Was it the right choice?

I was just about to turn 18 when mother died from complications during surgery. My sister was only 14 and our mother was our last blood relative. While my mothers boyfriend of 5 years didn’t mind if we stayed with him, legally he couldn’t without adopting and my sister would go with state til he could adopt her. Our alternative was I take custody of my sister. He offered we take that route and stay in same home so no moving schools. In exchange we would help raise our half brother. A year into us staying there we caught him fucking my friend from college Alexis. We were with our little brother at park when she came over looking for me. When we got home I recognized her car in driveway but due to their vocalizations of the fun they were having we were inside without them aware.

I called her from living room but it buzzed on table in kitchen, which nearby was her underwear. Enraged I burst into the room to see him holding her in his arms fucking her. I threw her phone down and said you missed a fucking call. She was shocked but he didn’t stop, he looked back at me and asked me to close door while he continued to slam his dick into her. He set her down as I closed the door and I saw why my mother ate out of his hand. A massive gorgeous cock. Maybe 8 inches and it looked thick, I felt my pussy tingle and I switched back to anger as I heard her cry out again.

After the slapping of skin ended, he walked out in sweatpants. She’s gonna nap a moment, he informed me. I went to check on her and she was still naked passed out. Her pussy lips bright red from the fucking, The cum tho was leaking out her ass, he fucked her in the ass and she was screaming for joy? This fucking slut, I slapped her across face but she barely moved. It wasn’t planned if that makes you feel any better. I was hard when she came over, said no way that’s what I think it is. One thing lead to another, as he jiggled his cock at me. My eyes transfixed on it…. Yeah I bet, subconsciously I reached for him. He closed the distance and I grasped it. Now kneel down and worship it til I’m hard so I can fuck you. I’d given two blowjobs by now but never to a cock so thick. I mostly worked the head and stroked him.

Alright stand up and bend over he instructed. As soon as I bent over he placed his hand on my shoulder and the head of his cock against my lips. I was so wet I began to slide onto him, then once he had every inch of me he stopped for what felt like forever. Then proceeded to pull all the way out and slam it into me. The pace picked up til I thought I might pee and I asked to stop to pee and he just fucked me harder. That’s when it began, dripping down my legs, he loved it and fucked faster. My legs began to vibrate and he laid me belly down next to Alexis and told me to eat her pussy or it was going in my ass. I began to eat her sweaty salty pussy as he fucked my relentlessly. He pulled out and pulled my hair back, cumming in my mouth.Later that night he fucked me again and finished in my ass anyway.

The next morning I woke to screams again, but Alexis was watching my brother. I slowly walked across the house. Outside my little sisters door I hear the same sounds, just the pounding of bodies and my sister losing her mind. Cum in my ass daddy. Cum in my ass daddy. Wait that’s not her voice. I opened the door to see her riding him while watching me beg for his cum in my ass. I moved out 3 years later but Alexis and my sister still live there. I do miss the sex, but refuse to share a cock with my sister and former best friend.

We had many amazing sessions and memories but I’m a jealous bitch.
