After months of research my colleagues and I had cracked the ability to enlarge living matter. We were only in the beginning phase of testing on animals, human trials would be years off. Not wanting to wait I began to make a plan to steal it.

Meanwhile we had discovered with animal trials at work they showed a increased libido, I was worried how this might affect me if this was the case for humans. Finally after about a month I made my move. Not wanting to wait any longer I down the formula right in front of all the others, at first nothing. Than slowly a warm tingling spread over my body, feeling fabric stretch along my skin as my vision began to rise. Lab techs calling for security, and trying to restrain me, as I smile down my head rising higher.

Shoes growing snug upon my feet, as buttons pop from my shirt revealing my chest which seemed more muscular. Belt tightening around my waist as my pants legs rose and started to split up the sides. Feelings of arousal creating a bulge that only stretch the fabic more, sounds of ripping going through the air. Clothing looking more like rags that barely cover anything on my growing body that now resembles a bodybuilders. Everyone starting to flee, as I easily fling scientists about the lab.

Once a pretty big room now a cramped space for the expanding form that was my body. Being so lost in both growing and arousal I never heard the door open, or the faint sting of tasers on my skin. Body pressing into the walls as cracking and screaming echoes throughout the lab. Laughter coming forth at the thought of these little people trying to contain me, distant sound of sirens drawing near to the lab.

(Seeking a female partner interested in either playing all the people I play with or a particular woman, maybe a ex, crush, girlfriend, or a giantess sent by government to stop me from my rampage, etc. All because some scientist couldn't wait for approval for human trials so now he is becoming a towering horney giant as a city has to watch.

Only limits are all parties are adults, and prefer no bathroom related activities. Other than that most size kinks are fine to work in. Looking forward to working with you on making this fun for both of us.)
