Forbidden lust-in-law (Mf)

James’ felt the nylon of Kim’s Nike shorts tug against his knuckles as he slid his hands the last millimeter up the back of her thighs and onto both of the soft cheeks of her ass.

Kim tensed up and turned to face him as James reassured her, “Relax, it’s okay”. Her dark brown eyes wavered between him and the door for a second, then she lowered them and put her head back down against the blanket. She inhaled deeply then released the last bit of hesitation from her body.

James continued up her shorts until his hands were no longer visible in the dark room. He pushed up towards her back with his palms and pulled the lower part of her cheeks apart with his thumbs, allowing him to feel the warmness radiate from between her legs.

The tips of his fingers brushed against the waistband of her panties, as he rubbed. Her skin was cooler than he’d imagine, but each second his hands grabbed her ass she warmed up. With his right hand he grabbed a bunch of the cloth of her panties and tugged. With his left palm he traced down her crack until he hit the crotch of her shorts.

James’ heart pounded from the joy and relief of finally touching Kim’s beautiful body.

She had just turned 19 a week prior, but if James were to say he had only started getting aroused by her for the last year, he’d be lying. You see, Kim’s sister Sara of three years was James’ wife, and he vividly remembered when he became infatuated with her.

During the first year of their marriage, James and Sara lived with her family. Kim had been a sophomore in high school at the time, so she was quite unaware of her body and the fact that a male non-blood relative was now in her house. James often saw her small nipples poke through the various sports bras she flaunted around the house. He also walked in on her on the toilet once because she didn’t close the door the whole way. What he saw was a full glimpse of her naked leg and the side of her ass. It embarrassed them both at the time and was the turning point for when she started being more careful. But not careful enough.

Back in the dark room on his knees behind Kim on the blanket lying on the ground his cock got hard as he pulled her shorts down her leg and saw the outline of her vagina under her white panties.

He paused for a second and Kim looked at him and spoke in a hushed voice “What is it, someone coming?” She asked. “Why are you grinning?”

“I was just thinking of that time two years ago I saw up your skirt when you were acting goofy with your cousin” he replied.

“Oh my god that was so embarrassing” she exclaimed and promptly put her head back into the blanket.

He removed the shorts completely and rubbed back up her leg, brushing her inner thigh slightly as he moved his hands up to her sides.

Seeing up her skirt back then gave James a goal, he had to get her naked.

As she grew into a beautiful 18 year old, James started attending every one of her soccer games. Afterwards he always rushed to the sideline to catch her changing out of her sweaty headset so that he could see her tits in her sports bra. He always made sure to get a hug too.

Every opportunity he had to say something to her or touch her non-threateningly he did. He helped her with homework. All under the nose of Sara who was oblivious to his intentions.

When Kim graduated high school, James went out and bought her jewelry in the color of her new school. He text her to come over because he had something to give her and she did.

When she walked in she was wearing ripped shorts and a low cut shirt. She gave him a big hug and asked what was up. He felt her tits against his stomach.

“Well we were on a tight budget this year, but I wanted to get you something special.”

He pulled out the necklace and she lit up.

“I love it! Here put it on” she tugged her long brown hair to the side and James got behind her. He looked down and saw parts of her ass in the holes on her shorts. He dangled the necklace around her and brushed his hands against her bare collarbone, then connected the necklace. James let his hands fall against her shoulders and he asked “how do you like it?”

She let her hair down and turned to him, looking down at the jewel of the necklace fell between her slight cleavage. James’ eyes followed hers and he imagined her tits in his hands.

“It’s amazing, you didn’t pick this out did you?”

“I did, but like I said we were short money this year so if anyone asks, your boyfriend got it for you”

She laughed, “So you’re my boyfriend now? Hehe just kidding”

“Our secret, promise” I said

“Whatever” she said with a smile then walked out, ass jiggling under her shorts.

Back in the room, James let Kim feel his erection against her leg as he traced his fingers down the curves of her hips. He slipped his finger into her panties and felt her wet pussy.

“I’m going to take these off” he said. Again Kim tensed and relaxed in one breath. “Yeah” was all she said.

As he pulled her panties off he could smell her wet pussy. He laid them on the blanket next to her, his fingers felt how wet the crotch had gotten. He looked down and at last, there was her thin, bald, pussy lips and the small hole they were no longer hiding.

He laid next to her and pulled his body against his own, then reached around the front of her waist.

  1. When the baby came, Kim had offered to take care of him the summer before college. Every morning James would meet her at the front door in his suit and tie, ready for another long day, because Sara worked the early shift as a nurse. Kim would always be wearing a long shirt that made it appear as if she wasn’t wearing any pants.

    A few times he came home to her sleeping on the couch. She would always manage to not cover up her ass, and in the shorts she wore James could see nearly everything. He would sit on the. Ouch and press lightly against her lower back to wake her up.

    He thought of those times as his hand slid from her bare lower back and sides to in between her legs. His finger sliding between her pussy lips.

  2. What was the main turning point? James thought. He knew Kim had been attracted to him from the get-go; he was a disciplined lifter and had “big shoulders and arms” which Kim and Sara both joked about often, of how hot he was.

    Maybe it was the previous summer when they were playing in the pool with Sara and two of Kim’s friends, one of which was a varsity football player. He was throwing Kim and her other girlfriend in the water, but wasn’t “launching them” as per their requests. Kim drafted James to throw her. And Being a pro at said sport of tossing women in the pool, he informed her that the best way was to sit on his palms and he would push her up five feet above the water. “No way” she said, bending over in the water and letting him put his hands on her ass. Sure enough he did, and proceeded to the rest of the afternoon. She looked fantastic in her Triangl bikini, her jiggly ass hanging out of the bottom, her little tits pushed up in her top, her flat stomach and dark skin. Maybe she realized then that her sister had landed a good one and started to envy.

    James was already set on getting her naked then, and was very glad he got to touch her ass so often that day.

    Maybe it was the lunch dates he’d take her on when doing business near her college- she’d talk about sorority life, the complexity of balancing school and fun, and everything else. James was an open ear. Sara actually told him how nice it was to take her to lunch. He knew from these meetings that he was getting her to open up in a very personal way.

    All of those were probably factors, but what really flipped the switch for her were the tickets to the autistic documentary he scored. James knew autism was her sorority’s good cause, so he mentioned that there was a documentary nominated for the Oscars about a kid with autism who learned to communicate through quoting Disney.

  3. James spread Kim’s legs further apart and continued to penetrate her with his fingers. With his free hand he pushed her shirt up her back as he rubbed her skin from her shoulders down to cheeks. He grabbed handfuls of her ass and opened up her pussy even more as he massaged them.

    He could feel her vagina’s walls lubing up as his fingers oscillated between the front and back of her pussy. His fingers felt the silk of her wetness as he traced the inside of her pussy with his fingers. James was getting extremely turned on watching her writhe on the blanket with her face tucked into the blanket. The air near her pussy was thick and sweet. He lowered his mouth to the inside of her thighs and began kissing her.

    James pulled his fingers out and pulled Kim by the hip to roll her onto her back. She laid with her legs spread and her knees up. He ducked down in between her legs with his mouth and started to tongue her clit. Kim had to bite the blanket to keep from crying out. Expertly James sucked on her clit, just nibbling with his front teeth. He let his tongue enter her and dance up, down, and circular in her sweet juices. With his hand he slowly traced from the top of her bald pussy, across her flat tummy, and up her shirt to grab onto her right breast. He was able to grab her entire breast in his hand and rub over her small nipples, which must’ve been sensitive because she let out moan of pleasure. He let the nipple fall in between two fingers and he massaged her tit as he ate her pussy.

    His other hand wrapped underneath her right leg around her thigh. She was absolutely soaked now and James knew she was about to come. He placed her clit in his mouth again, and pressed with the tip of his tongue harder than he had previously. She moved her hips, pressing her crotch hard against his face. James could feel her orgasm coming and thrust his finger back inside of her, pushing her over the edge. She almost screamed but bit down harder on the blanket and came. James sucked on her pussy drinking in her sweet juice, like biting into a fresh peach.

    James pulled his face from between her legs and moved up her belly, kissing her glistening skin. He got to her shirt and lifted it over her head. Her small tits were firm and perky, heaving up and down with the air filling her lungs. He felt her hands tug at his waistband, and he let her pull his shorts off. His cock was hard and pointing strait out when she got his shorts off. James removed his own shirt and the two naked lovers crawled under the blanket to burst through the wall of inappropriateness into dangerous territory together. Without worry or care of getting caught.

    Kim laid on her back and guided James tip into her slick hole. They locked eyes as their sexes joined and grinned devilishly.

    End of Part 1
