Red dragon vial hoping that if he couldn't fix her, he would at least join her.
Mary felt the heat rising up in her, like it might burn through her skin.
Mary roared, sending fire high into the air as the second vial took effect.
Her body began to grow in short bursts, first to 30ft then an additional 10ft per burst. Each one felt like a full body orgasm.
"Oh Jeff, uh(growth), I'm ( grow), so(grow), uh(grow), sorrrrRREEEYYYAHHHH!!!!!", Marry yelled as that last one caused an actual orgasm. Mary's claws were digging into the ground, her lengthening tail breaking trees behind her. 70ft. 80ft. 90ft. 100ft. Each burst more thrilling than the one before. But additional changes were taking place that Mary was not aware of.
Mary's single row of black spikes running down the length of her body were joined by a new row on either side with the original growing larger. Her two horns on her head were joined but 3 more pairs of horns, giving her the look of a crown of horns with two horns on the sides of her head curling forward, with the others pointing backwards.
130ft. 140. 150. 160.
Mary's body began to grow past the trees easily topping the massive oaks near the cabin.
200. 210. 220. 230. 240. 250.
"Oh god, when is this ending? OH!!!", another actual orgasm hit her like a truck, but the pressure in her vagina drew her attention now. A final long burst of growth pushed her into 450 ft tall at the shoulder and a length of nearly 1000 feet long from nose to tail tip.
"Oh now what?"
The pressure reached a point and instinct kicked in and as she watched an egg fell out of her. Shunned, she edged closer to the egg smelling it. "It's alive!", said Mary stunned, "but how? I never had sex, how can it be fertilized?"
