'Turn around, Beth,' Matthew said. 'Let them see your bottom.'
Beth did as she was told. Suddenly, on a girlish whim, she wiggled it at us. Immediately Matthew gave her a smart smack across her rump. Beth squealed.
'You see how I must keep constant vigilance against the appearance of her inner slut,' Matthew said, adopting a mock-serious tone of censoriousness.
Pilar laughed. 'Perhaps some further correction may be required tomorrow,' she said, her eyes sparkling. 'Aidan is rather good at that.'
'I am very pleased to hear it,' Matthew said.
He told Beth to let her skirt down. Soon we said goodnight, going our separate ways but making arrangements to meet the next day at the hotel where Aidan and Pilar were staying. Beth was rather quiet when we got her home. I suppose it was quite a big step for her, being given as a plaything to two people she had only just met.
We took her to the hotel right after lunch. Beth was in a summer dress, in a pretty patterned cotton, quite short, to show off her good legs, and buttoning down to the waist. I had bought her some underwear especially for the occasion, a bra and thong in grey satin. In the taxi on the way over she looked a little preoccupied. Matthew held her hand and whispered words of encouragement. At one point he put his hand on her knee and moved it slowly up her skirt. He often did things like this in taxis, enjoying the slight sense of danger, the possibility of being observed. He knew that Beth found it embarrassing; she constantly glanced at the driver's mirror, trying to work out just what he could see on the back seat. At one point she tried to pull her dress down, and Matthew slapped her hand, as if to say, 'I decide how much leg you show, young lady!'
When we got to the hotel, Aidan and Pilar joined us in the lobby. We didn't stay long. The plan was that we would leave Beth with them for the whole afternoon, returning at about five to collect her. Matthew and I kissed her goodbye.
'Remember, Beth,' said Matthew, 'that anything Aidan wishes to do is in accordance with my wishes too.'
'OK,' she said, looking a bit nervous.
Later Beth gave Matthew and me a full account of her afternoon. It began with Pilar taking her into the bar. Aidan went upstairs; he had a couple of calls to make, but I think the idea was that Pilar should have a little time on her own with Beth, to put her in a relaxed and receptive mood before taking her upstairs to Aidan. So the two of them sat down with a couple of drinks. Pilar apparently told Beth a few details of what Aidan and she liked to do together; how he liked to spank her, with which implements, how he put her in the mood for it, what he made her do after a spanking. Beth said she was getting quite horny listening to this. After half an hour or so Pilar said they should go upstairs. Aidan and Pilar had a suite; Aidan was seated in an armchair by the window. Pilar took a seat on the sofa, leaving Beth standing in the middle of the room.
'Come here, Beth,' said Aidan.
She crossed the room and stood looking down at him.
'Are you going to be a good girl?' Aidan said.
'Yes,' Beth said.
'Yes, sir,' Aidan corrected her.
'Yes, sir,' Beth repeated.
'And you will do as I ask you?'
'Yes, sir. I'll try. I hope it isn't anything too difficult.'
Aidan pulled her down across his knee. He hitched up her dress, looked at her bottom for a while, then pulled down her knickers. He stroked her bottom slowly.
'She's got a nice ass, don't you think?' he asked Pilar.
'Lovely,' Pilar agreed. I can't help wondering how she felt, watching her man touch another girl in this intimate manner. Of course I had been doing exactly the same thing for months, watching Matthew with her, which is why I was aware of the conflicts it set up. I was always sexually excited by seeing Matthew with Beth. I enjoyed him doing the things he did to her, but it would be foolish to deny there was a twinge of jealousy. On the other hand, I know from talking to Pilar, both before this event and subsequently, that she loves her husband and delights in pleasing him. To give him a birthday present of a pretty girl was an act of great generosity on her part. I remember now that she had done something like it once before. They had been in Las Vegas and Pilar had hired a hooker for Aidan, and watched while he fucked her. This, however, was a little different. Aidan wasn't going to have an affair with Beth, but there was much more emotional contact, it was a far more personal thing than a transaction with a paid professional. But I am sure that having made the decision, Pilar was determined not to spoil the fun by expressing any negative feelings.
Aidan raised his hand and brought it down sharply on Beth's behind. She gave a little cry, perhaps more from surprise than because it stung. Nevertheless, as Aidan's hand rose and fell, Beth's bottom began to grow pink, and then a darker shade. It didn't seem as if Aidan was exerting maximum force, but Beth was wriggling around, meaning he had to use one hand to hold her still.
Aidan stopped spanking. There was silence except for Beth's heavy breathing.
'Stand up,' Aidan said.
Beth got to her feet.
'Pilar, will you undress her for me?'
Pilar was happy to oblige. I think, from talking to her subsequently, that she's not really bisexual, but she got enjoyment from dominating another girl under the direction of Aidan. It was exciting to her to feel Beth under the control of both of them. And once Beth was naked she would be even more submissive, Pilar felt sure.
Pilar removed all Beth's clothes. Aidan put his hand on the back of Beth's neck and pushed her down over the arm of the sofa so that her face was buried in the cushions.
'Will you fetch my tawse for me, Pilar?'
I remember Pilar telling me that Aidan had what she called a 'particularly nasty weapon', a leather tawse which had been given him by another dom. Pilar said she hated it; the tawse delivered a really painful, stinging blow, and she said Aidan took a sadistic delight in seeing how much it made a girl squeal and hop around. Doubtless Pilar was glad that this time she was not to be the recipient.
'Hold her hands,' Aidan said to Pilar after she had given him the tawse.
Pilar sat on the sofa and took Beth's hands firmly in hers. She bent and kissed Beth on the cheek. Aidan stood and measured the distance. He raised his arm and brought it down accurately on the centre of Beth's bottom.
'Jeez!' exclaimed Beth. It was a lot harder than she was expecting. Pilar could feel her trying to get her hands free, doubtless so she could rub her bottom, but Pilar held her firm. Aidan raised his arm again. The tawse smacked against Beth's buttocks. Already there were red marks on top of the pinkness from the handspanking. Beth yelped and tried to wriggle free, but Aidan was relentless, spanking her with the tawse perhaps a score of times. At last he set it down.
'That was just to get you warmed up and in the mood,' he said. 'Are you ready to please me now?'
'Yes, sir,' Beth said quietly.
'Bring her over here,' Aidan said, sitting back down in his chair. Pilar got Beth to her feet and led her across.
'On her knees,' Aidan said.
Pilar pushed Beth down between Aidan's outstretched legs.
'You know what I want,' Aidan said to Pilar.
'Of course,' she said. She unzipped him, reached inside and took out his cock. It was hard already. Beth told me later it was a very nice cock, quite long and thick. Pilar pushed Beth's head down.
'Suck sir's cock, like a good girl,' Pilar said. She pressed her hand on the back of Beth's neck as Beth went to work. Matthew had trained her to be a pretty skilled cock-sucker by this time. Of course each man likes it differently, some slow and sensual, some hard and fast. Pilar knew exactly what Aidan's pleasure was, and in a quiet but firm voice gave Beth instructions: lick here, suck there, just a little faster, now kiss his balls, and so forth. There's no doubt Pilar derived great pleasure from directing this pretty girl to give her husband service. As she said to me later, maybe there was a twinge or two of jealousy, but at least it was all done right under my nose, not behind my back, and I had a hand in it. And I got pleasure from knowing I was giving him such a lovely gift.'
Aidan got to his feet and began to push his cock more forcefully into Beth's mouth, right to the back of her throat. She was half choking. He pulled it part-way back out, and then thrust it back in, even harder.
'Good girl,' he said.
Beth did her best to take his whole cock into her mouth. Pilar watched approvingly. Aidan pulled his cock out.
'Fetch her collar now,' he said to Pilar.
Pilar went into the bedroom and came back out with a pink leather dog-collar. It was decorated with rhinestone studs. Aidan held it up to Beth as she knelt on the floor.
'Have you been collared, little girl?' he asked.
'No, sir,' she said. It was true. Though Matthew had bought her a collar, he'd never in fact used it.
'Very well,' said Aidan. 'It's time you were. Nothing like a collar to ensure good behaviour.'
He showed Beth that the collar had a dog-tag attached; on it was engraved Beth's name and the words 'owned by Annabel and Matthew'. Beth was thrilled by this. Aidan buckled the collar round Beth's neck. Pilar then handed him a matching leash; he fastened it to the collar and gave it a tug, pulling Beth's head up.
He handed the leash back to Pilar. 'Take her for a walk,' he said.
Pilar led Beth round the room on her knees, occasionally tugging hard on the leash to hurry her along. Pilar brought her back to where Aidan had seated himself. His cock was still exposed and erect.
'Round again,' Aidan said. He ordered a third circuit of the room before taking the leash from Pilar and pulling Beth behind him into the bedroom, Pilar following. He put Beth up on the bed, kneeling, her ass facing outwards.
'I'm going to fuck you now, little girl,' he said. 'Your owner has given you to me to do as I like with, and it pleases me to sink my cock into you. After I've done this we'll play a few more games.'
'Yes, sir,' said Beth. She turned her head and watched as Pilar put a condom on Aidan's cock and guided his cock to the opening of Beth's cunt. Aidan pushed himself in slowly, Beth grunting as she felt the cock go in deep. Once he was in all the way, Aidan held himself still for a moment, then began to thrust into Beth in a regular rhythm. Pilar went and sat beside Beth, holding her face in her hands, kissing her.
'He's getting so much pleasure from this,' Pilar whispered to her. 'I like him to have what he wants.'
Aidan fucked Beth steadily, finally ejaculating in her. He pulled out and slipped off the condom.
'You're a sweet little girl, with a lovely cunt,' he said. 'Very good to fuck.'
Aidan had Beth lie on the bed, with Pilar between them.
'What do you think of Pilar?' Aidan asked Beth.
'She's lovely,' Beth said. She stroked Pilar's breasts.
'Does your owner ever fuck you in the ass?' Aidan asked her.
'Yes, sir, he has done. But not often.' Beth looked wistful for a moment. 'Actually he doesn't fuck me all that often, in any way. It's mostly discipline. And I get to masturbate on his instructions.'
'I see,' said Aidan. 'I fuck Pilar a lot. Don't I?' he asked her.
'Yes, you do,' said Pilar, smiling at the thought.
'I like to fuck her in the ass,' Aidan said. 'I like to keep her in training for that.'
'How do you do that?' Beth asked.
Aidan got off the bed, went over to a suitcase and came back with a large black butt-plug.
'Do you know what this is?'
Beth looked at it curiously. 'It's to go in the bottom?"
'That's right. Would you like to put it in for her?'
Pilar began to blush. She looked at Aidan as if she wished he wouldn't order that, but he had clearly made up his mind. He'd also brought over some lubricant.
'I don't think I know how,' Beth said dubiously.
'There's no great trick to it,' Aidan said. 'First put lots of lube into her ass.'
Pilar was blushing more than ever. Aidan pushed her onto her tummy and spread her legs. He squirted some lube onto Beth's finger.
'Work it up inside her,' he said.
Cautiously Beth put her finger against Pilar's anus. Her finger was so slippery that it went in with very little pressure. Beth had never done anything like this before; it was strange but exciting. Pilar wriggled a little and made some noises. Aidan told Beth to put more lube in. Then he gave her the plug.
'Put plenty of lube on it,' he said, 'then press it against her ass. Keep pressing gently and it will start to go in.'
Evidently Pilar was well trained in how to take a butt-plug, so Beth, despite her inexperience, managed to get it lodged in Pilar's ass without too much trouble. But it was clear Pilar found the whole thing acutely embarrassing. Doubtless that was the whole point as far as Aidan was concerned, to force her to submit to this young girl in a most intimate manner. Some doms, I know, get more pleasure from the humiliation of their submissive than from spanking or other kinds of pain. Forcing a girl to do something she's ashamed to do, especially forcing her to do it in front of others is a graphic demonstration of their power over her. And there is no doubt some submissives are extremely aroused by such things.
