I have two sibling who are identical twins. My sisters Sarah and Sasha at all times did things together. My parents made me responsible for them because I was the oldest sibling. My parents were both doctors and worked hours on end. We got along fairly well like ordinary siblings do. After I graduated high college, I landed a nice job in an IT firm which worked out well because I was relatively good with computers. When COVID came around, my parents were hardly around and I started working remotely from home, only having to go to the office once-twice a week.

Sarah and Sasha, who were seniors, would at all times cause some sort of ruckus after college while I was working. I saved enough vacation days to take a whole week off work. I asked Sarah and Sasha if they wanted to get some food. We got home and we did our own thing as I watched some TV as I ate. I was going up to my room, I heard slight moaning coming from Sarah and Sasha’s room. I wanted to crack the door, but it was locked. Knowing they were doing something sexual, like eating each other, I wondered about it and fantasized which actually got me hard. I figured I just had to jerk to rid myself. But as days went by, these thoughts and images of my sisters were torturing me.

One day, I was watching porn and masturbating. I didn’t hear Sarah because I was wearing headphones, but while I was finishing, I saw my door close. Knowing my parents weren’t home, I went to Sarah and Sasha confronting them. I asked them, “we’re you both spying on me?”
Sarah nodded yes and said, “I was, Sasha didn’t. I thought it was kinda hot. So I just watched and you didn’t notice because of your headphones.”
“Alright, whatever. I know you guys do it too,” I blurted.
“Huh? Wait, what do you mean?” Sasha asked.
“Yeah, tell us. What is it?” Sarah added.
“Well, I heard you gals about month ago and with nobody else in our house, you had to be playing with each other. I’m not stupid.” I said. Sarah and Sasha looked ashamed, but I told them, “look it’s okay. I won’t tell mom and dad. You saw me and I heard you gals, now we can just move on.”

Sarah and Sasha looked at each other whispering, then looked at me. “What were you two talking about and what’s wrong?” I asked.
“Let’s all play together. We never had a guy join us, “ Sarah said. I paused, but as they got undressed, my cock started to get hard as I gazed my eyes on their bodies. As they kissed each other, Sasha went for my cock and pulled it out. As Sarah and Sasha shared my cock, they were taking turns sucking while the other sucked on my balls. As I was getting close and my cock started to throb, Sarah put my cock in her mouth as I released, she then kissed Sasha as they shared my cum between the two of them. I let them kiss as they laid down and as I got my erection back, I first ate out Sasha from the bottom, then slid my cock into her wet pussy as she moaned and squealed. As I continued to fuck Sasha, Sarah sucked her tits and played with her clit while I kept pounding away sending her to an orgasm as she shrieked. Sasha got off my cock as she was gasping trying to catch her breathe. Sarah began sucking my cock as she wanted her turn. Sarah got on all fours as I ate her out, then started to fuck Sarah. Sarah moaned and squealed like Sasha did, except Sarah wanted in rougher, telling me to fuck her harder and pull her hair. I did as Sarah asked, I then flipped her over and fucked her missionary while going balls deep as she was screaming out until she came. They wanted me to lie down as Sarah sat on my face, Sasha rode my cock, and they made out while doing so. Eventually, I started thrusting into Sasha as she orgasmed once again. Sarah wanted the same, so I let her ride me and as I thrusted, I felt my myself about to cum. After thrusting into Sarah a couple more times, I pulled my cock out, stood up, and jizzed on her tits. Sasha licked the cum off Sarah as I went to clean up.

I never expected this to happen, but I’m glad it did. With my parents gone most the time, we played at all times, but not at all times sex because they said they didn’t like it when they’re sore. But they at all times got me off as I got them off.
