He continued just enjoying having her like this before he suddenly popped the tip into her, and slid her all the way down the shaft with a loud, low moan.
He moaned lowly and switched breasts. They were massive now as is, how much bigger would they get when- as if he wasn't in control of his body, the thought of kids was now making him move faster and faster.
He let out a howl and bucked hard into her as he slammed her down onto his cock again and again, fantasizing about how wide her hips would be. How soft she would be, how many kids he could give her. Naturally, as many as she wanted. Two? Six? He didn't care.
She screamed over and over, wondering just what he was thinking about, but more glad he was having so much fun. In truth, she really did like when he got a little wild like this; it really did make her feel desired. She was getting older now, already in her late thirties. She was happy her husband thought so fondly of her like that.
