"Alright. You have to lift the weights up. I set it at the highest in possible, and we're going to do five sets, with ten reps each. Not to mention, if you stop in between, I will mercilessly spank your ass until you keep going and finish the set." He says, moving her hands so she's gripping two rods at the sides of the seat for support.
Eventually, thanks to her butt continuosly rubbing on his cocks, he gets hard, and immediately slides both cocks into her ass with a slight moan.
Suddenly, she feels the weights get heavier right before she manages to complete the set. Looking over would reveal Squeaky sitting on the weights with a serene smile on her face, and adding another twenty or thirty KGs to the load!
"Well, what did you expect? That we'd be nice and caring, to let you rest and stuff? Hell no." Jackal says, laughing before he gives her a poke to the butt after two minutes. "Next set. Go!"
She can barely manage to get past the seventh one before her legs give out. As promised, the spanks come down on her ass, loud swats ringing out across the gym as Jackal pushes her to go harder.
Once she moves, the spanks immediately stop, and after she finishes the set, Jackal pats her back. "Good girl." He says, chuckling as he slowly grinds in and out of her ass. "Take five. Two was a little too short." He says.
Again, she stops, this time at the fifth one, and again Jackal mercilessly spanks her ass until she pushes through the set.
"Wow. You should see the view from back here. Nice and red." He says, laughing as he holds her hips and keeps fucking her butt slowly.
He grunts in pain, and is quiet for a second. "Well, that fucking settles it. Push through the rest of them, you ass." He growls, his claws digging into her hips as he starts fucking her butt hard and fast.
"Oi. What are you stopping for? One more set left! Keep going!" He growls, fucking her ass even faster now, before spanking it hard. "No rest! Finish it! Go!"
"Another accident, and I'm going to tie you up and fuck your ass till you can't move!" He grunts, grabbing her breasts as he continues fucking her ass.
"Whew. Well... There we go..." He groans, slumping back in the chair. "Bloody... Ow... Squeaky, can you please finish Phorsaal off?" Jackal grumbles, and Squeaky flutters over before perching right on top of her dick. "Which hole do you want to rape?" She asks with a giggle.
She lets out a loud squeak, her eyes going wide as her ass is suddenly speared open on giant horsecock. She immediately squeezes tight, and wraps her arms around her neck, nodding to let her know she can start fucking her.
