Demi gets to work

After Jamie leaves, Demi strips down and gets on top of you. She starts riding your dick. You've healed up pretty well and haven't had sex in a while. Her pussy feels amazing and you cum in no time. Demi gets off of you.

"I said I'd fuck if you even if you only had one ball left and I kept my word," she says as she puts a ball gag in your mouth, "Now you owe me."

Demi grabs your balls and roughly inspects both of them.

She starts to caress your right nut and says, "This one looked so bad the last time I saw it. Sorry I couldn't do more to save it."

You give Demi an odd look. You don't know what she's talking about.

"You don't have to be embarrassed. Jamie told me Kate popped your right ball. If it makes you feel better, I wouldn't have even noticed it was fake. It feels so real."

Demi then punches your right testicle with a ton of force. You bite into the gag hard and pull on the restraints. Demi doesn't notice as she punches your left nut.

"They both feel the same. Jamie told me you got a top rate prosthetic ball."

Demi then fires her first into your very real right testicle 3 more times.

"It feels so good to not have to hold back!"

Demi slams her knee down into your right nut. Her whole body is pressing on it. You're in absolute agony and would do anything to make it stop.

Demi grinds it for a few seconds before getting off.

"I told Jamie I wouldn't ruin the fake one. I bet it was expensive."

You're happy to know she's done when she grabs your left nut and squeezes it. Your balls are throbbing in pain. She punches your ball but you can feel that she is going easier on this one. You're still in a ton of pain though.

Demi turns around and sits on your boner. She then proceeds to bounce her ass on your cock. Her large cheeks clapping on it isn't something you've experienced before. After a few minutes she stops.

"That should be enough of a break for your balls."

She turns around and looks at your sack. Your right nut is swollen and discolored. Your left one is in pain but it isn't as obvious.

"Oh my God! I thought the right one was fake!"

She grabs both and re-examines them.

"I must have misunderstood Jamie. Your left testicle is definitely fake. I'm sure of it."

She drills her fist into what she thinks is the fake one. Your eyes fill with tears as she punches you again and again.

"This is so durable," she says between punches, "I can feel it flattening."

She smashes her knee on both of your nuts and notices you struggle in pain.

"Oops. Did I crush the good one too?"

She shifts all her weight onto the left ball and she sees that your still in pain.

"No. This one can't be real too, can it?"

You frantically nod your head yes.

"Oh my God," she gasps as she covers her mouth in shock. She's still on your balls.

Demi takes off your gag and you immediately say in a weak voice, "You're still on my balls!"

She hops off then grabs your bruised gonads. You shriek in pain.

"I don't think I broke them, but they do not look good."

You're just gasping for air.

"I swear, Jamie told me one popped," Demi says.

"I believe you."

Demi places ice on your balls and starts to release you.

"Why do you even stay with her?" She asks, "Is it worth it?"

"I didn't think we were getting back together this time. It just kinda happened," you reply as Demi finishes releasing you.

"That doesn't answer my question," Demi says as she starts to put her clothes back on, "But if you ever decide that it is enough, let me know."

Demi leans in and kisses you on the lips. You start to make out. You grab her ass but she pulls your hand off.

"Not until you've broken up with Jamie."

And with that, she leaves with you staring at her ass the whole time.
