She doesn't even wait for an answer

"You know what, it's a little too warm for this sweater today anyway!"

Without a moment's hesitation, Ms. Dalton pulled off her top as casually as she would take off a coat, revealing a lacy black bra that really showed off her tanned breasts. They weren't exceptionally big, but there was enough there to jiggle some as she adjusted her underwear in front of the whole class before turning to William.

"What do you think? Are they good enough to hold your attention for a whole hour?"

"Y-Yes, ma'am. They're beautiful."

A collective awww filled the classroom, but the instructor just blushed.

"That's very sweet of you, William, but I am your professor. Let's try and keep things professional, okay?"

Professional?!? She was standing there, shaking her tits and asking William if they're hot enough for him to enjoy staring at, but he's unprofessional for complimenting them? God-damned double standards...

Ms. Dalton launched into the standard first-day spiel -- introducing herself, having the students introduce themselves, and going over the syllabus -- her chest bouncing every time she moved. A lot of that information was probably quite important, but William couldn't hear a word of it above the throbbing in his pants. His rock-hard erection was pressed against the denim of his jeans at an uncomfortable angle, and after all the extra attention this morning he wasn't sure he could adjust himself properly without anyone noticing.

Then someone told a joke good enough that Ms. Dalton literally doubled over in laughter. The sudden change in angle and the additional motion of her heaving diaphragm combined to tease her right breast out of its cup, flashing her whole nipple to the class for just a moment before she covered up and whirled around to fix her wardrobe malfunction.

This sudden display only made William's problem worse, but the ensuing chaos gave him the cover he needed to slip one hand down the front of his pants and straighten things out. He couldn't quite stifle a moan at the comfort, and the feeling of his cool, clammy fingers on his hot--

"William is touching himself!"

His brunette neighbor wasn't quite as distracted as he'd thought...
