Polly's Deception

You awoke to the sound of moaning. Your head feels like a jackhammer and your vision...it's black? No its coming back to you but very slowly. So much sinus pressure. Was the moaning the wind? Someone right in front of you? You had no way of telling as your eyelids are too heavy to fully open.

'James dont...guh hate me, but I took it all.'

'All? All of what?' Your hearing is improving. The voice is very familiar.

Then you remembered, the serum! She took all the serum. You were working on it before heading to bed, but you cant remember what happened after.

With renewed vigor you shot your eyes open.

Your girlfriend Polly sat in a chair no more than eight feet away. Polly was nude and hugging herself in the fetal position, shivering and rocking herself. 

'Polly that was for male enhancement and based on my personal samples, there is no way you can handle a single dose, let alone all ten!'

You struggled but your torso and arms were tightly bound to the chair. 

'Oh but you and I are compatible. I can feel it, your serum re-writing my code to mirror the best parts of you.There is one difference though...'

Polly toes curled in as a gushing sound came from her direction. Ropes of she cum splattered the cushion as something pulsing emerged between her legs. You could only make out the silhouette of it, but it was clear the serum had taken hold.

'Ugh my clit, its working. Its so full and big..is this what having a dick feels like! Ah!

The swollen cliterous thrust past her ankles eliciting several cries from Polly. Her breathing was labored but she reufsed to break eye contact with you.

'I can feel it, the power. How does it look? Its big isnt it!? How does it feel to see your girlfriend surpassing you?!'

On que her mutant cliterous gained an additional three inches. It easily had the girth of a soda can now and was still was growing. 

'Polly you have to stop this!'

'but-but it feels so right! Just look at it, it's your dick on steroids! It's a monster that eclipses the original!'

'My monster cock. It's so heavy and yet!'

Polly face contorted, caught between fear and lust as her body continued to catalize the mutagen.

Her dick was turning a dark shade of red and purple. It violently shook as several more inches of meat push from her pussy. Her clit was clearly well past its intended limits and yet it was thriving. New veins spiraled up the shaft feeding more growth.

'Almost! Almost there!'

With another mighty push the cockhead emerged.

'Ah! Ah fuck!' Polly went slack as her body was wracked by a series of orgasims. While still in a fetal position her new 14" cock stood firm, the thick mushroom head bobbing as her hips gyrated.

'I feel like i just came, but I haven't! I need real release!! Guh- it almost hurts.'

Polly stood, only to fall as another orgasim sapped all strength from her legs.

'Geoff, your mouth.' she began crawlling on all fours,'I need your mouth or I am going to go insane!'

You began rocking the chair, but to no avail. The heavy furniture remained upright and your arms stuck in place. All you could do was pray as your psychotic girlfriend pushed up on your legs for support. You turned your ahead away, but you could feel the heat radiating off her monster rod as it grew further, pushing into your chest.

'Mouth! You're mouth! P-please..I c-cant!'

You turned to find yourself face to face with your girlfriend. She was as beautiful as ever, but completely out of control. She had a snarl and her pupils dilated.

Beneath your chin was the flaring cockhead, it was now the size of a child's fist.

'Dont look at me like that Geoff! If you do i'll i'll!'

The baseball bat of a cock was trapped between your chest and Polly's as she struggled to support herself.

You could feel it stiffen and physically push you further into the chair. In what was no doubt one of the worst decisions of your life, you attempted to speak.

Torrents of thick semen slapped your chin and jetted up your nose and over into your mouth. You could feel thick ropes launched into the air onto to descend slapping your shoulders and hair from above like hail.

Polly was screaming like an animal now. You could feel it, the thick seed traveling up her shaft for what felt like minutes.

You attempted to open your mouth again for air, only to feel the mushroom head of he cock push past your lips.

You wriggled in protest as Polly pinched your nose.

'How do I taste?' A final surge of goey cum began pushing down your throat. You had no choice but to drink as fast as you could to survive.

Just when you when about to passout, she let go of your nose and pulled her cockhead free. She grabbed your cheeks with one hand and pushed in to make your jaw open.

'Mhmm i cant have you pass out, slave.'
