Before you can reverse the changes, you feel the urge to cum

Stacey is impaled on your cock, wrapped tightly around your now inhuman shaft. There is a massive bulge in her stomach indicating the thick girth shoved up inside her. You need to fix this, you decide, looking down for what she had written. To your shock, you find it almost immediately. "10 inch wide, 2 feet long" is scrawled clumsily across your waist and down onto your left thigh.

You reach for the marker, trying to grab it, but the movement shifts you on the bed, causing you to rock downward slightly. In response to this slight movement, Stacey's **** form makes a rasping sound and her body tightens instinctively. You freeze, surges of pleasure running down your new, huge cock. Every inch of her is tight and hot, and as you just realized, gripping you like a vice. You moan at the sudden movement, shifting on the bed again.

She clamps down once more and fresh waves of pleasure swamp you. Every inch of your cock is being massaged. It feels incredible. You begin to thrust forward, slowly, feeling her tight folds stroke you as she grows wetter and wetter. You thrust faster, the heat inside increasing as you do. Watching her stomach distend and retract, feeling her silky-soft, super-hot insides, it's all too much. You feel something building up inside you. You can't hold back!

You thrust in as hard as you can, burying yourself to the hilt. Her stomach bulges, first from your cock, then from what comes next. You explode inside her, your cock pulsing as you pour semen into her. Your orgasm explodes through your mind and for a second your entire being is focused on your throbbing cock head. You fall forward on her, resting on her distended stomach, your cock starting to grow soft, letting her body start to resume it's normal shape.
