"Anything?" Steve said, between warm gentle kisses.
"Oh God." Lee gasped, panting, sweating, trembling. "Okay. Okay. Just... whatever you do, keep me safe, okay?"
"Always." Steve whispered. "Even if... I order you to grow to a C cup."
Instantly, erotic warmth engulfed Lee's chest. She pulled away from her lover and closed her eyes tight, hands flying up to her breasts and holding them with shaking hands. The sensation of feeling her boobs expanding, their flesh and weight growing under her palms, the strain as her small bra became tighter. She opened her eyes gasping and looked down to find her chest, just as slim and and proportioned as the rest of her, now had clear cleavage pressed into her bra cups, and visibly filled out her tank top with an obvious feminine swell.
"J-Jesus!" Lee stared, her eyes wide, her nipples hard and perky, perhaps a little larger too. On her slim body, with her thin figure, even such a modest gain in size made her look huge. She looked up at Steve, eyes locking, and saw his shocked and clearly pleased creeper smile.
She insinuated nothing, smiled coyly, and grabbed his hands in hers. She pulled her lover forward, and placed his hands on her bigger tits, gasping as she found they were also more sensitive to the touch.
Steve simply sat there... stared. He began massaging them gently, caressing her expanded bust. Pressing them together.
He looked at her pleased expression, looked down to her delicious brown cleavage, and promptly began making out again, hands everywhere on her body.
"I..." Steve gasped, in between passionate kisses and intense petting. "I... order you..."
Lee moaned, hearing the words and bracing herself.
"I order you to grow to a... to a D cup!"
Lee began vibrating with pleasure. Between the kisses and her breasts surging even further forward, the feeling was indescribably delicious. For a moment, her bra grew ominously tight, and her now huge constrained boobs strained against it, pulsating and swelling madly, but little had to be done. With a ping the clasp snapped apart and freed her growing boobs, allowing them to subtly pull downward from their natural weight and continue their growth unabated.
The make out session reached it's end, and both panting, the two lovers parted and leaned back to admire the new change.
"Damn." Steve giggled, staring at two huge and heavy boobs, nipples poking through the fabric of Lee's tank top obscenely.
"You owe me a bra." She said with mock annoyance.
They stared at each other and again Lee smiled slyly. She reached for the bottom of the tank top and pulled it up to her waist. At her current chest size this revealed her perky nipples.
"Damn!" Steve gaped, realizing they were even larger and more attractive than before. He reached forward gently, placing his hand under one breast, and gently hoisted it up under her tank, feeling the new size, the new weight, the big softness of it.
"Oh, oh!" Lee giggled. "Okay... not minding that at all."
Steve stared into her eyes, began lowering his mouth to meet her nipple, never breaking eye contact, and looked for her approval.
"Oh!" Lee's face twisted into anticipation. "Please!"
Her lover began by running a gentle tongue tip over and around her nipple. It pulsed in response, sending warmth and erotic pleasure to her pussy, and she seemed to melt. He took the larger thing into his mouth gently, closing his lips around her areola, and with the greatest care he began to suck.
Lee leaned back further, moaning, and watched him dutifully pleasure her increased breast. His other hand, meantime, snuck under her shirt and lifted it, her two large bare breasts now evident in his hands.
This continued for some time...
