Punishment
"First things first," Black Canary said, eyeing the six girls cruelly, "M'gann, take off. I don't want anyone interrupting your punishment."
M'gann obeyed, taking off and putting the Bio Ship in an orbit around Earth. "Secondly, have shackles drop from the ceiling."
M'gann obeyed, telepathically creating six pairs of shackles from the ceiling, which Canary used to chain up each of the girls. "Good," she purred, "now, Zatanna, give me a paddle."
Zatanna gulped, but obeyed, magically summoning a large paddle for Black Canary. "Now for your punishment." Canary turned on Barbara first, bringing the paddle down on her ass. Barbara squealed from both pain and pleasure as Canary kept spanking her as hard as she could. "You like being punished, don't you, bitch?"
"Yes, mistress!" Barbara moaned. "Punish me more!"
"You've been naughty, haven't you, bitch?"
"Yes, mistress! I've been so bad!"
Canary kept spanking Barbara until her ass was nice and red. "Your turn, bitch." She said to Karen, smacking her ass with the paddle now. "Take your punishment and like it!"
"Aah!" Karen moaned. "Yes, mistress! Spank me harder!"
Once Karen had had her fair share of punishment, Canary moved on to Artemis, then Zatanna, then Cassie, until she reached M'gann. "Ah, the ringleader of the group." Canary purred. "I've got something special in mind for you. Let everyone else down." M'gann obeyed and retracted everyone else's shackles. "Everyone is going to take a turn punishing M'gann. Don't hold back."
M'gann smiled. She was hoping Canary would try this. "Girls, now!"
The other five girls grabbed Canary, pinning her to the ground. "What the hell are you doing?" She grunted. "I'm the mistress! You do what I say!"
M'gann grabbed the paddle from the floor and telekinetically ripped off Canary's clothes. "I think you misunderstand." M'gann purred. "You never were the mistress. We're the ones in control now, bitch."
She summoned a new pair of chains, binding Canary to the floor with her ass in the air. "Girls, show her how we punish bitches in the club."
Each of the girls took a turn punishing Canary, each using their powers to their advantage. Cassie's super-strength spanking made Canary's ass nice and red, Karen stung her ass for as long as she could, Artemis and Barbara borrowed paddles from Zatanna, and Zatanna magically summoned an array of different toys to use on her.
Finally, it was M'gann's turn. She morphed an extra pair of arms to use, spanking Canary with four paddles at once. "Who's the bitch now, Canary?"
"I am!" Canary moaned. "Punish me more, mistress! I deserve all of it! I've been so bad!"
After what seemed like an eternity for Canary, the punishment ended. "You've been a good bitch," M'gann's said, "so here's a reward."
She grew an enormous cock and shoved it deep in Canary's ass. "Aah! Mistress, my ass is still sensitive! Please be gentle."
M'gann's slapped Canary's ass again. "You'll take your reward and like it, bitch!" She exclaimed forcefully, pounding her ass even rougher. "Fuck, your ass is tight! I'm gonna cum!" M'gann's pulled out and squirted a huge load of cum in Canary's face. "Why don't the rest of you have a turn?" She said to the other girls.
They each took a turn giving Canary a reward, fucking her in the ass and cumming in her face. Eventually, they were all done, leaving Canary sore and dripping in cum.
"Okay, you girls have had your fun," Canary said, "now why don't you let me go?"
The girls all exchanged a look. "Actually," M'gann said mischievously, "how about we turn this ship around back to the Watchtower so the whole League can see how we made you our bitch?"
Canary gritted her teeth. As they flew back to the Watchtower for more humiliation, Canary silently swore that she would get them all back for this someday.
Someday soon
