With you on top (alternate)

Reaching down to your purse, you go to get a condom when Mr Williams stops you,

"Don't worry Joy, I had a vasectomy last year."

Taking your teachers' word for it, you straddle the old man and slowly lower your bare pussy onto his average length cock. The thickness makes you gasp as it stretches out your tight teen twat, your hole had never had a cock this thick inside it before and it took you a couple of seconds to adjust.

Your teacher did his best to help you get some extra lubrication by rubbing your clit, which made you gasp as eventually, you feel his pubes tickle your asscheeks. Once you were ready, you started bouncing up and down on his thick rod, your big tits softly smacking him in the face before he took them in his hands and started sucking on your nipples, making you groan even louder.

Mr Williams was in heaven, his former student (actually, one of his favorites) bouncing on his bare cock, her naturally huge melons in his face and her bare pussy wrapped around his cock. Having not had a pussy this tight for a long time, he wasn't capable of lasting too much longer, his thrusts were becoming more and more erratic as his climax drew near. Joy let out a passionate wail as her orgasm hit her which had the trigger effect on Mr Williams of setting off his climax.

Joy groaned as she felt Mr Williams cum splashing against her uterus, she smiled as she leaned down to kiss her former teachers lips, thinking about the fact that her teacher was shooting blanks on her most fertile day.
