You wake up unchanged. Initially you feel a little disappointed, but then you realise it means that you get to experience being turned into someone's dick. You get up and, after taking a pee, you jump in the shower. Ten minutes later, you get out, and are surprised to find Rob, your dad's best friend stood in front of the closed bathroom door.
He looks at you with a sly grin and then says;
"Hi there, I bet it's a surprise to see me, isn't it?"
"Err, yeah", you reply. "It is kinda. What're you doing in my bathroom?"
The grin turns into a smile and Rob replies;
"Well, you're dad lost quite a bit of money to me at poker last night. But rather than pay it back, we decided that he could repay that debt by allowing me to turn you into my penis, for twenty four hours, whenever I want, for the rest of the year. Today is the first day of you paying off your dad's debt".
You feel a sudden rush of excitement, combined with a little fear and apprehension. You decide not to appear too willing though.
"Wait, why me?" You ask. "It's dad's debt, not mine. That's not fair".
Rob chuckles as he says;
"Well, as you know, our two families are sorcerers. And sorcerers don't do that kind of thing to other sorcerers without consent. Unfortunately for you, apart from your immortality, you're not one of us. That means you're fair game. I mean seventeen is a little young, but the debt needs paying. You can try to resist if you want, but it won't do you any good. I AM going to be leaving here with you as my cock".
You slowly nod your head but say nothing.
"Good", Rob says cheerfully. "Don't worry, it won't hurt".
Before you can respond, you feel an odd tingling throughout your body and your vision suddenly blurs. You also feel a rush of cold air that appears to come up from the floor. It only lasts about three or seconds, and then the tingling, blurred vision and rush air disappear. You feel dizzy for a few more seconds, but when it eventually fades, you're amazed to find that you've shrunk. You're not entirely sure, but you estimate that you're now about ten inches tall.
You temporarily forget about Rob as you look around in amazement at the now giant world you find yourself in. Your sink is at least as tall as a five or six floor apartment block. The toilet looks to be about three stories tall. It's only when you hear movement that you remember Rob is there with you. You turn back to find that he's unfastened his jeans and pull them, and his shorts, down to his mid thighs. He's stroking his dick, which quickly grows to what you think is about nine inches in length. He then crouches down, and you feel a sudden sense of fear as he reaches for you with his enormous right hand and wraps his fingers around your torso.
He lifts you off the floor as he stands up again. Holding you in front of his giant cock, which he's holding in his left hand. You watch in amazement as his urethra flares open like a vertical mouth, only without teeth. Your heart is pounding hard in your chest as your fear grows. You're suddenly having second thoughts, but you don't have the stone with you, so you're helpless. He turns you until your face down with your feet pointing towards his cock.
He groans softly as he slowly slides you down the long tunnel of his urethra. It feels soft, tight and warm as your feet and lower legs slip inside him, followed by upper legs, waist and your hands, which are by your side. At that point, you feel his urethra contract around you, and then there's a sort of gulping sensation as Rob's cock sucks in your entire torso. At that point, your body is now trapped inside the entire length of Rob's nine inch long cock. Rob then turns around and faces the full length mirror on the back of your bathroom door.
You can only stare helplessly into the mirror as you see that only your head is left outside of him. The end of Rob's urethra is gently pressed around your neck, like a pair of lips sucking on a cigar. You feel a shaking as Rob chuckles, and then you feel the tingling sensation again. This time though, instead of shrinking, you feel your feet and ankles melt as they merge into Rob's cock, and then the sensation slowly travels up your lower legs. About thirty seconds later, you feel your upper legs and waist melting. At that point, you realise that you can feel part of Rob's palm and his little and next finger on the front of your legs, which are now the underside of Rob's dick. Over the next minute, you feel your entire torso and neck merging with Rob's body as you turn into his cock. You can now feel his whole hand cradling your body.
Only your head is left now. You look up in the mirror and see Rob smiling with his eyes closed, obviously enjoying making you a part of him. The tingling moves up into your scalp and you watch in surprise as your hair disappears, leaving you completely bald. You notice a ripple in Rob's pubic area, and realise that the hair that had been on your head is now his neatly trimmed pubic hair. Next, the tingling moves in to the rest of your head and face and you can only watch as it takes on the shape and color of his cock head. Your eyes, nose and ears all disappear, but you're surprised that you can still see and hear. Your mouth slowly turns until it's vertical, and your lips become the outer part of Rob's urethra. Finally, you feel your throat stretch all the way down what used to be your body, obviously turning into the rest of his urethra. And then the tingling fades away.
And that's it. No trace of your body is left now. All you can see as you look into the mirror, is Rob's penis. Despite what you see, your brain is having a hard time accepting it. The fact is though, your wish has come true, you're now the penis of your dad's best friend. You can't help feeling afraid as you stare at your new body. And being completely paralysed is not pleasant, but you still feel an odd sense of exhilaration about being part of another person's body.
You watch yourself 'deflate' as you feel yourself becoming flaccid. At that point, Rob lets out a satisfied sigh as he slowly opens his eyes. Once you're fully flaccid, you feel another shaking as Rob laughs.
"Wow", he says, elatedly. "I REALLY enjoyed that. You feel great down there. In fact, in all honesty, I'd be happy to let you stay like that forever".
He then lets you drop, and you hear a loud slap as you hit his left thigh.
"Well", he says. "I'd love to stand here and chat. But I got things to do. I'll turn you back to normal tomorrow morning. Until then, enjoy being my cock. Oh, and this will be the norm every three or four days for the next year, so you need to get used to it. Who knows, by the time you've paid off your dad's debt, you might decide that you'd like a new life as my penis".
With that, Rob pulls up his shorts and jeans, leaving you in darkness and pressed against the inside of his left thigh. He then fastens the button and it gets a little tighter as he pulls up the zip.
