She brought him to her bedroom. "Ok, you have this fantasy of 'wanting to know what it's like'. Pretend you've woken up in my body. Now what?"
They stood in front of a full-length mirror.
David looked her over in the mirror. She was in her early forties, with a flabby mom body and an old, tired face. "Imagine this face is staring back at you in the mirror, not just right after the operation, but every day after that for the rest of your life. There would be no way to see your young handsome face in the mirror ever again."
David gulped.
"And I bet you have perfect eyesight. Well, not any more, not in this body. You'd have middle-aged, tired blurry eyes to look through."
David looked down at her arms and hands. Flabby old lady arms and wrinkled hands. "Yes," said the lady, these would be your arms and hands. Nowhere near as strong as a teenage boy's. That testosterone, that upper body strength, completely gone. Just enough strength to do chores, and even that is tiring. You can say goodbye to sports, to lifting anything seriously heavy ever again." She flexed her arms weakly to make David think it over.
David looked down to her jeans, tightly wrapped around her thick, flabby legs and ass.
"Yes, we moms get very thick in the legs." She rubbed a hand over her backside. "It's so hard as the hips and ass get wider and thicker, and no way to go back to the nice thin silhouette we had as girls. You'll be forever stuffing your fat ass into jeans that never fit right, or into skirts and dresses that make you look dumpy and maternal."
David tried to imagine having such a fat butt instead of the simple, flat male butt he currently had. He rubbed a hand over his own butt which was nothing like hers. "It's like a huge pillow you have to carry around in your pants, isn't it?" he asked.
"That's right, and so is this disgusting flabby stomach, all stretched out from multiple childbirths. She lifted her shirt to show him the wrinkles and stretch marks all around her midsection. "This never gets tight again, just flabby, wrinkly and disgusting. You'd have a belly just like this. Fat flat tire and muffin top, just for you, and you can never take them off, you'll be wearing them forever."
"Speaking of which..."
"Yeah, you wanna know what it's like to have tits?"
David was embarrassed, but the conversation was getting to him. He was fantasizing intensely about what it would feel like to be in a mom's body. It sounded like a nightmare, and it was, but it was an incredibly tempting nightmare. He was a little red from embarrassment and his dick was swelling at the thought, but he had to keep going.
