read my mind." She began walking towards Tails with a seductive sway in her hips with each step, which had also grown wider to accommodate her newly grown rear. Her thighs even became thicker as well, giving her exactly what she always wanted. The perfect hourglass figure. "You like what you see, fox boy?" Amy teased as she turned around and bent over, flaunting her massive ass to his face. "Look at what you helped create."
"I...uh..."
Then Blaze came up behind him, and Tails gasped in so much air through his mouth he squeaked as an incredibly ample bosom squished into his back and a pair of arms wrapped around his neck, turning him into a sandwich as both sexy ends of the female anatomy were suddenly on him at once. "You fulfilled my dream and eliminated a lifelong insecurity of mine, you deserve to enjoy yourself."
He couldn't move, even moving his arms back only made his elbows dig into Blaze's chest, making him even more panicked as his nose bled again. "I-I-I c-can't, I don't, please!"
"Aww, he doesn't want to play." Blaze pouted. "Well, I guess we're just not enough woman for him Amy. Better give him what he really wants."
"Yeah. Let's give the real booty queen a call." Amy took out her phone and began dialing up Cream. Even when she wasn't fully herself, she at least was still a woman of her word. Even with her big ass pressed against Tails's body.
"Y-You're actually doing it!" Tails was distracted from his predicament for a moment when he heard Amy talking to Cream over the phone, and that brief moment was enough to get him to loosen up and actually enjoy himself. "This is the best day of my life!"
Amy giggled hearing Tails's response just before Cream answered the phone. "Hey Cream. Yeah, I'm good. Say, you're not busy today, are you? ... Good. In that case, you wanna meet up with Tails today? He's got a biiiig surprise for you." Suddenly, a loud excited voice came through the phone, causing Amy to recoil back a bit before resuming. "Y-Yeah. He'll be over soon. Okay. Alright, have fun!" She hung up and straightened herself back up to face Tails. "Well, you better not keep the lucky gal waiting!" She said as she pat Tails's head. "And...you'd better bring your growth ray with you. She's gonna loooove it!"

What good are big curves if you don't use them? And no one is more deserving of getting the first feel than the one who gave them in the first place. But this is just the appetizer...Tails is still gonna get the main course in the form of a growing bunny girl. You can read the full story HERE.
