She uses a sonic device

Vallery's world started to go black as she felt every thrust of Jack's cock inside her. He continue to thrust into her deeper and deeper. She starting to lose all hope when she saw it.

It was a small metallic sphere, a tool that must of fallen out of her suit when she was fighting in the rumble.

She reached for it as Jack tried to hold her back as his grip around her neck got tighter, "Not this time super girl you aren't getting away."

Vallery pulled her arm out harder at the device, "I can not lose...."

She grabbed hold of the device, "To a man!" She pushed a button on top of the ball making the device open up making a screeching noise that only the men could hear.

Jack let go of Vallery and screamed as he held ears in pain.

Vallery turn around breathing heavily as her huge breasts went up and down in sweat.

Jack felt strange, he felt like he needed sex that he needed to cum now.

"What....what did you do to me bitch! Ahh!"

Vallery replied, "This a sonic device human. We use it on my planet on men who tried to attack women. It something similar to pepper spray."

"What does it do? Shit! I feel...I feel like..."

"Like you are ready to explode?"

"Yes!"

"It over stimulates the male sex drive in their brain which is more primitive then a female's brain."

"That's great! What does it do?"

"It makes you cum at the slightest touch?

"What!"

"It means I win! Give up now and I will give you my body which will be the greatest pleasure you will enjoy."

"Why...why would you do that?"

"Because you fuck well warrior. You deserve to to end well in this fight. There is no shame in losing this battle. You are as they say, 'out of your league."

"I see and if I refuse?"

"Then I will fuck you like the coward that you are as you repent all your sins."

Jack clearly in pain as sweat came down with his cock getting more aroused by the minute said, "Let me think about that for a minute."
