She want's an ass like Gwyneth's

"I'll be honest," Jennifer said "I can't stand that Gwen has a better a butt than me now."

John laughed, "Well I can certainly help with that. Come here and let me see it."

Jennifer walked over to John and turned around. He grabbed a handful of her buttocks. Her ass was still very firm and tight, but not quite as perfect as you made Gwyneth's. "I see what you mean." He said, "You could definitely use a workout. I just don't know if you'll be able to take the rigorous workout I put Gwyneth through."

"Of course I can!" She said, offended at the accusation.

John smacked her ass as hard as he could, causing her to take a small step forward. She bit her lip to stop from making a noise. "How did that feel?" He asked.

"Fine." She said, trying to keep her voice from breaking.

"Okay, I'll give you the workout, but if you don't get the same results, it's your fault." He told her before pushing her down into position on her hands and knees. "Close your eyes." He demanded. And she listened. He smacked her ass again in the same place, causing her to let out a little whimper. "Are you sure you can take it?" He asked again.

"Yes! I can take it!" She shouted back.

John grabbed both her ass cheeks, pulled them apart and shoved his dick into her asshole, taking her completely by surprise. She screamed a little. "Can you take it!?" He asked again.

"Yes! Yes! I can take it!" She replied once again, trying to subdue the pain. She wasn't as tight as Gwyneth but John was definitely going harder on her to start with.

"Gwen didn't complain once! In fact she loved it!" John shouted at Jen as he started fucking her.

"I love it too!" Jen lied.

John spanked her hard as he buried his cock in her, causing her to moan and whimper. "Gwen worked a lot harder than this without complaining." He told her.

"I can take it harder! Give it to me harder!" She moaned. John grabbed her pony tail and jerked her head back as he thrust into Jennifer's ass at least twice as hard as he fucked Gwen. "Yes! I can take it!" She shouted.

John felt ready to cum.
