Like a dog sitting obediently waiting for orders from its master, Yuuki sat on her knees on the floor and stared at Arthur's cock filled with sperm.
Chiyuki's hand stroking Arthur's cock made Yuuki jealous because she could only stare at it without being able to do anything.
Chiyuki's hand caressing Arthur's cock made a lewd sound that attracted Yuuki's lust. Her body had been obedient as Arthur's Exclusive Maid had pushed her to become a disciplined woman who could control her lust.
"Master, am I not allowed to interfere in this sex?" Yuuki asked while smiling softly at Arthur, like a dog trying to beg its master, Yuuki moved her breasts to the right and left like a dog's tail wagging.
Sloooppp...
Ploooppp...
