Your new tits wrapped around his prick

Your hands move to your massively swollen titflesh and rub over your huge, sensitive nipples. If Frankenstein wanted these, maybe he will want to play with them too. Forcing a saucy smile onto your face you lean them forward and intone, in your best slut voice, "Hey."

His eyes alight on your huge hooters as you run your hands over them again, this time wrapping your hands around your nipples and giving them a tug. Your mega-tits jiggle in response.

"Come on professor," you say, biting your lower lip. "Don't you want me to wrap these around your biiig haaaard cock? If you take over my body you'll never know what it feels like to fuck these titantic titties."

He wets his lips and stares. You almost have him hooked.

"You can lick them and suck on them and then I'll wrap them around your cock. Don't you want to spunk all over them?"

The machinery shuts off abruptly and the electric burning fades. A woosh of fans suck the gas out. Frankenstein flips a switch on his controls and a mechanical ring descends from the ceiling of the cylinder. As it lowers to your neck's level it contract with a thump and a tight locking around your throat. It isn't particularly heavy or even uncomfortable. It actually feels like it is made from silk.

"That ought to make you behave," says Frankenstein. "One false move and it will cut off your air. Kill me or even knock me out and you're as good as dead."

He thumbs another switch on his controls and the cylinder opens with a hiss. The cool air of the laboratory causes you to shiver. You try not to look at the naked monstrosity on the table nearby or Kat Meadows, who is idly watching what is happening. You keep your focus on Frankenstein. The elderly doctor is practically drooling at the sight of your mammoth mammaries swaying right for him.

He embraces you and buries his face in your huge cleavage. You can feel his breath and his slobber as he smothers himself in your warm titflesh. His hands trace the shape of each breast and he lifts his head only after thoroughly enjoying the valley between your tits.

"Yes, these are perfect. How do they feel? No, don't tell me. I want to find out for myself. Now, let me suck on them."

It takes both of his withered hands to lift one of your immense tits and direct them nipple, big around as a thumb, towards his mouth. He licks your areola first, tracing its shape and spiraling his tongue inward towards the nipple itself, before licking it with great enthusiasm. You moan and pull his head against your breast, gasping as he open his mouth and sucks. The nipples are so sensitive, his attention feels amazing.

He doesn't spend long playing with your tits before he commands you to lie back on the floor. You obey, your massive meatbags spreading out and overflowing your torso and your huge nipples, glistening with his saliva, sticking straight up. You press your tits together with your arms, creating a massive mound of mashed mams for him to aim at.

Frankenstein is in a frenzy to get his pants down. His hard cock springs free from his trousers, it is deep red and dripping with precum, a good size surrounded by wiry white pubic hair. He kicks off his pants and stands over you, lowering himself on his knobby knees and guiding his prick to the line dividing your compressed breasts. His cock sinks into your cleavage, disappearing entirely from view in the warm valley of your titflesh.

"Ohhh yes, lovely," he says, grabbing a handful of each breast and working his hips. You feel his precum-lubed cock between your breasts, but you can't see it. He fucks them quickly and with growing excitement, his cock driving a warm path between your titmounds. Suddenly, he arches his back and shouts. Cum bursts from between your cleavage onto your throat and you feel him twitching, pouring out a huge load of his seed onto your neck and between your breasts.

Gasping, he falls back on your thighs as you allow your breasts to settle apart and reveal the sticky mess he's made of the rubbed-red space between them. Almost without thinking you drag a finger through the cum painting your chest and bring it to your lips, sampling the perverted doctor's salty seed. Your own lust still has not been quenched, maybe if you draw this out he will think twice about sticking you back in the cylinder.
