Dale’s thirst for may prove unwise…

"Having fun over there, Mikey?" Dale sneered, unable to resist mocking his newly buxom friend. He leered openly at Mike's heaving D-cup breasts, their sheer size and heft amplified by his scrawny frame. "Those things look pretty top-heavy for such a little guy!"

Mike flushed, suddenly feeling self-conscious and exposed under Dale's scrutinizing gaze. He tugged at his strained shirt, trying in vain to cover up the distracting wobble and jiggle of his fresh cleavage. "S-shut up, asshole! You're just jealous you didn't get the tits."

Dale barked out a mocking laugh. "Yeah, you caught me. I'm absolutely devastated I don't have to deal with those floppy bolt-ons weighing me down!"

His eyes gleamed with wicked mirth as he plotted his next move. Mike may have scored the first strike by saddling him with a bimbo booty, but Dale wasn't about to let him keep the upper hand for long.

"Knight to C3," he announced, sliding the piece into position with a decisive thunk. He didn't miss the way Mike's eyes widened fractionally, clearly recognizing the trap being set.

But the smug grin never left Dale's face as his friend countered with, "Pawn to E6."

Gotcha.

"Queen A1. Queen takes Knight," Dale all but purred, using his busty queen piece to capture Mike's hapless knight with a flourish. He sat back, arms folded across his broad chest as he waited for the bimbo magic to take hold.

At first, nothing seemed to happen. Then Mike gasped, his newly enlarged breasts heaving dramatically as his arms and shoulders began to tingle and prickle. Dale watched, enraptured, as the fabric of Mike's sleeves started to strain and stretch.

Within seconds, the scrawny limbs were growing thicker and softer, shedding what little wiry muscle they'd had. Mike's forearms became smooth and slender, tapering into delicate wrists and perfectly manicured nails. The changes crept upward, his biceps melting away into the same pillowy softness as his chest ballooned with feminine curves.

By the time the transformation reached Mike's shoulders, his entire upper body had been utterly reshaped into an exaggerated hourglass figure. Breasts, shoulders and arms flowed together in one continuous, bimbo-fied swell of yielding curves.

"Oh man..." Mike whimpered, staring down at his newly feminized limbs. He experimentally flexed an arm, his delicate brow furrowing as he struggled against his diminished strength.

When he reached for his water cup, his weak grip immediately failed him. The cup slipped through his manicured fingers, clattering to the floor and spilling its contents everywhere.

"Wow, your arms are completely useless now, huh. Only made for stroking cocks.” Dale guffawed at Mike's dismayed expression, not even trying to hide his amusement. "With no muscles and those giant tits throwing off your balance, you're as feeble as a baby deer.”

He leaned back, openly drinking in the ridiculous spectacle of the bimbofied stud struggling to even lift his drink. Mike's plump breasts swayed and jiggled with each futile movement, their sheer size only emphasizing his lack of physical strength.

"Maybe you should invest in a bra, bimbo," Dale snickered, grey eyes glinting with dark delight. "You're gonna need all the support you can get lugging around that cow's udders!"
