A Birthday Gift

"It's time for your birthday gift, of course." Calendar Man grins, "There are three to choose from, but you can only have one." He gestures over to the door and Vicki Vale pushes a cart carrying three sheet-covered boxes over to Calendar Man. "Now, let's see what's under these sheets." He pulls the first sheet unveiling a glass case holding a vial of bright pink gas, "This is Ivy's Venus concoction. It will make anyone you dose with it irresistibly aroused for quite a long time. Most here are already under its effects, but I'm sure you could find a use for it."

Calendar Man pulls the second sheet and reveals another vial, "This is a special cock-growing serum. It will give whoever is injected with it a massive cock, if you couldn't guess. You can use it on yourself or give it to someone else if you so wish."

"This third one is my personal favorite..." He pulls the sheet revealing a small device vaguely shaped like the head of a cat. "...pressing the button in the center will summon Catwoman to join you in conquering whoever you're facing in one of the rooms ahead. It is only a one-time use though so I'd make it count."

Calendar Man looks to Batgirl with anticipation, "So, what will it be?"
