A couple of years back when I was around 20 years old, my brother had invited me and my stepsister over to his place for a week. We had gone back and forth over this plan just as any other plan and finally decided to do it.

The age difference between me and my stepsister was around 15 years. So she was 35 back then and had a 8 year old kid. She's a MILF and very attractive one. As a kid I always used to wonder what she'd lol like without those clothes. Though she was attractive she never dressed well.

A few weeks later, we packed up, hopped on a flight and left to Texas where my brother lived. It was just me, my stepsister and her kid going on this trip. It was a 8 hour flight and although it wasn't that long we were all pretty exhausted so we passed out right after we reached our brother's place.

The sleeping situation there was kinda messed up. There were two floors in the house; ground floor has one bedroom where my brother and his wife stayed and the first floor had one bedroom in which me, my stepsister and her kid had to stay. There was one bed on which my stepsister and her kid slept, I got an air mattress on the floor and had settled comfortably on it. The first night went quick before any of us could realise.

The next morning we woke up a bit late around 11 and went out for lunch. We had gotten around the area and went to a few places. We were a bit tired from roaming around for hours so we thought we'll all maybe watch a movie together and hit the bed.

Halfway through the movie my brother and his wife wanted to go to bed as they had to work the next day. So me and my stepsister decided to finish the movie and then go sleep. The movie got over and neither of us felt sleepy. We stayed up talking about stuff. My stepsister was divorced and didn't have any sexual partners for the last 9 years. She was talking about how not being able to release the sexual tension affected her on a daily basis. I felt for her. I told her that for a person like her getting another guy shouldn't be hard. She's literally got everything a guy wants in a girl. She's nice and has an amazing body. She's got pretty big boobs and a huge ass. She wears clothes that's don't compliment her looks although she wears em tight so it's easy to understand what's going on underneath.

When I told her she's one of the most beautiful people I've met and that she shouldn't struggle like this, it made her happy. She got close to me and put her head on my shoulder. I then asked her if no one ever approached her. She looked me in the eye and told me that "Even though there were people, I never felt anything with them. They weren't sweet or nice to me. It felt as if all they wanted was my body and my money. Nobody understood me and I never wanted to give myself up for anybody who didn't see who I was." I told her that I understood how she felt and that I see her for who she is. She held my hands as she was laying on my shoulder. I felt her tears run down my arms. I pulled her up and told her that I am and always will be there for her. She kissed me on the cheeks and said thanks.

Later we decided to go to bed. Around midnight I woke up to get a glass of water to drink. I realised she was awake as well and was using the restroom. I went down, drank water, came up and lied down again. It was over 30 mins since i saw her go in and she didn't come out yet. So I went near the bathroom door to check if everything is alright. The door was open. I knocked twice and went in to find my sister naked and touching herself. I apologized to her for walking in and I left. A few mins later she came out and lied down on her bed near me. I felt her have run up and down the side of my hands. I asked her if everything was alright. She immediately got down to my bed and hugged me tight. She came in to kiss me on the cheek but I didn't know what she was doing so I turned. She ended up kissing me on the lip for a quick second before she realised and pulled back.

She apologized but i was startled. I always wanted this but now that it was happening I didn't know what to do or say. I didn't wanna say the wrong thing and screw with my chances. I stayed quiet as she got more anxious about how I'd react. I held her tight and told her to calm down. I told her it was fine and as a joke said that she could make out with me anytime. We both laughed for a few secs till it turned serious. She looked back at me and told me I was handsome and came close to me as if she was leaning in for a kiss. Not knowing what to do I went all in and we ended up making out. It was awkward at first. We pulled out of the kiss and kissed again for a while until we got pretty comfortable with eachother. She ran her hands down to my dick and tried to pull it out while I played with her ass and boobs.

I then lifted her shirt and sucked on her tits. She had amazing boobs that were perfect to play with. She pulled my dick out and slid it into her pussy which was surprisingly tight for a woman who had a kid few years back. It felt nice and warm and the fact that I was fucking my stepsister while her kid was sleeping on the other end of the room made it even better.

She pulled me in for a kiss while riding my dick up and down. I then pulled my dick out and got above her. I started fucking her tight pussy hard and didn't stop. She controlled her moans and tried not to wake anyone up. The kissing helped reduce the moaning a bit. I ended up blasting cum right outside her pussy. I then went down on her and made her cum in a few mins. I fell back on the bed and we started making out for a couple more minutes. We then got up and cleaned ourselves and changed. She spent the entire night on my bed right next to me. We feel asleep in eachother's arms.

From being step siblings to becoming lovers our relationship had taken a new route to explore many more things together.
