Dr Cox is back in 4K and has invented a new cock growth formula. She has grown tired of hearing all of her patients little dicks problems, after years of testing she finally has it. Never again will any woman be unsatisfied by a little dick, I'm going to change the world to a bigger better place. She tries to act like a good respected scientist conducting studies on how to cure illness. But really she has her own secret agenda, she has a big secret she is a sex crazed bitch who wants to create the perfect formula to grow cocks to inhuman size, monster sized dicks so they always have enough cum for her. But first I need to try out the new formula on my test subject who was more than willing to volunteer to see if it has any effect on his tiny 3 inch cock. Take a sip of the formula and immediately the cock grows, the shaft has got longer and thicker. Take more of the formula, I'm getting horny from watching that dick grow more. Now your a real sized cock, I can see that the tip is leaking some pre cum, the smell and taste of that cum gets me so horny as I lick the tip. I strip out of my lab coat to reveal just my bra and nothing else on underneath. You see I knew my formula would take effect instantly and I just can't resist a big cock to play with. She starts jerking and sucking on that big cock and wants a big load all over her face, sliding that dick between her big tits. She wants more of the cum, she can't contain herself she needs to taste more and get covered in cum dripping down her face onto her big tits. The test subject blasts over her face - a slow motion shot so you can see my face get plastered with cum. Blowing bubbles and playing with the cum, licking her fingers. She loves the taste and tells her subject to take more of the formula, she wants to ride that dick and feel it stretch her pussy. She needs breeding and wants to be constantly fucked and filled with cum so she can be impregnated. She cannot control herself, she rubs some of the cum she spat out from her mouth onto her pussy and plays with herself. She wants his big dick inside her and wants to ride his cock until she drains his balls deep inside and he impregnates her. She is practically begging to ride on top of him and bounces on his dick hard and fast until she gets what she needs a big huge overflowing creampie to fill her cunt. She has an amazing orgasm from the feeling of the cum gushing inside her and filling her tight hole up. Never has she been filled so much and the feeling is overwhelming, ahegao orgasm face. The cum is dripping out of her and she rubbing it all over her body, excited from all the pleasure and eagerly awaiting more of that awesome cum she desires. She wants that dick in her ass now, using the cum from her pussy to play with and fingers her ass. She just wants to feel that cock stretch her tight ass out and the subject is gone so horny and his balls are so full of cum he cannot resist he needs to unload and fills her ass up with a big creampie. She cums again as the cum unloads in her ass and she pushes it out.While she recovers from that amazing orgasm, she lies back to play with herself a little, she still is so horny and wants more cock and cum .She tells him to take more of the formula and his dick grows to an magnificent length over 12" now! Holy fuck, its so big I can barely get my mouth around it! She strokes the big shaft, a daft grin on her face and her eyes wide open sucking on the head. Oh just give it to me in my cunt again, yes fill me up! He fucks her while she spreads her legs open and lays on her back. That cock is huge so big and it has grown so much impressive results. But even now that's not enough for her, there's still some of the formula left. She pauses and thinks to herself for a moment. If the growth spurt increases that much from him it, what if inject it directly into the big shaft I wonder what effect it would have. Compeltely covered in cum and being the horny mad bitch that she is, she injects the last of the formula with a syring into the dick and the effects are inhuman. The dicks has transforms into a gigantic tentacle dick! Like nothing she has ever seen before, I've created a monster! She sucks on the tentacle slapping it against her face and tits.She must have ingested some of the formula because now her hair is blue just the like the tentacle monster dick. It has had side effects on her too but she does not even care, she's lusting at the sight of this monster she has created and wants to ride it. One big final orgasm and she cums again for the monster toys fills her up. Now she knows she can create a new world full of monster sized dick that can please any woman.
