When Lawrence confided in Robert about his recent dry spell, he was never expecting this to come from that conversation. Robert had told him he has a mistress, one Robert is certain his wife knows about but has yet to confront him about. She's young, pretty, bright, and has an interest in physics- or at least is attracted enough to Robert to pretend to care about his ramblings.

Lawrence was skeptical. He doesn't know many men who are eager to share their woman, but Robert has never been like most men. Maybe it's a kink for him to have another man fuck his mistress. Robert was open about what the two of you get up to, and it's safe to say that neither of you are very reserved in the bedroom.

After thinking about the offer for a day or two, Lawrence agreed. Robert already had a time and place in mind. Seven o'clock on Friday at his house for dinner. His wife would be away with the kids until Sunday, giving them the perfect opportunity to explore.

Friday came quickly and Lawrence found himself standing on Robert's door step with a bottle of wine in hand. Robert came to the door and greeted Lawrence with a smile, then lead him into the kitchen. Once there, he saw your behind bent over in front of the oven.

You take the chicken out of the oven and place it on top of the stove. Lawrence thought it was a bit odd to have a mistress cook in the wife's kitchen, but he supposed you and Robert were playing house for the weekend.

You turn around and saw both men standing at the kitchen table. Your face lit up when you saw Lawrence, but his stomach dropped when he saw you.

"Dr. Lawrence!" you say excitedly, coming over to both men. Lawrence stares down at you with his mouth slightly agape.

"You two know each other?" Robert asks.

"Oh, yes, he's one of my professors," you grin. "When you said you had a friend from work joining us, I was afraid it was gonna be one of those weird old guys."

Lawrence snaps out of his shock and looks over at Robert. "I didn't know your..." he feels it's inappropriate to call you a mistress to your face, "was a student."

"I didn't think it mattered," Robert counters.

"Please come sit, I made chicken," you say, drawing both men's attention.

Robert sits down at the head of the table with Lawrence to his right, leaving the seat to his left for you. The table is already set neatly and you bring over the tray with the chicken on it. The meat is steaming and the herbs are fragrant. There's mashed potatoes, a salad, and enough wine to leave the three of you drunk.

You make polite conversation over dinner, and Lawrence can't help but find it a bit humorous that you're making a date out of an arranged hookup. He is enjoying himself, though, so he can't complain too much.

The conversation revolves around work, and each time you speak, Lawrence is reminded that you're his student. His kind, polite, curious student who always brings him an apple and sits in the first row. You are a brilliant student and your work is always impressive. He never thought you would be the type to get mixed up in an extramarital affair with Dr. Oppenheimer, but Lawrence supposes he doesn't really know the true you.

Your food is delicious, the best Lawrence has had in a while. He thinks to himself that you would make a good wife, then chastises himself for thinking that way about a student.

"What's the matter, Lawrence?" Robert asks, breaking Lawrence's train of thought.

Lawrence looks between the two of you. "I'm sorry, I'm just a little nervous," he says. There's a blush rising to his cheeks and he feels shy under your attention.

"Don't be nervous, Doctor. We'll take good care of you," you smile reassuringly.

You reach over and grab his hand. Your fingers are delicate and your hand is small compared to his. His heart races and he suddenly has the urge for more wine.

"I suppose since we're on the topic, we should discuss how the rest of the night is going to go," Robert says.

"That's a good idea," Lawrence agrees.

"To get the awkward question out of the way," Robert starts, as if this won't all be awkward. "Do you fuck men?"

Luckily Lawrence's mouth was clear of food because it would have been lodged in his airway after hearing the question. Lawrence clears his throat and looks between you and Robert.

"I... haven't."

"Are you interested?"

"In you?" Robert nods. "I don't know... I haven't really thought of it."

"We'll start off slow, then."

Lawrence's head is spinning. His coworker just asked him if he wanted to have sex and now he has to continue on living his life as if that's normal. As if he's not intrigued.

"What kinds of things do you like, Doctor?" you ask.

"Um..." Lawrence says as his mind races to find an answer.

"Any particular turn-ons you have?" Robert asks.

When he still doesn't answer, you speak up. "Well, I can tell you what I like and you can tell me what you think about them."

"Yeah," Lawrence nods. "That sounds good."

You scoot closer to him and rest your chin on your hand, somehow making yourself look even cuter.

"I like older men who have experience. They know what they like and aren't afraid to take it. I like a strong hand to guide and to please me. And I want to be worshipped." Lawrence listens intently with wide eyes. "How do you feel about that?"

"I, um," he clears his throat, "I like it. All of that. Sounds good to me."

You smile widely and look over at Robert. "How about Dr. Lawrence and I take turns on you, dear?" he says. You agree excitedly.

"You don't have to call me that," Lawrence says, feeling unusually timid.

"Call you what?" you ask.

"Doctor."

You stand up from your chair and push Lawrence's plate back so you can perch yourself on the table in front of him. Your legs are crossed but your skirt still shows a fair amount of thigh. It's nothing Lawrence hasn't seen before, but now he's allowed to look. Your feet hang between his parted legs and he traces the seam of your stockings with his eyes.

"But I like calling you that," you say, batting your eyelashes. "But I could call you professor if you'd prefer."

Lawrence's eyes flick over to Roberts, searching for signs of discomfort or objection, but only found a smirk.

"This is... inappropriate," he says. "You're my student."

There is a slight pout to your bottom lip. "Doesn't that make it better? I've seen the way you look at me in class, Doctor. I bet you've thought about what would happen if I came to your office and asked for extra credit."

Lawrence shouldn't be surprised. Robert wouldn't spend time with a girl if she wasn't a firecracker. You just look so sweet and innocent, it's difficult to fathom these dirty words are coming out of your mouth.

You uncross your legs and part your thighs, giving him a peak of your delicate panties. "No one has to know, Doctor."

You're a seductress disguised as an angel. You're the snake tempting him to take a bite of the apple and let the delicious juice drip down his chin.

Lawrence slides his chair back to make space in front of the table, then drops to his knees in front of you. He's staring directly at your clothed cunt and he can practically smell your desire from there.

"What are you doing, Lawrence?" Robert asks.

Lawrence looks over at him and expects him to be angry, but he is smirking. "You're not going to fuck my woman on the dinner table. You'll take her to the bedroom like a gentleman."

It's a bit ironic that Robert wants Lawrence to be a gentleman and fuck his mistress in his wife's bed, but he's the guest here, he's in no position to argue.

Lawrence nods and rises to his feet. He holds out his hand to help you down from the table, which you eagerly accept. You lead him through the house and up the stairs to the bedroom, Robert following close behind.

You turn the lamp on and turn to the two men standing in the center of the room and sit at the foot of the bed. "Daddy?" you ask, voice sweet as honey.

"Yes, dear?"

"Would you take my shoes and stockings off please?"

Everything about this situation surprises Lawrence. You call Robert Daddy? He is eager to kneel at your feet and take off your shoes and stockings when you are perfectly capable of doing so yourself?

Once your pantyhose is balled up next to your shoes on the floor, Robert begins to kiss up your legs. You hum with contentment as he does so, but you don't look down at him, no. You're looking at Lawrence.

"Come here, Doctor," you say, beckoning him forward.

He crosses the room to stand next to you. You reach out to grasp his tie and you pull him down to your level. His breath hitches in his throat at the display of dominance, eyes glued to your lips.

"I like when Daddy's in charge, but I always get what I want. He spoils me rotten, but that's the way I like it. Daddy knows what happens when he denies me, doesn't he?" you ask.

Robert peaks up from underneath your skirt. "I've learned my lesson," he says before resuming his exploration of your thighs.

"Are you going to give me what I want?" you ask, turning your attention back to Lawrence.

He swallows thickly. "Yes."

You grin. "Wonderful. Now, take off your shirt."

You let him go and he stands up straight. Lawrence is surprised that you're so demanding, almost entitled, but he's working open the buttons on his shirt anyway.

He reveals his pale chest dusted with light hair. His pink nipples are peaked from the cool air in the room and he feels a flush rise to his chest under your gaze. As he opens his shirt further, you can see the happy trail that leads underneath the waistband of his pants, and your desire for him grows.

While you watch Lawrence, Robert pushes your panties to the side to touch your pussy. He gently strokes your clit with his finger and tongue, caresses your folds with slow licks, and dips his fingers just the slightest bit inside you. He's teasing you, but you're not worked up enough to complain about it yet.

"Now the pants," you order.

Lawrence slips off his shoes and undoes his belt, letting his pants fall to his ankles. You lick your lips at the sight of him standing in his briefs.

"Daddy," you say, pulling him away from your cunt by his hair.

"Yes, dear?"

"Take your clothes off too."

Robert does as he's told and undresses. You watch Lawrence trying not to watch Robert and it amuses you. Once both men are left in their underwear, you pull down your skirt and take off your blouse, leaving you in your own undergarments.

You stand up and step between the two men. You place a hand on both of their chests and urge them closer. Lawrence hesitantly puts his hands on your waist and Robert grabs your hips from behind. Both of them explore your body with your hands, and when they touch, Lawrence gasps.

"No need to be so shy, Doctor," you say while looking into his eyes. "Daddy doesn't bite."

Robert tucks his face into the crook of your neck and does just that; he sinks his teeth into the sensitive skin and you gasp. Your back arches and your chest presses against Lawrence's.

The man in front of you looks down at your breasts, almost entranced by them. You notice, of course.

"You can touch them if you want," you say.

Lawrence studies your face for any sign of hesitation, but all he sees is you batting your doe eyes at him. He slides his hands up your torso and cups your breasts in his large hands. You hear him let out a shaky breath and both you and Robert chuckle.

"He's so easy, Daddy," you giggle.

Robert wraps his arms around your waist and presses his chest against your back. "It's been a while for him, honey. Don't be mean."

Lawrence's cheeks are a delicious pink and it makes you want to tease him even more. You run your hand down his chest, stomach, over the fuzz under his navel, and over the bulge in his briefs. His body jolts at the contact, so you do it again.

"Fuck," he whispers.

"That's a naughty word, Doctor. I didn't think someone like you would do something like this."

Your hand slips underneath the waistband and you grasp his cock. You give it one firm stroke and when he lets out a groan, you grin.

"Haven't you tortured Dr. Lawrence enough for one night, dear?" Robert asks. He's phrasing it to sound like he's trying to benefit Lawrence, but you know he's getting impatient.

"I just want one more thing, Daddy," you say, looking over your shoulder at him.

"Anything for you," he smiles.

You have a devilish twinkle in your eye, one Robert knows well. "I want you and Dr. Lawrence to kiss."

Lawrence gawks, his eyes flicking up to Robert's to see if he's also shocked. To his surprise, Robert looks as if you've just asked him the weather.

“You’re a scientist, Ernie. Do it in the name of research,” Robert suggests. “Or in the name of getting your dick wet. Whatever works for you.”

"Okay," Lawrence says hesitantly.

Robert moves from behind you to stand next to Lawrence. He gently places his hand on the taller man's hip and leans close. You watch eagerly as Robert reaches up to press his lips to Lawrence's. Lawrence is stiff, but he's not rejecting the kiss. He's pliant for Robert, allowing him to take control.

The kiss doesn't last long and there's no tongue, but it was enough to satisfy you. When the two men part, they both look over at you. Robert's pupils are lust-blown and Lawrence looks like he could pass out.

"Was that what you wanted?" Robert asks.

"It was perfect, Daddy," you smile. "Now Dr. Lawrence has earned my pussy."

You scamper off to the bed and lay down on your stomach. Your feet hang over the edge of the bed a bit so there's enough room for Robert by the pillows.

Robert walks around the bed, taking off his underwear before climbing onto the mattress and sitting in front of you. His cock is hard and leaking, and you bite your lip in anticipation of what's to come.

"You tell him what to do, Daddy," you say while looking up at Robert through your lashes.

With Robert's legs positioned on either side of your head, you open your mouth and take the tip of his cock into your mouth. He lets out a groan when you suck gently.

"Why don't you come give our good girl what she wants," Robert says over your head to Lawrence.

Wordlessly, Lawrence steps forward and gently grasps the waistband of your panties. You move your legs to make it easier to take them off and Lawrence is met with the sight of your dripping cunt.

"Fuck," he whispers to himself.

Lawrence takes off his own underwear and begins to stroke his dick while looking at your ass. Robert watches him with a raised eyebrow, wondering when he'll get to it.

"Eat her out first. You can't fuck her dry," Robert says.

"She certainly isn't dry," Lawrence says as he kneels behind you and spreads your legs apart.

You squirm a bit when he leans in, his hot breath tickling your inner thighs. He starts by licking up your pussy, vaguely aware that Robert did this earlier. He can't tell if he's tasting your juices, Robert's spit, or a mixture of the two, but it's intoxicating.

He teases your clit with his tongue while you do the same to Robert's cock. You can't help the moan that escapes your mouth when Lawrence works his tongue into you. His hands grip your thighs as he buries his face deeper into you, making his glasses dig into your skin.

It's good, too good, but you know getting fucked by him will be better. You pull off of Robert and look up at him with a pout. "Make him stop, Daddy. I wanna cum on his dick, not his face."

The idea of you soaking his face makes Lawrence groan into your pussy and he is reluctant to stop. You're clearly impatient because before he has the change to remove his tongue, you're reaching back and pulling him away by his hair.

Lawrence whines at the tug on his roots. It's an accident, an entirely involuntary reaction and one you will file away for later.

"You heard her," Robert says, giving Lawrence the green light.

You work your way farther down Robert's cock as Lawrence kneels on the bed behind you, positioning himself properly. The tip of the cock hits the back of your throat and you gag. Robert looks down at you sympathetically and cups your jaw, stroking it soothingly.

"Take it all, gorgeous. Don't choke on it, I know you can do it."

Lawrence would be lying if he said Robert's dirty talk to you wasn't also affecting him. His cock drips as he nears your entrance and he is certain he won't last long. His tip bumps against your folds and you tense up at first, but then relax.

"Go ahead, Doctor," Robert says with a teasing lilt. "Fuck her."

Taking directions from Robert makes Lawrence's cock throb, but he pointedly ignores the implications of that in favor of relishing in the feeling of your tight cunt as he pushes into you.

He goes slow as to not hurt you, but your hole swallows him up greedily so he figures he doesn't have to worry about that. Once he's seated fully inside of you, he lets out the breath he was holding.

He braces himself on his hands and knees and begins to rock his hips. After so long with only his hand, your cunt feels like heaven. Even the friction of his lower stomach on your ass makes him dizzy.

At the head of the bed, your lips are pressed around the base of Robert's cock and you're focusing on trying not to choke. He's praising you like he always does, but it's hard to hear him over the blood rushing in your ears.

Your lipstick stains his cock, marking him in a way that makes Robert's possessive hindbrain go wild. He tries to be considerate when you suck him off like this, but it's so difficult to stop himself from bucking into your mouth and making you take him.

Pretty soon, you're getting fucked from both ends. Lawrence is pounding into your cunt, dick dragging along that sweet spot inside of you that fuels the flame inside of you. Robert instructed you to relax your throat so he could grab your hair and work you over his cock at his pace.

This is always your favorite part of the scene, when your bossy, bratty demeanor is replaced by a needy, submissive one. You're still getting what you want, but the punishing strokes of both men make it feel like they're the ones calling the shots.

Your whines and moans are muffled by Robert's cock, but both he and Lawrence are making noise freely.

"You feel so good," Robert praises. "My pretty little girl."

Lawrence doesn't do any talking, save for the occasional swear. There's mostly heavy breathing and small moans coming from behind you, and that just won't do.

"Spank her, Ernie. Makes her even tighter," Robert says.

"Can't get much tighter," he says, breathless. He brings his hand back and delivers a slap to your outer thigh. You choke on a cry and like Robert said you would, you got tighter. "Shit."

"Her cunt feel good?" Robert asks. He knows how hot it makes you when he talks about you like you're not there.

"So fucking good."

"You like sticking your dick in students, Doctor?" Lawrence moans low and long. He drapes himself over your back to rut into you with a newfound desperation. "You're never going to look at her the same."

Robert's right. The two of you have ruined Lawrence's life. He won't be able to teach or even think about physics without thinking of his student with the tightest pussy he's ever fucked.

"I'm gonna cum," Lawrence says. He's embarrassed that he was so quick, but he held it off for as long as he could.

"You better pull out," Robert says, still forcing you down on his cock. "You wouldn't want to knock her up, would you?"

Lawrence curses and quickly sits up to jerk himself off over top of you. Robert watches intently, ignoring you while Lawrence squirts his cum on your lower back. He groans and his head lolls back, the fatigue and relief hitting him once he's ridden through his orgasm.

Lawrence stands at the foot of the bed to catch his breath, watching the scene in front of him. "You're not finished," Robert says, his voice noticeably more airy now. "You're not done until she cums for you."

Resuming his earlier position, Lawrence eats you out with the intent of having you soak his face. He rubs your clit with his thumb, fucks you with his tongue, and moans into your cunt, all while you get face fucked at the head of the bed.

"Good fucking girl. You're gonna make me cum," Robert says to you. "Where do you want it? On your face?" You try to shake your head but Robert's hand on the back on your neck makes it difficult. "You want to swallow it, don't you?"

You moan loudly and nod the best you can. Robert smirks down at you and his body relaxes as he prepares to cum down your throat. You allow yourself to be used and focus on the pleasure of Lawrence's tongue inside you.

Like the last time he got you close, it didn't take much time at all. Before you know it, your cunt gushes all over his face and you cry out. Lawrence's mouth floods with your cum and he drinks it down eagerly.

With one particularly deep thrust, the first spurt of cum hits the back of your throat, making you gag. You're helpless to do anything but take it, though you don't swallow yet. You know Daddy likes to see it in your mouth.

Distracted by Robert's orgasm, you don't realize that Lawrence is still working your pussy until it becomes painfully sensitive. Robert pulls out of your mouth and lets go of your neck and your body jolts, trying to escape the stimulation.

"Stop," you whine, but its muddled by the puddle of cum on your tongue.

Lawrence immediately pulls away and you look at him from over your shoulder. He's sweaty: hair wet, chest glistening, and glasses foggy. He looks absolutely wrecked, but you don't get to admire him for long because Robert pulls your attention back to him.

"Hasn't anyone told you not to talk with your mouth full, little girl?" he asks, holding your jaw. "Open up, let me see."

You do as you're told and stick out your tongue so he can see the pearly liquid. He smiles, satisfied, but it morphs into something wicked.

"Why don't you go give Dr. Lawrence a kiss, dear? Thank him for making you cum."

Robert gives you a look that screams don't question me. You sit up, legs shaking, and turn to where Lawrence stands at the foot of the bed. You don't say a word, but you look up at him with wide, tantalizing eyes.

This time, Lawrence doesn't look to Robert before making his move. He ducks down and cups your jaw with his large hand before slotting his lips against yours. You escalate the kiss by pressing your tongue to the seam of his lips and when he allows you entrance, you let the cum flow from your mouth to his.

Lawrence whimpers, surely disliking the bitter taste, but swallows it quickly to get it out of his mouth. Despite that, he keeps kissing you for a second longer.

"Did you like it, Doctor?" you ask once you part.

Lawrence isn't certain if you're asking about the sex or the cum.

"Yes," he breathes.

You smile widely and look over your shoulder back at Robert, who is still sitting shamelessly nude and spread on the bed. The three of you sit in silence for a moment before Lawrence starts to redress.

No one offered him a place in the bed for the night and he certainly wasn't going to ask to stay. You crawl back up by Robert and cuddle into his side, laying your head on his wife's pillow. You both watch as Lawrence rebuttons his shirt and slips on his shoes without untying them.

Once dressed, Lawrence looks at the two of you and clears his throat, suddenly feeling awkward. "Thank you for having me," he says.

"Our pleasure," you giggle.

Robert reaches over to the night stand and takes a cigarette out of his case and lights it. He takes a long, slow drag of it before speaking.

"See you on Monday, Doctor."

Lawrence smiles sheepishly and walks out of the bedroom and down the stairs. Work certainly is going to be different from now on. Most notably, no one will be able to address him without him popping a boner in the middle of a lecture.
