You gulp down eagerly.

As you slurp and lick at the wonderful tasting rod of meat several thoughts roll around in your head. This is an amazing magical diet. All you have to do is stop sucking and you won't become a girl at all, assuming he is telling the truth, and looking at yourself in the mirror you can see he clearly is. You would guess you are 140 to 160 lbs at the most. 'So I'll just stop.' You form the thought in your head as you dip your head down and take his balls into your mouth while stroking his rock hard meat. The feeling of your hips widening slowly, and your breasts growing between your arms is down right odd, but the strangest by far is the feeling of crawling critters as your hair becomes fuller and fuller on your head. Returning your mouth to his cock, you dip your now slender arms down your body, pausing a moment on your now a bit larger breasts, definitely at least a B cup now, down your tight sexy abs, and take your swelling cock into your hand. It feels so wrong feeling it's hard length as you bob forward slurping his massive member down your throat. 'No time for that, I have to stop sucking his cock.' Once again your form a thought in your mind, but once again your body does the opposite. Reaching up you slip two fingers up his asshole, his body tenses as you bob back and forth faster and faster allowing him to fuck your face. You can hear him moaning, and he takes your head in his hands, gripping your hair in his fingers. He pulls you in time with your bobbing and you work your slender fingers deeper and deeper into him.

“Wait, oh god I am going to blow, that is just to much.” He yells out, and it isn't much of a warning as he starts spraying cum down your throat while the word much exits his lips. “Oh you would be so much hotter if you took it slow.” He says finally as his body spasms and the last few drops stop flowing. “I was really looking forward to fucking you, but look what you did, I am so soft. No one has ever gotten me off so completely with just their mouth. What a slut.” Looking down he sees you are still suckling his soft meat, your lips still around the base of his cock. “What the hell?” He pushes your head back causing his member to slowly slide out of your throat till the head finally slips from your mouth with a little pop, a trailing string of spittle connecting you to it for a few moments more. Hungrily you lean up as he pushes you back, not wanting to let his cock go. “That has never happened before? Why are you so obsessed with my cock? Do you know what you are doing?”

Licking your lips you look up at him smiling. “Ya, I have a plan. I am going to suck just a little bit so I get all slim and sexy, then stop so I just use you as a magic diet plan and don't even turn into a girl at all. Then I can just wear any costume and go to the party as a sexy man, so there.” Pleased with yourself you slap him on the leg as you finish speaking.

“You do realize you just sucked me off, drank my cum, and turned into a girl right?”

“No I didn't, you aren't even hard yet.” You reply taking his flaccid meat into your hands trying to coax it back to life.

“The spell only works once you silly slut. What the hell are you doing I only cast the spell to turn you into a girl, I didn't use any mind control.” He looks down at you as you take his cock into your sexy black covered lips, your makeup a bit smeared by the previous attention and can't help but give in. “Fine you crazy slut, suck away.”

“If that is what it takes.” You say and greedily devour his cock. Bobbing down on him and stroking and massaging his balls it takes a little while before you can get him hard again, but you are determined to finish the task. His cock fills you as it gets harder, stretching your throat. Using your hands to work the shaft as you suck and lick all over till his cock is once again rock hard and glistening with your saliva. It just feels so right sucking and lapping at his cock, as if you had been missing out all your life. You drink it down, making sure to push till your lips touch the base as many times as you can, making him fuck your mouth like an eager pussy.

Breathing heavy he says, “You know, now you are a girl I could just fuck you. I think if you like sucking cock, you would love that.”
