Chapter 6: Yes, grow those assets.

Just before he leaned in, Andrew looked down at Stephanie's nearly flat chest, hidden by her hoodie, and clicked the device in his pocket. He didn't wait to see if it worked, his lips already against Stephanie's. They kissed slow, but with heat, each of them taking a sharp breath as their lips met. It was a good kiss, made better by the sudden, heaving mass that Andrew felt against his chest. Stephanie's breasts were growing, pushing Andrew away. They felt even larger than last night, when he tested the device from his bedroom. He couldn't help but grasp for them, squeezing the firm flesh over her hoodie while his lips were still against hers.

"You don't want to go further than last time?" she teased him, breathing soft against his mouth.

"No," he breathed back, slipping a hand underneath her hoodie and pulling it above her huge, wobbling breasts.

Stephanie released a soft gasp as Andrew's hands slipped over her new tits. His fingers sunk into the soft flesh, her hard nipples smothered by his palms. He leaned in, mouth open, but paused.

"Can I...?"

She nodded and Andrew took her nipple in his mouth, sucking on it while he felt up the other breast. Stephanie's legs reached for Andrew's, shaking just a little as he suckled at her tits. He went back and forth between both of them, leaving each hard nipple wet with saliva. Stephanie pulled him back to her mouth and they kissed again, separating only to remove their tops. Andrew lay on top of the slender teen and their lips met forcefully. Andrew kept a firm hold of her huge tits as they kissed loudly, hips grinding more and more aggressively.

Andrew dragged his bulge between Stephanie's legs, pushing with heat and slipping off of her pelvis. Her leggings were splotched and wet and she gasped with each little push. The teens dry-humped at each other sloppily, their lips wildly smacking and echoing in the small bedroom.

With sudden inspiration, Andrew grabbed Stephanie's leggings and pulled them down, revealing her wet, pink pussy. He stared at it, momentarily paralyzed by the sight. It wasn't hairless, but neatly trimmed, glistening in the low light.

"Sorry about the hair..." she said from above him.

"No, it's hot," he said, diving into it.

Andrew ate her recklessly, no idea what he was doing, but savoring the sweet, sharp taste of Stephanie's sex. She moaned gently, hand in his hair, writhing slowly at his touch. He did his best, mouth and tongue pushed deep between Stephanie's legs, but his inexperience was obvious. After a minute she pulled him up into a long kiss, her pussy juices splattering across her chin.

"Let me see you," she said, tugging playfully at Andrew's sweatpants.

Andrew leaned back and tugged them away, taking his underwear too, and showing off his erection. Stephanie bit her lip and moaned a little, spreading her legs for him. Andrew, though, wasn't quite ready for that. He stepped his knees over her and let his cock rest between Stephanie's new, huge titties. She giggled and playfully rolled her eyes, pinning her breasts together with her wrists. He grinned sheepishly and pushed his cock between them, sliding through her cleavage. A light layer of sweat helped him through, and Stephanie spit on his cockhead when it emerged in front of her mouth.

With a grunt Andrew fucked Stephanie's tits, helping hold them together while his hips slapped gently against the underside. She bit her lip for him, breasts wobbling against his ****. He held her tight, increasing his pace. It felt so good to pump his hips freely, though with each push there was less fluid to lubricate the passage, and he pulled away.

"Come on, baby," Stephanie cooed, legs spread wide.

Andrew settled between them, cock resting on her smooth skin. He glanced up to her aching, needy eyes, and back down to her pulsing little pussy. It was about to happen, he was about to have sex...

The first moment of penetration elicited a gasp from Stephanie and a grunt from Andrew. He slid easily inside, so easily he fell forward and immediately pushed as deep into her as he could. Their hips slapped together once and then he settled on top her, cock twitching in her tight hole. It spasmed around him and Andrew nearly burst right there. Andrew wasn't sure what to do next, so he started to thrust as fast and hard as he could.

"Oh, fuck!" Stephanie shouted, not ready for such an **** on her pussy.

Andrew huffed hard, body tense, slamming his cock into Stephanie again and again. She writhed beneath him, eyes closed tight. Her pussy gushed. Andrew didn't realize he slipped in a little too easy for this to be her first time, but he didn't care even if he did. He was far beyond himself, his cock squeezed tight by a perfect, tight hole. His arms shook, barely holding him up, while his hips continued to slam against Stephanie's slender body.

It wouldn't be long for Andrew. His arms gave out and he landed on Stephanie's soft body with a grunt. He didn't stop his hips, fucking Stephanie's pussy as hard as he could. She moaned beneath him, mouth hanging open. Her big, heavy tits fell to her sides, shaking with the rest of her body with each hard thrust.

"Oh, oh, I'm almost there," she moaned, the dragging of Andrew's pelvis across her clit pushing her toward the edge.

"Me too," Andrew grunted, eyes rolling back as his cock seemed to expand, suddenly ten times as sensitive.

"Keep going! Keep going!" Stephanie shouted, clawing at his back.

Her legs closed in over Andrew's hips and he found he could barely pull away at all. He shoved himself inside her, just the last inch or two, pushing deep into her, nearly over the edge.

Andrew reached it first. His face fell into Stephanie's neck as he exploded, moaning helplessly as his throbbing cock let loose inside Stephanie's tight little cunt.

"Don't stop! Don't stop!" Stephanie shouted, hips writhing beneath Andrew.

He did his best to obey, pulsing his hips against her, just teasing her sensitive clit. His cock had finished blowing his load, but it was so sensitive now that Andrew could hardly stand it. He kept going, hoping to finish Stephanie. She was doing most of the work now, hips grinding hard with his still-hard cock inside. After a moment of this Andrew grasped for her big tits, massaging the firm flesh and teasing her stiff nipples.

"Oh yes, oh yes, oh yes!" Stephanie chanted, gritting her teeth.

It was only a few more moments before Stephanie finished. Andrew felt her tight pussy flood suddenly, soaking him further and dribbling onto the sheets below her ass, already wet from sweat. She barely suppressed a very loud moan, a muffled scream just escaping her teeth.

The teens didn't move for a long moment. The extended silence hung between them, heavy but not unpleasant. Andrew moved first, sitting up and withdrawing his waning erection from Stephanie's stuffed pussy. She gasped, louder than she wanted, as he fell out of her, the smallest trail of thick cum following it.

"Wow," Andrew said, sitting awkwardly over Stephanie.

"I agree," she said with a smile, sitting up. "You know, if this is what you wanted, why did you wait so long?"

Andrew wasn't sure if that was the effects of the device or her true feelings, so he played it safe. "I don't know. I just decided to go for it."

"I'm glad," she said.

She grabbed her hoodie and began to slip it over her head. "Not to be weird, but you should probably go. It reeks like sex in here and if my parents catch you around it'll be hell for me. I'll just be able to tell them I was helping myself otherwise."

"Sure," he said, hurriedly gathering his clothes.

She shooed him out the door a few minutes later. When he looked back at his front door Stephanie was already at her window, waving to him before closing the blinds. He didn't have time to wave back, but he did grab the device and click it once, focused on returning her body to normal. He would be able to change it again later, if he needed. He wondered, for a moment, if she really was interested in him. What if he had just made a move before all this? It kind of hurt him to think that way, so he put it out of his mind and stepped into his house.
