You think it's too late to back out now

Goodage lets out a low long groan as he pushes his dick into your ass. You feel as though you are being split apart as he thrusts his cock three inches into your anal cavity.

"Oh fuck yes," he grunts as he begins to work his cock back and forwards in your tight hole, pulling your buttocks apart and pushing deeper with each lunge.

For you the pain is almost unbearable, but also somehow arousing, his dick feeling twice as big as you remember. You ass has relaxed a bit and Mr Goodage is now working the whole length of his cock up your butthole, pumping rapidly in and out while your tight anus clutches around his organ.

Goodage slaps your butt as he increases his pace, this is all his fantasies coming true.

"Ahhh!" he yelps as he thrusts himself deeper than ever and holds it inside you, his cock twitching and spasming with his eruption. You moan yourself at the arousing sensations of his cum pulsing up your ass and dripping down your inner thighs.

"Oh yes," he breaths as he withdraws from you tight ass. He rubs his hand across the smooth cheeks of your buttocks, "You've got yourself an A+ my lovely backdoor girl."

Although you're not too sure about his new nickname for you, you're definently happy with the mark. Time to get cleaned up and on to the next class.
