By the time I woke up, Rachel was gone. Was she also embarrassed at what she felt? I checked my phone and there was a message from her.
"Sorry I left so early. I forgot to do something for mom yesterday so I thought I'd better do it soon. Thanks for the bed. See you around."
It was a couple of weeks later before I saw Rachel again. I was busy with work and she was busy with school. She called me in my way home from work around 5pm crying. She said she caught her boyfriend cheating on her and she broke up with him, heartbroken. She asked if she could stay the weekend with me because she couldn't deal with our parents. I told her it was fine.
I ordered her favorite pizza once Rachel showed up. She was a mess. I let her cry on my shoulder as long as she needed. She finally dried up when the pizza arrived. We ate and I tried to crack jokes to make her feel better. After we ate, I put her favorite show on Netflix and we started to binge watch. She was cuddled up to me and would say something or cry a little bit every now and then. I'd hug her and kiss her head and told her I'd kick his ass for hurting my little sister. She laughed at that and didn't cry any more.
She decided to change clothes. She usually kept some clothes at my place but she came out wearing on of my t-shirts. I'm not sure if she had shorts on or not because the shirt went down to her mid thighs. I know she didn't have a bra on because I could see her nipples sticking out. I felt myself getting hard and I tried not to look but it was too difficult. She came back onto the couch and cuddled again with me. She kissed my cheek and thanked me for being a great big brother.
Rachel ended up falling asleep and I carried her to my spare bedroom. When I picked her up, the shirts raised up and I saw she had a thong on. I covered her up and went into my room. I was hard again but decided not to masterbate. I just took my shirt off and went to sleep.
Sometime later, I felt someone get into the bed with me. Being asleep, I thought it was my girlfriend at first until I heard, "can you hold me please? I don't want to be alone." It was Rachel. I threw the covers over her and put my arm around her, from the outside. She moved closer to my where we were basically spooning. I wad getting hard again and there was no way she didn't notice. She wiggled a little bit then lightly moaned. This made my dick flinch and she moaned again.
I felt her hand reach and touch my throbbing cock. I wasn't sure if she was sleeping or not but I was definitely enjoying her touch. She hand then made it way into my shorts. I began to feel a little guilty about this so I started to roll over. I made it to my back and Rachel rolled over too, keeping her hand on my dick. "Don't leave me," she said. She kissed my neck and began to stroke me.
I knew this was wrong but it felt so good. I decided to touch her. My hand made its way to her ass. She lightly moaned again and her grip on my cock tightened. I moved my hand and lightly touched her pussy. Her moan was louder this time. When I did this, she let go of my dick and tugged at my shorts, wanting them pulled off. I instinctively raised my butt up and she pulled them down. She then got on top of me.
Rachel then reached down and pulled her thong to the side. She grabbed my cock and guided it to her opening. She was so warm and wet. She slowly lowered herself down on me. She was so tight. She exhaled sharply as she slid me all in. She raised up a little, put her hand on my chest and began to move up and down on me. There was just enough light that I could see her small breasts and the expression on her face, it was pure lust.
She began to pick up her pace and her breathing increased. It wasn't hardly a minute when I her Rachel say, "oh my, yes," Her pussy tightened and she came. Her orgasm brought my orgasm on and I came inside her. She kept pumping me until I quit shaking. She fell onto me, breathing hard.
"I can't believe that just happened. It felt so natural to be with you. Thank you for being here for me."
I grabbed her and rolled over on top of her, still hard inside her. I began to pump into her. She grabbed my wrists and squeezed me tight. I sucked on her small breasts as I fucked my sister. I fucked her to another orgasm and she wanted me from behind. She got on her hands and knees and I could see my cum dripping out of her. I fucked her to two more orgasms and I unloaded into her for a second time. We both fell onto the bed and almost instantly fell asleep.
I woke up with her laying on my chest. I kissed her forehead, waking her up.
"Good morning Rachel."
"Good morning. Thank you for comforting me last night, that was incredible. I'm definitely over that asshole now. Where does that leave us now?"
"I'm not sure but I'm excited to find out."
