How he imagined it:
The old man sat in a deck chair looking over the beach -- watching a younger (younger hell -- she's in her 60s) woman walk up from the shore. She was nude except for a swim mask and snorkel pulled up on her head and was carrying a spear gun and two fish. In spite of her age, her body showed the fitness of a woman who swam daily. She came up to the deck, gave him a quick kiss and puts the fish into a small refrigerator.
"Happy Birthday Professor" she said "I'll clean these later, do you want anything?"
"Call me Jack -- can you hand me a beer."
"Its 10 in the morning, are you sure?"
"I turned 100 today, I don't think a little indulgence will hurt" he said
"OK, I'm going to rinse the salt off" she said, handing him the beer. She stepped over to an outdoor shower. It was fully in the open, but the cottage was secluded and no one outside of the property could see. When she was finished, she put on a floral print beach wrap. The colors reminded him of Monet's Lily Ponds. The sheer fabric did nothing to hide her body -- her nipples were clearly visible along with the dark triangle of her pubic hair. "What are you looking at?" she asked Jack, "you've seen me like this a thousand times"
"I've seen a thousand sunsets, but I still look at them. They are beautiful and so are you," he said
"How are you feeling this morning?" she asked
"I'm stiff where I don't want to be and not stiff where I do," he said
She reached down and patted the front of his swim trunks. She grinned and said "I feel you are a bit stiff here as well."
"And the rest of me is scrawny and wrinkled -- doesn't my body scare you?" he said
"I'm 67 years old and I've seen lots of bodies," she said.
"As ugly as mine?" he asked.
"You do win the prize, but parts of you are very nice" she said
She leaned over again and pulled his swim trunks down to his ankles and then began stroking him into an erection.
"Nice to know it still works -- sort of" said Jack
Christina lifted her beach wrap, then straddled Jack's lap, slipping him into her as she sat down. Both of them quietly enjoyed their co-joined bodies -- Christina moving her hips just enough to keep him stimulated. Jack pulled her closer and told her he loved her.
"Hello the house!!!"
"Someone's coming down the path" said Christina, standing up, then pulling Jack's swim trunks back in place.
"Hello, are you Christina -- It's Jen, were you expecting me?"
The woman was about 70, but still in shape. She was wearing a White sleeveless blouse and tan shorts. Jack noted how her breasts moved under the blouse and thought she likely wasn't wearing a bra.
"I brought your mail -- it looks like a bunch of cards"
Christina shuffled through the envelopes and said "this makes 127."
As Jack's 100th birthday approached, Christina had contacted the Alumni newsletter and asked that Jack's former students send him a birthday card. Her goal was 100 cards for the 100th birthday. Most of the greetings were electronic, but quite a few, like the ones in her hand, were physical cards sent through the mail.
"Professor Burns, Do you recognize me?" said Jen.
"Jenny Carpenter," he said.
"I used to be Jen Carpenter -- now I'm Jen Fischer," she said.
From Christina "Would you like something to drink? We have juice, water, the Professor's having a beer, and we've got wine -- both red and White. I'm drinking pomegranate juice."
"It's early, but I'll have some white wine if it's OK" said Jen. She leaned over the table to pick up her glass. Her position gave Jack a good view down her blouse -- no bra there!! As she sat down at the table, Jack realized he could see up the leg of her shorts -- no panties either!! "What's going on?" Jack thought.
