I fucked my sister’s best friend after she told me to

I (19M) and my sister (18F) were at home and she told me she was going to have her best friend (18F) over for the night. She told me they were going to drink and asked me if I wanted to join them. Of course I agreed. My sister's best friend is super hot, about 5'7'', skinny but still has a nice ass, with long black hair. So I went with my sister and picked up her friend from her house.

When we got there she got in the car with a bag and pulled out a bottle of fireball. "You look ready to have fun tonight" my sister said. "I'm ready to get drunk as hell" she said. "Is it ok if I join you two" I asked. "Of course you can" her friend said. "Ok once our parents go to bed do you want me to come to your room?" I asked. "That's sounds good" my sister said.

So we get home and wait until my parents go to bed around 10:30pm and then I go to my sister's room. My sister's friend pulls out the bottle and puts three shots. We take the shots and talk. "I can't believe my boyfriend broke up with me" her friend said. "Would you break up with me" she asked me. "Uhm no I wouldn't" I hesitated. "You're so sweet" she said and then hugged me. Her stomach was pressed against my crotch. Luckily she let go before I got hard.

So we kept drinking and my sister and her friend started twerking. I saw my sister's friend's ass and bouncing and started to get hard.

After a while we sat and talked and then my sister told her us something crazy. "You guys should fuck" I was so surprised I didn't even know what to say. "I don't know" I said. Her friend didn't say anything but looked at me and smiled.

About half an hour later I was hungry so I decided I'm gonna walk to McDonalds "do you two want anything." I asked. My sister said she didn't want anything but her friend said she'd go with me. "Ok" I said and we left.

My sister's friend was very drunk and so was I so we held each other up the whole way there. We went and got some food and on the way back I was able to carry her so she wouldn't fall. When we got back to the house she gave me another hug "thank you for coming with me" she said. While we were hugging she reached down and touched my dick. "I've wanted to do this all night" she said. "Do you want to do this?" She asked. "Of course I do" I said. "Do you want to go to my room?" I asked. "Yes let's go" she said. So we went back in to the house and went to my room. I had to carry her so I picked her up and she wrapped her legs around me. I had never been this hard in my life.

We got to my room and I put her on the bed and got on top of her and we made out for a while. Then I pulled down her shorts moved her panties to the side and started to eat her pussy. "Oh my god your tongue is so good" she said. Then I put two fingers into her pussy while I licked it. She moaned so loud I thought we were gonna get caught.

After a while she told me "I wanna suck your dick" so I pulled down my pants and my dick jumped up hard as a rock. (My dick is almost 8 inches and bends downward) She started sucking my dick and it felt so good. "You're amazing at this" I said. "I want you to fuck me right now" she said. She didn't have to tell me twice.

"Bend over" I told her. She got on all fours on my bed. "You ready" I asked. "Put it in me" she responded. So I slid my dick in her pussy and started fucking her doggystyle. Her ass was bouncing off me and it looked amazing. I squeezed her ass while I was fucking her. We both were moaning so loud.

I asked her "what position do you wanna do it in". "Speed bump" she said. So I pulled out and she laid down and I got on top of her. I slid my dick in and started fucking her. "This feels even better" she yelled. "Shhh you're gonna get us caught" I said. We kept fucking. "I'm cumming" she yelled. "I'm about to cum too where do you want me to" I asked. "Cum on my ass" she said. I pulled out and came on her perfect ass. "I wanna taste it" she said. So she rolled over licked the tip of my dick. "It's a little salty but it's good" she said. "I wanna taste some more" she said. And then she used her hand to wipe up the cum on her ass and swallow it.

"I can't wait to do this another time" she said. Me either" I said.
