Mating Press, but she does notice something.

Swiftly, while still deep in her, Gentaro walked Kushina to the massive bed before repositioning her on her back. This had to be the softest bed she had every been on, before she could think past that her feet were in the air while he started to pound away again. The slapping noises kept going and she kept moaning only able to look at his handsome face taking in all that he is. It was in that brief moment her gaze was drawn to the anklet that was glowing a bright red that pulses with her heartbeat.

"Wh-what is- why is tha?- OH!!" Kushina tried to ask in between the thrusts. Gentaro smirks slightly, "Ah yes, I was wondering when you would notice." As he continued his pounding he began to explain. "The anklet is capable of many things, what it's doing now is affecting your nerves to seek out pleasure and getting rewarded for it." He emphasized this be pinching one of Kushina's nipples sending a pleasurable rush through her. "This of course is hitting your brain as well, with each orgasm it will imprint how I feel to you and overwriting anything you might have had with that blonde RAT! Leaving you with what should always have been mine." He smiles gently despite the fury in his voice. "Love and devotion to me and to your fellow harem sisters."

This revelation brings her to another toe curling mind blanking release as Kushina's pussy tries to milk his dick for all its worth. She feels his release too as more of his cum is added inside her and overflows out.
