A lesson in Sexual Mathematics [M/F] [Slight BDSM] [DDlg] [Trigger warning]

G sat on the train back from the city, aimlessly surfing on his phone. He had been working all day, and was ready to wind down at the hotel. Normally, his day would be done and he would be alone. Not lately, though. More than a year ago, he started an amazing sexual relationship with a sales rep at his company, and she would be waiting for him in the room. His phone buzzed and the text interrupted his aimless surfing. “In the room waiting for you ;)” It was her. She finished her day, and was now back at the hotel. He was tired, but she always gave his body a jolt. “2 stops away” he responded, and went back to stupid memes. He may be in his 40s, but he is young at heart.

Lena snapped her thong in place, and made sure the bright red fabric framed her ass cheeks. Just like he liked it. She looked in the mirror. Her white skin looked bright and pink, she couldn’t wait to see his caramel body, feeling her all over. She slipped on the sheer chemise and gave her nipples a quick pinch. She loved how perky they got when he was close by. She poured 2 whiskeys, one for her, and a double for him. She wanted to make sure he was relaxed and comfortable, to leave all his stress at the door.

Her phone chirped, and she knew it was him. “walking over, be up in 5” She moved through their suite, and turned on the TV to his favorite channel. She turned off all overhead lights, and turned on 2 lamps. As she sat on the sofa, her phone chirped again, and it was one of his silly memes. “10Mins of Anal, or 45Min blowjob?” She smiled and texted back “Option #3” just as she sent it, the locked clicked and G walked into the room. She gave him a super sexy smile, and the world drained away from him. This was their bubble, pleasure, exploration, and each other. Nothing else mattered, and they both cherished this time together.

Lena held up his glass, and G walked over, shedding briefcase, jacket, and loosening his tie along the way. He leaned down to kiss her, and she felt the familiar energy run all over her body. Her legs parted slightly, and she could feel the warmth between. He broke the kiss, and sat next to her, kicking off his shoes in the process. He took his drink and she wrapped her arm around him. She could tell he was tired, and she was here to do what ever he wanted. Lena rubbed his shaved head, and gently massaged his neck. “How was your day, he asked?” She gave a hmmph, but said no more. His phone buzzed and it was her msg. He read it and smiled. God, how he adored this woman.

This wasn’t just a fuck buddy thing. Yes, the sex was amazing, but they connected on so many levels. They lived in different states, and had their own lives and responsibilities, but in the bubble they were fire. Each encounter was better and more passionate. There was an ongoing challenge on who could make the other cum harder, cum better, and cum more. Being muli-orgasmic, Lena had him in the quantity department. G used that against her, and he seemed to know all the proper sequences to get her off, over and over. “So what’s option three?” He said taking a big draw from his whiskey. He smiled and looked at the glass, she always got everything just right. She knitted her eyebrows quizzically, and he lifted his phone. Lena laughed and said “3 hours of all of the above, and then some” She moved toward him, and straddled him. Took his drink and set it on the table. He tossed his phone away, and grabbed to big handfuls of her ass cheeks. She kissed him deep. “45 min mouth hug, 2 hours deep in your pussy, and 10mins in your ass?” He looked at her with his mischievous smile. “What are we doing sex math now, Mr. Man?” she said. “How many times do you think you would cum?” G asked as he massaged her ass, and nuzzled her breasts. Lena loved how he fucked her, but what she really liked was how he turned on her brain. That made all the difference. Even when they were apart, he had her in a constant state of arousal. She was his sex toy, ready to be played with a the drop of a hat.

Lena sat up and took her top off, and exposed her enormous 42DDs with his favorite eraser nipples. His mouth found one, and sucked it deep. She loved when he did that. She pushed back and removed his tie, and unbuttoned his shirt. Kissing his neck and chest. Gobbling up all his Latin musk, and breathing in his hard days work. Such a man he was. He was her Daddy, and she was his Kitten. Lena looked him straight in the eyes, and in her most studious voice “If a woman wants to cum 10 times, and her man wants to cum 3 times, in what order should they fuck?” Quick as a wit, he replied “Well I was going to make you cum 30 times, but 10 should be no problem.” He took off his shirt, while she undid his belt. She could already feel his cock was hard from her grinding on his lap.

Lena loves G’s cock. It is perfect for her. 7 inches fully erect, and it almost always is, with her. A plump helmet on it. Not too thick, but not too thin either. Just right! She is excited to release it and take him in her mouth. As if on cue, his cock springs to life, as she releases her Sexy Beast from its lair. Hungrily, she takes it deep into her mouth. G lets out a moan of approval, and she licks and sucks him expertly. Before him, she hated doing this, but for some reason she can’t get enough of his dick. G puts his arms on the back of the couch and reaches for the whiskey. He takes another gulp as Lena gulps his cock, and uses her tongue to circle his head. Already, a hint of precum entices her taste buds. Kneeling in front of him, she takes off his pants all the way and begins to massage and squeeze his balls. She is everything but gentle, and he loves how rough she is with him. He can feel the twitch of her technique, so he moves to join her on the floor. Her greedy mouth won’t let go, until he breaks her concentration. He kisses her and lays on his back. She goes back to his cock and wiggles her luscious ass for him.

The red thong is a stark contrast with her pale Irish skin. Her cheeks soft and cool to his touch, he smacks her gently. He rubs her. Trades spanks and grabs with varying intensity until her ass is nice and warm. Red welts begin to show the outline of his hand. With a violent jerk, he rips her panties off of her, and pulls her closer to his mouth. She is well trained, and knows what he wants. She throws her leg over his head, and they 69. His forcefulness, has her close and his tongue takes her over the edge. She cums quietly with his cock still in her mouth. As he licks her, the waves wash over her, and she stops to moan and enjoy his mouth. She can feel another building and his hands now hold up her full tits. He pushes her back and towards him, so she is sitting on his face. He loves the full weight of her curvy body on him. Her pussy grips his beard and her clit mashes into his tongue. She grinds her mound down and explodes all over his face. She is screaming now and his cock is begging to be devoured. After a bit, her orgasm subsides, and the intensity is too much. She spins around and jumps between his legs. He is still in bliss from her riding his face into the ground that his orgasm catches him by surprise. She has her hand pushing down on his pubes, and extending his cock to its full mast. She deep throats it, while her tongue swirls and spins and the spit makes it all glide over his head. Her other hand pumps his balls as she sucks him deep. His cock twitches and jerks as he yells with passion. She gulps the thick cum as it hits the back of her throat, and she swallows every drop. He pulls her to his face, and she kisses him deep. Licks her sex off of his face and then kisses him some more. 2-1 Lena if you are keeping score.

They move to the bed as the floor starts to get hard, and he lays her on her back. He positions himself on top of her, and kisses her deeply. He wants to take his time and enjoy this sexy woman. His hands explore her roughly, because that’s how he is with her. She enjoys his strong hands, and how they grab, and caress her curves. He works his mouth down her face to her neck, where he nibbles and bites her. Small red welts mark his territory. Her breathing is deep and slow, and her bosom lifts and rises with each breath. He worships them. Sucking each nipple for what seems like hours. He kisses his way down her body and caresses and embraces her belly. Her hips each get a kiss, as his hands move to her thighs. She spreads her legs wide for him, ready to serve him his favorite dish. He kisses all her mound and breathes in her sex. His kisses turn to sucks with her labia in hes mouth. His tongue circles and teases her clit, and she is on the brink again. He sucks her clit hard as a small pea, and her orgasm splashes her. Warmth and energy pulse through her, and she moans with delight. He devours her pussy. Eating her like a starving wolf, with his first kill in a month. Her pleasure is so intense, she squirms and wiggles, but he has her in his grasp. His hands behind her legs, pull her to him, and she is his prisoner. He can taste more and more of her liquids, and her moans let him know she is close again. He applies pressure to her clit in the form of a flat tongue that mashes it down while his hand pull her up. She is in rapture. She cries out in pleasure and soaks his face and beard again. Not done, he moves his fingers expertly inside of her, before her orgasm can plateau, his fingers find her G spot. His spot, the only man to ever give her amazing vaginal orgasms. The pressure is intense and another wave hits her like a thunderbolt. She screams so loud her voice rattles. How does he do this, every time?!! 5-1 now, she is breaking away.

Its too much, she has to stop him. She pulls him to her mouth and kisses him. He lays on top of her and his cock is rock hard again. She spreads her legs wide and she wiggles to try and get him inside her. She needs to feel him. She needs her Daddy inside her. The angle causes his cock head to rest on her clit, she bucks, but can’t shake him and so he kneels between her legs. Her pussy is glistening wet, and bright pink. His dark brown cock looks enormous against it. He takes his hand and teases her clit. Slaps it hard with his cock, and she yelps. With his cock coated in her juices, he draws circles on her clit, and she cums again. This is getting out of control. Why does she challenge him? This orgasm is smaller but none the less, real. And before she knows it, he enters her in one hard thrust. He forcefully slams himself into her and she has another small orgasm as his cock pushes deep into her. Her walls gripping him in a tight embrace. No matter how much he fucks her, her pussy is always tight. He knows how to stroke her, and she is helpless. The orgasms come fast and soft now, one after the other. His pace evens out and he is purposeful now. She cums again and she is in heaven 8-1 Lena with no looking back.

She can’t take anymore, she needs to feel him cum. She wraps her legs tight around his ass, and pulls him closer. She has him where she wants him. Lena wraps her lover in a lustful embrace and kisses him hard. She whispers slutty things to him. “Fuck me, Daddy” “Make me your slut” This sends a charge into him, and she continues “Fuck me like your personal slut, use me!” Her whispers turn to screams as he pounds into her. She cums when she feels his balls slapping her ass. His pace is frenzied now. He is on a mission. Plowing into her, harder and faster. He looks into her eyes and she sees an animal. She is in pure bliss, he is building and building and she senses he’s close. All the orgasms he gives her are great, but the one she has when he cums inside of her, completes her. It defines her. It makes her what she is, she is his. Always has been, and always will be. He is at the point of no return. “Breed me, Daddy” She moans. She is breathless, as he slams himself into her. “FUCK ME DADDY!!!” “OH MY GODD!!!” He drives fully into her. His cock pulses and throbs. A second passes and he erupts deep into her womb. His balls pumping ropes of hot, sticky cum all over her aching walls. This sends her over the edge, and they ride the wave together. Her-10, Him-2. He wont’ go without a fight

He collapses on top of her. Waves of pleasure surround them. His cock draining completely. Her pussy milking the last drops he has. Totally spent, he rolls off of her, and lays on his back. She lays on her side. Her fingers dancing on his body. She needs to stay connected to him. He needs her touch. She pets him and caresses him for several minutes, so grateful. He needs her touch, he is addicted to her. How does this man fuck her so well? So much better than anyone else ever has?! She can’t get enough of him. She kisses him deep, and licks his lips. Then she moves to his nipples and she kisses his chest. She can see his cock is glistening wet with their passion. She has to taste it. He tastes like them together. Him salty, her sweet. His balls twitch and his cock stirs. Her tongue flicks his head and she feels a bit of resistance. He starts to stiffen in her mouth. Oh my god. He is such a stallion! Surprisingly, his cock swells harder and harder. This is incredible. Its already been two hours and he is still raring to go. She knows he likes her to suck him slow with lots of suction. She puts her mouth right over him and her plump lips create a perfect seal. She is a vacuum and she does as expected. Her hands squeeze his balls and she can hear him moan. He moves his hands to the back of her head, and he grabs fistfuls of hair. She loves when he is rough with her. She loves being his woman and he is her man. He pumps his now rock hard cock violently into her throat. She gags a bit, but fights through it. She is his cocksucker and she is elite. She opens her throat and pushes past her gag reflex. She takes him deep, and nuzzles her nose into his body, and she cums again. How does he do this to her? How does he own her body like she deserves to be??! 11-2 now, but its not over.

Lena pulls off quickly and she gulps for air. Spit and tears smear her face and she loves it. He takes his hand to pull her hair roughly off of him. In one swift, violent motion, he throws her on her stomach and he pins her under him. His arm wraps around her neck. She is scared and excited. His cock is rock hard again and she feels it on her ass. She needs to feel him inside of her. Deep in her bowls, she needs him. Her ass cheeks push back against him, inviting him in. Her asshole puckers and kisses at the tip of his cock. He dips his hips, and shoves himself into her soaking pussy. He coats his cock with the mixture of his cum and her wetness. She cums on his dick again, like the the slut that she is. He knows what he needs, and what she really wants. He lifts his hips and her pussy releases her grip. His cock is soaking and slick. Her ass knows what is coming and she relaxes to the inevitable. She wants this more than anything, now. She is his Kitten, to do what he pleases. He presses his cock on her asshole, and together they feel it softly pop, and give way. She moans and whimpers, as he fully enters her. Her ass wraps his cock in a death grip. Her cold ass cheeks hug his balls in a lovers embrace. She is so tight, and he is ravishing her. It hurts so good, she cums again, knowing he is close. He hugs her belly with one arm, and her neck and breast with the other. They are closer than ever before. He is closer than anyone has ever been, there is nothing between them, and they are one.

He squeezes her tight in his arms. Her ass squeezes his cock. He explodes in thrilling indulgence. They are growling together. Two ravenous animals. She cums again and she cries. Overwhelmed by his powers, he kisses her softly. He is her pleasure giver, and her protector. He is her Daddy, and she knows it. She is his greedy slut, and that’s all he wants her to be. Her 13- Him 3. Its no contest.
