We got caught by my gf’s sister best friend [MFF]

So this story happened during my girlfriend's (Maria) sister's (Ana) birthday party. Ana organized a dinner at her parents' house to celebrate her birthday and invited some friends and family. Of course, some of us abused on drinking and Ana's best friend (let's call her Marta) and I slept their. I slept with my girlfriend Maria in her room and Marta slept on the sofa in the living room. Ana hates sleeping with other people and didn't let her best friend sleep with her in the room.

So far so good. Around 2am we all went to bed. Everyone was already tired and Marta was eager for us to go to the bedrooms so she could feel comfortable in the living room to sleep. We went to Maria's room and lay down on the bed. We fell asleep straight away but at 4am I woke up to go to the bathroom and when I went back to the room, I accidentally woke up Maria. I lay down next to her on the bed again and after a few minutes I hugged her from behind and took the opportunity to put one hand under her top so I could feel one breast and started squeezing her nipple. She was getting horny but told me that we couldn't do anything because there were a lot of people in the house and her bed would make a lot of noise if we started fucking.

So I asked her to get on the rug in front of her bed and fuck on the floor. She went crazy with the idea and we started kissing and taking off our clothes while still in bed until when the moment came that I wanted to stick two fingers in her pussy, we went onto the carpet. She lay down on the carpet on her back and opened her legs for me and I stood next to her on my knees in a great position to masturbate her. I stuck two fingers in her pussy and she covered her head with a pillow so no one could hear her moans.

Seeing her in that state made me so horny that with my free hand I started jerking off. At that moment I just wanted her to suck my dick, so I took the pillow away from her. and I got on my knees on top of her close to her face so she could suck me. She started sucking my dick while masturbating at the same time. What an amazing feeling! Me on top of her face getting a blowjob and she with two fingers in her pussy! And it was at that moment that what we weren't expecting happened. When I went to the bathroom I didn't lock the bedroom door again. Marta (Ana's friend) was cold in the living room and went upstairs to Ana's room to get a blanket.

The problem is that Ana's room is right next to Maria's room and anyone who doesn't live there always gets it wrong. So she went up the stairs and as she thought she was going into Ana's room, she didn't even touch the door, she just walked in... and saw the two of us on the bedroom floor and my dick stuck in Maria's mouth... She didn't even know what to say, she was shocked. I got off Maria straight away, we got back to bed to cover ourselves and apologized for being in those preparations in the middle of the room. After about 30 seconds of looking at us without reaction, Marta said what we weren't expecting her to say. She said it was her fault and that we didn't have to be ashamed at all because it was the most exciting scene she had ever seen in her life. Then she entered the room, closed the door and asked if she could watch.

Maria and I looked at each other until I told her that it was fine with me. Maria still reflected a little and agreed, but Marta would have to sit in an armchair in the corner of the room and she wouldn't be able to leave it. She agreed and we went back to the middle of the floor… I told Maria that I was loving her blowjob and we went back to the same position.

After about 2 minutes we had already forgotten that Marta was in the room because of so much excitement... I got off of Maria, she got on all fours with her ass facing me and I started fucking her doggy style position... It felt so good when I remembered that Marta was there too and I turned back to see what she was doing... She was in the chair with her breasts out and masturbating with her legs open facing me …as soon as I saw this I went crazy…. I picked Maria up, placed her against the wall next to the armchair and fucked her with all the strength I had against the wall while looking at Marta who was next to me masturbating.

After a short while I couldn't take it anymore and I came all over Maria's cunt... she also came at that moment... and we had already finished fucking but Marta hadn't cum yet so she continued masturbating... me and Maria watched her fingering herself until after about 2-3 minutes she started squirting all over the armchair! It was a crazy night! After she came, she gave us both a kiss and left the room. We never spoke about it again. But i will never forget that crazy night 😍
