Fifty-seven-year-old Frank looked at himself in the mirror, sucking in his stomach a little. Despite still running a few times a week he was looking a little podgy again. Time to cut back on the pizza and Chinese food he thought to himself. Selling his small business had given him more time to run, and allowed him to live comfortably. He looked further down the mirror and smiled contentedly.
His pride and joy, his favourite body part, Frank wiggled his hips and laughed as his cock swung about. He'd been blessed with a cock that was 7" long while flaccid, and 10" when erect. When younger he'd never been afraid to miss an opportunity to show it off, most often pretending to be accidentally showing off his bulge in his tight trousers or shorts, sometimes he'd run through the woods and flash at women while there. He still did so, but was more selective in who and when he flashed.
A few times it had led to sexual conquests, part of the reason why he'd been divorced three times. To be fair, his last wife had cheated on him first. But, it had only been the once and Frank had more than paid her back afterwards.
He pulled on his vest top and running shorts, tied his trainers, and went out. He didn't run so far these days, not as much as he did when he played football regularly into his forties. Nowadays he set a limit of five miles and knew he'd be back within the hour.
Today, he hoped to see his new 'friend'. Frank had a particular route through the woods and back, and on one of his runs a couple of weeks ago he slowed down when he heard a clicking sound, pausing and looking through some trees to see a girl taking photos of herself using a selfie stick. Moving closer he noticed she was naked, her clothes in a pile on the floor beside herself. She was older than he'd originally thought, around thirty years old.
Frank watched for a couple of minutes as she posed for the camera, taking several snaps, before getting down onto all fours. Her arse faced right towards Frank, round and peachy, and Frank pushed his shorts down a little and released his cock. He stroked slowly, then bit the bullet and moved closer. A branch snapped under his foot, and the woman turned and gasped seeing his cock in his hand. Frank smiled at her reaction, then frowned as she quickly gathered up her clothes and ran towards the pathway. It was a pity, she was hot, and he would have loved for her to beckon him over, even if just to let him watch.
She wasn't there, Frank resigning himself that mental images of her would have to suffice. The run was uneventful and getting home he went in through the back door and into the kitchen.
"Oh, hi Gramps," a female voice said.
Tiffany was Frank's granddaughter and now lived with him. They'd always been close, she'd always confided in him about her parent's constant arguing, telling him that his daughter, her mum, was worse than her dad. The day after her eighteenth birthday she'd snapped after coming back to another huge row, and asked Frank if she could move in with him now he had his house to himself again. Frank agreed, he'd always liked Tiff, as she preferred to be called, and a month later when her parents split up she stayed with him, saying despite everything she didn't want to anger either of them by choosing one to live with over the other.
Tiff stood in front of him, wearing just a skirt and her lacy green bra, Frank opened the door just as she was throwing her t-shirt in the washing machine.
"I spilt something down it," she said by way of an explanation.
"Mayonnaise was it?" Frank asked, pointing at her skirt where there were more stains.
Tiff blushed and unzipped and pulled down her skirt, throwing that in the wash too. Frank laughed as she did so.
"You get more like me every day," he grinned.
"I have no idea what you mean, I'm a good girl," she giggled.
Frank peeled off his sweaty vest top and threw it to her, telling her to add that to the load.
He looked at her standing in front of him in just her matching undies, her petite body curving in all the right places, a sight to behold. If she wasn't his granddaughter he would have whipped his cock out there and then. He shook his head, annoyed with himself for thinking it. She is your granddaughter he scolded himself.
"I'm going in the shower, I'll sort tea out when I come down," he said.
"The girls are around tonight don't forget," Tiff said.
"I'll do Spag Bol then, you all enjoy that," he grinned.
Tiff and her friends were a close bunch. They'd met at college, and instantly bonded. Like Tiff, Eve was only 5' 2" tall, Jess an inch shorter at 5' 1" only. Frank knew from doing the washing that Tiff wore a 32C bra and both of the others must be around the same, all being very similar body sizes. The other coincidence was they were all born within one week of each other, their nineteenth birthdays would be the next month. It reminded Frank he needed to sort out a present for her.
They could quite possibly have passed for sisters, with one striking difference between them. Tiff was a brunette with brown eyes, Eve a redhead with green eyes, and Jess a blue-eyed blonde. There'd been quite a few times over the last few months when Frank had nearly blushed hearing some of their conversations, describing their sexual conquests with each other with complete freedom.
"I've got all the ingredients out ready," Tiff shouted upstairs when she heard the bathroom door open.
"Won't be long now," Frank answered.
He stood in front of the mirror again, watching the beads of water run down his body before rubbing them off with the towel. He started rubbing his hair dry and thought he heard the stairs creak. He'd left the bedroom door open and wrapping the towel around himself, went and checked, but nobody was about. He threw on some old jog pants and a loose t-shirt and went to the kitchen. Tiff wasn't in there, but she had placed everything neatly out. He started cooking, then Tiff reappeared looking flushed.
"You okay, I thought you were still down here," he said.
"I went to the toilet," she answered.
That must have been the creak he'd heard then. The food was nearly done when the doorbell rang and Tiff let Eve and Jess in.
"Right on time, sit down girls, I hope you're hungry," Frank said.
