With thought, came action (18+)

"Let me pay you back for your generosity, master. This slave is yours to use."

Duncan felt his blood throbbing in his ears.

Leia's sudden action had completely taken him by surprise. He never expected her to offer herself like this. Hell, he didn't even think about asking her to pay back like this.

The moment she whispered those words, Duncan felt his cock throb with purpose. His libido which he had been controlling so far was like a rampaging monster at this moment. He could feel a heady rush all over his body.

Still, a part of his sanity prevailed. 

"Leia, you don't need to do this."

He bit out his last struggle.

If anything, this seemed to only further motivate her. The body that had been pressing into his was now grinding on him. Duncan could only barely restrain himself from devouring her at this moment.

"Leia is not here, master. The only one here is your slave. You can use her like you want."

That did it!
