It had been six months since Ian had sex with his best friend Nick and his wife, then his daughter, then his brother, then his two nieces, then his nephew, then his mother and father-in-law, then his two brothers-in-law.
Yes, it had been a busy few months of rampant fucking. He'd been introduced to the delights of having a cock up his arse and his cock up other people's arses, had swallowed more mouthfuls of spunk than he could count, whether directly from a cock, licking it off somebody's face or body, or sucking it out of a cunt, and had shared it with men and women alike.
On one memorable occasion, Rachel had taken him to a swingers party. They didn't allow single men to turn up on their own, so Rachel had stood in as his partner, what with him not having one of his own, while Nick had stayed at home and amused himself in other ways. There, he'd met Charlotte. The reason it was so memorable was because Charlotte had taken ten loads of spunk over her body and wanted someone to fuck her. Ian had volunteered. The feel of fucking an attractive, youngish, she was thirty nine to his forty two, woman while the spunk of ten men oozed between their bodies was incredible. It wasn't always easy to stay connected as their bodies became more and more slippery, and they had burst out into fits of giggles on several occasions. Eventually, he came inside her, and they'd lain for quite a while, basking in the afterglow as the spunk dried on their bodies. A few of the men had even recovered and had wanked themselves off over both their faces.
Since then, Charlotte had moved into his house. Ian had told her about his adventures with Nick and Rachel but hadn't mentioned what he got up to with the other family members. He wasn't sure how she'd react to such a revelation. She knew he was bisexual and had absolutely no problem with it, being bi herself. Indeed, Charlotte had a wide circle of friends she regularly had sex with, nearly all of whom were bisexual like themselves, and saw no reason to give this up just because she was in a relationship. Ian was more than okay with this, as he got to join in occasionally. Why would he have a problem gaining access to more cocks and cunts?
Nick and Rachel had visited them on a few occasions, and they'd indulged in foursomes. They too didn't feel comfortable telling her about the other family members.
For now, Charlotte would go off and fuck various of her friends, either with or without Ian, while he would visit Nick for fun and games with his family.
All this was about to change.
Ian had been away with work for a getaway for a few days. He was supposed to be back tomorrow, but they'd finished a day early. Rather than contact Charlotte to let her know, he decided to surprise her.
He unlocked the door and stepped inside, to be greeted with the sound of moaning coming from upstairs. Suspecting she was with one of her many lovers, he undressed and crept up the stairs. This had happened quite a few times over the last few months and Charlotte was always willing to take on an extra cock, just as Ian was always willing to get some cunt and cock action.
He listened outside the closed bedroom door for a few minutes listening to Charlotte moaning and urging whoever she was with to ram their cock deeper.
Unable to resist anymore, he opened the door and stepped inside.
Charlotte was up on all fours on the bed, being fucked from behind by.... Her brother, Oliver.
Ian stood, mouth agape, and cock wilting slightly, as he took in the sight.
"Oh shit," Oliver said, at about the same time as Charlotte said the same thing.
Ian recovered quickly, his cock once more attaining full erection. "Don't mind me," he said, as he climbed onto the bed and thrust his cock at Charlotte's mouth. Her mouth opened of its own accord and Ian pushed forward until her nose met his pubes.
"How you doing Olly?" Ian asked.
"Erm, okay, I suppose," he replied, looking a bit embarrassed.
"Can't help noticing that you're fucking your sister."
"Yeah, suppose I am. But can you blame me? You've fucked her, you know how lush she is."
Ian laughed. "Yeah, don't I just."
"I'm right here you know," Charlotte said, removing Ian's cock from her mouth. "Less talk, more action," she said as she took Ian's cock into her mouth once more.
They kept this up for a good few minutes, until Oliver started breathing heavily and moving faster as he got ready to come.
"Shoot inside her," Ian said. "Then I'll have some sloppy seconds," he continued.
That set Olive off and he unloaded his balls into his sister's cunt. Once emptied, he withdrew, and Ian got a first look at his cock. Very nice, eight inches or so and quite fat, and shining with his spunk and his sister's cunt juices. He looked forward to getting it into his mouth at some point, as long as Oliver was willing, of course.
Charlotte turned onto her back, holding her hand over her cunt so that nothing leaked out. She spread her legs and used both hands to open her cunt.
Ian got onto the bed and maneuvered himself until his cock was at her entrance. He rubbed it along her slit, gathering up some of the leakage, before plunging into her to the hilt. Some of Olly's spunk trickled out and coated Ian's shaft. He began to move in and out, steadily increasing speed, as more and more of Olly's cum was whipped into a froth around the base of his cock.
Charlotte grabbed his arse and forced him deeper inside her, until a huge orgasm tore through her. She ran her hands over her tits, pushing them together, which gave Ian an idea.
He pulled out and straddled her, then pushed his cock in between her tits, and started to slide back and forth, Olly's spunk and his own pre-cum providing more than adequate lubrication. Before too long, he was ready, and a wad of spunk shot out of his cock and hit Charlotte's chin. He quickly knelt up and aimed the next eruptions at her mouth, which she opened eagerly.
"Fucking hell!" Oliver exclaimed, as he looked on keenly, his hand wrapped around his now recovered cock. He couldn't resist and pointed his cock at Charlotte's mouth and erupted. It wasn't a huge load, unsurprisingly, but Charlotte accepted it readily. As did Ian, who clamped his mouth over Charlotte's and shared in the creamy goodness. Oliver pushed his cock between their lips so they could clean him off, savouring the feel of two tongues swirling around his knob. It seemed that Oliver was more than willing to have his cock sucked by another man, which opened up all sorts of possibilities for the future, Ian thought.
After Oliver had left, with no further discussion of the situation, Charlotte lay next to Ian, running her fingers over his chest.
"I've got a bit of a confession," Ian said, after a few minutes.
"Oh? Sounds ominous," Charlotte said.
