Ty found himself naked and horny standing at the top of the stairs. He felt like a solid God as he looked down upon the kitchen. Past that, June was sitting in the living room on the recliner, a half drunk bottle of vodka and an empty glass full of melting ice sitting next to the chair. She was half cut and watching reality TV.
"How classy." Ty grinned, and willed himself invisible to June. She wouldn't sense him unless he wanted her to. Ty made his way down the stairs and stood right in front of June, his hard cock bobbing at her eye level. His step mother failed to see the 11" cock in front of her face, though, and seemed to still be watching TV.
"Hmmm." Ty considered. "Now just what can we do to you, dear June?"
She wasn't the most attractive middle aged woman ever, but she was still pretty in an alchoholic bitch step mother kind of way. June stood an even six feet tall. She wasn't fat, but had a little plumpness in her hips, ass, and stomach. Her boobs were hardly Dusty's titantic EEs but a nicely sized 32C that needed support to stay perky.
"Maybe..." Ty grinned. "We should blow up your boobs a little, huh? Nice and slow, so you don't notice at first, but you will notice them growing." Ty sat on the floor, watching, and smiled as he gently stroked himself. "Now start growing, June."
As she watched TV, Ty's step mom noticed a strange tightness in bra. She looked down, saw nothing weird, and adjusted her bra straps. She had just bought the bra a few days earlier, so maybe it was still wearing in. She yawned, poured another drink, and sat back, sipping as she watched. "Ha, stupid midgets." June laughed, before noticing again her bra was tight. In confusion, she set down her drink. "Damn bra." She peered down her shirt and frowned. "Damn thing is squeezing my tits." She sighed, frustrated, and reached back to unclasp her bra. This immediately let off the pressure and she resumed her drinking and TV watching, flinging her bra across the room.
Now her shirt was getting tight. This caused some confusion, and June looked down once more in annoyance and found herself staring at two round, firm, big tits. "What the hell?" She gaped, and her hands shot up to touch her boobs. There was a lot more to grab. Not only that, but they were tighter, firmer, not saggy like they had been for fifteen years. "Holy... shit." She let go of her boobs and marveled as they grow like slowly inflating balloons in front of her eyes.
Ty was laughing, watching June's childlike wonder.
"N-No..." June gasped, standing up and staring. She was now quite easily up to a firm D cup. And still getting larger. She hefted her boobs in her hands, squeezed them, and found them very real and heavy. "Fuck!" She cursed. "This is impossible." She had never heard of tits just spontaneously swelling up before. Maybe it was something she ate, or... or... her jaw dropped again as they kept growing under her hands. They were getting huge! Now the size of two luscious cantelopes. She fondled her boobs experimentally and found they were not only growing in size but sensitivity. She felt around, raised her top in curiosity, and marveled at the two jutting orbs still swelling in front of her. She blushed in arousal, this was so sexy. She was starting to give Dusty a run for her money.
With breasts still swelling, June began to walk upstairs to the bathroom. She missed Dusty snoring away on her bed and closed and locked the bathroom door behind her, still holding her tits. Of course Ty had followed, and now stood beside June as she stared in the mirror. She had removed her shirt and was now topless, holding her breasts. They were approaching the size of basketballs.
"Wow." June gasped, sensuously rubbing her ballooning flesh. She smiled, staring at her tits in amazement, and squeezed them each in her hands. She caressed, rubbed, and began to firmly massage them. Ty melted as June moaned deeply and threw her head to the side. She was now past basketballs. Was there even a cup size for those monsters? June frantically began tweaking her nipples, rubbing her tits with open palms, marveling as she found her areola and nipples were bigger too. It was too much of a turn on. June stared for a few moments more, watching herself blow up to ridiculous size and shape.
And then... Ty gave her a wish. The bigger she got, the more of a turn on it was, and June had to get off.
