"You mean ... other guys need to ... learn this?" Paul wondered.

"Mmm!" Mrs. Hunter broke off her fellatio. "No, just you -- you see, you're very, very specially ... equipped ... and I need to take special care of you, as a special needs student!"

Paul felt reverent as Mrs. Hunter stood away, then pulled down first her crisp business-like skirt and then her clingy panties, unveiling her moistly glistening bush and vulva. Mrs. Hunter hovered over him on the couch and proceeded to playfully pretend to suffocate him with her bulging hanging bazooms.

"Go for it," she teased. "Grab them, squeeze them, kiss them -- suck them!"

After some hesitation, Paul became boob-crazed -- so much so, in fact, that it took him a while to realize that Mrs. Hunter was industriously shoving her vagina inch by laborious inch over his phallic thickness.

"Ah -- but -- Mrs. Hunter!" he worried. "This is sex!"

"No, Paul," she assured him, "this is only sex PRACTICE. It's not like we're getting INVOLVED or anything ... this is simply for your advanced education, so it doesn't count."

Paul shook his head hard. "I don't know ... I don't know ... "

And yet, his uncertainty grew, in direct proportion to how much of him she managed to get inside her. She chuckled darkly, victoriously.
