When at last they neared the outskirts of the city, Steve felt like he might burst. Far from going soft again, Lee's road head had left him beyond turned on and eager for more sex, more changes, and more experimentation with her collar's limits. His balls churned and ached madly.
She must have seen his desperation mounting, as Lee put a loving hand on his shoulder and brushed his cheek. "Soon, Steve. Then we can play some more."
When he pulled the car up beside the apartment, he got out, fumbling with the keys, and his eyes went wide as he saw Lee get out. She was so much taller than normal. She hadn't just grown in proportion, she was just a little slimmer, her legs were just a little longer, but somehow she had also grown larger in overall size. He stared at her more willowy body and taller more statuesque height, and felt somehow dwarfed by his lover's new stature, even though he was merely an inch shorter than her now.
"Mmmm." Lee smiled, catching his lustful gaze. "You like this too..."
Steve took her hand gently, amazed, and began walking. As close as she was, he marveled at how she stood as tall as he did now. As he unlocked the basement suite, sweating profusely and hard enough to cut diamond, he held Lee's hand and turned to close the door. At the bottom of the stairs, they were all over each other once more, hands madly fondling each other's bodies and lips smacking eagerly as pure sexual desire took over them. Steve managed, somehow, to unlock the suite door, and they practically fell into the apartment together, still passionately making out.
Locking the door behind them, Steve grabbed Lee's firm ass in both hands and as they had done many times, she leapt up and wrapped her legs around his waist. Her light slim frame made her so easy to pick up, but now, with her added size, she was a much more substantial load on her boyfriend, hanging off him a little more than usual.
"Baby..." He grunted, struggling to hold her. "You're a little..."
She giggled and kicked off her shoes against the wall, letting them clatter to the floor, and set herself down on her feet. "Are you saying I've put on weight?"
Steve chuckled, and they began making out again in earnest, practically tearing off each other's clothes until their hot naked bodies were pressed close.
"Damn..." Steve gasped, admiring Lee's longer legs and slimmer form. "I like you this way..."
"Me too..." Lee said, tongue emerging to taste her boyfriend's mouth, trailing down his own and tickling the roof of his mouth. She reached down and placed his cock in a firm grip, pulling it tenderly, and looked him in the eyes. "But I could be taller..."
Steve's eyes widened, and with a forceful push he knocked Lee onto the couch against the wall, staring at her with maddened lust. "All right, you asked for it." He whispered, practically panting, with wet pre dripping from his cock tip. "I order you to slowly grow in size until I say stop."
Lee jolted suddenly, eyes wide, and threw her head back in shock, fingers gripping the couch cusions tightly and legs quivering. The shock to her body was instant, and she let out a deep and prolonged moan of pleasure as she felt a warm tingling overtake her entire form from head to toe. As it relented, she looked back to Steve and felt his hands on her knees. She looked down in shock as very little by little, she could see everything around her shrinking. In a minute, she had grown larger, and the pulsating warm tingling wasn't stopping.
She knew what was about to happen, but was still pleasantly surprised when Steve kneeled down, buried his face in her wet pussy, and began to firmly lick her clit. She grabbed the back of his head with both hands, moaning, and actually felt him getting smaller in her grasp.
"Oh... oh..." She tossed her head from side to side, feeling the tension building, and opened her eyes momentarily to find that her lover was now visibly smaller to her, as was the couch, the room, and the entire apartment. As she neared climax, blinded by pleasure, warmly, sweating, tingly, she opened her eyes and found her head on the wall behind the couch, just six inches away from touching the roof while sitting!!
Vaguely, she wondered how huge a woman she would be when he decided she was big enough, but all thoughts began to white out as he stimulated her clit with a smaller and more precise tongue, and she neared orgasm.
When Lee came, her cry of ecstasy sounded so much louder than usual that she abruptly frightened herself. At the same time, as orgasm racked her body, making her quiver sharply, her head bumped the ceiling and began to press upward. Instinctually, she hunched down, and soon her neck was touching the roof.
"Honey!" She cried, looking down past legs that nearly reached halfway across the room, and realizing she was hunched down against the ceiling. Still Steve's face was buried in her crotch, but she was too distracted to enjoy it.
"Honey!!" She said sharply, panicing as she began to fill the room, effortlessly pushing her lover away with her crotch and sliding off the strained couch onto the floor. Steve broke away in shock, licking his lips of her pussy juice, and looked up and up at a titanic Lee.
"Oh!" He realized. "Uh... uh... stop! Stop!"
At once, Lee jolted as her foot nearly touched the opposite wall, and she stabilized quickly at her current size. It took a moment to process. Steve stood and blinked, Lee looked back at him with wide eyes, and together they took in the sight of a woman who was now rather easily close to twenty feet tall. Even sitting in the open living area, she had to crane her neck down to avoid her head smashing through the ceiling, and carefully she pulled her legs in to shift herself lower, accidentally hitting the stereo stand with her massive foot and causing it to tumble over with a huge crash.
"Sorry!" Lee whispered, blushing deeply. "Uh... help?"
