This is a true story about hearing my sister having sex. We didn’t get along most of the time growing up but I’ve at all times felt a sexual attraction towards her, since her body starting to develop. I had several friends that would make comments about how hot she was.
She was about 5’ and her breasts were a B or C cup, She at all times wore extremely short/tight clothes. My favorite time to stare at her was in the mornings because she would just wear underwear and a t-shirt to sleep and would come eat breakfast dressed like that before getting ready for the day.
We lived in a two story house and our rooms were right next to each other on the bottom floor. Our parents room was on the top floor, along with our younger brother’s room.
We went to separate schools because I went to an all guys college and she went to a co-ed college so I didn’t really know all of her friends.
I like gonna the gym later at night when it’s less crowded. This particular night, I came home from the gym and a car pulled in the driveway behind me. Two guys I didn’t know got out of the car and, at first, I wondered I was about to get robbed or something. One of the guys said that my sister invited them over. I wasn’t gonna let random guys into our house so I told them to wait and I’ll go check with her.
I went to my sister’s room and knocked on the door. She answered and was dressed in her usual bedtime clothes, t-shirt and underwear. I asked her about the guys outside that were here to see her and she said yes she invited them over. I told her “well they’re outside,” and she went up to get them still only wearing her t-shirt and underwear.
I went into the bathroom to get ready for bed, but I heard my sister and the two guys talking and laughing as they walked to her room and close the door. I finished getting ready for bed then went to my room.
For about a half hour, I could hear the guys and my sister talking and laughing through the shared wall of our rooms. Then I started hearing some moaning and grunting sounds. Obviously now I couldn’t fall asleep because of the noises. I couldn’t really hear clearly what was being said, but I heard a lot of “oh fuck,” and the squeaking of her bed. Plus I’m sure they were trying to be quiet because our parents were sleeping on the upper floor. This went on for several hours with some breaks in between so I know there was a few rounds of sex. I couldn’t sleep so I stayed up jerking off listening to my sister getting railed by two guys in the room right next to me.
Around 5 o’clock in the morning, I heard my sister’s door open and some talking as she walked the guys to the door to let them out before our parents got up.
The next day, obviously my sister and I slept late because both of us were up late, her getting fucked and me being kept awake from the sounds. When I woke up, my sister was sitting at the kitchen table in the same t-shirt and underwear she had on the night before. It was pretty awkward when we greeted each other that morning, but neither of us said anything about the night before.
Before anyone asked, no I never had a sexual relationship with her. I did see her naked a few times though because we shared the bathroom on the lower floor of our house. This wasn’t the only time I heard her having sex but probably the one that I jerk off to the most even still. I never saw those two guys again and I have no idea if she ever did.
NSFW: yes
