Sorry, it's been so long I have been busy with life. All parties are of legal age that are involved in sexual interactions. This one will be told from two separate viewpoints, mine and Alex's as she told it to me after I confronted her. I will tell you when they switch before starting into the new viewpoint
Joe.
Ok, I guess the first thing you should know is my father had a sexual relationship with Alex but never Bess, and parts of this story I am telling as it was told to me. Like I have said before sex with Alex was nothing more than sex at least for me. I would learn it meant more to her only after finding out about her and our father.
The thing is since it was just sex for me I never tried to mistreat her or take advantage of the situation but I also didn't always pay attention to more than both of us getting off. After our father reappeared in our lives Alex and I moved in with him for a short period to try and get to know him which Bess wanted nothing to do with him. This meant I went from getting laid multiple times a day to about once every 2 or 3 days so I wasn't exactly thrilled with Alex though it wasn't her fault.
Now the house our father lived in at the time was with his new wife (which unless we were talking to her we just called her she), her parents, and one of her brothers so there seemed to always be someone around no matter the time of day or night but we still found time to fuck when we wanted. I will be honest and the first to admit I am the one who messed up and got things started for Alex and our father even though she was a daddy's girl from day one. Things didn't happen in one day but I will go from the beginning to the end but I won't give a timeline of how much time passed from one incident to the other because it is not important for the story.
We had been living with our father for a short time so I was frustrated from not having sex like I had gotten used to since Bess was still with our mom. It was summer so it wasn't unusual for Alex and me to be at the house alone if we didn't have work that day. Somehow this Saturday we both had off so it was around lunch when I ran into Alex coming out of the bathroom in nothing but a towel after taking a shower. Seeing her like this just made me even hornier than I already was so I made a move to try and start things. The thing you need to know is our stepmother was OCD over certain things and one of those was the water bill so she made sure we didn't wastewater.
"Alex, what are you about to do?" I say while pulling her close trying to undo her towel.
"Joe not right now I just got out of the shower and have plans later so I can't afford to get dirty right now but maybe later after I get back," Alex replies, pulling away holding onto the towel.
"Come on nobody is home so no one will know you had a shower already today," I tell her as I once more try to remove her towel.
"Yeah I know but she saw me getting in as she was leaving for work so someone does know," Alex informed me once more pulling away barely keeping a hold of her towel.
"Come on it's been a few days and you are sexy as hell standing there with nothing but a towel covering you. See how hard you have gotten me already." I plead as I place her free hand on my steel rod.
"Joe, I have plans later with my friends and can't take another shower today without upsetting her if she finds out. So you will just either wait or get it from someone else." She says as she turns down the hall.
Before she makes it to her door I once more grab her turning her back towards me saying. "We don't have to make a mess to have fun. Ok, we might be a little sweaty afterward but that you can say is from going to the gym. I promise that I won't make you a mess. I just really want you right now please."
"Alright, Joe but you also can't be rough. I don't want to be sore all day long. Honestly, I am also horny but every time you fuck me we are a complete mess afterward and I can barely walk for a little bit right after we finish. So as long as you promise I guess it will be fine if we do it right now come on in my room big brother." She finally says giving in to my desire. Now, this is where I would mess up with her which would open the door for her to start fucking our father later on.
Things would start well. I took my time. I was gentle and caring and did the things I normally wouldn't do with her and avoided those things that were dominating in nature. I started by kissing her and making out with her as I removed her towel leaving her naked and open to my lust. I would make my way down her body leaving little to no trace of where I touched her as I went. I even made sure as I ate her shaved bare pussy to keep juices from getting everywhere as much as possible.
I got her through her first orgasm. I then let her mount and ride my cock so she could be in control. She did this until she came once more and collapsed on top of me exhausted from the effort but before I had cum or was even close. So I rolled us so I was on top and started to pound her driving towards my release.
"Joe, please you promised and it has been so nice, don't ruin it now." Alex pleads as she comes around and gets enough air to speak.
"Alex quit complaining I got you off twice already let me do what I need to now so I can get off once," I remark as I continue to drive my cock in and out relentlessly.
"Ok, Joe just remember I can't be a total mess cause I am going out with my friends later." She whines giving in to my lust and mistreatment.
Now I know it shouldn't but that pisses me off cause how dare she. I already did what she asked why can't she just let me have a little of what I want as well. Then as I smile realizing how I can not only make it a point that she doesn't control me. As well as keep her from getting in trouble I make my mind up on what I am going to do just as I am getting close. Just as I begin to explode I pull out spraying my semen all over her the first couple of spurts land in her hair and on her face the last couple leaves a trail down her body wiping my spent cock on her pussy putting the finishing touch on making her a mess.
"Joe you asshole. Why did you do that to me knowing what we agreed to before we started? Now I either have to take a chance of getting caught taking another shower or a long shower." She says as her eyes fill with tears.
"Or you can just come to take one with me so if anyone says anything the first one was you and the second was me so we are both covered," I say smirking at the thought of getting a little more from her in the shower.
