"Oh definitely" you say to her, with your voice low and smooth while practically drooling. "But I'd like a little more to hold on to." You move to Ava turning her around to you and you start to kiss her long and deep. While your tongues wrestle, you silently wish for her butt to grow. Your hands move down her back to cup her ass and you feel the growth start. Where your hands only laid on top of her butt before, they slowly get raised up until they seem to be growing to fit your hands.
"Ah fuck! Your ass feels so good Ava" you say moving your left hand to the small of her back while the other explores this new bubble butt of hers. Ava always had an impressive behind: you imagined feeling and rubbing it for years. But now it juts out almost a foot behind her and extends almost a third of the way down her thigh. Its still is perfectly round and full and as the two of you squirm while you make out, you can feel the strong muscles churning inside. Moving your hand to the side of her growing silhouette, you feel her hips start to widen to accommodate the large growth. You feel her thighs thicken as well to support her strong new asset. Moving your hand back to the fullest, juiciest part of her ass, you decide to test how far your new friend will go. You gave her a light pat on the ass, but she says nothing as it jiggles. You try again, a little harder this time. She giggles while you kiss and starts to pull you down closer to her. You're both kneeling on the ground when you go for the dream shot, what you've been waiting for. You find the biggest roundest part of her naked ass and you squeeze her flawless cheek.
She moans in your mouth, her intoxicating warmth spreading through your insides. You break away from her and open your eyes to behold her new form. You look down first to her incredible new behind and run your hands down her curves. That last squeeze seems to have stopped her growth, but she's perfect. Her skin is smooth and perfect, completely free of any stretch marks or cellulite that might have appeared naturally. Your hands glide seemlessly over her hips which have grown substantially to accommodate her new back load. Her thighs and calves are ripped with toned muscle ready to support her during any... activities she might have in mind for later.
You look back up at her face. Ava cheeks are still blushing and her lips are pink and pouted from how aggressively you two were kissing. You look into her eyes and you see something that had never seen before. Being her friend, you had seen her crush on other guys before. But Ava had a sparkle in her eyes that hinted at something new. Desire?
"Oh my... Danny?" she says, her voice quivering.
"Yeah Ava?"
"Where did you learn to do that?"
"Guess it just comes naturally, babe." Cockiness aside, I honestly don't know. I've only ever been kissed once before and it was only a peck after I found her lost dog. "With you, it just comes naturally."
"Oh... Danny?"
"Yeah, Ava?" She cups her delicate hands on my jawline.
"This comes naturally too" she says as she practically pounces me onto the ground. She squats over me in the alleyway pulling my mouth up to her hers in a hot intense kiss. She slowly starts to grind her dripping puss on top of my bulging crotch, lething me know that she wants...needs more. I try to pull to take control but her powerfull new legs keeper me pinned below her. I try to speak "Ava are you sure you want to do this?"
She breaks away for a brief moment. "Danny a few hours ago, you were just my friend. Now I have this burning deep inside me and I need you. I need you inside me!" She goes back down to me for another kiss and starts to pull at my belt buckle. Now I'm happy she wants this so bad. Believe me I'm more than estatic. But now that I know this is a sure thing, I'll need to make a few adjustments.
