I stared up at ten foot tall naked Michelle standing in the alley and couldn't help but let myself get hard.
The new giantess noticed immediately. "Joe!" She gasped. "You're hard. Y-You... like this?"
"You... you're so big." I said timidly back.
"Wow. You know, I wanted to get your attention, but this is... this is something else." She giggled and twirled her long brunette hair. "I'd ask if you like what you see, but that's obvious."
Indeed, I liked what I saw and then some. Her scale was amazing, her giant breasts so pert and perfectly sized. Her nipples hard and perky from the cold. Her body tight, healthy, and shapely everywhere it needed to be. I wished her bigger still. Twelve feet. And I wished she'd start to *like* her growth.
"You're getting off on my size, aren't you?" She leaned down seductively, hands behind her back, showing me her huge breasts. At once, she shuddered and went down on her knees. "Damn... you're going to jizz your pants, Joe, cause here comes more!"
I watched in rapture and my cock grew stiffer as Michelle gained two more feet. Again, growing in proportion, she went down on all fours in the alley and moaned loudly as she grew. Stretching, expanding, all of her making a delightful creaking noise.
"Oh, Joe!" She said, licking her lips. "This is so weird. So fucking sexy! Quick! Let's do something before I get too big or change back or whatever the hell is happening to me."
"Oh, wow!" I gasped, and quickly dropped my drawers. The giant Michelle watched patiently as I got naked in front of her huge form.
"Mmmm... that's it, little man."
