The two of us returned to our bedroom in silence. I watched Lila, who was standing in front of the mirror. She didn’t say a word, only staring at her reflection in Mom’s body. She looked hesitant and confused. I knew what she was thinking.
“Victor ... I ... saw Dad’s cock fucking my body and ... I felt so horny.” Lila, in Mom’s body, turned to look at me, her eyes trembling. “Could you please fuck me, Victor, as hard as you can. Fuck me so I can forget dad’s cock,” she whispered.
I nodded slowly, and then we began to undress each other completely. I saw Mom’s body with my own eyes again. She was so beautiful and perfect in my eyes. I lifted Mom’s body and placed her on the bed.
With trembling hands, I started caressing Mom’s breasts, feeling their softness and weight. Then I moved down, my mouth exploring every inch of her body. I could feel the heat radiating from her sex, and I knew she was eager for me. I spread her legs wide and leaned in, my tongue finding her clit. Lila’s body jerked in response, and she let out a guttural moan that filled the room, “Victor ... Aaaaaaahhhhh.”
Her hips began to buck and rock as I worked my tongue around her, teasing and tasting. She was so wet and ready for me. I pulled back, lining my cock up with her entrance, and pushed in. Despite not being as large as Dad’s, her pussy felt incredibly good, wrapping around me firmly. I pounded Lila without stopping, fucking my mother’s pussy with my own cock was indescribable; this was just like having sex with her.
“Victor, good. I’m so horny,” she moaned. Her words almost made me cum instantly, but I kept fucking her until I felt my cum explode into my mother’s pussy. We both lost in the intensity of the moment. I held her tightly, our bodies still connected, as we both panted and caught our breath. The room was silent except for our heavy breathing.
Once our breaths had evened out and the tremors of pleasure had subsided, Lila looked up at me with a mischievous twinkle in her eyes. “Do you want to try ass fucking Mom?”
I nodded, and didn’t hesitate for long. Lila, in my mother’s body, turned over onto her stomach, presenting her round, firm ass to me. I spread my cum from her pussy over her tight asshole. My dick slid in easier than I thought it would. Maybe her ass had already been well used and accustomed to Dad’s larger size. It was so much tighter than her vagina.
The family relationships also changed significantly. Now, sexual matters have become a normal part of daily life. Dad and Mom in Lila’s body were often together without locking the door. Sometimes they would do it in the living room or even in the bathroom. Everything was open and explicit. No one felt ashamed or surprised anymore, because this kind of thing happened normally. Lila and I were the same. We started showering together to save water. Being together has become a part of life, like eating or sleeping. It was the way we relaxed and a source of happiness in what was left of our lives.
One night, when the air was especially cold, we spent time together. Dad played some old movies for Lila in Mom’s body on the projector in the living room. They sat huddled together on the large sofa. Dad put his arm around Lila, who was in Mom’s body. Meanwhile, I was teasing Mom in Lila’s body. I secretly took ice from my glass and poked her back, making her jump and turn around with a yell.
“Victor!” Mom quickly grabbed some ice and poked my thigh in return. I tried to run, but I couldn’t escape. Finally, Mom in Lila’s body and I started wrestling gently, just like I used to with Lila when we were kids. Only this time, I was doing it with Mom in her body. When my body pressed against hers, my penis became hard instantly, and Mom noticed something hard pushing against her butt.
So she cried out a warning, “Victor! Are you trying to fuck your own mom?” We both froze for a moment. Then we burst out laughing.
Later that night, when everyone had gone to bed, Lila and I sat on my bed, talking.
“He hugged me,” Lila said, her voice barely a whisper. She was still in Mom’s body, and the weight of it seemed to hang on her shoulders. “While we were watching the movie, he pulled me closer and grabbed my breast or mom’s breast, whatever.”
I listened, my eyes fixed on her.
“And he said he missed Mom’s body,” she trailed off, her gaze dropping to her hands. But then, a strange smile crossed her face. “I told him, ‘If you miss her, you can just keep doing it. It’s Mom’s body anyway.’ Then I laughed. He just looked at me all confused, so I told him, ‘You’ve already fucked me in Mom’s body anyway, haven’t you?’”
“And how did you feel when he did that?” I asked.
“I actually miss his body, too, Victor. Especially, after you used his body fucked me countless times,” she whispered, a heartbreaking confession. “I miss being held by his hands. I miss his massive cock.”
Our story continued in this confusing way. Lila in Mom’s body, and I spent every night together, along with Dad and Mom in Lila’s body. None of us cared when we would get back into our original bodies anymore. No one cared about morality either. Dad certainly wasn’t judging from how hard he fucked Lila’s body. Who would care when this world was collapsing? Morality had collapsed along with humanity. But love and lust still stood strong, above all fake morality.
As time passed, we grew accustomed to the silence with no signals from the outside world. Sometimes I would go and look at the small air vent, which was the only way to see outside. On some days, I would see a shadow of something moving in the sky. It might have been a plane, or something we didn’t know. But mostly it was just emptiness. Some days, a loud noise would come from a distance, similar to the sounds of combat we used to hear on the news. Every time the noise subsided, Dad would go out and check the systems inside the bunker, the electricity, the water, the ventilation, to make sure everything was still working normally. But no one was brave enough to go outside again, because the last news we received from the government was that there might be germs or radiation contamination in the air in the combat zones.
One evening, Lila and I were in our room. I was pounding into Mom’s body. We were both so close to climax when suddenly, Lila’s breath hitched. I thought it was the sweet sound of her approaching orgasm, but then she froze. Mom’s eyes, wide and filled with horror, stared into mine as I was pumping my cum into her. It was as if she had just realized what was happening.
“Victor, stop! It’s me, your Mom,” she begged. I pulled out immediately, my heart racing. I saw my semen leak out from Mom’s pussy as I realized that she had regained her own body.
“Mom? Are you back?” I stuttered, not knowing how to react.
“Yes, Victor,” she said, her voice filled with a mix of fear and relief. “I got back when you started to ... to ... shoot your ... your ... cum inside me,” she stuttered.
I looked at her, my heart racing. “What do you remember, Mom?”
Mom looked down at the floor, blushing. “Oh ... shit. When it happened, I was being fucked by your Dad.”
Mom and I looked at each other in shock. Then we bolted from the room, rushing to the master bedroom. We passed through the door, and sure enough, there they were, Dad fucking Lila. His monstrous cock slammed into her, and she was taking it with pleasure.
“Dad!” I exclaimed at once. “Mom and Lila are now swapped back!”
Dad, still lost in his passionate thrusts into Lila’s body. His eyes never left hers, and she stared back at his as if they were two animals mating in heat.
“He knew. I told him,” Lila said, her voice filled with lust. “Don’t stop, Dad. Fuck me harder.”
Mom and I exchanged glances. She looked as stunned as I felt. Lila seemed to be enjoying herself immensely. Her moans grew louder and more desperate with each of Dad’s thrusts. Her eyes rolled back into her head as she reached her peak, her pussy contracting as she got climax on Dad’s cock.
Mom and I stood there, our own bodies tingling with arousal. We couldn’t help but watch as Dad’s cock thrusted into my sister’s pussy, burying himself deep inside her as he filled Lila with his hot, thick seed.
“Yes, Daddy. Cum inside me. I miss your cock so much.” Lila’s voice was thick with pleasure, and she didn’t bother hiding her delight. I couldn’t believe my sister was enjoying this so much.
