Cass was quite proud of the other Bats.
They never had the same start she did in life or have the same opportunities to achieve excellence. Which is all for the best because she wouldn't wish that level of isolation on anyone. But they've overcome their late start in life and really improved in leaps and bounds since she formulated their new training methodology.
Still panting harshly, she pulled her knot out of Duke's tight grip, savoring the way the rim pulsed around the length of her dick, trying to pull her back in. Duke lay limp and exhausted under her, come spilling prodigiously out of his reamed out asshole as she sat up and looked at the training room's doorway, where Tim stood nervously, hands subconsciously clasped behind him, over his pert ass.
Like that would stop her. He'd have to fight for his life if he didn't want another rough pounding today.
She offered Duke a hand and heaved him to his feet.
Legs wobbling, come sliding down the backs of his thighs and dripping on the mat, Duke thanked her and stumbled to one of the benches along the wall, where he sat down gingerly.
Stretching her arms over her head, Cass's gaze returned to Tim.
"Well? Did you come to train or are you just stopping by to say hi?" she asked, letting her arms fall and stroking her dick as it stirred again.
Of course he was here to train. He'd come naked. That was Cass's rule. Show up naked and ready to spar or don't bother her during training hours.
Taking a deep breath and stealing himself, Tim stepped forward.
He'd improved a lot. Sparring with him was getting to be more fun than ever before, and lasted much longer. But she'd caught sight of Duke shifting restlessly and getting up to leave, so it was time to end this. As humiliating and embarrassing as it was for alphas to get knotted and bred, as effective of an incentive as it was to fight harder to avoid getting pinned, the whole thing was much more effective with an audience.
Tim wouldn't be able to meet Duke's eyes for days if not weeks.
Cass tripped him up and in the end it was as simple as that. NExt moment, she had him on the mat, struggling ineffectively, her cockhead pushing past his rim, still puffy and swollen from their sparring match two days ago.
Duke stopped in his tracks as Tim cried out, turning to watch.
It was hard for an alpha to resist a good show, even if they'd just gone through the exact same humiliation themselves only half an hour ago and were still nursing their wounded pride.
Cass never bothered to draw it out.
So long as the family was going along with her training regiment, there would always be plenty more holes to breed than she really had time to savor.
Tim continued to struggle and yowl in pain as she pushed in, clawing at the mat to try to get away as she fucked him with her large cock, stretching his hole obscenely. Her knot swelling since before she'd pinned him down, it made him cry out every time she pushed it in or pulled it out, before finally thrusting all the way in and waiting for it to tie them together. Pleasure rolled in waves over her as orgasm hit.
Punching the mat in frustration, Tim ground out, "I thought I'd have you this time."
"Your footwork. Still gives you away. Meditate more," she said, letting go and laying down comfortably on top of him.
He reached back to grab her hips and pull her out, but it was too late and he only hurt himself trying. Cass propped her head up on one elbow and winked in Duke's direction, watching him jerk off.
"Come here," she called to him, and he did as asked. "Come on his face?"
Duke, his pupils blown wide, stared at her a minute, before zeroing in on Tim's aghast expression.
"Uh, you sure? I mean, I'd love to, but-"
"Don't even think about it," Tim ground out ferociously, face furiously red.
Duke swallowed, glancing at Cass again before grinning slightly and moving in.
"Actually, no need to tell me twice," he said, kneeling down and stroking himself quickly, his knot soft but his dick twitching as he pointed it down to Tim's face.
As Tim started to struggle again, she lifted herself up and put her weight into pressing his head down into the mat with one hand, pinching his left shoulder with the other to keep his arm numb and ineffective.
Duke came fast, not as copiously as he would have if he was buried to the hilt in someone, but still sending thick and pungent milky ropes of come to drip down Tim's cringing face, over his cheeks and nose and chin.
As soon as Cass let Tim's head go, he buried his face into the mat and didn't struggle or speak any further.
"What's going on?"
Cass and Duke turned to look at the entrance to the training room, where a very confused Damian stood with his hands cupped in front of him, eyeing Duke warily.
"Bonus training. Tim needed extra motivation. Duke, you can go."
"Sure thing." Looking a little happier than he usually would with his ass leaking Cass's come, Duke stood, and walked past Damian, giving him a friendly wave which Damian ignored, looking a little anxious.
"Don't worry. You're too young for extra motivation," said Cass, testing whether or not she could pull out yet. "Your turn soon. Sit."
Swallowing loudly enough for the sound to carry across the training mat, Damian nodded, and tried to find a spot on the bench that wasn't covered with come that had leaked out from Cass's previous sparring partners that day. He finally perched himself on the corner, flinching as his thigh touched a sticky puddle.
Below him, Tim was starting to sniffle, all the fight gone out of him.
He was a good, determined alpha.
He'd be an even more worthy opponent next time.

Spent and chafing a little after her second time fucking Bruce that day, Cass walked bonelessly into her room to get a nap in before patrol.
"Boys kept you busy today, huh? I was starting to really miss my girlfriend."
Steph sat perched on the edge of Cass's bed, leisurely stroking her cock with a playful glint in her eye.
"So glad to see you," Cass said, shutting the door behind her. "Need a real alpha. Boys are useless."
"That they are," said Steph and got up to kiss her, pushing her towards the bed, hands already groping Cass's rear.
It was obvious who among the two of them would win in a fight, but that's not why Cass was dating Steph. Sometimes you met an alpha with knot game so good that all your alpha instinct got overwritten and you wanted nothing more than to be pounded into the mattress until your brains turned to mush. And after a long hard day training and reaming out others, there was nothing better than getting just that.
