After awhile the party adjourned onto the deck, and not too long after Monica and Courtney realized they had made a mistake. The sun was blazing and it was just too hot for their costumes; they were both pouring sweat under their leather.
Monica explained the situation to Carla and asked if there was anything they could change into. Carla said sure and pointed them inside. As she followed them, enjoying the way they moved in their form-fitting outfits, she realized that this was an opportunity to fulfill a fantasy; some of her favorite videos featured superheroines in bondage. In a split second her mind was off and racing, all other considerations forgotten.
"Wait here," she said abruptly, and strode quickly back onto the deck. She returned a moment later leading Annabel by the arm, and the two of them swept by and up the stairs.
As they walked Carla explained to Annabel what she had in mind, and after a couple minutes they returned with hands full of equipment. Monica and Courtney were facing away from them, toward the window, and didn't hear a thing as Carla and Annabel crept up behind them. Suddenly they felt their hands being pulled behind their backs and cuffed.
As they turned around comprehension dawned in their eyes, and since they weren't necessarily opposed to the idea, neither of them put up much of a struggle. But as Carla fastened a ball gag across Monica's mouth, Courtney whined, "Why would Wonder Woman be capturing Batgirl? Aren't they both good guys?"
Carla sighed. "Maybe's she's been naughty. Catwoman was always a bad influence on her, you know." Remembering that she was in charge here, Carla snapped, "You ask too many questions," and silenced Courtney with a gag of her own.
Annabel and Carla led the two bound girls to the bedroom, where Carla bent them both onto the bed, faces on the comforter and asses in the air. She took a minute to savor the view -- leather stretched tight across two shapely rumps -- knowing that these two beautiful supergirls were hers for the taking. The feeling never got old.
