Sophia deepens her control

You run your tongue up the entire length of Sophia's slit, tasting her pussy. The flavour mixes with the residual taste of your cum, and you swallow instinctively, feeling pleasure. Sophia taps idly at your phone.

You become aware of your dick hardening again. The phantom bonds have been removed, and your arousal is building as though you hadn't just cum minutes ago. As you eat your friend out, she moans softly. "It's okay, you can touch it..." Not wanting to miss an opportunity, you reach your hand down and start stroking your dick. As soon as your fingers make contact, you flinch. Your cock feels sensitive; way more than you've felt before. Blaming the implant, you touch gingerly, finding a soft rhythm that makes your pleasure build.

"Mmmm, good boy..." She moans. Your dick twitches forcefully in your hand, and you moan. "You are a good boy, aren't you?" Again, your cock pulses. "Fuck, you're so good at being obedient. It must really turn you on..." Your mind tries to think its way back to clarity, but with the pleasure in your dick, your thoughts are hazy again. "Mmn, feel how hard you are? Is the taste of my pussy making you hard? Do you get off on serving me? On serving my pussy?" You moan "Yes..." into your friend's cunt lips. "Yes Mistress," she corrects you. Another twinge in your dick. You pull your face away just long enough to say "Yes Mistress," and resume your ministrations. "Good boy. Jerk yourself harder."

You do, and grip your dick with ****. The sensitivity almost brings you over the edge, but you keep stroking your cock. As you do, dick twitching involuntarily, Sophia keeps talking. "Remember that feeling from earlier? How good it felt to obey me? How good it feels right now? This is where you belong. That's why you feel so good, that's why you're so warm and happy right now." You don't really register what she says, but moan in agreement. Another dick pulse. "How about you give in fully? Just enjoy the pleasure of listening to me? I'm already using your little toy here to make your dick feel so good, don't you trust me? That's the reason my pussy juice is turning you on so much, that's the reason your hand feels so good... I'm doing that for you, because you're such a good boy."

At these last words, you feel your orgasm approach, but somehow it's... not... happening? You moan in frustration, jerking your dick with all of your might, but to no avail. Unable to form sentences, you let out a questioning whimper. "Well if you're a good boy, you do what you're told, right?"

"Yes Mistress!"

"Well I haven't told you to cum yet, so why would you cum?"

"Please let me cum, Mistress!"

"Not until I do, baby..."

She leans back, tilting her hips up as you desperately delve your tongue into her folds, trying to bring her to orgasm.
