Suck it

"Yes, Master John." Fi's monotone voice drops into a low and seductive tone as she glides down to you, lying down on the bed with her head between your legs. You inhale sharply as she opens her mouth, lowers her head, and engulfs your entire member down her throat.
The feeling is unreal. For her metallic appearance, her mouth feels like a regular human's. Hot and wet. Her tongue sticks out and licks under your balls. Finally, she slowly draws back, freeing some of your cock from its heavenly confines. She keeps some of it in her mouth, looking up at you. Her sexiness is amplified by her exotic appearance. The odd color across her skin, her seemingly blank eyes, the diamond on her forehead, and her lack of arms all make you truly appreciate this experience.

Suddenly, you feel a tight sucking sensation. This wasn't a regular blowjob by any means of the word, but the suction is stronger than anything you felt before, driving you over the edge. Her throat has become lustful vacuum, magnifying the magnificent sensation surrounding your head as well as drawing out your eager seed. You can't hold on, and groan loudly as you give in to the aggressive twitching in your cock. Your first shot fired off, eliciting no reaction from your perfect servant. If anything, her unreal suction steals your sperm, rather than you shooting it into her. It's too much, your shaft is overstimulated and you emit a primal roar.
Fi finally ends the blowjob, slowly removing your cock from her other-worldly mouth. You're completely softened now; your heart beating so hard you thought it would break out of your chest. With a familiar chime, she shrinks into a small orb of light and retreats into your sword.
Feeling blood pump through every vein in your body, you take the time to accept this blissful experience as a once-in-a-lifetime blessing. As your heartbeat returns to a normal rythm, you feel yourself dissolving into a deep sleep.
