She keeps at it, and keeps growing, throughout the week.

It soon became clear to Tom that what he’d experienced wasn’t exactly a one-time thing. No, every night afterwards, Sarah would come to him in the evening, stopping him from whatever he’d been interested in otherwise, forcibly take him into the bedroom, and rode his cock as much as she wanted to. The more she did it, the less she was checking in with him to make sure he was going okay. In fact, it seemed to him that she was taking less and less notice of him in general.

This all went hand-in-hand with further growth. By Friday, she was well past eight and getting closer to nine feet tall in total. She was having to kneel to get in and out of the doorways, and her head was starting to get close to scraping the ceiling when she stood at full height. That night, she grabbed him, not in a fireman carry like all the times before, but with her hands around his midsection. It made Tom feel small, helpless, and very very aroused.

In order to ride him, Sarah had to lay down horizontally, otherwise her head would be going through the ceiling. “I’m so big,” she breathed, working with one large hand to try and get Tom’s cock into her pussy, and struggling. Even when he was in, both she and he weren’t getting as much enjoyment as they had before. She’d grown to the point now where they were barely making contact. “I can’t feel you at all,” she said, her voice almost a growl. Then, Tom saw the glint of an idea in her eyes. “I know...”

Sarah started switching their positions, with her laying down on the bed, on her back, taking up most of it by herself, and setting Tom near her pussy. He didn’t need to be told what she wanted, and still feeling hard as a rock, he reached out and started rubbing her clit. It was big enough now that he could fit his entire hand on it, and squeeze it, though he knew to be a little more gentle than that. From the way she was shaking and moaning, he was doing a good job. But it also wasn’t enough.

Suddenly, Tom found he was being grabbed again, and repositioned. Sarah was shoving his head into her folds, and his arousal somehow soared even higher as he got to work immediately, licking the inside of her as best he could. She was almost big enough to pop his head into her vaginal space completely, and the thought of that made both of them get even closer to cumming. When Sarah reached her orgasm, Tom could feel the walls of her pussy contracting and squeezing on him, and he couldn’t help cumming himself. The size difference was really that big now, he realized. He couldn’t be his wife’s sexual partner, not really. Only her sex toy.
