Mark eased her down on the couch and broke the kiss. Katie lay there flushed and panting as he fondled her gorgeous big tits. She was squirming with horniness by now, and she just couldn't stop her hot creaming. She couldn't kid herself, either. She wanted the handsome professor to fuck her silly. If he wanted to, she wasn't going to resist.

"Mmmmmm, Mark, you're getting me so excited!" she moaned.

"Good," he said. "We're going to have a wonderful time together, Katie."

Katie was sure of that. She just lay there and gurgled with excitement as he teased her nipples into long stiff nubs. He dipped his head down, stuck out his tongue, and began lashing it over her engorged nipples. It felt so sensuous, she couldn't help moaning and writhing.

Mark must have seen that she wouldn't fight him. He didn't ask permission to take off her jeans and panties. He just did it. She lay there naked and trembling as he studied her small, neat blonde bush. He slid his hands between her thighs and touched the scorching wet flesh of her gash.

"You're very turned on, aren't you, Katie?" he asked gently.

"Yes, I am!" she moaned.

"Excellent," he said. "This is going to be great. I want you to take my clothes off now. Don't worry, the door is locked."

At that point Katie didn't care about the door, either. She didn't care if somebody walked in on them. She started pulling off Mark's clothes and ogling his hard tan body. When she got down to his shorts, her hands were shaking. She peeled the shorts carefully down over the big hard bulge at his crotch.

She gave a hoarse little moan when she saw his cock. It was the biggest one she'd ever seen, and it was hard as steel. It wagged stiffly before him, oozing thick globs of cream. The wrist thick shaft bulged with blue veins. Katie petted the engorged hot column of meat.
