Saturday Morning
It had been a strange night for John, having a naked slave girl sleeping at the foot of his and Olivia's bed. For her part, Olivia had not pressured John to do anything he was not comfortable with, and while he had seen his wife out of the corner of his eye while he fucked Sarah bent over the end of their bed last night, she did not seem to expect him to do anything else once he had cum over the girl's back.
The experience itself had felt slightly wrong at first -- after all he was having sex with a woman who was not his wife for the first time in years -- but the fact Sarah seemed to very much be enjoying the position she was in gave him the motivation to live out at least this part of the fantasy.
It seemed odd to him to order Sarah to do anything once he was finished, so he simply pulled up his pants and left the naked cum covered girl where she was.
Olivia then announced that a good slave girl should get used to wearing her master's cum, and simply locked Sarah's collar to the end of their double bed, where she stayed, curled up like a dog, for the rest of the night.
A few times John had woken up and looked down at the end of the bed to see Sarah's pale naked form in the light from the window. He would then look over at Olivia in her modest pink pajamas, sleeping fitfully and seemingly completely unconcerned with the turn of events. Eventually though fatigue got the better of him and John drifted off to sleep.
As consciousness returned the following morning, John became aware to two things. One was the inviting smell of coffee now permeating the studio apartment; the other was a pair of soft wet lips wrapped around his cock. Still groggy from sleep, he looked up to see Sarah's pussy inches from his face, as she straddled his chest facing away from him, her head down between his legs, her mouth on his dick.
'I see the alarm clock is working.' Olivia said as she walked into the room carrying a tray with two steaming cups of coffee on it.
'Mmmm...' John replied, caught between a rapidly building orgasm and his brain's efforts to orientate itself. 'I think I'm going to cum...' he choked out after a moment, caught up in the strange situation he found himself in.
'Slave!' Olivia commanded, 'turn and face your master so he can look into your eyes when he comes in your mouth.'
Sarah twisted around on the bed, not once letting John's cock slip free from her mouth. When she was finally crouched between his legs, looking up with a mouthful of dick, she increased the speed at which she was sucking his member.
'A good slave takes all her master's load.' Olivia said stepping up to the edge of the bed and grabbing Sarah's hair, before driving the girl's head down onto John's cock as far as it would go.
'Ughh!' John thrust his hips forward and unloaded his cum into Sarah's mouth while Olivia held it in place. Sarah made only small choking noises, until the last spurt of ejaculate had been shot down her throat. Then Olivia let her head go, pushing Sarah to the end of the bed, where she curled up naked with cum dripping from her mouth. Olivia then sat down beside John on the bed, handed him a cup of coffee, and the pair drank and relaxed, as if it was most normal thing in the world that he had just mouth fucked another woman in front of his wife.
In many ways the next couple of hours were a pretty normal Saturday morning for John. He showered, dressed and had some breakfast. The only oddity -- apart from the way he had awoken and the events of last night -- was the naked woman cooking their food, cleaning up after them and, when not ordered to do anything in particular, who knelt in their living room, arms behind back, legs spread wide. Olivia seemed to be taking complete advantage of Sarah's body, and encouraged John to do the same. If they were sitting on the couch, Olivia would have Sarah knee beside her so she could fondle the slave's tits, or rub her pussy -- though taking care never to let Sarah orgasm.
At one point John found himself getting hard watching Sarah bent over, cleaning the kitchen table. Olivia noticed the erection in John's pants, and slid over to where he was sitting on the couch. Freeing his dick, she started coaxing it to full hardness, while pointed looking at Sarah's ass.
'It's what she's there for. You don't need to ask permission to use her holes if you're horny.'
With a confidence he hadn't felt last night, John got up and walked over to Sarah. Without a word, he pushed her down onto the table, so she was fully bent over, and thrust his cock into her cunt. John was surprised to find she was already quite wet, her pussy accepting his dick with little resistance. For a few minutes John fucked Sarah while Olivia watched, but then decided he wasn't ready to cum again yet, and so pulled out and went back to the couch. Sarah, who had not even looked up from her task, immediately went back to cleaning.
About mid-morning, after what was by any standard a fairly lazy Saturday, Olivia ordered Sarah to come and knee in front of them.
'I think, Master John, it's time we give our new slave some training.'
