Barbara cried out in surprise as she felt teeth on her labia. Kara had bit her! It was as if she was prodding her to do more than just tease. (Fine then), Barbara thought. With her middle fingers, Barbara lightly touched Kara's puffy lips and opened her up. Smoothly, she moved her tongue up and down Kara's wet slit, tasting her honey. She licked her friend over and over again, only stopping once in a while to make sure that clit didn't lack attention. She gyrating her hips, smothering Kara's face as the blonde moaned into her cunt. Barbara dipped a finger into Kara's warm tunnel, to be pleasantly surprised at how tightly her muscles clenched onto it. Barbara's best friend was her sexual plaything, and she loved it. Their friendship may not be the same again, but Barbara didn't care, as this... this was better. She regretted that she had never taken the initiative before, even after all those times she caught Kara staring at her in the showers after mission. She was so focused on making her friend squirm that she didn't even see Dick approaching until his half-erect member was directly in her face. Nor did she notice that Kori had crawled onto the bed behind her, and had inserted a finger into her Barbara's ass.
"Kori thinks you'll come before Kara does," Dick said, with a smirk. "If she wins, the girls get to dominate you for a day, while I have to watch. If we win, you get to have Kori at your whim."
Dick didn't have to speak another word. Immediately, Barbara's mouth went to Dick's rod, and she wrapped her lips around his shaft as one hand gripped his base. Her other hand remained on Kara, one finger stroking her canal while her thumb massaged her clit. Barbara bobbed her head up and down, taking in Dick's length. She needed to get him hard, and she liked to think she was getting good at it. Dick always had a soft spot for her, even if he was with Kori. When he was hard and ready, Dick pulled out. A brief pang of jealousy washed over Barbara, as part of her wanted him to cum in her mouth. But they had a contest to win, and Dick's wonderful penis was to go into Supergirl tonight, not Batgirl.
Barbara pulled Kara's thighs up higher, giving Dick better access. She watched enviously as Dick inserted his tip into Kara's wet hole. He gave her a few more short strokes, gauging her tightness, before plunging the length of his wonderful fleshy machine into the depths of Barbara's best friend, who responded with muffled cries into Barbara's cunt. Barbara had always suspected that Kara had a crush on Dick. If that was true, the lucky girl was getting to fulfill two lustful fantasies in one night, then. Dick pulled out and slammed into her again, evoking a loud grunt. Slowly, he worked his way into a rhythm, giving the blonde Kryptonite the best fucking of her young life.
Meanwhile, Barbara had to concentrate on Kara's engorged clit as Dick pistoned in and out of the blonde beauty. Barbara couldn't let herself get distracted by Kori's magical fingers, as one finger stroked in the inside of her anal passage and two others rubbed her clit in a circular motion. Kara, under Kori's direction probably, seemed to find focus, swirling her tongue deep between Barbara's folds. It was all too much. Kori's fingers, Kara's tongue, and the seeing her crush pound away at her best friend was too much for Barbara to handle. Her body trembled and quaked in anticipation of what was coming. Her toes curled and her legs went stiff as her orgasm hit her, setting her body on fire. She felt herself squirt onto her best friend's face.
"Oh god," she cried out, her body spasming too much to focus on her objective.
It was too late, but Kara was not far behind. With Barbara out of commission, Dick took the initiative. He raised Kara's legs, placing them on his shoulders and increased his speed, fucking her until she reached her own screaming orgasm. Shortly after, Dick thrusted into her one last time, and held. Barbara watched his body twitch, as he ejaculated inside of her. As he pulled out, Barbara dove her head back between Kara's legs, licking up the warm seed that was spilling out of her. She may have lost the contest to Supergirl, but Batgirl wasn't going to miss out on the spoils...
(Note: I'll take suggestions as to what the girls get to do to Babs)
