The woman removes a cushion from the wall, near the cushion that had been a cupboard, and reveals a large mirror. She stands proudly in front of it, admiring her enlarged posterior. She bounces it up and down, watching it move and laughing as it moves. You also look in the mirror and see yourself. Your face is mostly the same: a feminine version of your former self. But your body is unrecognizable. Your breasts are big and turn you on, your pussy is strange-looking, but also hot and you wish you had met yourself.
You recall that you just had sex with someone with a penis. Temporary though it was, you never would have done such a thing an hour ago. You've changed, not just your body but your mind. You are scared. What else will you allow yourself to do when your mind continues to change?
You remain standing, a little unsteady as your habitual posture keeps fighting against the massive breasts weighing you down and pulling you forward. The tension in your torso continues until you finally feel it begin to settle behind the pair of nipples immediately below your breasts. You close your eyes, knowing what's about to happen, but you still shudder in frustration as it happens. The flesh below the second pair of nipples begins to swell, pushing out. The sensation is incredible and you fight to remain on your feet. Your vagina gets into the action after a couple minutes of swelling and the resulting pleasure forces you drop to your knees to keep your balance. As the second pair of breasts grow, the new curves stick to your original breasts, and you have to free them from each other several times, letting them bounce back into their proper place.
When it's over, you stand back up and find yourself even more off-balance. You stand leaning back, so the heavy flesh sacks don't topple you over. You see yourself in the mirror and gasp in horror. You've seen many sexy women, but you've never seen a woman with four big breasts like you. The lower breasts push the upper breasts up so they have even better form than before. When the swelling begins in the third row of nipples, you lie down, helpless. You orgasm, and you orgasm again. When you try to stand at last, you are leaning back so badly you look like you are carrying bags of flour, and your whole torso is covered in eight thick-nippled breasts fighting for room.
"I don't think that's the end of it," says the woman, smiling.
