Prologue
So that he wouldn't leave her for another woman, Carol has given herself as a sex toy to her boyfriend, Arthur, and her BFF, Becca. She has also, inadvertently, given an opportunity to Becca and Arthur to start a relationship, not clandestine, but one right in front of her.
I couldn't wait to get to Carol's townhouse knowing I'd get to see Becca again. She was supposed to go there directly after work to train Carol how to perform oral sex on women.
I had a mad crush on Becca and she seemed to be interested in me. Not wanting to hurt Carol, Becca and I tried to keep the spark between us as dim as possible.
Fortunately, or maybe, unfortunately, Carol asked us to 'pretend' to be a couple while training her to be our sex toy. She liked, as she put it, the balance of that as opposed to Becca and me being individuals and pulling her, Coral, in two directions, and so that Becca wouldn't be 'the odd man out', so to speak. Becca and I would still have to keep our feelings in check.
I took a deep breath when I saw Becca's car in the driveway. She was here before me, and I could feel my pulse race. It's possible that I'd get to have sex with her today.
Becca let me in and kissed my cheek. I wanted to grab her and kiss her lovely lips, but I restrained myself as Carol was in the room. Becca turned towards Carol and spoke those magical words: Hey Coral. Carol's eyes closed; Coral opened them wide, and she stripped naked without hesitation.
I asked Becca if Carol wasn't supposed to strip whenever Becca or I was in the room. Why wasn't she naked already?
Becca: That almost created a fiasco. Carol's next-door neighbor was here when I came in. Without thinking, Carol kicked off her shoes and was about to disrobe. I grabbed and hugged her and whispered, "Wait until after your company leaves." The thought got through to Coral and she throttled back to being Carol. After the neighbor left, I told Coral to amend her previous instruction and strip only when we say, 'Hey Coral." We'll have to be careful that Coral doesn't pop up unexpectedly when one of us happens to come into the room when strangers are present. We may have another problem. OK, Carol - tell him.
Carol: Well, I enjoy the peace of mind when I'm Coral, so I morph into her even when you two aren't around. I've been going back and forth between Carol and Coral so often that the line between Coral and me is beginning to blur. This is happening after only a week into my training. Becca and I are concerned that Coral and I will blend into one another completely in the not too distant future.
Arthur: What's the downside? I've wanted Carol to eat pussy ever since we started seeing one another.
Becca: Oh Arthur, think about it. We wouldn't want Carol to be a sex toy twenty-four seven. She teaches school; she has a social life; - - she has a private life. We can't have her hitting on women she interacts with within her daily life. She'd lose her job; she'd be shunned; she might even be arrested.
Arthur: Isn't there a way to stop that from happening.
Becca: Hopefully. I gave Carol - cum - Coral instructions that she cannot morph or disrobe or have sex with anyone but you and me or someone we tell her to have sex with. She can't be indiscriminate about sexual encounters. We'll have to wait and see what happens if the Carol/Coral line blurs even more. We need to be circumspect and think it through before we tell her to do something - especially in public or whenever there are strangers around.
When I let it sink in, I realized Becca was right. We had to be careful or we might have a big problem.
Becca began putting Coral through her sex toy positions. Coral was doing them with a bit more ease and panache. I hadn't thought much of the positions and postures before, but now I could see Coral's femininity and poise rising out of Carol's lack thereof.
Arthur: I think that's enough position training for now. Can you give Coral a bit more training in cunnilingus? I'm more interested in seeing her eat pussy.
Becca: Yes, I agree. Hey Coral. I'm using this voice recorder and reading from a script I wrote out for your threesome training. I expect you to listen to and repeat practically verbatim the instructions I've spoken into the recorder.
When you go to bed tonight, masturbate and edge close to - but don't you dare orgasm. Dredge out your cum with your fingers and suck them clean. Listen to the tape as often as you like to fully understand your sex toy duty especially when Arthur wants a threesome.
Masturbate several times, but do not - DO NOT - orgasm. I brought along a spy-eye video device that we'll put in your bedroom, so we'll know if you do orgasm. I'm going to repeat this - sex toys don't orgasm. They create orgasms in other women.
If you can repeat my instructions almost verbatim when Arthur and I come back tomorrow after work, you'll be permitted to masturbate immediately and orgasm, but If you make mistakes or forget your lines, you'll be punished. You'll be given a second chance and be expected to know your lines perfectly. If not, your punishment will continue through a third chance. I won't tell you now what that punishment will be, but it will affect your nipples.
As it is, you squeal too loudly when you're pulled by your nipples to your feet from an obeisance position. You need to get to your feet faster or toughen up your nipples or quietly - and I mean QUIETLY, accept the pain. From now on, you're not permitted to vocalize any pain - or humiliation you're subjected to. If you make any sound above a low moan, that pain or humiliation will be repeated until you're able to accept it stoically. I know this is harsh, and you didn't expect me to be cruel when you asked me to train you, but IF I'm not cruel enough to mold you into a perfect sex toy, this whole business is a farce, AND you'll be right back where you started.
Of course, when you repeat the instructions, change the pronouns to make them sound like YOU are telling how to perform a threesome. In most cases, change 'you' to 'I', 'she' to Becca or 'the other woman'.
Now I'm going to use the voice recorder to tell you what to do. Open your mind and take the instructions to heart.
First off, when Arthur has a threesome with you and another female, he expects you to eat her out. You know that. Unfortunately, she may not be as - um - hygienic as you'd prefer her to be. She may not have showered or wiped herself clean after she pees or possibly be on her period.
However, as a sex toy, it's not your concern or yours to take that into consideration before you eat her out. You mustn't give that any thought. Just do as you're told.
Keep in mind, at all times, that you - Coral - are a sex toy - and - I'm going to repeat this over and over - sex toys do NOT concern themselves - with her owners' or owners' guest's physical condition, status, gender, cleanliness, appearance, or whatever. Like a puppy, you must love and obey your owners without regard to your own needs, desires, or comfort.
Becca stopping the recording: Coral, I haven't showered since yesterday morning, and for the rest of your training, I won't wash my genitals at all. It'll be up to you to keep my pussy licked clean. In order to service any woman that Arthur brings for a threesome, you'll have to get used to all situations such as a woman's unwashed, sweaty genitals from working all day, two days, coming straight from the gym, or whatever. So let's get started.
She starts recording again --
Arthur wants to watch you eat me out. You've had enough training to know how to approach another woman depending on the position she takes - on her back - on all fours - standing - or if she wants to sit on your face. Move to her crotch and take her pussy in your mouth with eagerness instead of a grudgingly, 'let's get this over with' attitude.
Let her know that you're hungry to eat her pussy, taste, and ingest her juices. Take your time licking her to orgasm but don't drag it out when she's eager to come - in your mouth, of course. After she comes, show her cum to Arthur and wait for permission to swallow. Make a display of ingesting her fluids and licking her clean. Think about what you would want someone to do for you if she were YOUR sex toy.
Make sure her pleasure comes first; don't concern yourself with your own feelings. If she happens to - er - have an unpleasant taste or - or - aroma, don't allow yourself to register that fact. In your mind you need to believe that her pussy is sweet and clean; otherwise, you might offend her by showing any disgust or disdain. If you're repulsed by her genitals or fluids, for heaven's sake, don't allow your face or actions to display it. You must strive to be the best-damned cunt licker you can possibly be under any and all possible situations.
Above all, DO NOT hesitate to perform any sexual act or action she or Arthur asks you to do. DO NOT show any revulsion you may feel. In fact, as a sex toy, you are not permitted to feel any negativity whatsoever. We'll go over that aspect again and again until you have only positive feelings about eating pussy and ingesting pussy juices.
