Fiona and I had a one-bedroom flat, and my brother had been secretly staying with us. When the landlord found out, we were given notice to leave. We were almost certain this wasn’t allowed, but we needed a bigger place anyway, so we didn’t fight it.

With just three days remaining, we found a new place and hosted our first masturbation party with other group members, about two weeks later. Tiff, especially, couldn’t wait. She burst past Samantha and Jack towards our bedrooms.

‘Um,’ said Fiona, ‘would you like a drink first? Ryan’s bought loads.’

‘I’d like an orgasm, first. I’ve been holding off for days.’

‘Calm down,’ I told her. ‘We’ve all held off; you can wait a bit longer.’

The two bedrooms were next to each other. One contained a single and a double bed, while the other was filled with boxes, many of them still unpacked. Tiff looked back and forth between the two and slowly figured out what was going on. ‘Wait, so you still all sleep in the same room?’

We’d initially tried to split the bedrooms between us: Ryan and Fiona with the double bed in one room, and I’d have the single in the other. But I liked to watch Ryan and Fiona have sex, and I’d occasionally interact with him or indulge in funnel time with her. ‘It was easier,’ I said to Tiff, without an explanation.

She stood by the single bed, took off her top, unhooked her bra, then made to take the rest of her clothes off.

‘Well,’ said Fiona, ‘it looks like we’re starting.’ She removed her own top but hadn’t bothered with a bra, so her boobs were released immediately, just as Ryan walked in with plastic bags full of wines and beers.

‘Oh,’ he said. ‘Already?’

‘Wait, can we all at least have a drink first?’ My question was ignored as Ryan placed the bags against the wall and began to undress.

I was the last one to be naked, but it took less than five minutes before I joined the group in masturbating. That was exactly how we began every session, and the sound of the ladies’ vibrators filled the room. Sadly, the entire group couldn’t be there.

Thomas refused to join us because he disagreed with my brother and me having sex. On one hand, I understood his view, because incest isn’t exactly common. On the other hand, though, I was using contraception and we weren’t hurting anyone else in the process. Thomas had also given Steven a difficult choice: either the two boys could be a couple or Steven could continue to see the rest of the group – but not both. He reluctantly declined to join the housewarming, but he promised to talk to Thomas again.

Then there was Tiff at the other end of the scale. She wanted to know everything, asking me question after question. She also specifically wanted to watch my brother and me having sex. That would be the highlight of the night for all involved.

Changing the subject for a second, Samantha said to Ryan, ‘I hear you’ve got a job now.’

‘Yeah, I’m at Dockson’s. You know, the computer place? We’re on commission, so the more we sell the bigger the bonus. It’s so we can afford this place.’

I was prepared to cut in, because I didn’t want him to tell anyone exactly how much this place was costing us. I needn’t have worried, because Jack interrupted him instead.

‘I’m working in a gym; a mate of mine owns it. I’ve only been there three months, and I’m already running the place.’

‘Only when he’s not there,’ added Samantha.

‘Yeah, he’s hardly ever there, though. I bet you’re not a manager, Ryan.’

‘Jack, don’t be so rude.’

‘How am I being rude? I’ll tell you what else, I’m so good, the new memberships have doubled since I joined. Mate says I could sell ice to penguins.’

Not paying attention to the subject change, Tiff squealed, ‘I can’t believe I’m about to watch proper incest.’

‘Not so fast,’ said Samantha. ‘There’s something we’d like to see, first, if you’re all right doing it. You know you talked about using a funnel for your squirt.’

‘Yes, of course,’ said Fiona. ‘We’ve not shown you yet, have we?’

‘I’m onto it.’ I reached over to open the drawer with the funnel.

‘Well, I wondered,’ Samantha hesitated, ‘if you’d mind doing it into me instead. Neither of us wants to squirt, just seems a bit icky, but I really want to know how it feels.’

‘You should totally learn. I promise it’ll change your life.’

Tiff shook her head, ‘I don’t like the idea of… stuff shooting out of me. Stuff shooting into me, though, I could do that all day.’

‘Do you want it in you, then?’ asked Samantha.

‘No, you asked first.’

‘I can squirt twice. The second one’s never as big, but it’s enough.’

‘No, you need to save that for your little brother.’

‘Do you have your clit pump with you?’ asked Fiona.

‘Oh yes, I nearly forgot.’

Samantha lay on her back and I talked to her about positioning the small end of the funnel inside her. I was accustomed to Fiona, who always liked to be on her front, so I had to position myself a little differently.

Meanwhile, I kept an eye on Tiff. She rummaged in her bag and found her pump. On one end was a rubber bulb connected to a small flexible pipe. This led to a solid plastic tube just big enough for a finger, and a perfect fit to go over her clit.

‘Now,’ she said, fiddling with the connectors, ‘when I squeeze this, watch what happens.’

On the first squeeze, her clit hardly moved at all. A few more and the little head and hood slowly rose further and further up the tube.

‘Woah,’ said Fiona, with her vibrator on high speed, ‘that’s huge. Does it stay like that?’

‘No, not very long. It shrinks back, but if you keep doing it, it gets bigger.’

By this time, Samantha had the narrow end of the funnel inside her and we were both masturbating by hand, with my vagina as close to the open end as possible.

‘How long can you keep it on for?’ said Fiona to Tiff.

‘As long as I can. There’s no consensus about it.’

‘Ooh, consensus,’ mocked Jack.

It only took me two minutes to feel a build-up of my squirt. Samantha was watching my boobs bounce slightly as we both masturbated. When Fiona and I used funnels, there was an understanding it wasn’t sex but mutual masturbation. We didn’t touch each other except by accident. Instead, I looked away from Samantha, imagining my two boys were here, with both my nipples being sucked at the same time, interspersed with them kissing each other. But I could at least have one.

‘Ryan, will you…?’ and I gestured to my left nipple. Still masturbating, he leaned over and gently began to suck on it, and that did the trick. I shot my fluids into Samantha, placing myself tightly against the funnel for maximum transfer.

‘God, you can really feel it,’ she said. ‘That was amazing.’ Without waiting for me to remove the funnel, she sat up and kissed me on the lips, hitting the back of Ryan’s head with her own boob. ‘Sorry, sorry. I know you’re not gay. I shouldn’t have done that.’ She removed the funnel and wiped up.

‘It’s fine.’ That’s all I could manage before I licked the remaining juice off my own fingers. Ryan was really going at my left nipple now, so I moved him to the right one. ‘Samantha? I should have asked this ages and ages ago, but do you not mind that Tiff’s the only other one in the group who’s into women?’

‘Not at all. I have fun with her and I have fun watching everyone else.’

‘But you don’t mind Tiff doing stuff with other people? Like the boys?’

‘It makes her happy. I’ve got no problem with it.’

Tiff was removing her clit pump with one hand and pointing at Fiona and me with the other. ‘Although you two should definitely try girl-on-girl one day. No funnel, just fingers and tongue. I guarantee you’ll enjoy it.’ Her clit shrank almost to its starting position.

‘Well,’ I countered, ‘if you learn to squirt, we’ll give it some consideration.’

‘Damn. It was worth a try. Anyway, who cares? Time for incest.’

Ryan was still sucking my right nipple and still masturbating. He stopped when I leaned down and kissed him sensually on the neck.

This was so very different from when we’d first slept together. Back then, there were spoken and unspoken rules about how we interacted. Our foreplay had been solo masturbation in front of each other with minimal kissing. Penetration was always from behind to avoid eye contact and the pleasure was gained solely from imagining other people.

But now, I gently moved from his neck up to his cheek and he slowed down the strokes on his penis. I then him on the lips then slipped my tongue into his mouth.

With her vibrator back on this time, Tiff squealed, ‘You’re sister and brother.’

There had also been a time when Ryan would lose his erection on hearing ‘sister’, ‘brother’, or ‘incest’ in the heat of the moment. I remember when this changed. He’d expected to have sex with his girlfriend one day and it hadn’t happened, so he was pestering me for some action. I called him my ‘sexy little brother’ to put him off, but it seemed to make him even stiffer.

Back to the present, I pushed Ryan back onto the bed and lifted his hand off his penis, pinning down his arms. I gently placed our genitals together so he could feel my wetness but he wasn’t inside me. I then slowly kissed down his chest and stomach, making a big show of lifting up his penis. I didn’t immediately pleasure the head, instead making eye contact with him.

‘You want this in my mouth?’ For the benefit of Tiff, I added, ‘Your sister’s mouth?’

‘He hesitated as if trying to find the words. He vigorously nodded instead and I slipped the purple head into my mouth. I couldn’t be certain, but I think Tiff faintly squealed again. I definitely heard Fiona having an orgasm. She was nearly silent, but there was always a distinctive telltale grunt I’d come to recognise.

I was careful with my up-and-down strokes because I wanted his spunk in my vagina, not my mouth. I’d already decided we’d have sex face-to-face, so I let his penis go, and it was my turn to lie on my back. He received the message loud and clear, placing himself at my entrance, but not yet pushing into me. Just as I liked to make him beg for oral, he liked to pay it back for penetration.

‘I’m not sure,’ he said, ‘maybe I don’t want to.’

‘Ryan, stop your nonsense.’

‘Seriously, I can stop any time.’

‘Come on, Ryan.’ I again calculated my words to hear a reaction from Tiff. I whispered, ‘Let’s have incest.’

She whispered a quick, ‘Yes,’ and I heard her vibrator speed up as my brother pushed into me. I could tell her orgasm was going to happen soon. When Ryan leaned down to kiss me on the lips and started his thrusting, that set her off. By the time her orgasm finished, Ryan had found his rhythm.

‘It’s funny,’ she added, ‘I’ve seen you both having sex with other people before, so it kind of feels normal to see you both together.’

‘I wish he was gay,’ said Jack. ‘We’d have a lot of fun.’

‘I can’t believe I’m watching incest. Next orgasm incoming.’ I motioned for Ryan to kiss me again. As he did, he increased the impact of his thrusts. I could tell he was ready to unload.

As Tiff orgasmed, so did Ryan, leaving his spunk deep inside me. We kissed again, and he slowly withdrew. I collected some of it. On seeing this, Jack orgasmed. I was able to mix the boys’ spunk together and swallow it all.

‘That was better than I could have hoped for,’ said Tiff. ‘It’s weird if you think about it, but it’s not weird seeing it. We totally need Thomas and Steven back, though.’ The others gave nods of approval.

I kissed my brother briefly. ‘I need a drink. We all need a drink. I’m exhausted already.’

‘I’m not. I’m not nearly finished. You don’t mind if I and Samantha have sex, do you?’

‘Not at all,’ said Ryan. ‘As long as we can watch.’

‘Of course,’ said Samantha. She dropped her voice to a whisper, ‘And I’ve still got a bit of your sister’s juice inside me.’
