Our younger Sis secretly watched us fuck

I had thought it would only happen in my fantasies but my dream came true now: my brother and I were constantly doing naughty things without our parents n sister noticing. He would squeeze my tits n pull nipples, caress my ass while I would rub on his cock with my hands or ass while watching movie on the couch.

I mostly sneak into his room late night after I make sure that our sis is asleep. Last night it was way past midnight when I got a chance to go. I love surprising my bro, so I slowly opened the door and saw that he had dozed off. He mostly sleeps naked and his cock was softly resting on his lower belly.

I sat down on the edge of the bed. I pulled my nightie away from my body. I slowly reached out and touched my brother's cock. He stirred for a moment but he didn't wake up. I lowered my face and I took my brother's cock in between my lips. That what it took to wake my brother up with a smile on his face. He placed a hand on the back of my head n pushed down. I was bobbing up and down his cock. His dick was soon standing at attention. I couldn't waste this moment. I pulled away and I climbed up over top of my brother's body.

I took his stiff cock in my hand and I aligned it with my wet slit. I lowered my body until my brother entered me. Fuck, did that feel good! He was stretching me out. We went slow at first. Bro had his hands on my hips. He was pushing his cock deep into my belly. I remember crying out as he filled me with his hard cock.

At that moment, I noticed that the door was slightly open and i could see a shadow. I continued riding his cock and discreetly tried to see who it was. I gasped as I realized that it was our 19 year old younger sister. I bent over n whispered to my bro about what I saw n asked him to act normal. I felt my pussy tingling and more wet while my Brother's cock also felt harder as we both felt more excited that our lil sis was watching us..

My brother took his hands from my hips and he started to massage my medium sized breasts. I love it when a man fondles my pert tits. He was pinching my nipples as he fed me his cock. I could see from the corner of my eye that my sis had one hand inside her panties and the other was squeezing her petite breasts. I again whispered to my bro n he got more excited. I was having these small orgasms at first, but as he took me harder, my orgasms grew. My body was starting to shake as he drove his cock deeper into my pussy. You could hear the slapping of skin as we fucked like two crazed teens.

My sis too had her eyes closed n I could see her hand moving fast in n out inside her panties. All of us were nearing our orgasms, so I whispered my wish to bro. He nodded and pulled his cock out and I got on my knees and positioned myself in an angle where our sis could see the cumshot clearly. I could see my lil sister's eye pop out when she saw our bro spray a huge load on her big sister's boobs, face, tongue n open mouth. I saw her squirm and put her hand on her mouth to muffle her scream from her orgasm. She then closed the door and left quietly. Oh that was so satisfying!! Stay tuned for more...
