Learn how to stretch a woman

"Phyllis," said Paul, feeling a bit strange referring to her by first name, "I'm not sure I can do it ... I mean, I was just with Mrs. Hunter ... "

But Paul trailed off as he gazed Phyllis's breasts. They were somewhat smaller than Miss Hunter's, but they were getting juggled in intriguing ways.

Phyllis smiled. "You're a tit man, aren't you, Paul? I've always loved tit men, they're so easy for me to lead on. Have you ever been tit fucked, Paul?"

"Mrs. Hunter took it ... me ... between her breasts and then sucked on it ... on me."

"Mmm, yum! I think I'm going to do that to you too."

The idea of getting pleasured by two hot women in a row stirred Paul's blood -- enough that he sprang back into action in no time.

"Oh, fuck!" Phyllis sighed happily. "Now, Paul, as your biology teacher, I have to inform you, that most of the time the female has a vagina averaging eight inches in length, and what the male inserts tends to ... fall short of that. But you, you turn everything around ... you will need to learn how to stretch a woman to accommodate you."

"I don't want to put a woman to any trouble."

"Trouble? Paul, women will be thanking you. The secret truth is ... LOTS of women want to be FILLED with cock ... and you've GOT to share this giant cock of yours!"

Paul gasped as Phyllis knelt before him, clasping his length in her cleavage and licking him like a great lollipop, then eventually managing to shove her mouth down over his fist-hard glans. "Oh, Phyllis ... you're good!"

"Yes, well, I do know my biology! And now that we've got this bad boy good and lubricated ... "

It was somewhat awkward, using the flat top of the desk, but Paul didn't much care. He lay back as Phyllis straddled him, shoving her tits at his face as she concentrated on sitting herself back down over his shaft.

"Stretch my pussy, Paul ... yes, that's it, stretch it! Deeper, Paul! More! More!"

Paul was slightly concerned about how red-faced and teary-eyed Phyllis became, but she kept insisting "More!" and so he grabbed her hips and obeyed, until at last she was stretched to the hilt with his cock.
