June put her hands behind her head, leaned back against the couches, causing them to creak, and let Ty have his way with her giant sized body. She was over fourteen feet tall now and her feet were growing closer to the wall on the opposite end of the room. She watched as her miniscule step soon leaned down in front of her vent, grinning with boyish excitement, and made a fist in front of her pussy. He looked up at her expectantly.
"You little pervert." June blushed, smiling. "Go right ahead. Stick it in!"
Ty pressed his fist against June's sopping and exposed passage and with nearly no resistance his entire hand slid in.
June's shock was palpable. She raised her knees off the floor a little and gasped, a great big huff of air in her great big lungs.
Ty's initial startlement wore off quick and he pressed his arm forward, slipping into a slick and very excited hole that gripped his arm along its length. He began thrusting his entire arm into the giant woman, realizing that her passage was growing looser by the second. When Ty looked up, he was met by a blushing and panting June, eyes closed, her head nearly reaching the ceiling again. She was sixteen feet tall! Well, might as well keep going before she got too big. June began to moan loudly, her amplified voice echoing through the room, as little Ty thrusted his arm into her pussy madly. As she grew bigger and looser, he found himself up to the shoulder inside of her, squishing and gurgling as her fluids poured around him and her inner walls gripped as best as they could.
"Oh, that's doing it!" June cried. "Oh God, oh God, here we go again!" The twenty foot tall giantess suddenly began to shake her thighs and grabbed her massive tits, now more like bean bag chairs to Ty. He kept thrusting and slapping around in her pussy until with a rumble of a moan that shook the room, June came!
With a gasp of shock, Ty pulled away quickly as his step mom's increasing size surged rapidly. With a cry, just avoided her huge ass thudding into the floor while she came, as she passed through twenty feet tall quickly, cumming, and hit twenty five feet in seconds, audibly stretching. Fuck! Fuck! He had forgotten to remove the grow from orgasm condition.
He feet hit the far wall and began to press on it while she positively crushed the old couches under her spasming back. Her head bumped the ceiling and began to curl under it at thirty feet, while the floor began to groan beneath her awesome weight.
"T-Tyyyyyy!" June cried, shaking the walls. "T-Too---" She gasped as her orgasm began to subside and opened her eyes, shocked as she realized she had put giant feet holes in the drywall and had destroyed much of the living room.
"D-Don't move." Ty whispered.
"I'm not." June gasped. "Oh my God! I'm... I'm a fucking giant!" She stirred only slightly and her massive knee smashed the TV off the shelf and shattered it.
"Okay." Ty blinked. "Take it easy. I'm going to shrink you back down."
"O-Okay..." June whimpered.
The sight of enormous June made Ty very horny. He looked at his still dripping hand and arm and licked some of her fluids off. The smoky flavor hit him and he gasped.
"Hey!" June snapped, gulping. "Ty!" She was still growing! Her shoulders were hunched against the room and she had curled her knees up to pull her legs in. She was now the *size* of the entire living room!
"Sorry!" Ty apologized quickly, gasping. "Fuck, okay!"
