The desperate attempts of the feral Andrea, who tried to make you surrender your humanity and give in to your feral side kept going, she let out multiple lusty growls as she tried to get rid of your human mind, although, for a moment she paused, to then take multiple deep breaths, not due to the sex induced adrenaline, but due to exhaustion.
Your reptilian eyes lit up as you saw an opportunity, specifically to free yourself as your human mind cleared from the rush of sensations and feelings, with another, more intimidating reptilian roar, you pushed Andrea to the ground, letting out a hiss of suprise due to your sudden surge of strength, to then pin her to the floor, holding her hands as she tried to struggle free.
That's when you suddenly had a thought, if her own fluids managed to make you more muscular, then surely your own fluids should have an effect on her, infact, your reptilian seed already did have some form of effect on Andrea, her breasts seemed bigger and her form appeared to be more slender and attractive, but most importantly, her reptilian face didn't show the same feral aspect she had before, maybe the antidote mixed with your fluids and it slightly worked its effect on her! Or maybe, the antidote you already injected prior to her transformation didn't have time to work its effect, so maybe, your reptilian seed is triggering it.
With a growl, you forced one of your reptilain dicks in her mouth, letting out a hiss as you felt her reptilian tongue brush against it. You then proceeded to stroke your second dick, until you reached climax, forcing your reptilain seed in her mouth. You then pulled back as you awaited to see its effects, hoping they would restore her humanity.
