The morning sun was shining through Eddie's bedroom window. He had just wrapped up talking to his wife, Susan, who was away on business. She had sent him some pics of her showing him what she was doing in his absence. He responded in a flirtatious manner, but knew he couldn't do anything about it given his morning meeting in a couple of hours. He told her he loved her and went downstairs, adjusting his tie.

When he got to the kitchen, he saw his step daughter Krissy. She looked a lot like her mother. Tall, big breasts and a nice ass. Her red hair was lighter than her mother's and Susan had a curvier figure. Still, he had made the mistake of mixing up the two from behind. There was no such mix-up this morning with the wife out of town. Krissy was wearing a red t-shirt that barely covered her ass and a lacy black thong. She stood at the counter with her back to Eddie as she drank some orange juice.

"For Christ sake, put on some clothes," Eddie said, walking over to the coffee maker.

Krissy just smiled and pranced over to the breakfast table. "Oh come on, Eddie," she said. "It's no different than me wearing a bathing suit."

Eddie poured his coffee into his mug. "Your bathing suit isn't showing off your ass cheeks," he said.

Krissy giggled. "It could if I wanted it to," she said.

Eddie rolled his eyes and looked over his notes before filing them away in his briefcase. Krissy watched with curiosity. She knew he had been working on a novel as of late, but he was not very open about what it was about. She decided to ask.

"So, what is your story about anyway?" she asked.

Eddie thought for a moment, considering how to answer. He decided to be honest with her. After all, she was 18 and a few months away from graduation, why not? 

"It's called The Affair," he said. "It's about a lonely woman who is unhappy in her marriage and she starts seeing another man who turns out to be a spy." 

Krissy's got wide. "Oh, that sounds cool," she said. "But, why all the secrecy?" 

Eddie paused with his answer. "There is a very graphic sex scene in it," he said. "Not exactly for young eyes." 

He locked his briefcase and began to leave. "I'm meeting with my publisher, Regan, this morning," he said. "I should be home around dinner time. Order us some pizza. It will be just you and me tonight. Your mom is probably going to be gone all week."

Krissy nodded and watched him leave, taking in everything about him. She could see why her mother was so taken in by him. He wore a suit well, had great hair, with a beard that presented a distinguished presence about him and he was in great shape. She finished up her juice and went upstairs to shower after Eddie pulled out of the driveway.

Eddie returned home that evening and for the most part, everything was a typical weeknight in his household. He and Krissy talked about the day and how his meeting went while eating pizza. Afterwards, Krissy retreated to her room and texted some friends while Eddie continued working on his novel. He turned in just after 10:30PM.

Meanwhile, Krissy tossed and turned in her bed. For reasons unknown, she could not go to sleep. She was restless and horny. It didn't help matters that her thoughts were focused on her stepfather. She got out of bed wearing the same t-shirt she had worn that morning. However, she was sans panties as she liked to have little on while in bed. She crept into the hallway and peered into her parents' bedroom. The desk lamp dimly lit the room, but Krissy could see Eddie laying on the bed. He was naked and on top of the covers.

She felt herself get aroused by this sight and reached under her shirt to massage herself. "This won't do," she thought after rubbing her clit for a minute. She snuck into his room, almost tiptoeing to his bed. She climbed on it and gazed at how big Eddie's cock was, even being limp it was impressive. She looked at him; he was out cold. She took her tongue and glided it along Eddie's shaft. It responded. Krissy licked it a few more times until it was fully erect. She sat there in amazement of this 10-inch cock in front of her. She felt herself getting extremely wet. She wrapped her lips around it and began sucking it. Krissy took in the taste and became increasingly turned on knowing this was only the second mouth to touch Eddie's cock besides her mother's.

She couldn't take it anymore and decided to do something bold. She pulled up her t-shirt and straddled Eddie. Easing herself down on his cock, she let him all the way inside of her and began riding him. Eddie began to stir, but was in a very drowsy state. "Fuck me, Krissy," he said sleepily. Krissy continued riding him, her pussy responding to his words. After a few minutes, Krissy felt a load of cum being shot inside of her. She placed her hand over her mouth to muffle her moans; her pussy reacting to being filled up and her own orgasm washing over her. Eddie stirred some more and as Krissy got off him, she whispered, "It's just a dream."

She scampered off to her room, with Eddie's cum running down her thighs.

The next morning, Eddie awakened and he had a feeling something wasn't right. He saw evidence that he had cum last night, but couldn't figure out why. He didn't jack off. He was damn sure he didn't have a wet dream, although he seemed to remember a weird dream involving Krissy. He put on some shorts and a t-shirt and went downstairs. 

Krissy was sitting at the breakfast table in a tank top and boy shorts when Eddie entered the kitchen. He looked at her. She returned his stare. Her face soon gave away the truth.

"Krissy, were you in my room last night?" Eddie asked.

Krissy was uncertain on how to respond. Before she could speak, Eddie interrupted her.

"Let me guess, you snuck into my room and fucked me while I slept, didn't you?" he asked.

The 18-year old redhead nodded with a degree of guilt on her face. Eddie shook his head. "What the hell were you thinking?" he asked. "Do you realize you might get pregnant?"

Krissy's face turned to that of fear. The last thing she needed was a baby and to have one with her stepdad would be unforgivable. "I'm sorry," she said, tears welling in her eyes. "I was horny, I saw you and I didn't think."

"That's my excuse around here, young lady, not yours," Eddie replied.

Krissy sat in silence. Despite the shame and guilt she was feeling, she still found herself hopelessly attracted to the man who had a hand in raising her for 15 years. "You did tell me to fuck you, you know," she said softly. Eddie paused a moment to let the words sink in before he left the kitchen and went upstairs. Krissy's eyes followed him until he was out of sight.

Eddie got in the shower, his thoughts running wild. He didn't know what to think really. He was trying to come to terms that his stepdaughter had fucked him while he was asleep and he came inside her. "What the fuck?" he thought. "Did I really tell her to fuck me?" Eddie asked himself. He found himself conflicted given the nature of his role as a parental unit and a subconscious attraction to the teenage vixen living under the same roof.

Something in his peripheral vision caught his attention. It was Krissy. "What are you doing here?" he asked. 

Krissy got undressed and stepped into the shower with him. Putting her arms around his neck, she looked into his eyes and told him how she felt. Despite his best efforts to resist, Eddie became aroused. Krissy looked down and then back up at her stepfather with a wicked grin on her face. She dropped to her knees and proceeded to give him a blowjob. Eddie closed his eyes and moaned. Part of him wanted her to stop; the other wanted her to keep going. She was really good for being as young as she was and he filled her mouth with cum in a little over five minutes. She looked at him and she made sure he saw her swallow his load.

Standing up, Krissy gave Eddie a kiss. 

Then, the voice of Susan, startled both of them.

"Hey, you two, I'm home!" she yelled from the downstairs foyer. 

"What the fuck are we going to do?" Krissy hissed. "She wasn't supposed to be home until the end of the week."

Eddie stepped out of the shower and grabbed a towel. "Stay here, get cleaned up and don't get out for about 10 minutes," he said before exiting the bathroom.

As he went into the bedroom, he responded to Susan downstairs. "Hey baby, I'm up here getting dressed. Krissy is in the shower. I'll be down in a moment."

Eddie put on a pair of sweats and a t-shirt before making his way downstairs to meet his wife. Susan was in the kitchen and looking over the mail when he came in. "This is a nice surprise," Eddie said, walking over to her. "I didn't think you would be back until Friday." He kissed her. Susan reciprocated the affection, their tongues exploring each other's mouths. 

"Oh honey, you know how good I am," she said, looking lovingly in his eyes. "I was able to get an earlier flight back and here I am."

Krissy emerged several minutes later in a pair of blue jeans and a white shirt that was very flattering of her figure. She hugged her mother and the two of them caught up on what had happened while Susan was out of town; well, almost everything.

A Few Weeks Later

Krissy and Eddie didn't talk about their shower encounter or what she had done to him in his sleep for several days. Susan being home helped reduce the awkwardness and alone time between them. One night, Susan and Eddie went out. When they returned, Krissy was asleep in her bed. The couple engaged in steamy sex and in an effort to last, Eddie popped some dick pills. This decision would change things forever.

Susan went to her daughter's room and knocked softly on the door. Krissy murmured a bit and opened her eyes a bit to see her mom standing in the doorway wearing just her satin robe which went down a few inches past her ass. Krissy could see it was open. She sat up, wondering what her mother was up to at this hour.

"Eddie took some pills to last longer," she began. "And this is embarrassing, it worked. But, my pussy and ass are sore and I was wondering if you could help me." she asked.

Krissy looked confused.

"How can I help?" she asked.

"Krissy, I need you to fuck him," she said. "I wouldn't ask this of you if I didn't think you weren't ready."

Susan extended her hand out to her daughter. Krissy got up out of bed wearing her pink tank top and black thong and took her mother's hand. The two walked back into the bedroom where Eddie was laying in bed stroking his cock.

"What's going on here?" he asked. 

"I told Krissy about our situation and she has agreed to help us out," Susan said.

"Go on, babygirl. Get in there!" Susan sat down on the chair a few feet from the bed and began watching. Krissy learned about her mom's voyeur kink that night as well as her willingness to share her husband.

Krissy climbed onto the bed like she had one a few weeks prior and took Eddie's cock into her mouth. Unlike last time, he was awake and very much aware of what was taking place. Krissy slid her tongue up and down his shaft, licking his shaved balls and taking every inch of his cock into her mouth until she was at the base of it.

Eddie closed his eyes and groaned. "Holy fuck, that felt good," he thought. "Keep doing that Krissy," he said, holding her head. 

Susan watched intently and found her pussy getting wet by watching the scene unfold in front of her. She opened up her robe and started rubbing her pussy. Eddie looked over at her, excited that his wife was getting into this. His wife and stepdaughter looked damn near identical from their red hair to curvy physique. The only difference was Susan had bigger assets and a well-manicured landing strip above her pussy while Krissy was clean shaven.

Eddie helped take off Krissy's tank top, revealing her big breasts. She had never been fucked between her tits before and wanted to try it. Eddie helped her by holding his cock in place while Krissy held her breasts together, letting the shaft slide between them.

"That's fucking hot," Susan whispered, fingering herself.

Krissy giggled at the sensation but found herself becoming extremely wet. She stood up in front of her mother and slid her thong off. Then, she got on all fours as Eddie got behind her. He spanked her ass after caressing it for a few seconds.

"Ohhhh!" Krissy yelped. "Mmmmm...do it again, daddy."

Eddie obliged and left a red handprint on her right butt cheek. Krissy looked over at her mother and smiled. At that moment, Eddie entered Krissy. 

"Holy fuuucckk!!" Krissy moaned. She had never taken a cock that big before. Her first time involved a guy who was about four inches. The average size she got was no bigger than six inches. Even her dildos weren't that big. 

Eddie pumped slowly into her, letting her pussy get used to the size. When she was taking it easily, he began thrusting faster and harder into her. Krissy's breasts jiggled back and forth as she was fucked from behind. Her moans of pleasure echoed throughout the upstairs and could be heard almost throughout the entire house. Susan watched as she had disrobed and was furiously finger fucking herself.

"Ohhh fuuck," Krissy whimpered. "Yes, this feels so good."

She squealed her approval several more times before Eddie pulled out. She marveled at the size of it, just standing erect and proud for all to see. She understood why her mother was always pleased sexually. Her stepdad looked at her. Taking the non-verbal cue, Krissy lied on the bed, her legs spread. Eddie positioned himself between her legs and lifted them up as he slid himself inside her. Susan moved onto the bed herself at this point because her view was obstructed by her husband's backside.

With both of Krissy's legs resting on his shoulders, Eddie slid himself into her shaved pussy, stretching her out. "Oh god, yes!" she moaned, lustfully. It wasn't long before Eddie was fucking her hard from this position, his balls slapping against her womanhood. Krissy could feel her juices dripping more than usual. It wasn't uncommon for her to soak the sheets when she masturbated with her toys, but this was different. Of course, taking the biggest cock of her life would result in this.

Eddie's cock became rigid and his balls began to tighten. As he pulled out, Susan recognized this and helped her daughter up. Eddie stroked his cock in front of his wife and stepdaughter for several seconds before a rope of cum streamed across both their tits. 

"Oh shit," Krissy exclaimed. She knew it would be a lot but that exceeded her expectations.

Eddied grunted, jerking his cock some more and squirting another generous load of cum onto them. 

"Holy fuck," Krissy exclaimed. "It's like this all the time?" she asked her mother.

Susan smiled. "With him, yes," she said. "Not so much with everyone else."

Krissy held her breasts admiring the mess on them. Susan stroked her hair back looking at the mess Eddie made on her daughter before admiring the load deposited on her. 

"It worked," Susan said to Krissy, nodding in the direction of Eddie's cock as it went limp. "You did great, babygirl."

"That was amazing, Krissy," Eddie said, as he kissed her.

The three of them jumped in the shower and got cleaned up before retiring for the night. Krissy had a difficult time sleeping the rest of the night. The events of that night swam in her head and how it made her feel had her heart pumping in a way she had never felt before. Eventually, she went to sleep, but not before taking a vibrator to her pussy, replaying her stepfather's touch in her thoughts.

The next morning, Krissy went downstairs for breakfast. Her mom was sitting at the table, drinking her coffee. Krissy poured herself a glass of orange juice and joined her. Susan put her hand on her daughter's arm as a sign of reassurance. They sat there in silence for a couple of minutes.

Susan looked at her daughter. "Babygirl, I know you have had eyes on your stepdad for awhile now and he told me about what happened when I was on my last business trip," she said. "We don't keep secrets in the household. In fact, Eddie and I have an open relationship."

Krissy's eyes grew wide at this revelation. 

"If you want to spend intimate time with Eddie, just be upfront about it," Susan continued. "No secrets, ok?"

Krissy nodded as her mother got up and washed her coffee mug. 

"We'll talk more about this when Eddie gets home this evening," she said.

Krissy smiled. She thought her mother would kill her for what she did to Eddie while she was out of town. Now, in a span of less than 12 hours, she had been invited into their bedroom, fucked Eddie while her mom watched and received her blessing to continue engaging in sexual acts with him. Things were looking up for the young nubile.

They were, as this was...
