Dominated by His Seductive Sister-in-Law - Part 3

The sound of footsteps coming down the hallway lured Dean's attention from his computer. He looked up just in time to see his sister-in-law walk by the office door. She was moving fast enough that he only caught a glimpse of her, but Dean was certain Scarlett was fully naked.

The image of her lean, nude body lingered in his mind as Dean stared at the empty coffee cup on his desk. Earlier that morning Scarlett had instructed him to cum in his coffee before adding her piss, creating a potent combination of unpleasant flavors that he'd dutifully downed over the first part of his work day. He could still taste the saltiness on his tongue, though there was a part of him that found that taste thrilling, as it triggered his submissive desires.

"Dean!" Scarlett called out.

He pushed his chair back and practically ran out of the office and towards her voice. Dean found his way to the living room and saw his sister-in-law sitting naked on the couch with her legs crossed.

She looked up at him with a smile on her face and said, "I'm surprised you didn't come running the moment you saw me walk by the door."

"I wasn't sure if you wanted me to follow," he replied. "I didn't want to presume." His gaze wandered to her breasts, which looked stupendously perky. Her nipples were hard, too, and Dean wondered if that meant Scarlett had something naughty in mind.

"I suppose that's a good thing," she said. "I do like that you came the moment I called for you, though. I like that you're so obedient, Dean." She spread her legs just a little and Dean felt his heart begin to pound. "Do you like being obedient, Dean?"

"Yes, I do," he answered with a nod while staring between her creamy thighs.

"Does it excite you to see me naked on your couch?" Scarlett asked.

He nodded again as that excitement coursed through his body.

"And do you feel a desire to worship me, Dean?" Scarlett asked. "Do you yearn to be given permission to worship my body?"

"Yes, more than anything," Dean answered as his cock grew in his pants.

"Get on your knees," Scarlett instructed softly.

Dean fell to his knees and looked up at his sister-in-law. Her lips curled into a slight smile and she ran her fingers up her stomach before taking hold of one of her breasts and squeezing the flesh softly. She took her nipple between two of her fingers and pulled on it before rolling it slowly. A moan escaped her lips as Dean felt his cock throb in his pants at the mere sight of the beautiful naked woman indulging in just a hint of self-pleasure.

"Crawl to me," Scarlett said.

Dean obeyed without hesitation, crawling towards Scarlett and stopping in front of her. He let his gaze linger between her legs, admiring her swollen labia and her clit, which had emerged from under its protective hood, in a seeming declaration of her desire. Dean couldn't help but feel elated at the notion that Scarlett wanted to control him - to play with him - so soon after their morning interlude.

"What is it you crave right now, Dean? What is it you want more than anything?" Scarlett asked as her fingers moved to her other breast to continue manipulating her tender flesh.

"I want to worship your body," Dean answered. "I want to kiss and lick you all over. I want to put my tongue into your pussy and taste you. I want to lick and suck on your clit until your body is tingling with pleasure and you can't help but have the kind of orgasm that makes you scream."

Scarlett unleashed a full, beautiful smile. "Such a vivid imagination," she said. "Are those the things you wish my sister would let you do, Dean? Do you wish she'd make fuller use of your...tendencies, of your desire to do whatever it takes to please her?"

"Yes," Dean admitted.

Scarlett spread her legs a little wider and gently rubbed her fingers over her pussy. She seemed more intent on teasing him than pursuing her pleasure, for her clit received only a hint of stimulation. "And do you feel guilty about being on your knees in front of me, Dean?" Scarlett asked. "Do you feel guilty about begging for the chance to pleasure your sister-in-law?"

"I do," Dean said. "And yet...I can't help myself, Scarlett."

She plunged a finger into her pussy and Dean watched it disappear without resistance. As it moved in and out of Scarlett's pussy, he could hear her extreme wetness, indicating that she was just as excited as him.

"I know," Scarlett replied. "I like that you can't help yourself, Dean. I like that you want this so badly that you're willing to take the risk. In fact, I love it." She added a second finger to her pussy and it slipped inside her with ease just like the first had. "Now tell me, did you finish your coffee, Dean? Is your belly full of cum and piss?"

Dean felt a shudder of pleasure move through his body as he considered exactly what he'd done for Scarlett's pleasure. He'd consumed her piss. He'd consumed his cum. The notion still aroused him, long after he'd done it. "Yes, I did. I drank every drop."

Scarlett closed her eyes and moaned as she gently rubbed her clit. "Mmm, Dean, I can't say that I understand why, but I love that you drank my piss. I love that you drank your cum. I love that you did it for me."

"I did," Dean said. "I did it for you, Scarlett. I did it to make you happy."

Scarlett smiled and lifted one of her lovely feet. Her toes came to rest just a few inches from his face and she instructed, "Suck on my toe. The big one. Take it in your mouth, and look at me as you do it."

Dean leaned forward and took the toe into his mouth as instructed. He sucked on it. He swirled his tongue around it. He stared into Scarlett's eyes and he watched as a mixture of joy and pleasure washed over her face.

"Mmm, such an obedient boy," she said.

Dean moaned as he felt a deep sense of arousal rush through his body. He moaned at the intense pleasure of doing exactly as Scarlett desired, and at her seeming eagerness to explore his willingness to submit.

Scarlett pulled her foot from his mouth and set it on the floor. She plunged three fingers into her pussy and fucked herself as she said, "Bend over. Kiss my feet. Both of them. Slowly kiss your way up my legs. Take your time, though. Worship my body as you say you desire."

Dean dropped down and showered Scarlett's beautiful feet in kisses. He closed his eyes and planted his lips against her flesh over and over. She masturbated throughout, gently fingering her pussy and rubbing her clit, adding in a chorus of soft moans that danced through Dean's head and triggered a steady stream of arousal that coursed down his spine and between his legs, leaving him hard enough that his cock ached in his pants.

Dean kissed his way up her legs, showering her soft, smooth skin with affection. As he reached her knees, Dean gazed between his sister-in-law's legs and saw her enflamed pussy lips and the wetness between them.

"Does my pussy look good, Dean?" she asked. "Does it make your mouth water to see how slippery my tight little cunt is?"

"Yes," he answered. "Fuck, Scarlett, yes, your pussy looks so beautiful."

Scarlett slid her hips forward, inching her pussy closer to Dean's eager mouth in the process. He kissed her thighs, pressing his lips against the warm, impossibly soft flesh and eliciting gentle moans from his sister-in-law in the process.

"Do you want to worship my pussy, Dean?" Scarlett asked.

"Yes, desperately," he answered.

Scarlett pulled her fingers from her slippery pussy and sucked them clean as Dean stared at the pink flesh she'd just vacated. Scarlett was utterly soaked and all he wanted in that moment was to plunge his tongue inside her to taste his sister-in-law's sweet juices.

Dean figured he'd be given permission to do so, but Scarlett had another idea. She lifted her feet from the ground and pulled her legs back, exposing her tight, smooth, wrinkled asshole in the process.

"I know you want my pussy, but I don't want you to have it yet," Scarlett said as she held her legs back. "Instead, I want you to show me how desperate you are by worshiping my asshole. Now kiss all around it."

Dean leaned forward without hesitation and kissed the area around Scarlett's perfect asshole. He held eye contact with his sister-in-law as he did it, showering her with a very particular kind of affection that put a bright smile on her face.

"Now kiss it, Dean," she said. "Kiss my asshole."

Dean smiled and pressed his lips against her asshole. He let them linger there for a few moments and the sound of an audible kiss filled the living room.

"Again," Scarlett instructed. "Show me what an obedient boy you are and kiss my asshole again."

Dean kissed it over and over. He kissed it because he wanted to be obedient, because the pleasure of that obedience coursed through his body and left his cock throbbing with delight. He kissed it because it clearly turned Scarlett on to watch him do so, and all he really wanted in that moment was to arouse her.

"Now lick it, Dean," she said with an edge to her voice. "Lick my asshole."

It felt like such a dirty command, and yet that only propelled Dean's desire. His tongue slipped out of his mouth and danced over her asshole. He licked as commanded and Scarlett rewarded him with a moan. Her pleasure compelled him to a deeper level of passion as he pressed his face between her ass cheeks and made love to her anus with his tongue.

"Fuck, I can't believe how good that feels," Scarlett said before closing her eyes and moaning while rubbing her clit. "My sister is missing out. She should have you worshiping her asshole every fucking day. She should put you on your knees to eat her ass. She should sit on your face and smother you with her ass while she plays with her cunt."

Dean moaned.

"Would you like that?" Scarlett asked as she looked down at him. "Would you like it if Anna sat on your face and made you eat her tight hole while she played with her pussy?"

"Yes," he said before his tongue immediately returned to worshiping her asshole.

Scarlett moaned loudly, but then she pulled back, depriving Dean of her asshole. He thought he'd done something wrong, but a bright smile remained on her face. "Turn around and lean against the couch," she instructed. Dean did so and Scarlett stood up and moved until she was standing astride his body. "Lean your head back. Rest it against the couch cushion."

Dean leaned his head back as instructed and looked up to see Scarlett's beautiful ass. She slowly lowered it until her round, smooth cheeks rested just a few inches above his face.

"Do you want me to smother you with my ass, Dean?" she asked.

"Yes, please," he begged as arousal hummed through his body, leaving his dick in a painfully erect state.

Scarlett's ass continued its slow descent. Her cheeks parted and her asshole settled over his mouth. She lowered more of her weight onto his face, smothering Dean as he licked her asshole. His head pressed deeper into the couch cushion as Scarlett found a comfortable spot and resumed playing with her pussy. The sounds of wetness filled the air along with her moans, indicating her joy at sitting atop her brother-in-law's face while he ate her ass.

"Put your tongue in my ass, Dean," Scarlett instructed.

Dean stiffened his tongue and pressed it against her asshole. He felt Scarlett open up for him as she moaned. His tongue slipped inside her rectum and she dropped more of her weight onto his face. It got harder to breathe beneath her, but Dean's dick was harder. He was offering his complete submission by acting as little more than furniture for his sister-in-law and the fact that his tongue was in her asshole only made it more exciting.

"Mmm, I had no idea how good this could feel," Scarlett said as she played with her pussy. "In fact, it feels so fucking good that I'm not going to let you taste my pussy. I want the taste of my ass to remain in your mouth as you go back to work, Dean. I want it to stay on your tongue as you try your best to concentrate. Fuck...you dirty little ass eater."

Dean wanted to masturbate. He wanted to stroke his cock and enjoy a thrilling orgasm. He kept his hands at his sides, though. He worshiped his sister-in-law's asshole eagerly. He remained every bit as obedient as she wanted him to be.

"Fuck, Dean, I'm cumming!" Scarlett cried out. "I'm cumming!"

She dropped most of her weight onto his face, truly smothering Dean and making it impossible for him to breathe as her ass cheeks quivered from the pleasure of her climax.

Only when she was finished did Scarlett lift her ass from Dean's face. He sucked in a deep breath of air as she turned around and smiled down at him. He looked up at her flawless naked body and she said, "What if I wanted to piss in your mouth right now?"

"I'd let you," he said as the idea brought with it a surprising rush of pleasure.

Scarlett smiled. "I thought you'd say that. Maybe I'll take that pleasure before my vacation is over. Maybe I'll give you that reward if you earn it."

Much to Dean's surprise, the notion of Scarlett pissing in his mouth felt like a reward in that moment. "Thank you," he said. "For sitting on my face. For letting me worship your ass. For cumming while my tongue was in your ass. For giving me the pleasure of making you feel good."

"It turns out you're quite good at making me feel good, Dean. Make sure you give my sister some of that attention when she gets home from work. I'd suggest a foot massage, then see how she feels about having her feet kissed and her toes sucked on," Scarlett suggested. "See how she feels about you kissing your way up her legs. Don't eat her ass, though. I think we both know she's not ready for that. You can eat her pussy, though. Oh, and I'm sure she'd be much more likely to be in the mood for such pleasures if you prepared dinner for all of us."

"I will," Dean said.

Scarlett smiled and added. "Now back to work. Oh, and if you make yourself another cup of coffee, let me know. I'd like to flavor it with my piss once more, as I think we both know it will turn you on to taste me in your coffee, won't it?"

"Yes," Dean admitted.

She turned and walked away without saying another word. Dean rested his head against the couch once more and smiled. He could taste her ass on his tongue. He could taste the dirtiness of what he'd just done and he loved it. He'd go back to work and at some point he'd make another cup of coffee, because as gross as it was, he couldn't resist the idea of getting to drink his sister-in-law's piss for the rest of the day. Something about it was just so naughty, and so thrilling as a result.

He'd do what Scarlett suggested and make dinner, too. He'd do everything he could to try and convince Anna to let him between her legs, for worshiping his wife and his sister-in-law in the same day sounded exceptionally hot.
