It's his cock

"Tada!" John says as moves his hands away from his lap like he completed a magic trick. A massive half hard cock flops lazily onto his thigh, making a light slap as it hits. It's already one of the biggest cocks you've ever seen and it's not even fully hard yet. You wince, knowing what's about to happen to you. You put on your best fake smile.

"oh, thaaaanks," you manage, trying not to sound sarcastic but failing. He picks up the monster cock by the base and wags the flopping head at you excitedly.

"Yeah! And you should see the size of the doses! You'll be up 10 points tomorrow!" You grimace again attempting to leave your fake smile intact. Your father pushes you lightly from behind. Is this why he brought you here?

"Don't be scared pumpkin, he's not that much bigger than me, and you handle me just fine" he says, nudging you again.

Your father's pretty big you think, reluctantly walking over and kneeling between John's legs, but he's nowhere near THIS size and you can barely handle him! You decide not to mention it.

You open your mouth to the limit of your jaw and **** the still spongy head into your mouth. Your brow furrows with worry. He's not even fully hard yet? With the head now through the shaft was slightly more manageable. You begin a bobbing as much as you can on the few inches you can move in and out of your mouth.

He quickly gains full hardness as the two men discuss how cute you look getting warmed up. Your jaw aches as you try to keep your teeth from rubbing his shaft.

"Don't be shy sweetie," you father coos, firmly putting his hand on the back of your head, "show him what you can do."

He begins shoving your head harder and harder as the head of the monster cock meets resistance from the back of your throat. John wraps his hands around your head and begins to help. They both start cheering you on.

"You can do it! Go! Go! Gooooooo...UGH"

The entrance to your throat finally gives way and they cheer for you like you just scored a goal. Your eyes and throat both bulge out cartoonishly as the next several inches work their way down.

"See? Told ya she could do it! Just like we do it home," your father proudly beams, "not even a gag!"

The three hands continue to press firmly as your insides slowly stretch to accommodate the girth. You look down at the couple remaining inches in disbelief that you don't have the whole thing yet.

They let out another cheer as your nose comes to a rest on his pelvis. Your father releases the back of your head and you begin desperately trying to pull back. John lets you dislodge several inches before pulling down hard and jamming them back in, using your struggling against you.

"Look at her go! She's really good at this!" John comments as he repeats this process several times. "A real natural!"

"Ha! You should see her take anal!" Your father jokes. John smiles wickedly. "Give 'er a try! Fit's me easy!"

Holy shit, thanks dad, you think. You begin running numbers on which even seemed worse at the moment.

"Come on Kev, it's your daughters medicine," John chides, bringing his dick to a rest at the hilt and looking at you in the eyes, "What'll it be? One tap for throat, two taps for anal."

They look down at you expectantly.
