He'd moved the big leather pouffe in the sitting room to the spot where she'd stood the previous evening and set up one of the cameras to the side pointing at it. Beneath the pouffe and extending for a couple of metres up to the camera was a another plastic sheet. He looked up, 'Ah! Just in time. How are you feeling now hon?' 'Pretty good considering, thanks,' she smiled. 'Whatcha up to?' He appeared to have misheard her question and patted the top of the pouffe. 'Kneel down and lie on here a moment, he commanded. She did so and he grunted before tapping her rear. 'Up a moment.' After trying various combinations he eventually added a dense foam block at the edge and arranged her such that her belly and hips rested on this and were raised with the rest of her upper body sprawled across the leather surface. He'd even provided a pillow for her head. She gazed at the now familiar image of her anus and sex on the screen. She made her mouth resemble the vertical lips and mouthed 'Hi' to them. 'Tail?' she enquired. 'All in good time. You are by no means ready yet. Here, look at this.' He held the smaller blue butt plug with a bulbous part almost the size of a small Satsuma in front of her face. 'Bloody Hell!' she exclaimed and the image of her anus shrunk to a tiny dot. 'You've gotta be kidding?' 'My darling,' he said calmly, 'By the end of this afternoon you will have had this and much more inside you and welcome it gladly.' Lucinda remained to be convinced and glanced to the much bigger black plug that was twice the size and was thankful at least that it wasn't that one. He added, 'It will prepare you for future training, particularly at the Stables where, I think I mentioned, they are not so gentle. Again the reference to these 'Stables'?

'Anyway, no more chatter. Look and learn,' he directed. 'Yes Master' she murmured and folded her arms under the pillow then snuggled down to watch. As during the previous evening's training, the visual detachment gave the whole thing a slightly unreal feel as though she was watching another person. Peter went into lecture mode again. 'The anus is a remarkably elastic ring of muscle. It can stretch to alarming diameters when properly conditioned but the delicate membranes of your rectum and the skin just inside can tear very easily. The aim is to gradually increase the opening without forcing and causing damage.' 'Now, since you were born your anus and bowels have been learnt to expel waste matter.' 'Hmm, I noticed that' she muttered, starting to get fed up, 'some I people I know even use their mouths,' she added, giggling. He smacked her raised rump, 'Shush, this is important.' Lucinda reached back and patted his hand. He moved it and ignored her. 'By repeatedly expelling objects, you quickly get to learn how to relax your muscles at will. If you don't manage this and tense up, I can assure you it is very painful. So, time for some games.' 'At last!' she thought and, resting on her forearms, wiggled her rear up at him like an excited puppy ready to play. She watched him drag the coffee table closer and noticed that next to all the dildo things was a bowl of fruit, presumably from the supermarket earlier. This bowl sat inside another bowl that he placed between her knees. He held a much bigger bottle of gel over the fruit and liberally covered the fruit. 'OK, no peeking. Guess the fruit!' She closed her eyes and felt something round insinuate itself at the entrance to her anus. 'Grape' she said. 'Just remember them, test later.' She nodded. One by one the process was repeated with more items of fruit until they slipped in with the minimum of resistance. Six grapes and six cherries she reckoned. 'OK, expel them and watch the screen,' he instructed. She bore down and was rewarded with the view of a shiny dark red sphere peek out of her anus. With slightly more effort the cherry shot out closely followed by a rain of red and green fruit. 'Tada!' she cried, 'Six of each?' Peter applauded. 'Very good. Now again.' She rested her head and closed her eyes again and the game continued and she gave up counting and identifying the items until she felt something much larger forced into her followed by another and another. This time she felt some internal discomfort and shifted her position on the block. 'I'm going to need the loo again soon love,' she said. 'In a moment, watch now.' Her anus spread and spread around a deep purple core and a Victoria plum finally plopped into the bowl. She expelled the next one with a practiced squeeze and then the last. Amazingly her anus stayed half open gaping at her like a hungry mouth and she watched it slowly close until Peter placed the tip of a lemon at its lips. 'Now, I know you have nothing to expel, but pretend and do so, just like the plums.' Lucinda bore down again and, with a slight twinge, the lemon slid in. 'Crikey!' she exclaimed. 'It won't get stuck in there will it?' 'No way,' he laughed, 'there are some 30 odd feet of plumbing above that all designed to send things downwards.' 'But I saw some Web pages at work. Emergency Room X-Rays or something.' Peter laughed. 'Oh those. They are people who are mad enough to stick objects with sharp edges or weird shapes up there. I have no such plans. Don't fear... and give me my lemon back!' Lucinda squeezed very hard and, again with a slight twinge, the lemon appeared. She was amazed. She wouldn't have even suspected that her buttocks could part that far let alone her anus. 'Again?' she requested. He chuckled and obliged and she dutifully returned it. They repeated this four more times and the twinges had vanished completely but the friction of the peel replaced these with a much more exciting sensation that seem to find its way to her clitoris. Peter stood. 'Time for a break if you need the bathroom' he said offering Lucinda his hand. 'Aw' she pouted, 'Just when it was getting interesting.' 'Well hurry up then Miss Cocky Sod and we'll get onto some serious stuff.'

Lucinda skipped off to the loo and found that her bowels had filled with a sort of brown mucous that she disposed of. When she washed herself in the bidet she fingered her anus and marvelled at how it now pouted like her vulva that she fingered with her other hand, she even managed to get two fingers up there. Without really thinking she let her fingers drift up to her clitoral hood and stroked herself until she heard Peter calling.

'What have you been doing?' he demanded, 'Playing with yourself?' She flushed appropriately. 'Hmmm, we'll be getting around to self-gratification later. Remember your body is now mine, frigging yourself off without permission is tantamount to theft.' 'Hardly,' she thought but got his drift. 'Yes Master' she said in a hopefully suitably humble voice.

She looked down at the coffee table. The fruit bowls had gone and the dildos were well slicked and lined up like some crack task force standing to attention and waiting for the 'off'. At the end was the dumpy blue butt plug. This time a thrill ran through her bowels and loins.

She willingly assumed the position and even managed to make her anus open a little. Peter insisted on blindfolding her so that she could concentrate on the experience. One after the other, Peter worked at her with the instruments and, in the heat of the lights and the pleasurable sensations warming her, she drifted off into her special space again with only the occasional twinge and feeling of extreme fullness distracting her. With one particularly difficult item that Lucinda presumed was the blue plug she felt herself opening wider and wider until she feared she'd tear as he had described and whimpered slightly but, slowly and surely, the object found its way in and her anus closed around the narrower neck. He repeated this two more times and the sharp twinges reduced to a slight lingering ache as the plug found its natural home with its collar pressing on the flesh around her anus. She now praised Peter for insisting she was empty before they started, the thick bulb of the plug seemed to reach up into her very core and she felt all sorts referred sensations in her abdomen from her bowels and even up to her chest and shoulders. When she shifted to relieve the more uncomfortable of these, the object seemed fixed as though he held it in place. Just when it was getting almost painful she was delighted to feel Peter's fingers stroking her clitoris. 'Oh yes my darling' she murmured blissfully and thrust her sex back which impaled her further and indirectly heightened the sensations in front. Lucinda smiled to herself when his fingering stopped and she heard the sound of a zip. A force on the butt plug lifted her a fraction and she felt his penis slide into her vagina and his fingering resumed. They gradually built up a rhythm with the plug controlling her and forcing her back and forth on the leather pouffe and onto him. She parted her legs even further and, pressing down with her arms, arched her back and rode his penis as his weight on the plug coaxed her along. At length he froze and she felt the plug press deeply into her as he jetted again and again. Mercifully, his fingering resumed and her own shuddering orgasm shook her until she clamped down hard on him and the plug and went over the brink again. Spent, they both sank down, panting. Peter lay on top of her and kissed her neck and ear and, after a few moments, removed the blindfold. All she could see on the screen was Peter's scrotum and much hairier anus. 'God love, that was wonderful.' She paused for breath; 'You were right, I did take it!' she turned and kissed him. He returned the kiss and nodded over at the coffee table. The blue plug still lay there, greased and obviously used but now discarded. She looked down at her buttocks and Peter sat back grinning. A circle of black sat in the centre of her buttocks. 'But that's incredible!' she cried. 'I can't believe it's possible. It's not really the big one?' He pushed the collar up slightly and she saw her anus, tightly stretched and light purple, encircling the wide neck of the black plug with its bulb pulling her rectum outwards. Peter smiled, 'Push it out and you'll see.' Lucinda leant forwards, arched her back again and bore down with all her strength and recent experience. 'It's stuck!' she squealed. He kissed her neck again and stroked around her anus. 'It's not hon, just relax and breathe gently.' He slipped his fingers under the rim and slowly, with many sharp twinges, her ring expanded and expanded stretching white until the obese thing appeared and lost its tenacious hold on bowels with a sucking slurp. 'Thank God!' she muttered, relieved that she wasn't going to join the A & E statistics and suffer the consequent embarrassment. He sat back on his haunches, plug and penis dripping sticky fluid onto the mat. Correspondingly on the screen Lucinda observed her twin orifices pulsating slightly as they gaped and relinquished their own fluids. Lucinda gazed incredulously at her dilated anus and could even make out the inner surface of her rectum in the camera lights. Gradually her newly discovered 'erogenous zone' closed its mouth and she took Peter's hand and kissed it. 'Thank you Master' she breathed, 'but promise me one thing?' 'Yes my sweet, what is it?' 'Please, please, please don't tell me we are eating fresh fruit salad for dinner!' She was rewarded with a stinging blow on her buttocks that sprayed gel all over them both.

They stood in the bath and washed each other using the hand-held shower. Peter douched Lucinda's vagina and anus until she stopped expelling semen and mucous and she returned the favour by filling her mouth with water from the nozzle, then bathing his penis.

Suitably cleansed, powdered and again wrapped in towelling robe and pareo, Lucinda cooked some tagliatelli with tomato and basil sauce. The fruit had been safely disposed of down the chute. They sat at the breakfast bar in Peter's minimalist kitchen and were just finishing the dish when Peter looked up the clock. 'It's nearly 9pm' he said, 'do you want to start on the pony stuff now?' Lucinda was ambivalent, 'Yes, I do, very much but I also want to be awake enough to enjoy it. What time do you have to leave tomorrow?' 'I'm in London this week, Monday morning start,' he beamed. 'Yippee!' she cried, 'Then I'd prefer tomorrow, bright and early if that's alright?' 'Sounds great to me. By the way, why don't you stay here this week? It will help us consolidate your training.' She grinned, 'Aw, love. You're so romantic... 'Consolidate my training' indeed!' 'You know what I mean.' 'Yes, that'd be great, but I need to get some stuff from my flat. I can't go to work as a pony!' 'Oh I don't know, maybe you'd win an animal feeds client?' His gaze wandered over her, perched on the stool, and took in her naked breasts and the small skirt of the hand towel, 'or even in your Sharon Stone beaver shot gear?' She raised her arms and, wiggling her breasts at him, made a show of crossing and re-crossing her legs. He was pensive for a moment then grinned. 'What?' she asked. 'Nothing. Just an idea. OK, we'll pop over to your flat tomorrow and get your stuff. But what do you want to do this evening?' She thought a moment and smiled. 'Well. We could finish that pistachio ice cream I saw in your freezer. Then pour ourselves another drink and snuggle up in bed and watch some old soppy movie?' She could see that he was not overly taken with the idea, so she went on, 'Of course, given the crap on TV lately, it's likely that we'd get bored pretty quickly and, I'd probably gulp my drink down and end up with ice cubes in my mouth.' Peter's interest was now aroused, 'And?' he asked with a grin. She raised her foot under his robe then placed it between his legs as she played with a rogue piece of tagliatelli and popped the end into her mouth. As she slowly sucked the rest in, she added, 'And... I could finish the blow job I started in the shower earlier?' She stroked his scrotum with her toes and swallowed the pasta noisily. 'But, if you have anything else in mind, I'm all ears?' He shifted and started to get up. She looked miffed. 'Oh. Where are you going?' 'To fetch the ice cream,' he replied.
