Diana and Ibrahim, then Diana, then Diana and Dave, then Diana, then Diana and…

Your colleagues push you to your knees on the floor and Diana hops up onto your desk, unceremoniously stuffing your head under her skirt—a skirt that you think may be forming part of her outfit specifically so she can do this. Her musky scent fills your nostrils and you're relieved to know that you're not the only one in a state of intense arousal. Her sex is bare and swollen, lips slightly parted, and there's enough light under the skirt to see the marks of knicker elastic. She's obviously removed her underwear in the last few minutes, presumably just before approaching you.

You eagerly apply your tongue to her slick folds, the sound of a zip from behind you warning that one of the men is about to join in. A pleasantly meaty prick slides effortlessly inside you, prepared as you are by the fingering you've received. You recognize it as Ibrahim's, even though you don't consciously remember having sex with him before. He grabs your hips and starts to pound you hard enough that you need both hands on the floor to steady you, although you'd love to add some fingers to your tongue in pursuit of your female subordinate's pleasure.

"Is it alright if I sit in your seat while you're on the floor, Ms, Cho?"

Rather preoccupied, you manage a thumbs up, together with an affirmative grunt, in answer to Dave's surreally deferent request and he immediately wheels the chair into position so he can reach down to continue groping your breasts. You're more concerned with Ibrahim, however. Like everyone you've encountered so far, he appears highly skilled in giving you pleasure, angling his penis to hit the inner walls of your vagina in just the right way. It occurs to you that this is not merely superior knowledge of female anatomy, but superior knowledge of your anatomy specifically. Clearly he knows from experience exactly how to get you off, which would be great in most circumstances, but is positively dangerous now.

You're **** to break off your oral ministrations to remind him that you're trying to avoid an orgasm and find yourself promising to service him as often as he likes, provided he doesn't make you cum. He shifts position, but the rhythmic thrusting is still threatening to overwhelm your defences. You go back to licking with greater urgency, hoping that if you can satisfy Diana quickly, you can get a break by sucking Ibrahim's dick. Unfortunately, the plan hits a snag when she climaxes powerfully as you suck her clit, but shows no inclination to release your head, continuing to grind your face against her crotch until you're short of breath.

You're digging your fingernails into your palms to keep your own orgasm at bay when Ibrahim starts to speed up, grunting with rising lust. You buck back against him, using all the skills you didn't possess until you meddled with the Rulebook to send him swiftly and satisfyingly over the edge. Eating a woman out whilst trying to drain a man's cock and hold back an orgasm is too much multitasking and you can sense Diana becoming frustrated by your lacklustre performance when the man hammering you from behind tenses up and spends himself deep inside you.

You return your attention to the woman in front of you, while Ibrahim mercifully slows down, sliding in and out a few more times until he's completely empty, then taking a moment to enjoy your warmth before pulling out entirely and trying to get up off his stiff knees. Dave helps him up and he straightens his clothing.

"Thanks, Jenna. See you tomorrow."

Your reply is muffled by Diana's second orgasm of the night, her juices running down your chin, whilst he saunters out towards the lifts as though shagging his team leader on his way home happened every day—which it might well do from now on. The respite is welcome but Dave's turn is next and if he's as skilled as his predecessor, you're far from out of the woods yet.

"Excuse me, Ms. Cho," he interrupts your thoughts. "If you don't want to, er, climax, would you like me to pinch your nipples while we…I mean while you give me an orgasm? Or maybe it would be easier if I put it in your bottom?"

You gargle unintelligibly, focused on licking, thrusting your tongue deep into Diana's sex, but he seems to take your reply as an affirmative to his second suggestion, because he starts to use your juices (and Ibrahim's semen) to lubricate your back passage. His fingers, first one, then two, find gaining entry far harder than the penis in your vagina, but the feeling is more uncomfortable than painful and you bear down to help him when he tries to ease his manhood inside.

The lack of energetic thrusting lets you take one hand off the floor to slide a couple of fingers of your own into Diana's gushing pudenda, freeing your tongue to lick her clitoris with rapid side to side movements which reward you with another climax. Whether stimulated by Dave's penetration of your anus or not, you'll never know, but she pushes your head lower, positioning your mouth over the entrance to her bum hole. You don't hold back, running your tongue over the puckered rosebud, finding it surprisingly fragrant.

As Dave starts to rock back and forward, groaning at the intense sensations, you hear an unexpected voice from so close it makes you jump.

"Hi, all. How many times has she cum so far?" The voice's owner sinks into your chair with a sigh of pleasure, without bothering to ask your blessing. You rack your brains trying to recognize him.

"She can't, uh, cum yet," Diana explains breathlessly. "She's not finished catching up on her work."

"Then why is she…?" The voice trails off.

"She just offered," Dave replies, now fucking you in earnest. It's not something you'd choose necessarily, but it's not as unpleasant as you might expect.

"I suppose I'd better wait 'til she finishes then and make her cum after. I bet she'll need it, after going without all day."

You still don't know who he is, but you're starting to like him.

"No need to wait that long. It might be a late night. Just tease her a bit while she's working and I bet she'll offer you the same as us just so you don't make her orgasm," Diana suggests. You glare at her pudenda, but continue to tenderly and lovingly lick her bottom, while yours continues to be stretched.

"But I want to get her off too."

"She's not interested in you, Brady." You can almost hear Diana rolling her eyes.

"I don't want to date her. I just want to give her some relief after all the teasing she gets."

You're pretty sure nobody in the room believes that and the name Brady still means nothing to you. Diana guides you back to her clitoris, apparently ready for round four and soon her cries of pleasure mingle with Dave's roar of release. He needs a few moments to recover before thanking you and rushing off to the bathroom to get cleaned up, but Diana's still not satisfied and doesn't release you until she's ridden your face to a fifth orgasm. Almost drowning in her juices, you finally get out from under her skirt and get your first look at the mysterious Brady.

"Hi, Jenna," he greets you, getting up from your seat and putting away the smartphone he was using to play a game.

"Hi, Brady," you return, glancing at his ID tag, which identifies him as Brady Allgood, from IT. You still don't recognize him and the Rulebook apparently feels that you don't need to know any more than you've already deduced. He's about thirty, average height, brown hair, okay looking, but not in great shape. He openly inspects your body while he helps you to your feet and gives your left boob a little squeeze. You rub your aching knees and sit in your chair, which is unpleasantly warm from his bottom. Yours is a little sore, but not too bad, considering.

You take a long drink of water from the cup next to Diana, who's still sitting on your desk, hair plastered to her face, blouse almost transparent from perspiration (she's wearing a nice lace brassière, you notice), but making no move to leave like Ibrahim and Dave. Maybe she's too exhausted by your ministrations, you think, with a trace of pride. Brady grabs another seat and you try to get back to work, but it turns out Diana has other ideas.

The attractive woman hops off the desk and squats beside you like she did earlier and again slips her hand between your thighs. You look pleadingly at her, but she mercilessly edges you, forcing you closer to disaster with each passing moment.

"Please," you beg, squirming helplessly, "I'll give you orgasms whenever you like. I can't take much more."

"What about Brady?"

"What? Yes, okay, him too, whenever he wants, please Diana!"

"And you don't want him to make you cum, either?"

"No, I just want to give, please, pleeeease!"

You reach the point of no return and fear that she's not going to stop, but at the very last moment, later than you thought possible, she relents and you almost sob with relief (and frustration).

"You hear that, Brady? She just wants to give, so you don't need to wait, you can have her right now."
