Meg's Coming of Age 07

Alien thoughts start to invade her mind, vengeful and aggressive, while the fiendish metamorphosis continues up her body. Megumi's hips widen, rebuilding themselves on a stupendous new scale, while twinges of pain like a thousand small balloons popping force its way into her stomach. She throws her head back, mind staggering, eyes rolling up, as the pervasive tsunami of bodily sensation washes over her. The veins and arteries in her abdomen and chest pulse and pump larger, solid plates of muscle violently inflating into being while her shirt stretches and finally bursts open over her expanding breasts.
