The principal duty of the two slavegirls was to attend to their master's pleasure, especially during the long meetings and court sessions that took up much of his time. He preferred to hold them in the open air where the whole camp could watch and listen, but in unsettled weather he used one of the huts that still had an open front, having the tent part folded away. If it rained heavily, he retreated into his hut. Usually he sat with two or four chiefs or elders, and on ceremonial occasions wives joined them, all sitting on chairs that were big and elaborately carved, but made of light wood with the thick parts hollowed out, and easily moved around the camp.

When meetings were in progress, Beatrice and Ulaini, usually together, would sprawl or kneel at Abudu's feet, forming a little tableau that, given his size and girth, strongly resembled Princess Leia with Jabba the Hutt in Star Wars. The chief wore a leather outfit with a kind of skirt that resembled a kilt in both length and shape, and if it was pulled down to his knees, the two girls were expected to caress his calves and feet with their lips and, if available, their hands. Sometimes Ulaini's were bound behind her back, and occasionally Beatrice was made to step through her ankle chain, and everything was then shortened and linked together, putting her in a kneeling hogtie. That made her role both more limited and more challenging. Whether in extra restraints or not, she always had to move carefully. Her chains, ideally, needed to rustle suggestively, but not so loudly as to distract attention from the meeting. The other participants usually had slaves with them, though never more than one, and she had to take into account any noise that they were making.

At apparently random intervals, the chief would ease himself off his seat and pull up his skirt, opening it at the front to expose his genitals. There were two signals that he gave, and the girls had to be trained to recognise them. If he kept his legs together, one was supposed to remain at his feet while the other came up to address his penis, licking, sucking, and stroking it, slowly bringing it fully erect. If he opened his legs, the other slave was supposed to get underneath to take his balls into her mouth. The seat was the shape of a flattened horseshoe, supporting his buttocks but leaving a gap to allow them to hang down.

The slavegirl's task was demanding and required finesse, timing, and experience of their master's reactions. They were supposed to give him pleasure, but not to make him climax. It would create the wrong impression if he ejaculated while discussing a newly widowed woman's inheritance, or adjudicating a difficult divorce. There were more signals to watch out for. He'd push gently at a head that was working too hard, and stroking a cheek meant 'steady as you go'. A hand on the back of a head meant 'full speed ahead', in Swahili, of course. He preferred to cum when routine business was being discussed, and someone else was taking the lead. Another suitable time was just before an adjournment. Ideally, Beatrice would be the one to take the load, having been trained by the Wasir in deep throating, but Ulaini had good strong lips and was quite capable of bringing him off. Getting the timing right was their biggest challenge. Abudu was slow to arouse, but then quick on the trigger, seeming almost to suffer from premature ejaculation. Beatrice thought that dealing him was rather like scrambling eggs, when a few seconds separated a sloppy mush from a pile of rubbery lumps.

Luckily, Abudu was a genial and tolerant master, and he set the tone for the whole camp. No formal whippings ever took place, and miscreants were usually tossed over a lap and soundly spanked. The white overseers sometimes used switches as they trained the newly arrived coffles to display themselves for auction, and the handful of available chastity belts were sometimes used on pleasure slaves who were caught masturbating. The ultimate punishment was to be bound tightly to a post outdoors in heavy rain. Slaves were occasionally staked out flat, but always on higher ground once it was realised that the stream sometimes flooded. It was still not a terrible fate, and the tribesmen often liked to have slaves on display in the normal course of events. They had to be oiled to look hot and sweaty, for the English climate didn't have the same effect on the human body as that of sub-Saharan Africa.

Beatrice found herself outside in the rain just twice. Abudu cultivated- or rather neglected- a forest of facial hair, and was generally good-humoured when his wives and slaves found it scratchy and irritating. Ulaine seemed able to tolerate it, but when they lay together, Beatrice found that it tickled and got in the way of virtually any sexual activity. He was annoyed when she obviously tried to avoid his face, and the last straw was when she brought her knees together in an attempt to stop him giving her cunnilingus. That earned her a full afternoon in the rain. The second incident was when she'd been loaned to another chief's wife. She pulled away sharply when the woman, in the throes of a massive climax, suddenly began to slap her face, very hard. She didn't serve either sentence in full. The rainstorms weren't long enough, and the camera operators were able to take so many shots from different angles that it was possible to make the ordeals seem longer than they actually were. It was a huge hit with the viewers, and offered as separate clips as well as part of the episode. The cascades of water running down her body, pouring over her breasts and dripping from her nipples, made classic and memorable adult viewing. As the channel expanded, offering more and more alternatives, Max ensured that there was always, day and night, at least one slave in erotic predicament bondage. The water wheel was no longer presented as a punishment but as a training device, strengthening and firming the chest muscles by promoting deep, regular, and controlled breathing. As Abudu didn't believe in exercise, Beatrice and Ulaine never enjoyed that, and it was mostly the European employees who used it on their own slaves and the auction stock. If it every had any appeal to the (mostly) women who spent an hour or two bound to the turning wheel, it declined as the summer faded into autumn, and the temperature of the water in the millrace dropped.
