The batcave waterfall parted to admit the Batgirl’s batcycle, Bruce at the controls, while the Boy Wonder held onto his waist from behind. The bike bounced and rattled as it moved from the unworked rock of the tunnel to the metal walkway of the cave, and “Batgirl”’s juicy silicone cheeks trembled like jelly. Robin took a shuddering inhalation, blushing deep crimson.
Bruce brought the bike to a stop on its podium and swung a lithe leg over, his stiletto heels clicking as he dismounted. Alfred was there with a towel waiting, and Batman dabbed at the perspiration and waterfall spray dribbling down into the valley of his fake cleavage.
“Ready to hit the showers, Robin?” Bruce asked.
“I, uh, think I’ll sit here a little longer,” Robin mumbled, his hands holding his utility belt down over his throbbing erection. The tights and green underwear of his uniform hid nothing.
“Suit yourself.” Batman sighed. “Another night with barely a real fight. It’s as though the criminals are just lying down at my feet. We’ll spar once I’m cleaned. I’ve some pent up energy I need to let out.”
Robin gulped. Like everything else, Batman had applied himself to the role of Batgirl with 120% focus. As a master of disguise and genius-level intellect, he made a better woman than a woman did. His speech, his posture, the seductive waggle of his fat ass within Barbara’s suit as he strutted towards the showers - Robin shook himself - they were all perfect.
While he had mastered a female combat style from prior experience, the issue was that his frame of reference was skewed. Far more than he’d watched Barbara fight, he’d fought against Catwoman and Poison Ivy, women who wielded their sexuality like a weapon. Bruce had subconsciously internalised every wily manoeuvre of theirs, unknowingly seducing men even as he fought them.
The last time they’d sparred, ‘Batgirl’ had simply floored him and sat on his face, full force, until his exquisite meaty buttocks knocked him out. And somehow the World's Greatest Detective was oblivious to the effect he had, even after Robin nutted several times in his armor.
With a heavy heart, Robin trudged towards the sparring hall.
