Harry was very sad, very sad and incredibly horny. He had been incredibly horny every day for the last eighteen months since Mary his devoted wife had passed away. Over fifty years of happy marriage had ended quite suddenly leaving a huge emotional void in his life, also it had robbed him of a ready outlet for his sexual needs.
They had met as eighteen year old school sixth formers, he had fucked her twice on their first date, not because she was some easy lay but because they had immediately clicked and couldn't keep their hands off each other. Not least of the reasons they seemed made for each other was that she was the best looking girl in the school with fantastic tits and he had the biggest cock, a proud ten inches when fully erect and too thick even for his own shovel hands to fully encircle. She was no virgin of course, she had seen a few cocks and sampled three others which simply confirmed that Harry's was the one for her.
Harry was the only son of a very successful businessman so his financial future was secure, removing any obstacle to their early marriage. During which their sex life had been full to the brim. Despite their unswerving attraction to each other, they had been active in the swinging scene of the 1970's and 80's, both of them being extremely popular for obvious reasons. They also enjoyed experimenting in every aspect of sex, particularly enjoying getting involved in the whole BDSM scene. Despite their very active participation, they still managed to raise two daughters who grew up blissfully unaware of their parents activities.
Once the children had married and left, Mary and Harry were able to immerse themselves fully into the world of sex. Mary still had her figure, her tits now even larger but still without any sag due to frequent visits to the gym, Harry of course was always in demand with his cunt stretching cock. As their relationship developed, Mary made it obvious that she enjoyed their role plays when she took on the role of a slut who needed to be dominated and controlled.
Developing from this, Harry soon decided to introduce her to the dogging scene, he had always enjoyed watching her with other men and women at their swinging parties, but now came the added thrill of watching her being used as a cum slut by complete strangers. Mary took to the scene with enthusiasm initially loving the experience of complete strangers wanking off over her face and tits, but soon she moved on to letting these strangers have full use of her cunt and arsehole, as long as they agreed to use a condom.
Consequently the one emotion he had never experience throughout their marriage was sexual frustration, quite simply, if he wanted her he fucked her, anywhere, anytime, likewise she was always ready for him, loving the knowledge that even in her sixties he found her the sexiest woman on the planet.
So there we were, seventy year old Harry now without his lifelong sexual outlet, sat in his armchair slowly stroking his erection as he watched some unknown middle age woman getting fucked in her cunt and arse on the internet. Harry didn't particularly find porn stimulating, Mary and him had often watched it but for Harry it was a poor substitute, he didn't need fresh ideas from the Internet when he had a wife who never saw any barriers to sexual activity. Even now he found more stimulation imagining his beloved wife knelt before him waiting to take his spunk into her mouth than he was getting from his computer screen.
Harry closed his eyes, imagining the moans of encouragement coming from his computer were actually Mary urging him on, begging for him to fill her mouth with his seed, Harry could feel the surge beginning in the depths of his balls, he slowed his strokes wanting to prolong the build-up, he was completely lost in his wonderful fantasy.
"Do you want help with that?"
Harry's eyes opened wide with shock, the screen of his computer reflecting the sight of Rachel his eldest daughter standing in the doorway.
"Oh my god, oh my god!" Harry made a desperate effort to cover himself, trying to switch off the computer at the same time. Panicking, managing to do neither effectively "it's not Wednesday, lt's not Wednesday!" He almost fell as he tried to stand and pull up his trousers, falling back into the chair, his turgid cock still standing proud as he tried to conceal it in his underpants.
"Calm down Dad, calm down!"
"But it's not Wednesday!"
Rachel came around to face him, helping him replace his trousers to cover some of his embarrassment, quite unsuccessfully as the large lump in his underpants was still in plain view.
"I told you on Sunday that it would be Tuesday this week, the girls have a school concert tomorrow, now calm down, it's not a problem."
Rachel always called in on a Wednesday to pick up his laundry and shopping list.
As Harry calmed, still trying to restore his clothing to decency,
"l'm sorry, l don't know what to say, you must think l'm some old pervert."
"Shush Dad." Rachel knelt in front of him, holding his hand to reassure him, "it's not a problem honestly, l know it's been hard for you with Mum gone, l know how active you both were, Mum told me all about your life together the last few months before she died. She made me promise to help you when your frustration got too much, she even suggested l arrange a women to visit you to help you out."
