“Now you’ve fucking had it!” she spat seeing his face grimace realising the game was up. He paused for a moment then looked down with a grin.“...A good five to six minutes away,” he said spinning her around pulling her up to him her tits thrusting forward his big arms and wide hips easily opening her thighs. “Five minutes you won’t forget in a hurry!”The sirens never seemed to get closer. Was it five minutes or ten, Mandy couldn’t tell? It was difficult to control rational thought or keep her. They started doing this and when everyone was finally picked the party quieted down and the music turned off. The parents announced that this time it would be an oral competition. So we all got blindfolded and were directed to our seats.I sat down and felt my girl lower down in front of me, her stroking my thighs to get me warmed up. The rules said that there was to be no other contact before the round started, though. When everyone was seated the parents told everyone to take their blindfolds. After a few minutes, she orgasm again. This time she flooded my mouth as she thighs clamped the side of my head. I licked her pussy some more. Her body fell down the side of the table as she orgasm again, and again. After a few minutes she rolled over on her stomach. Her legs fell down to the front of my feet. She eased her big body back on mine. She guided my cock into her pussy again. I grunted as she slammed back on my cock. I gripped her wide hips as I slapped her ass. I then moved her on.
