As they have sex, she pushes for it to get rougher

It was easy for Tom to carry her into the bedroom, now that she was made of such lighter 'materials', and she spend the entire way there rubbing against him and kissing him. Once they were there and both disrobed, she lay out on the bed, flat on her back, legs outspread. "Come on, I'm ready~"

He couldn't see any sign that Sarah was wet in any way, despite looking inside of the soft felt cavity that was her vagina now, but he decided to try anyway. Starting slowly, he found entering in her...well, not easy exactly, but manageable. The feeling of her silky inner walls was so different from a human being's pussy, and his cock glided inside her while still feeling tightly gripped.

Still, he was trying to be careful, exploring this carefully...until Sarah told him, "Faster, harder! I can take it, I can take anything!" Tom did as he was asked, speeding up and putting more **** behind his thrusts, but even as she moaned from his cock, she still called out, "Harder!" and "Faster!" when he thought he was doing well. At some point he was well and truly past the point where her old self would have called for him to stop, where his squeezing and thrusting and slamming would have been too painful to take.

But she kept asking for more. And he gave it to her. At first, Tom found it difficult, because this was his wife. Even thinking of the wish, of how she wanted to be able to take the pain without really being hurt, didn't help.

What did the trick was really...feeling her. She's not a person, I have to stop treating her like one. She's a stuffed animal, a toy, like she said, she can take anything I can do to her. Changing his point of view, forcing himself to see her that way, freed him up to absolutely thrash her with his cock. She couldn't even talk, all she could do was moan and moan and moan, loving being fucked so hard that with each thrust, her body compressed into the width of a cheap paperback book.

Tom couldn't help but pause, however, when he heard a very distinctive sound: her stitches starting to rip. Pausing in his thrusts, he looked to see that the seem connecting her pussy pocket to the rest of her crotch fabric was starting to give out under the strain. "Um, sweetie, maybe I should-"

"No!" Sarah called out, sounding equal parts euphoric and annoyed. "Keep it up! Let it rip, I'll be fine!" Unsure at first, Tom took a moment to remind himself again. She's just a stuffed animal. Rips can be fixed. Mended. She wants this. The slutty fucking plushie wants me to rip her pussy apart.

With that mindset back in place, he was able to disconnect again, fuck her just as hard as before, if not harder, and now the sound of those stitches under strain only made him harder. "I'm going to tear your pussy up!" he told her, and she moaned in reply. The first seam finally gave up, a rip forming that exposed her fluffy insides. But he kept going, harder and harder, and more stitches failed, until finally her pussy was pushed into her insides, and now he was just fucking her soft, heavenly fluff.

The very fact he'd literally fucked her pussy so hard he'd ripped it out completely was enough, and he finally came inside her. His cum was quickly absorbed by her fluff, to the point that when he did pull it out, little white pieces of Sarah were clinging to him. "Are you...okay?" he asked.
