You can't

Your hand moves like lightning down to your hard cock and grabs it, but before you can stroke it Hope's other hand shoots out and grabs your wrist.

"I knew there was nothing wrong with your cock! You're just a little sissy who likes it in the ass!" You open your eyes in surprise. Hope is standing above you, looking down at you with a wicked grin. "Admit it! Look what happened as soon as you got something in your little sluthole." She starts to finger you harder, hooking her fingers around to find your prostate. You can't help but moan agreement.

"Take your hand off your cock!" Hope orders you. "Keep them by your side!" You comply, whimpering softly. Your cock has never been this hard, and when Hope slaps it an explosion of pleasure wracks your whole body. "Please..." you whisper, "Please let me cum..." Your cock is dripping with pre-cum, and Hope gathers some on her finger and begins to slowly apply it to your throbbing prick.

"Maybe," she says. "First, tell me this. How come you can't get your cock this hard for your wife?"

You're too turned on to do anything but answer truthfully.

"Because I don't want to fuck my wife! I want her to fuck me! I want her to pound me in the ass with her big rubber cock!"

Hope laughs, and puts her precum covered finger to your lips. "Shhhh. Not so loud." You realise you just shouted. Hopefully no one in the waiting room heard you.Your face flushes red with embarrassment as Hope pushes her finger into your mouth.

"You realise your wife isn't going to just bend you over and give it to you. You're going to have to earn it like a proper slut." You nod your head quickly. "You're going to have to lick and suck her big cock, like this." Hope pushes her finger deeper into your mouth and you eagerly begin to suck on it, tasting your salty precum. "You might have to put on a show, show her how deep you can take it." She takes her finger out of your mouth and wraps her hand around your cock. "You're going to have to look up at her and beg her to fuck your ass."

"Yes, yes, I will!" you answer breathlessly.

Hope begins to stroke your cock. "What will you say?"

"Please fuck my ass! Please!" Hope slaps your cock again and you shudder with pleasure.

"Please punish my little sissyhole, you mean! Say it again!"

"Please punish my little... oh God... uhhhhhhhh..." Your eyes roll back in your head as an orgasm rips through you. Hope jams her fingers deep into your asshole and laughs as your cock sprays an impossible amount of cum into the air. It rains down on your legs and chest, staining your shirt. Your cock pulses again and again, and when it finally stops Hope scoops up a fingerful of cum and brings it to your lips.

"Drink your cum, slut."

You lick it eagerly from her fingers. You've never cum that hard, and as you look up at Hope you realise you will do anything she says.
