Grade negotiation (A parody)

Said coed once to prof,
While his dick was in her ass,
"Next month is graduation,
And if I were to pass,

"Then no more could I kiss you
In the shadow of the moon.
And no more could I taste your cock
On Thursday afternoons.

"So you must take the A I got,
And change it to a D,
For maybe grades are all the same
For coeds on their knees,
And maybe grades are all the same
When pricks are being teased."

And so he pulled his cock out,
And changed her final grade.
And then he blew a load on her,
And a small white puddle made.

It mingled with her pussy juice,
And dripped upon his chair,
Where then a cum-stain darkened,
And now no student there,
When visiting his office,
Knows if they should sit, or where.
