I am 19F, and my brother and his girlfriend are 24F and 26M. One day, when I was playing games in my room, our parents told us that they were taking a week-long vacation. My brother and his girlfriend, who we'll call Kenny and Aria, became very suspicious as I helped them move their things into the car. His girlfriend in particular was staring at me, which was odd, but I decided to ignore it and went to my room. It goes without saying that being upstairs by myself allowed me to masterbate anytime I wanted to, as their room is below and I don't make a lot of noise when I'm madterbaiting. My door was still open.

I was rubbing my pussy and watching porn on my TV when I received a text from my brother asking if I could come down. I sighed, turned off the TV, and put on my shorts, but as soon as I opened the door, they were both standing here, and I thought, "Uhm, what the fuck?" My brother asked if I could do his girl friend's nails because I work as a nail technician, so I said yes and let her into my room. He sat on the couch outside while I was getting ready. When his girlfriend sat down in front of me, I started to feel a bit uneasy because my pussy was still moist and sitting on a hard chair wasn't helping. She then lifted her leg and touched my thigh. When she did it again, I thought it was an accident, but when I looked at her, she was on her phone. I shook my head and carried on, but as I heard the door close behind me, I stopped and turned to ask my brother, "What are you guys doing?" They grinned and said they wanted a threesome when I inquired.

I told them that I was confused and that it would be weird, but apparently Aria wanted this since she found me attractive. I accepted their rejection since I wanted to try everything and I was naive at the age of 18.We all undressed, and my brother was sitting on my bed, jerking away, as soon as Aria made out with me. Our bodies were smashed against each other. Aria is a gorgeous woman with a fantastic figure that includes huge tits and an ass, and caramel complexion like mine.

As I hesitated to suck my brother off, she laid me down and ate me out. I let out a loud groan when Aria sucked on my clit, giving my brother an opportunity to put his cock in my mouth. His girlfriend was devouring my pussy so well that I had to hold back on cummig, but I finally failed because I came forcefully, which led to my brother finishing on my face. His hands were all over my body as I groaned and ravenously swallowed his dick.

As my brother took Aria and fucked her, I sat up and watched. It was so freaking amazing to witness. After that, my brother grabbed me and kissed me, and I returned the kiss, feeling his tongue in my lips. It stung at first, but when Aria kissed me again, it felt amazing. Aria kept shouting, "Fuck your sister baby," which made him draw away from her and toward me. My brother called me his whore of a sister and gave me a hard slap on the ass.

I eventually approached him, and my brother helped me down. As we came together, I practically squirted from the way he fucked my pussy. Since I was riding him while his girl watched and stroked herself, I'm glad I'm taking medication. I was so tired that I laid on the side as they fucked. I spread my pussy and begged Aria to trib with me after a time since I needed more. My brother watched on his phone, capturing everything as she climbed on top of me and we shared a kiss.

Aria began to grind against me, and I groaned out and reciprocated. We continued to grind, kiss, and slap each other until she dubbed me her slut and we came together to sucking each other's tongues. We bathed and cleaned ourselves, and they said we would fuck again tomorrow. My pussy is soaked from writing, so I might send them a surprise video.
