The final challenge.

"Wake up, my star student. You don't have a lot of time to get ready before Daddy gets home." Your mother is trying to sound chipper, but you can hear the tension in her voice. You stretch and **** your body to lift itself out of bed.

"Ugh...why does my whole body ache?" You look around for some clothes but your dressers are empty. "What's going on here?!"

"Honey, try to relax. Yesterday's sissy pills have counteracted the stud pills from the day before. You have to take the test as you are. Naked, alone, and with only your own strength to face it." She turns away, not wanting you to see the fear in her eyes.

You want to say something to reassure her, but then you feel a fresh bout of anger rise up inside you. Why should she be afraid? You're going to win this! "I don't need anything to pass some test! I don't need you!" She stifles a sob as she rushes down stairs. You shrug, you'll show her.

You take a shower, psyching yourself up as you get ready to face your father. You take a good look at yourself in the mirror after your morning ablutions. Sure, you may still have feminine features, but the fire in your eyes is all man. You head downstairs, ready to face anything.

"So you're finally here. And I hear you've become a real alpha stud since I was gone. Then I hope you won't mind proving it." You father stands before you, larger than life. You plant your feet as firmly before him. You steady your shaking knees. You **** your neck to straighten, the strain scaring you it might snap, and look him square in the eyes. What you see in them terrifies you...merciless, abyss black cold judgement. But you have grown more familiar with terror. You **** yourself to hold his gaze.

"Hmm. I won't lie. I do see something different in you. But is it strength? Or just the stubbornness of a bratty Bitch?" The word "Bitch" echoes inside you in your dad's deep resonating base, but you tell yourself it's just a word, and you are beyond words now. You keep your eyes leveled at his, even if your neck is starting to ache from craning it up.

"Ha. Okay. Have it your way...'son'. I can't test you in most ways someone would define a man. You have no strength to test. You're small, you look like a girl, I could turn your ass into a cunt in minutes. The only test I think you could even technically pass is one of will. I'm going to stroke your cock and you're going to stroke mine. If I cum first, you win. When you cum first, you lose."

Your dad steps forward. Every muscle in your body goes taut and tense as you **** yourself not to recoil. You feel his hand wrap around your tiny cock, his fist swallowing it even as it swells and hardens in his hand. You wrap a hand almost all the way around his shaft and tell yourself you have a chance.

By the first stroke your cock is already dribbling and throbbing and on the verge of shooting off. You know this is where you are weakest, but you close your eyes, hold your breath, and decide it's where you will prove your strength...

You drool on your daddy's dick and start sliding your hand in quick, corkscrew motions up and down his shaft. You tell yourself a manly man like your daddy probably doesn't have as much practice jerking off as you do, and you put a lifetime of learning into your hurried handjob. You feel your knees weakening, feel his cock throb, feel every inch of your body beg you for release...

Something has to give...will it be him...or you?
