Leg Curls

"Okay, now I'm gonna make you run through the machines so you know how to use them with me, okay baby?" Kaitlyn said as she wrapped her left arm around John and her right hand around little John. She gently stroked him and led him through the gym. The couple arrived at the first machine and Kaitlyn sat John down. It was a leg curl machine.

"This is a partner leg curl machine! You can do a slightly different partner leg curl without a machine, but we'd need a third person," Kaitlyn explained, as she positioned John's legs between the soft pads of the machine's lever, "Basically, all you have to do is curl your legs down!"

John nodded and began a rep, but Kaitlyn grabbed his penis and tutted.

"You're forgetting the partner part." Kaitlyn said as she pulled off her volleyball shorts and sports bra. Kaitlyn smiled as she climbed up into John's lap, his cock sliding perfectly into her ass. He gasped in pleasure as Kaitlyn lowered herself all the way.

"What's the matter, sugar? Never done anal with an ass like mine?" Kaitlyn giggled, wiggling in his lap. John twitched inside of her.

"Cmon baby. Start going. 25 reps, every time you come, we're doing push-ups." Kaitlyn ordered. John steeled himself. He pushed his legs down, but the extension in his hips pushed him deeper into Kaitlyn's asshole. John came.

"Oh this gonna be fun." Kaitlyn said. In and out, John kept going, thrusting harder and faster.

"Oh yeah babe. That's five." Kaitlyn said, clearly enjoying herself. John rapidly burst out another 10 before she squeezed another ejaculation into herself. John moaned.

"Just ten more. You can do it!" Kaitlyn smiled at him.
