This is not some long drawn out, character build up story. This is an in your face, fuck me hard kind of story. The wham, bam, thank you ma'am kind of story that will make you cum hard. This is the story about Justin, his girlfriend and her step mom. Yes, that's right; you already know where this story is going. Are you ready? Are you hard or wet? Yes, I'm asking you, the reader. Good boy or girl, I know you'll thank me later.

Elena is the girlfriend and Stephanie is the step mom. Elena and Justin are in their mid 20s. Stephanie just married Elena's dad a few years ago. Elena was already in her 20s so yes; she's her step mom, but only on paper. It's not like she raised her. Stephanie is sexy as hell with red hair and 42DD breasts. She is sexy and not just at 40, but at any age. Her green eyes draw you in and hide her erotic, kinky nature and her curves are killer. Her body is dangerous and she knows it. She dresses provocative when she wants, but she mostly hides her dark side from others; they never see it when she's stalking her prey.

Elena is short, but she is top heavy to say the least. Damn is she top heavy and curvy as a West Virginia road. She loves to fuck a lot. She didn't know why Stephanie married her dad. Her dad is a good guy, but she knew that Stephanie was way out of his league. She always thought that it was about his financial status more than anything. Her dad was well off, not super rich, but they lived in a high end neighborhood and they never wanted for anything. He was a finance guy, boring really.

That was what she thought, until one night Stephanie had a long conversation with Elena. Her dad is way kinkier than she ever knew. Mom couldn't handle him, as it turned out. She never knew what happened, but her step mom knew and told her that her dad is a swinger. Not just that, but that he was into threesomes and many other kinks. That was too much info for her and then Stephanie went even farther and said that the reason she married him wasn't cause of any of that; not the kinks or his money, it was his swinging cock. Apparently her father was well hung, which Elena was immediately repulsed by, but she could appreciate at her age, even though she really didn't need to know any of this. All Stephanie had to say was that she loved him, end of story.

Why all of the extra sexual details she wondered? Stephanie did answer her unasked question by telling Elena that she didn't want to think that she was in it for the money and that she really did love him. But that didn't explain the sexual part of the conversation. Stephanie explained that as well; she told Elena that she was curious to see if Elena was like her father in that way and into any of the kinky sex stuff. At the time Elena laughed at her and told her no, absolutely not. It turns out that after a while, it was thought about and then acted upon, and Justin wasn't the first. Stephanie could see it inside Elena, buried deep inside her. She knew how to get it out of her. She saw the same in her father. Stephanie has a sixth sense of sexual desires.

Elena had broken up with a long term relationship and she started to go out partying a lot. She brought a new guy home one night and they were both pretty trashed. Thank God for Uber. Her step mom was up and just sitting there; she started to talk to the both of them and she was hitting on her guy. Stephanie was wearing lingerie. Why, she wasn't sure, but she didn't seem to mind it. She was pretty, Elena thought in an abstract straight kind of way, maybe even a little bit sort of way too. She could appreciate beauty when she saw it. Stephanie was all over this guy, he loved it too and Elena did nothing to stop it. She was mesmerized how Stephanie worked him like magic, a touch, a giggle. She could feel the sexual tension building up, she was even getting turned on by Stephanie; it was as if she had this sexual scent that drew you into her trap.

The next thing Elena remembered as she was quite drunk, and Stephanie was fucking the guy. Then she realized that she didn't even know his name. It was odd, surreal; it was like watching a porno except it was real and in her house. Stephanie was loud, like real loud. She wondered why her dad didn't hear or say anything at the time.

Stephanie sucked his dick like it was giving out gold. She learned a few things watching her fuck. Like how she licked and sucked him, like his cock was the best in the world. Stephanie knew how to make someone feel special. She even kept looking at Elena and it made her blush. Elena didn't want to join or even watch, but she couldn't stop either, she felt horny. It was really like a porn movie, even the premise of it. Guy takes home girl and fucks her and the step mom.

Stephanie made the guy eat her and finger her until she was dripping all over the place. She didn't tell him what to do, yet when she spoke you felt that you had to obey her. His tongue was long and he knew how to use it. They turned Elena on; she was fingering herself on the chair while she watched them on the couch. She started to moan and Stephanie smiled at her and blew her a kiss. She couldn't help but to pleasure herself while watching them fuck, like a porno. Stephanie's moans were enchanting, songs of a siren driving you to crash into her trap and you loved it.

Elena wondered now just what her dad was up to sexually. Not that she really wanted to know every detail. He had to know what was going on now. She wondered how he could be ok with his wife fucking other men and maybe even her. It wasn't incest and she wasn't raised by her. They didn't get married until she was already an adult, but Stephanie was still technically her step mom. She was too drunk to figure any of this situation out and she didn't know why she was thinking about their conversation from a long time ago, especially since she was cumming to Stephanie fucking a guy she was supposed to be fucking.

Elena watched Stephanie fucked her man six ways till Sunday. He wasn't really her man, just a one night stand, but still. Elena just wanted to see what would happen and she was certainly seeing it now. Her step mom was a freak in bed and was even doing things to try to get Elena to join, but she was too drunk and too afraid. Elena was just enjoying watching and cumming to the both of them. The new guy was an athletic specimen. His cock was rock hard like his abs. He was beautiful just to look at. He was also very good at what he was doing to her step mom, the two of them together looked perfect. Stephanie looked like a sexual Goddess, her long, flowing, dark red hair and her big, beautiful round breasts with perfect pink nipples and that little bit of fire red strip of hair that went down to a pretty pink pussy. She was enamored by her beauty. Sex seemed to permeate the air around Stephanie. It was like her pheromones were powerful and that she was really an enchantress.

Stephanie had waited for this opportunity to bring Elena's dark side out of her. Even though she was only watching her fuck this new guy, she was fingering herself to them and that turned her on. Now it was only a matter of time before she joined them. This new guy was great in bed, but the real prize was sitting on the chair: Elena.

Stephanie wasn't sure what brought Elena to this point. Maybe it was the alcohol, maybe Elena wanted to see if he would fuck her step mom, maybe she was turned on by it. Stephanie didn't know why, but she did know that Elena was coming around to it. She'd have sex with her soon enough. She was having fun with this young man. He had a good sized cock and his body was strong and he could last a long time too, but that could have been the alcohol as well.

Stephanie really just wanted Elena to join. She wanted to see her naked and taste her. She was young and pretty and she looked kind of like her. She reminded Stephanie of herself in some ways. She wanted to mentor her, show her things she didn't know when she was that age.

Finally, the young man was about to cum and Stephanie let him cum inside her, Elena was shocked. Stephanie loved the look on Elena's face as she watched her fuck her friend, all while she was fucking herself and cumming too. Stephanie thought it was sweet to watch and listen to Elena's orgasmic melody. She asked Elena if she was horny and she shook her head yes. Then she asked her to kiss her. The boy of course was turned on by this idea and told her to do it. That just made Elena nervous. Stephanie kissed the younger man and thanked him for the sex, but told him to be quiet and watch; he did as he was told. He still had Stephanie's sweet nectar on his lips from earlier, not too bad.

Stephanie was naked and got up off the couch and sat on Elena's lap on the chair. She kissed her, Elena froze, unable to move, she was stunned. Then she let go and let her step mom take control. It was a sweet release, blissful, euphoric and she was lost in the ecstasy of the entire thing. All Elena wanted to do was to be used by the both of them.

Elena had very little recollection of what happened that night when she woke up the next day. She felt like she was hit by a truck and her panties were soaked, she wasn't sure if she had sex with that guy or her step mom or both. It felt like a dream. She didn't even know his name and didn't have his number in her phone so she couldn't ask him what happened. Elena wasn't much sure that he would even know. She wasn't sure if she should ask her step mom because what if it was a dream and it would make things weird. It felt like a weird dream and maybe it was. Stephanie acted like nothing at all happened. She never mentioned anything. She did smile at her all the time now though.

Elena did remember the conversation they had a long time ago about weird sex stuff with her father and swinging and how she wanted her to be in that life. Maybe she dreamt what happened last night or maybe she wanted it to be true. The whole step mom porn thing maybe. She wasn't sure what the fuck happened last night and was too afraid to ask Stephanie because what if it didn't happen? It would be an awkward conversation to have. But...what if it did happen? Then what? She didn't even know what happened if anything. And if it did happen, what would they do about it now?

Time went by and Elena met Justin. The story where this all began, the entire point of this erotic tale, the last part was the set up. You know the people and the background.

Now, the real sex story begins:

They had been going out for a few weeks and she really liked him, but she was reluctant to have him over at her house. She was afraid of what might happen. Justin had insisted that if they were going to continue their relationship, then he wanted to go to her place and meet her family. Elena did invite Justin over against her fears; she couldn't tell him what those fears were. He met her dad and her step mom. The first time he came over, it was a normal dinner; Stephanie didn't try to fuck him and Dad wasn't trying anything weird either. Elena figured that maybe it was all in her head.

She and Justin were a thing now and he would come over often, it was like his second home. Then, Elena thought she saw Stephanie flirt with him a few times; a touch on his shoulder, she laughed at his jokes. He didn't seem to notice and dad would just watch. Then he would talk to her on the side.

It was suspicious, but nothing weird. She did keep an eye on her step mom when she was around Justin. Elena didn't say anything to Justin because she didn't want to explain why she felt this way. More time went by and now it was a month of him visiting their house and nothing happened; just her usual touching his shoulder or his thigh, Stephanie would even sit next to him. Elena wasn't completely over her fear, but she didn't think that anything would happen either. She was more relaxed, it probably was just all in her head.

Maybe it was a weird sick fantasy. Stephanie and her dad may be swingers and that was ok, but it didn't mean that her step mom was trying to fuck her boyfriend.

Stephanie wasn't sure why Elena hadn't said anything about that night. She acted like nothing happened, a lot happened and it was good, better than good. Elena wasn't her first girl, but it had been her first younger one. She wanted to mentor her; to teach her how to use her sex for power, maybe Elena was embarrassed. She wasn't sure, but after awhile she brought this new boy around and she wanted to get him. Tom was ok with it. Elena's dad wanted her to do it. He said he could hear them fucking that night. She didn't tell him that she fucked his daughter too, not now and not ever probably. That may be too much for them, she didn't want to ruin a good thing.

That night was special. That boy was a good fuck, but Elena was special. She was soft to touch and to kiss. She knew she was drunk and she asked her if it was ok. Elena agreed to it. In fact she was supposedly never been with a girl before, but she fucked like she was with many before. Stephanie remembered how Elena kissed her, fingered her and ate her out. Elena was incredible. Everything she wanted and more. The night for her was more than she dreamed of, but then Elena acted like it never happened and it broke her heart.

Stephanie reminisced about that night:

They ended up on the floor. She undressed Elena and ate her out. Damn she tasted so good. It was all she could think about now and how Elena could use her fingers and that tongue so masterfully. Elena had her on her back and she ate Stephanie out until she was screaming and begging for more. Then that young man fucked Elena from behind while the girls kissed and fingered each other. Stephanie even made sure the guy pulled out and came on her instead of inside Elena.

Stephanie was under them while they fucked. Elena didn't even seem to care. She was too busy enjoying Stephanie kissing her pussy and his cock and how Stephanie was grabbing her boobs and sucking on her nipples. Stephanie remembered how Elena moaned while getting fucked from behind and how her 48DDD breasts swayed and bounced into Stephanie's face while she sucked on them. When she knew that the guy was about to cum, she slid down further and pulled out his cock and finished him off onto her chest. Elena sat on her face; semen was all over her breasts. This guy was still semi hard and he started to fuck her again. He was young and full of raging testosterone; she didn't think he would want to go at it again so soon. She also remembered how sweet Elena tasted that night, so sweet, like candy. She wanted to eat Elena rotten; she wanted to ravage her pussy and her body.

Stephanie was enjoying it all. Elena got off of Stephanie's face and rubbed the sperm between their chests. It was the hottest thing ever to Stephanie. They were kissing so full of passion after. Their mouths felt electric sparks between them and then they each licked the jizz off of their boobs while the guy was still trying to fuck Stephanie on her back. Her and Elena kissed and fingered and ate each other the entire time. Elena even 69'd her while he was fucking Stephanie and she even sucked his cock too. He came down her throat and then she kissed Stephanie and spit some of the semen into her mouth. It was the best sex Stephanie ever had and Elena acted like it never happened. How? Why? What went wrong?

Now that Justin was coming over regularly, she wanted to see if she could reenact it all, if she could get him alone. She would flirt with him, but Justin seemed oblivious to it all; that was until the day he stayed while Elena had to go out. Justin was good looking, not like the first guy, but he was sweet and kind. There was something special about him. She had her sexual sixth sense about Justin and she wanted to fuck him and Elena.

One day Justin came over and Elena had to go out for a bit and she told him that he could stay there. Her dad and step mom were ok with it. Justin seemed at home; they had a big house and a workout room where he would work out when he was over. Elena figured it would be all good; she would be back in a few.

Stephanie knew that this was her opportunity, they would be alone. Tom went up stairs and she got her sports bra on and her tight yoga shorts. Justin was in a white tank top and his basketball shorts. Tom said it was ok for her to try to fuck Justin as long as she told him all about it. Tom owed her from the other night when she let him have a threesome while she watched at a swingers club.

That is a different story altogether. I will have to write more about Tom and Stephanie's sexcapades in another story. I know you want more, but you'll have to wait. Let's just say that Tom got to cum in more than one girl and watched them have sex while he joined them all while Stephanie watched. So, yes, he owed her this much. Maybe not fucking his daughter, but he didn't need to know that just yet. It was her dirty little secret; she didn't want to ruin a good thing. Maybe one day she would tell him.

Justin was already working out when Stephanie came down to work out. He was lifting on the bench and she was doing some stretches. Justin noticed how hot Elena's mom really was, he kind of thought that she was hitting on him, but he figured it was his fantasy and it was all in his head. He was about to find out otherwise.

Stephanie was stretching and bending over so that he could see. She was in short, tight yoga shorts that you could almost see her pussy through. Her nipples were almost popping out of her top. He watched as she bent forward and he had a view of her huge breasts.

She was smiling when she got back up and adjusted her boobs. Justin knew that he was getting hard just watching her; she was gorgeous, it was wrong to see her that way he thought. It was technically his girlfriend's step mom. Yet, he couldn't help but get an erection when any sexy woman was doing the things that she was. For God's sake, she was adjusting her boobs right in front of him.

Stephanie smiled and laughed. "Be thankful you don't have these large breasts to deal with Justin, they can get in the way. Oh...ummmm...sorry about...you know. I can't help it."

He knew what she was talking about. Her nipples were hard and he was embarrassed and blushing. Now that he noticed and looked down, he could also see camel toe. It was as if she wanted him to see it all, maybe she was, but what could he do about it?

"It's ok. Umm...I don't mind. I mean...not like that. Not that you're not hot. No, not that. I mean that I get it. It's ok. That...you know...ummm... yeah." Stephanie knew she had him; he was really blushing and shy.

"It's ok Justin. I know Elena looks better than I do." She was totally fishing for a response and she got it.

"You're sexy too...uhhh...I mean. Elena is hot, yes. But you're pretty too. Not that I umm...you know. God I'm sorry, I'm so embarrassed. You're her mom."

"Step mom. And it's ok Justin, to see another pretty girl and recognize it, nothing wrong with it. It's not like I raised her either. I'm glad you think I'm sexy, your words. You're not too bad yourself. Why don't you relax and take off your shirt. You're a man; it's ok to work out without your shirt here."

She was laying it on thick; she could see him getting super hard. He was hers, all she had to do was find the moment to take him and make him hers before Elena came back and then she could get her involved like the last time. Justin was just a means to get back to Elena; that was her prize and if Justin was a part of getting it, then so be it. It's not like he wouldn't get to enjoy the benefits of it all.

"You sure? I guess it can't hurt."

Justin sat up on the bench and took off his shirt. He wasn't super fit, but he was still cute. It was nice to see a real man and not some guy who only worked out and cared more about himself than anyone else. She knew that he was a sweet guy too; it would be fun to fuck him. Plus, it looked like he had something special in his shorts.
