We wasted no time in taking each other’s clothes off before I led my boyfriend and my swimming buddy to the bedroom. I was more than ready to help out with whatever they wanted to do together. Now I was holding Aidan’s penis in one hand, checking the condom was rolled right down to the base. He was on top of Matt, whose vagina I was holding open with the other hand. Just as I was preparing to guide Aidan inside, I hesitat...

I hadn’t seen Aidan all week. He was becoming so popular on the comedy circuit that he had three separate paid gigs on top of his usual work. Meanwhile, I was busy catching up with overdue coursework. On Saturday, we agreed to meet up and do something relaxing together, but I had just enough time for a quick swim first. I limited myself to thirty minutes. As I was climbing out of the pool, a couple of friends from the swi...

A few days after I introduced Aidan to Matt, I was still embarrassed about a little faux pas. Whenever I was naked with Matt in the changing room and nobody else was around, I would lean in and joke, ‘Nice penis,’ in a theatrical whisper. He would roll back his foreskin to reveal his small purple head and say, ‘Thanks, I grew it myself.’ Then I absentmindedly said it while we were drying off with Matt. The moment it was o...

For someone who hated gym class in school, I’d developed a surprising affinity for swimming during my first year at university. Entering my second year after the summer break, I stopped by the campus pool, eager to step back into the water. My return coincided with the end of a major overhaul of the locker rooms. I only had to follow the smell of fresh paint and traces of sawdust. As anticipated, it was much larger. Brand...

With university finally at an end, Jack had arranged a special masturbation session for the group. For one evening only, we would have exclusive use of the gym where he worked. As soon as we were inside, he locked the doors behind us. ‘This is the reception desk, staff room there.’ He led us around a corner. ‘Weight machines, a few treadmills. I’ve set up all the adjustable benches and there’s a load of towels at the back...

Over the years, the members of our masturbation group had interacted sexually in all sorts of combinations. One-on-one sex happened every time we met, threesomes were relatively common, and everyone had watched everyone else masturbate and have sex. But some members had never been together before. Apparently, on a whim, Tiff suggested to Samantha that she and Thomas should try having sex. It was a suggestion she immediate...

When Thomas found out I’d been having sex with my brother, he didn’t want anything to do with our masturbation group. Steven had also reluctantly stayed away because Thomas had made him choose between him or us. At Fiona’s suggestion, it was time to pay the boys a surprise visit and find out whether we could make amends. The rest of the group were enthusiastic and wanted to come along, although Tiff had to work. Normally...

Ryan and I were waiting for our older sister. She was working in the area and had invited herself to stay with us overnight, telling us she’d arrive by 6 pm. By 9:30 pm, she still hadn’t shown up and wasn’t answering her phone. I didn’t bother leaving a voicemail. I felt the ten missed calls already sent out a clear enough message. I accidentally let out a grunt of frustration. ‘No luck with Rachel?’ asked Fiona. ‘Nope,’...

In our new flat, it was difficult to find the optimal arrangement of beds in our shared bedroom. We settled upon a single and a double bed next to each other, with a narrow passageway between them. I would sleep in the single and Fiona liked the far side of the double, so my brother would be between us. Although we would interact with each other sexually, there were times we would simply watch each other masturbate. Ryan...

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....

‘We’ve been going over this for ages,’ I said. ‘Yes, he’s my brother; yes, we’re unusually close.’ Everyone was in the boys’ living room, either naked or in underwear, but Thomas had put all his clothes back on. ‘You’re not just close. You have full sex with your own little brother. He gives you orgasms, he puts his sperm in you.’ ‘It hardly ever happens. Most of the time we just masturbate together. It’s only if we’re bo...

‘Are you enjoying yourself?’ I asked Ryan. ‘Yes.’ ‘That’s about the tenth time,’ said Fiona. ‘Leave him alone.’ All of us were masturbating with Steven and Thomas in their new place, and this was the first time Ryan had joined us. It had taken a long time for the boys to arrange their housewarming, so it was great to see them again. We were also supposed to have Tiff, Samantha and Jack. They were driving, but they’d calle...

My brother had come to visit for the weekend. After our meal, he squeezed onto the small couch between my flatmate and me, with his arm around her. She was subtly flirting back. Us ladies shared a bedroom, and later that evening, he would be sleeping on an inflatable mattress between our single beds. Ryan and Fiona weren’t a couple, but they’d had sex a few times. I'd already said I didn't mind them doing whatever they wa...

At around four o'clock, I met my little brother at the railway station. I checked around me, and when I was reasonably sure there was nobody we knew, I took a calculated risk and kissed him quickly on the lips, which turned me on. The first question out of his mouth was, 'Where's Fiona?' 'Ryan! Not even a "How are you?"' 'How are you? Where's Fiona?' 'You're a cheeky boy, aren't you?' I helped him with one of his bags as...

Fiona and I had moved into our own place, and we'd invited the rest of our masturbation group to the housewarming. The previous night had been the most raucous session yet, with threesomes, strap-ons, and spankings. We'd all tired ourselves out and gone to bed early. But in the morning, we were up and masturbating again, and Tiff wanted to make the most of her time. She asked if it would be all right to borrow Steven and...
