Add another finger.

Carl looked at Steffi's ass hole slightly stretched around his single digit and stroked his second finger into place as he withdrew it. Steffi looked back over her shoulder. She knew what he was about to do, her face seemingly saying don't do it. But Carl could see in her eyes that part of her was intrigued by the sensation she was getting in her ass and wanted to try more.

"Carl....I don't think-ahh..." Steffi began as he pushed two fingers inside her.

Carl was loving the sounds Steffi was making as he pushed two fingers inside her. He thought her ass was tight before, but he literally couldn't move his fingers around - or feel the circulation. He pushed past the first knuckle and the second, watching Steffi writhing underneath him.

"Don't worry, the thermometer is kind of big so I wouldn't want to under-prepare you." It was of course, all bullshit. The thermometer was in fact slightly smaller than his finger.

"Ohh..Kayy.." Steffi moaned out. Carl could sense she was getting more aroused as he pushed both fingers all the way inside her.
