Brian fell asleep just a few moments later. His penis is big, the sensation was great, but I was greedy and wanted more.
Using my time wisely while he's sleeping, I went into my room and fiddled with my chronivac again. Obviously Brian's now unpoportionally large penis was long and satisfying, but was it enough? Of course not! My mind filled with lustfully thoughts told me. So I modified Brian, using the chronivac, so his penis will grow larger. This time, his penis will grow one foot every 10 seconds in his boner, lasting the same time as the previous transformations. Additionally, I decided to change my body so that my pussy will be extremely tight and stretchy, and my body able to take whatever size penis he can put in me.
After a few selfies with the sleeping Brian, I woke him up, a smile of satisfaction appeared in his face. He'd had enough today.
He looked at his watch after a yawn, "I have to go! football training's at 3, and it's already 2.50." He left my home before I can stop him.
I decide to modify my body again for the night, I turned on my chronivac and started modifying my body, I thought as I gave myself stronger muscles for my pussy, how would my small 5'1" female body be able to fit such a long penis if it's as big as me? I wonder.
After dinner and bath, I changed to comfortable tight pyjamas and went to bed.
........The next day.........
The doorbell suddenly starts ringing as someone stood outside, I yawned, awoken by the doorbell. Brian appeared in front of my eyes as I looked through the door. When I opened the door, Brian looked at me and a wet spot between my legs and my errect breasts, a small bulge formed on his dick area instantly. "You thinking what I'm thinking?" He asks. "Yeah" I responded as juices start flowing around inside me.
Without any hesitation, me and Brian went up to my bedroom (my parents have already gone) and we took off each other's clothing. I believe the wet spot on my panties must be my cum when I had lustful dreams the previous night.
Before I could respond, Brian pushed me onto my bed, my lubricated pussy and large breasts facing him. Without any foreplay, he stuck his huge cock, right inside me, my tight pussy. His cock grew larger and larger, I screamed in pain as his cock had been growing so quickly. Brian looked at me, his face as if he wanted to apologize. But the chronic quickly did it's job and my body started becoming stretchy like rubber, as his penis great my body expanded and attached, but my muscles stayed strong as they started milking Brian's dick, I screamed in pleasure, "I'm going to cum, I'm going to cum!" As Brian hits my g spot, pools of liquids start filling my vagina up, forcing it's way out. Suddenly, we both screamed and orgasmed. His dick thrashing ruthlessly in my pussy as I laied down submissively, torrents of juices continued building up inside me, just a few seconds later I got my first female squirting orgasm as my pussy blasted Brian's dick off, covering the whatever's in front of me with my juices, Brian licked his face and exclaimed, hmm this tasted good. I said "ready for next round".
Before I can finish my sentence, Brian stuck his dick into my pussy again, this time it great larger and larger, gradually approaching 7 feet, 8 feet, 3 metres. My body's all streched out as girly screams came from my mouth, continue hardining Brian's cock. I'm all streched out, I thought, but the chronic has just made my body invulnerable, just like a rubber band that can stretch indefinitely while remaining it's elasticity. My pussy muscles clenched onto Brian as I felt another orgasm comming, and another one. I cried "ahahhahahhhhhh".
Brian, a boy with a penis, starts feeling numb as his dick slowly reverted to his original non effect size. As he had blasted all his cum inside me in the process.
However, me, as a girl, isn't done yet, even with me uterus filled with his seed, and me body stretched out like rubber, I haven't had enough.
At this instance, Brian asked me, "how did you manage to take in my ever growing penis, do you have the superpower that allows you to be stretched like rubber?"
I decided to say.......
