Brenda, and Elsie were still remembering their experiences with John, Peter, and especially Ann, who worked in the canteen at the place where they worked.
They would never have thought that Ann was into lesbian activities, and having an incestuous relationship with her two brothers, and even more, into such an extreme pee fetish.......They looked forward to their next visit to Ann's house!!!
In the meantime, they saw Ann every day, and always exchanged smiles, and winks.
..........,...,..........
The sisters managed to visit their parents fairly often, as they didn't live too far away.
However, they were about to get a phone call that would make the coming weekend very "interesting"!!!
Their maternal grandmother phoned, and asked if she could visit for a couple of days.....Violet was a lovely old lady, and the sisters got on very well with her, as they did with all the family.......she had to be 90 years old, but wasn't at all frail, but showed her age.
There had never been anything sexual between her, and the sisters.....in fact, although Violet suspected they had lesbian tendencies over the years, she'd never broached the subject.
When the sisters were young, it was just after the war (WW 2), and during the week when their parents were working unusual hours, (London was a mess for everyone),
they stayed at Violet's house quite often.
They'd seen Violet semi-naked at bedtime, and seen her using the toilet often, but there had never been anything sexual, and the sisters thought nothing of it at the time.
Anyway, Friday evening arrived, and a taxi pulled up outside the apartments, and the sisters went down to meet, and greet her.
Indoors there was lots of tea, and chatting which went on long into the evening, until it was time for bed.
There was a sofabed in the apartment, and they got it ready for Violet.
They watched her undress, and get ready for bed, keeping her old granny knickers on, and turning away when she put her long nightie on.
Not a sexual thought entered their heads......they said goodnight, and went to bed themselves.
The next morning, the sisters got up,and went to the lounge, where violet was just stirring.
Her night bag had tipped over near the bed, and lying on the floor was her purse, and an old looking rubber dildo had fallen out.
"Bloody hell Vi, " said Brenda, " what's this rubber cock doing in your bag?"
"Oh! Dear, you shouldn't have seen that, " she said, her face reddening.
"Why not? "said Elsie, "It's quite normal to enjoy yourself.....we do!"
"Well, I have to enjoy myself.....I still feel the 'need' sometimes......since your grandad passed away.....he was a very sexual man, " said Violet.
They went to have breakfast, and had a long chat, disclosing the things they'd got up to over the years.
Violet surprised the sisters, when she told them about their grandad........besides 'normal intercourse', he'd had anal intercourse with her, which she'd enjoyed,...they'd had oral sex with each other, and it turned out they both enjoyed pee games.
"It runs in the family then," said Elsie," and have you had lesbian sex as well?"
"Yes, " she replied, " oral, kissing, everything."
"O.M.G.", said Brenda, " If only we'd known eh! "
"You mentioned pee games with grandad....what sort of games? " asked Elsie.
" Everything, you name it, " she replied, "can I be really, well...'um...bold?"
"Of course, " said Elsie.
"We did something really naughty....we tasted each others wee wee..!"
"How, tell us more, " said Brenda.
"He used my mouth as a toilet for a wee sometimes, and I did it for him as well. " she replied.
The sisters looked at each other smiling, and told Violet that they approved, and during their chat, she disclosed that she'd done the same with female friends as well.
She, to be frank, had been a bit of a whore in her life time, like the sisters........it really did run in the family then.
"So, do you fancy a bit of incest with us? " asked Elsie.
Violet thought for a moment.
" I guess so," she replied.
They returned to the lounge, and sat on the sofabed.
They were all wearing their nighties, and they all had low fronts, exposing some cleavage.
"No limits then, " said Brenda, and Violet shivered with excitement at the thought of having a naughty relationship with her granddaughters.
"But I'm so old, and wrinkly, " she said.
"So, that's no problem to us, is it," said Elsie.
She'd seen the sisters kissing, so when Brenda leant over to kiss her, she said, " I haven't got my teeth in."
This didn't bother Brenda, and she kissed Violet fully on the lips, opening her mouth, and pushing her tongue into her mouth.......she responded eagerly, and put her tongue into Brenda's mouth.
Meanwhile, Elsie had exposed Violet's breasts, and was amazed at the length of her nipples......maybe an inch, and a half long.
"Look at her fucking teats, " she said, " they're longer than ours."
"That's grandad's doing, pulling on them, sucking on them, pinching them, and of course, breast feeding your mother, " she said.
" Lets undress, " said Elsie.
They took their nighties off, and saw Violets naked body for the first time.
Indeed, she was wrinkly, across her sagging belly, and her drooping breasts, legs, arms, bottom........she had grey pubic hair, and short grey head hair.
Then as Violet was standing, her legs slightly apart, they noticed her labial lips hanging down.
"Look at her pussy flaps Elsie, " said Brenda.
They hung down, maybe three inches, and they too were wrinkly.
"Bend over Vi, let's have a look at your cunt, " said Elsie.
Violet didn't seem to be bothered that the sisters were using naughty language......she admitted she'd used it herself, and liked it too.
She bent forward, resting her hands on the sofa.
Elsie knelt down, pulled the flaps open, and began to lick the damp, sticky crease, even though she hadn't washed yet.........Elsie found the taste really nice....old urine, and some vaginal juice.
"Oh! Fuck......that's so.....Oh!....good!......I'm coming, " she cried out.
For her age, it was such a strong orgasm, but she suffered with a weak bladder, and began to leak urine, and Elsie eagerly lapped it up.
"Let me have some, " said Brenda, and Elsie got up so that she too could enjoy Violet's leak as well, and while she was running her tongue along the wet valley, she gave her pouting anus a quick rimming as well.
When she'd finished, she got up, and kissed Elsie fully on her lips, mouths open, and tongues searching, saliva flowing back,and forth.
Violet grabbed her nightie, and held it between her thighs, to stop her urine from dripping onto the carpet.
"You naughty girls," said Violet, "Oh! Dear....I'm wetting myself, " as she felt the nightie getting wet.
While she held her nightie between her legs, Elsie, and Brenda took turns in kissing her, dribbling saliva into her mouth, so that she could taste her own juices.
