Harley Quinn uses her boobs to knock Batman out one final time

Batman hung from his chains, head down, breathing heavily. He'd been here for weeks now. Any idea he'd ever come up with to escape had been short lived, and failed at the first step each time. Not that he had much time to make plans - Harley saw to it that his waking moments were both short and few.

He lifted his head at the sound of light, nimble footsteps coming towards him. He saw Harley Quinn strutting into the room, stark naked, sticking out her impressive chest with pride. Feeling the crotch of his batsuit starting to tighten and strain again, he lowered his head and groaned weakly at the sight of her.

“Aw, don’t be like that, Bats!” she chided teasingly, her posture dripping with arrogance and confidence. She skipped up to him, and slid a hand behind his head to take hold of the nape of his neck. She pulled up his head slightly, to look into his dim, weak eyes with her young, bright and sparkly ones. She wore a cheerful smile on her face. There was a light, glimmering sheen under the warehouse lights, all over her nude body from a layer of girly perfume she'd applied.

“I even got myself all dolled up and womanly for ya. This is the last time I’m knocking you out, after all! It’s a big deal! You should be happy!”

He groaned again.

“Y-you’re… crazy…”

She smirked, and started gently stroking his throbbing dick with the back of two fingers. “Shhhh…. Shhhh, it’s okay….” she cooed, pulling him into her sweet-smelling cleavage. He gasped faintly as she pulled him in, the tiredness from the association of stimulation to his cock with rest starting to wash over him. His face was engulfed by her womanly assets, and he let out a sigh as he breathed in her scent.

The addle-brained Batman started to quietly murmur unintelligible objections into her soft chest, not heard by Harley beyond weak vibrations through her generous bosom. She grinned as he starting slowly beginning the drifting descent into a snoozy slumberland.

“It’s alright, I know it’s scary…. mommy’s got you…. Just feel good and go to sleep, alright? Just feel good…. there’s nothing you can do now, mommy’s got you… just go under… let me put you under with just this smother… let me just smother you out cold, caped crusader…. mommy’s here for you….” she comforted him, stroking the back of his cowl with the hand holding his weakly resisting head in place.

"M-mommy?" he grunted faintly, confused and half delirious, as his mind faded.

"Yes, that's right..."

"mmmmm..." he moaned, nuzzling his face a bit deeper into her bosom.

Batman. snorted. His loose lips were dragging drool over the inside of her sparkling cleavage, and Harley giggled at the feeling.

“Oh Batman~” she sighed.

Harley held his head still as he began to **** and sputter from the lack of air, trying to hold back a mad cackle and just take in the moment. Her heart was beating so slowly, but so deeply powerfully as she took Batman's mind from him one last time. He started shuddering and thrashing more violently, powerful pulses running out through his shaft, and she grinned.

“Good boy…. good little boy… everything’s okay, mommy’s in control, and it’s time for you to go night-night now…”

He couldn't fight it. She was too strong, too soft. Finally, with another shuddering explosive orgasm, he drifted off into a deep sleep between her sedative breasts, defeated. He sighed the last of his air out of his lips, gave her cleavage a brief, slow, weak raspberry, and went still, hanging forward in his chains. The insane beauty felt him slump, and the airy groan of slumbering submission between her boobs. The great Batman was taking a quick snooze.

Harley finally allowed herself to laugh jovially, poking at the Batman’s sticky penis with her fingers and holding his sleeping face between her large and bare perfumed breasts.

“Batman…. you LOSE!” she shouted, pulling his lolling face tighter against her. She cackled openly and proudly, shaking him side to side against her bosom, and his limp body followed along without resistance. It was finally over. The legend of the Batman was concluded, finished... done for. Her female fists, her dainty punches, her leggy high-kicks, her incredible body, and at last her gorgeous breasts had transformed him into a sleepy, quick-shot loser.
