Mandy raised up and offer her hard nipple to her father. She slid up and kissed her father passionately. They hungrily played with each other's tongues moaning in pleasure. Mandy started to grind against her fathers cock with her warm wet pussy. His cock instantly responded and grew to its full length. Mandy reached beneath her and started to stroke his wet shaft.
This was more than Fred could take. In one swift movement he lifted his daughter up and guided his cock inside her once more. Mandy loved blow jobs more than anything but she was beginning to love her fathers cock inside her almost as much! Father and daughter increased the pace of their fucking. The sound of sex filled the room and drove Mandy over the edge. She screamed in ecstasy as Fred continued thrusting into her. Within seconds he had joined his daughter in orgasm and deposited his seed deep inside her. "I hope she's on the pill." He thought.
There was a knock on the door! Mandy rolled off the bed and slid her mask back on. The door swung open just as she was smoothing her mask into place.
"My god Fred!" Said Mandy's grandfather. "Did you forget about our fishing trip this morning? I've been out there honking for 20 minutes at least."
Mandy's grandfather froze as he noticed the naked girl on the floor. He looked her up and down. "I haven't seen boobs like that since your wife." He told Fred. Mandy's mother did indeed have nice boobs.
"Dad, this is a young lady I met at the party last night." he stammered. "She was just leaving."
"You don't have to go on my account." Mandy's grandfather told her.
Mandy noticed that there was a huge bulge growing in her grandfather's trousers. It looked like it might rival her dads! "You always used to share your party conquests with me Fred." He told Mandy's dad. "Don't go getting greedy on me now."
Mandy's grandfather was taller than her father. He had a thick head of grey hair and was clean-shaven. He was in very good shape for being in his sixties. He started to advance on Mandy with lust in his eyes.
