Matty, amidst greeting old friends and lugging sleeping bags and holdalls up the stairs, caught sight of Nina smoking a cigarette, and hoped she wasn't going to be too much of a wet blanket on the weekend. Sure, she was Liz's mate, and sure, she was an ok sort of girl most of the time, but somehow he couldn't picture her as the demon drummer she'd apparently been a year or so back. She'd dropped out of the team because that prat of a bloke hadn't thought it was cool enough, so Liz said, but Matty wasn't sure
that bringing her back to a weekend festival like this one was going to work a miracle cure. He shrugged as he reached the top of the staircase, thinking that there wasn't much he could do about Nina either way. He made his way into the tower room he'd been told was the designated crashing spot, and dumped his armful of baggage in the corner Liz had earmarked - just far enough into a little alcove to give them some privacy later. Privacy he'd definitely make use of once other people were asleep... Matty grinned to himself, anticipating how good it would be to screw Liz in the middle of a room full of people, both of them finding that the battle to do it as quietly as possible added an extra edge to what was always good hot sex anyway. He remembered them doing it at the Mayday fair earlier in the year: about eighteen pissed Morris dancers snoring their heads off in this church hall and him and Liz in one sleeping bag, moving slowly and carefully, groin to groin, clasping each other tightly and grinning against each other's mouths in the darkness. Her legs had parted and he'd been able to feel how wet and ready she was, her pussy hot and open against his
thigh. A little careful wriggling, raising himself slightly as she opened her legs further, and he'd been able to slide his way in, slow and steady, hearing her breathing hoarsen once he was in position to start pumping, regular strokes, feeling her pussy walls clench and unclench around him, and both of them kissing, tongues entwined, making sure they swallowed any groans or cries so no one else would hear them. Matty spread the sleeping bags out and dug the bottle of bitter out of the other holdall. By the sounds filtering up the staircase, the get-to-know-you party was getting started downstairs.

Nina sprawled across her sleeping bag, giggling as she reached for her holdall and rummaged inside it for the plunge-necked red top she'd packed against her better judgement. She'd thought she was in for a couple of passable but dull days with people she'd mostly outgrown, and that the last thing she'd need was any pulling gear but now, at the end of an exhilarating day with the barbecue party ahead, she felt better than she had done in months. Of course the initial plan as expressed by Liz had been for
Nina just to watch the parade and performances but oh, surprise surprise, at the second pub they stopped at, someone had produced a spare drum and loudly required a pair of hands to play it. Nina had volunteered before she even knew she was going to, having found that every single rhythm and pattern she'd learned when she was part of Liz's team had stayed with her. Her fingers had been itching to play from the start of the parade, and falling into line behind Liz and the girls had felt so utterly natural she hadn't even bothered to ask herself why she'd given this up. And all day the five different drumming teams had moved between pubs in the old country town, putting on a show outside each one, grabbing a few drinks, playing some more, moving on, parading. All around her was noise and excitement, the raw pounding power of the drums, the cheers from the crowds she couldn't remember the last time she'd had so much fun. She peeled off her team t-shirt and donned the red top, fluffed up her
short dark hair with her fingers and started to apply a bit of make-up. Even if there was no particular Mr Wonderful here tonight, she was going to party.

Liz, sipping white wine from a pint mug, watched the whirling dancers in the castle's main hall, and thought again how right she'd been to persuade Nina to come along. Her friend was right in the middle of the dance floor, spinning madly and laughing at the top of her voice while the band, a bunch of locals doing old rock'n'roll songs, stepped the pace up even more. LIz herself had been dancing earlier, but now she was sufficiently out of breath to prefer just sitting and watching. She had enjoyed the day as well: like Nina, she found the drumming made her feel spectacularly good and now, with a few drinks inside her, healthy tiredness in her limbs and good friends all around, she felt terrific. Matty came up behind her, put his arms round her and kissed the back of her
neck.
"Tired, doll?" he asked.
Liz shook her head. "Well, a bit, I suppose. Just chilling out. Where have you been?"
"I went outside. There's a full moon and tons of stars, it's fucking gorgeous. Want to come and have a look?"
She let him take her by the hand and lead her outside, quite well aware that she'd be seeing some kind of stars soon. It was a mild night for the time of year, and the castle grounds did look gorgeous by moonlight. They wandered round for several minutes before coming to a stone arch and part of a ruined wall, surrounded by trees, some distance away from the castle itself.
"Wonder what this was for?" LIz murmured, not really caring. She knew Matty would have a use for it. He took the glass of wine from her, sipped it and handed it back.
"Chapel or storehouse or something. Don't know. But it is nice and private, doll..."
They stepped through the arch and moved into the corner made by the crumbling wall. There was no rubble in the long grass, and it didn't look as though any more chunks of masonry were going to fall on them, so Liz wasn't worried when Matty pushed her
gently against the stonework and began to kiss her greedily, his hands sliding up underneath her jumper to stroke her breasts through her thin lacy bra. Reaching out, she put her glass on a convenient ledge so that both her hands were free and she could mimic his gestures, freeing his shirt from his jeans and running her palms over his smooth chest, feeling his nipples harden under her touch. He'd undone her bra now and bared her breasts, her jumper right up around her neck, so she let go of him for a moment and pulled it off, not minding the chill evening air. Matty bent his head and started to suck on her nipples, almost biting them, and Liz heard herself whimpering in pleasure. She reached for his crotch, cupping his cock through his clothing and finding it hard and erect, and it was his turn to moan when she gently squeezed it. Liz knew she was wet, could feel the moisture in her pussy gathering, her labia hot and sticky, more than ready. She pushed herself against Matty as he raised his head, grinding her groin into his, rubbing herself against the rigid swelling of his hard on. He fumbled with the button of her trousers, got it undone and tugged them down to her knees, taking her panties with them while she did the same for him, and then she bent her knees and parted her thighs and pulled him in close, letting his cock find its way into her wet, eager slit, bracing herself against the wall and
holding him tightly as he began to fuck her with short, powerful thrusts, gripping her hips and pushing up into her, nipping her neck and telling her how good it felt to be inside her. He'd got one hand in between their bodies now, finding her clit and rubbing it
steadily, and Liz dug her nails into his back and came with a long gasping cry. Matty fucked harder, clutching her to him, and then he shuddered and dropped his head down on her shoulder, and she felt the warm stickiness of his spunk filling her pussy. "Makes a change not having to be quiet," she murmured, and he gently bit her ear.
"We'll save that one for later," he said.

The party was drawing to a close, those who lived nearby or who had booked in to guest houses had mostly departed, and a lot of the people roughing it in the castle's tower rooms had decamped for their sleeping bags. Nina sat on a folding picnic chair near the fireplace, enjoying a conversation that was becoming progressively more outrageous. Her new friends were Carolyn, a petite blonde with a wicked laugh and a husband called Jim, who was equally blonde, tanned and well-muscled, and Jim's friend Alan,
stocky and red-haired, with piercing grey eyes. He evidently liked Nina more than on a simply social level; he'd earlier told her that seeing her drum with Liz's team four years ago had got him interested in joining a team on his own account.
"Anyway," Carolyn was saying now, "I asked the bloody woman who the survey was for and she said this magazine I'd never heard of, and was I straight, gay or bisexual, and I said I was trisexual -"
"As in, try anything once," said Jim, and Carolyn dug him in the ribs.
"Don't nick my punchlines, you, or I'll make you sleep on the grass." Everyone laughed, and the last bottle of red wine did the rounds again. Nina was almost surprised to realise that she was pleasantly horny; not dripping wet, but warm-feeling, tingling all over. She knew something was coming, and was beginning to suspect what it might be. They'd moved on from general discussions of sexual practice to the more specific, and it was pretty clear that Jim and Carolyn's marriage was, if not open, definitely ajar and very happily so. Nina had read and heard about swinging, usually with a guilty little thrill, but she had never
thought it was the kind of thing she might actually participate in. Looking from face to face and seeing a similar anticipation in their eyes to what she was feeling herself made her shiver, and she could feel her clitoris beginning to throb with arousal.
"Have you seen our camper van?" Jim asked her suddenly. "It's pretty spectacular. Better than kipping up there with the spiders - "
"And the snorers, and the farters," Carolyn interrupted. She smiled mischievously at Nina and said, "Would you like to come and have a look at the passion wagon, then?"

Outside the sky had clouded over a little, but it was still relatively warm. Jim and Carolyn's van was a smart, substantial camper, painted red and green and clearly quite new. Inside, there was a small kitchen area and two couches, one of which was folded down to do duty as a double bed. "Coffee, anyone?" Jim enquired, and Alan laughed, putting his arm round Nina's shoulders and gently massaging the side of her breast.
"I think we might want some a bit later," he said. "All right, Nina?" Nodding her head, Nina understood that she was agreeing to more than just the deferral of coffee, and she didn't mind a bit. Alan drew her down on the bed and began to kiss her, as Carolyn began to undress, posing for Jim who had sat down on the other side of the bed. Once she was down to her skimpy blue panties, her firm little tits not seeming to need a bra, Carolyn joined them all with affectionate caresses: stroking Alan's hair with one hand as she unfastened Jim's shirt with the other, kissing Nina's cheek and whispering "Relax, it will be fine," as she did so. Nina had expected to feel nervous, but the others' calm enjoyment of the situation put her at her ease, and she soon found herself stroking and teasing Carolyn's breasts while Alan and Jim undressed her slowly, kissing each area of skin they bared. She wasn't sure
whose fingers were the first to probe into the wet heat of her quim, but she knew it was Carolyn who was licking her nipples when they eased her onto her back. Now she was between Alan and Jim, in a position to play with each of their hard, excited cocks, so she took one in each hand and began to stroke and squeeze them as Carolyn kissed her way down Nina's belly and blew softly on the fluff of hair that covered her pussy. Alan had managed to manoeuvre himself into the right position to stroke and finger Carolyn's cunt as she started licking Nina out in real earnest and Nina, working on the two cocks and feeling warm ripples of pleasure spread through her, wondered for a tiny moment what she'd ever seen in boring old Ken. Carolyn was working on her
with fingers and tongue now, and Nina couldn't hold back any longer: she arched her back and came. They were all close round her then, hugging and kissing her, and then Jim had gathered Carolyn up in his arms, rolled her over and mounted her, his cock clearly driving straight into a very excited and ready honey-pot. Nina looked down at Alan's rearing prick, a slender but lengthy tool, and licked her lips. Bending over, she kissed the tip and then opened her mouth and took as much of the length as she could. Alan moaned, ruffling her hair and groping her tits as she sucked him hard and happily.
"I want to fuck you, do you want that," he murmured after a minute or two, and Nina, her sopping quim more than ready to be filled, lifted her head and flung herself languidly backwards, opening her legs and tickling her own clitty as he got on top of her, holding
his cock firmly and guiding it in with a wonderful teasing slowness. Soon enough, though, he was in her, that lovely long supple cock twisting inside her as he swivelled his hips. Carolyn flung out one hand and gave Nina's nipple a friendly tweak, and Nina returned the gesture, trailing her fingers down Jim's spine for good measure. They were all fucking hard now, matching each other stroke for stroke and cry for cry. Nina could feel something building, some spectacular rising force in her body and mind, and she knew that when she came again it was going to feel like an earthquake. Carolyn, beside her, gave a long wailing groan, and grabbed her hand, and Nina felt the bed shaking, her own body shuddering, the warmth of Carolyn's body tensing beside her and the throbbing strength of Alan's cock in her cunt, and then the orgasm came over her like a tidal wave, flashing lights behind her closed eyes, the shouts and groans of the others, the awesome realisation that every one of them was coming just as hard as she was, and then a slow, shimmering sense of release.
"That... that was pretty awesome," Alan said a few minutes later. "We all popped at once, didn't we?" No one contradicted him, but Nina couldn't help laughing at Carolyn's verdict.
